Description

Field of the invention

The present invention relates to a reduction in power consumption in electronic devices. More particularly, the present invention relates to a circuit and method for decoupling a power output from a power input in a power module, a wallplate system, and / or a multiple socket in the presence of idle conditions.

Background of the invention

The increasing demand for more energy-efficient and environmentally friendly consumer devices has sparked interest in "green" or green technology power supply circuits. For example, a notebook's power adapter that is continually "plugged in" is idle for an average of 67% of the time. Even with a power adapter that meets the legal requirement of less than 0.5 watts / hour, this extended run time per adapter is 3000 watts of wasted energy per year. If the wasted energy of the numerous idle power adapters is taken into account, the lost power is considerable.

Each consumer device and each network adapter in a commercial or residential building is in some way plugged into a socket of a wall plate. The standard wall plate has two sockets, but there are variations that range from a single outlet to more than two sockets. In an office or home environment, a computer, a screen, a printer, a scanner, and other electronic devices are connected to the wall plate. When these connected devices are not in use, they are often left on and independently change to idle operating conditions, which typically consume less than 1 watt per device. Although each device consumes standby power, the total power delivered by the wall plate may be equal to the number of used outlets times idle power, possibly 4 watts or more. Similarly, multiple sockets are used to multiply the number of AC outlets available from a single AC outlet. In an office or home environment, a computer, a monitor, a printer, a scanner, and other electronic devices are often connected to the same multiple socket.

When these connected devices are not in use, they are often left on and independently change to idle operating conditions, which typically consume less than 1 watt per device. Even though each device consumes standby power, the total power delivered by the multiple socket can be equal to the number of sockets used, times idle, perhaps 6 watts or more. This large amount of wasted idle power can be reduced or eliminated if the wall plate or multiple socket is adaptive or programmable to detect the idle state of each outlet and turn off that socket in case of no-load conditions.

Summary of the invention

According to various aspects of the present invention, a method and circuit for reducing power consumption of a power module, a wall panel system, a multiple socket, and the like during idle conditions are provided. A load state controlled power module may be configured in one example embodiment to reduce or eliminate power during an idle mode by decoupling at least one power output from a power input. A power module may be connected to one or more power outputs and to a power input that may provide AC power to the one or more power outputs. The power module may include a current measuring system, a control circuit and a switch. The current measuring system provides an output power value signal that is proportional to the load on the power output. If a behavior of the current measurement system indicates that at least one power output draws substantially no power from the AC power input, in one exemplary embodiment, the switch enables the power input to be disconnected from such a power output.

In an exemplary embodiment, a wall panel system is configured to reduce or eliminate power during an idle mode by disconnecting at least one power outlet from a power input. A wallplate system may include one or more outlets and one or more wallplate circuits, with an AC power input connected to the outlets through the wallplate circuit (s). The wall plate circuit may include a current measuring system, a control circuit and a switch. The current measuring system provides through the switch an output power signal that is proportional to the load on the socket. If a behavior of the Current measuring system indicates that at least one outlet draws substantially no power from the AC power input, the switch allows in one exemplary embodiment, the decoupling of the power input from such a power outlet.

The wallplate system may further include both a standard wall plate and circuitry to reduce power during an idle mode. The wall panel circuitry may be housed inside and on the back of a standard wall panel. In another embodiment, the wallplate system may be a wallplate adapter configured to fit over and connect to a standard wallboard. The wall plate adapter can connect to the standard wall panel by plugging it into either one or more than one of the standard wall panel sockets, and an electronic device can be plugged into the wall panel adapter rather than the standard wall panel.

In an exemplary embodiment, a multiple socket is configured to reduce or eliminate power during an idle mode by disconnecting at least one power outlet from a power input. A multiple socket may include one or more receptacles and one or more receptacle circuits with an AC power input connected to the receptacles through the receptacle circuit (s). The socket circuit may comprise a current transformer, a control circuit and a switch. In an exemplary embodiment, the secondary winding of the current transformer provides an output power value signal that is proportional to the load on the outlet. If a behavior of the secondary winding of the current transformer indicates that at least one outlet is essentially drawing no power from the AC power input, in one exemplary embodiment, the switch allows the primary circuit of the current transformer to be disconnected from such an outlet.

In accordance with various aspects of the present invention, a power module is disclosed that is configured to reduce or eliminate power by disconnecting a power input. In an exemplary embodiment and with reference to FIG 1 has a power module 100 a power input 110 , a power output 120 and a power module circuit 130 on. Consequently, the power module 100 have any system configuration in which a power input is received, power is provided at a power output, and a circuit decouples the power provided to the power output to reduce power consumption.

In an exemplary embodiment, the power input is 110 and the power output 120 by 3-pin or 2-pin plugs or sockets. In another exemplary embodiment, the power input 110 and the power output 120 free connecting cables for connection to various electrical components.

However, the power input can 110 and the power output 120 be suitably configured in any other input and / or output configuration. Furthermore, the power input 110 in an exemplary embodiment, be connected to a 110 volt or 220 volt power source.

In an exemplary embodiment, the power module has 100 the power Entry 110 communicating with the power module circuit 130 is coupled, in turn communicative with the power output 120 coupled is how it is in 2 is shown. The power output 120 may also be connected or otherwise coupled to a ground line and a neutral in one embodiment. The power module circuit 130 has a current measuring system 231 , a control circuit 232 and a switch 233 on. In an exemplary embodiment, as well as for illustrative purposes, the current measuring system 231 a current transformer 231 (ST) with a primary circuit and a secondary winding on. The current measuring system 231 however, it may also include a resistor having a differential amplifier, a current sensing chip, a Hall effect device, or any other currently known or subsequently developed suitable component configured to measure current. The current transformer 231 supplies to the control circuit 232 an output power value signal that is proportional to the load on the power output 120 is. Further, the switch provides 233 a connection between the primary circuit of the current transformer 231 and the power output 120 ago.

In an exemplary embodiment, the control circuit 232 at least one or a combination of the following: a latch circuit, an analog circuit, a state machine and a microprocessor. In one embodiment, the control circuit monitors 232 the state of the secondary winding of the current transformer 231 and controls the operation of the switch 233 , In an exemplary embodiment, the control circuit receives 232 a low frequency or DC signal from the current transformer 231 , The low-frequency signal can be, for example, 60 Hz. This low frequency or DC signal is provided by the control circuit 232 as the current interpreted by the load at the power output 120 is needed.

The control circuit 232 may have various structures for monitoring the state of the secondary winding of the current transformer 231 and controlling the operation of the switch 233 exhibit. In an exemplary embodiment and with reference to 3 includes the control circuit 232 a current sensor 301 and a logic controller 302 , The current sensor 301 monitors the output of a current measuring system, such as the secondary winding of the current transformer 231 , which is an AC voltage that is proportional to the load current. Also provides the current sensor 301 a signal to the logic controller 302 , In one embodiment, the signal may be a DC voltage that is proportional to the current flowing through the current sensor 301 is monitored. In another embodiment, the signal may be a current that is proportional to the current flowing through the current sensor 301 is monitored.

In an exemplary embodiment, the logic controller is 302 powered by an energy storage capacitor. The logic controller 302 can briefly connect between the storage capacitor and the power input 110 to supply a power supply to the logic controller 302 continue. In another embodiment, the logic controller 302 be powered by a battery or other power source. This energy source is also referred to as household or hotel services; it acts as a source of low auxiliary power. In one embodiment, auxiliary power is received from the power input 110 taken. For further details on similar current monitoring, see U.S. Provisional Patent Application 61 / 052,939 entitled "Circuit and Method for Ultra-Low Idle Power," which is hereby incorporated by reference.

In an exemplary embodiment, the logic controller is one 302 to a microprocessor, before and after integration of the power module 100 is programmable in an electronic device. In one embodiment, a user may connect to the logic controller 302 and the parameters of the power module 100 Customize. For example, a user may set the threshold and a sleep mode duty cycle of the power module 100 to adjust. For example, data regarding past power consumption and / or energy saved from the power module could be used 100 be transmitted. The bidirectional data transfer between the power module 100 and a display device may be achieved by a wireless signal, such as an infrared signal, a radio frequency signal, or other similar signal. The data transmission may also be accomplished using a wired connection, such as a USB connection or other similar connection.

According to an exemplary embodiment, the control circuit 232 also a power separation 303 having the logic control unit 302 communicates. The power separation 303 is designed to be the logic control unit 302 from the power input 110 to separate or electrically isolate and reduce power loss. While the logic controller 302 is separated, she is through the Storage capacitor or other power source powered and the logic controller 302 enters a sleep mode. If the storage capacitor reaches a low power level, the power disconnect is 303 trained to the logic controller 302 again with the power input 110 to reconnect to recharge the storage capacitor. In an exemplary embodiment, the power disconnect is 303 capable of reducing the power loss from a microampere leakage current to a nanoampere leakage current.

In another exemplary embodiment, the control circuit receives 232 a control signal corresponding to the power input 110 is impressed by another controller. The control signal may be, for example, the X10 control protocol or other similar protocol. The control circuit 232 can the control signal through the secondary winding of the current transformer 231 , from a coupled power input 110 or any other suitable device currently known or subsequently developed which is adapted to receive the power input 110 with the control circuit 232 to pair. This control signal may be from within the power module 100 come from or may come from an external controller. The control signal may be a high frequency control signal or at least a control signal having a frequency different from the frequency of the power input 110 different. In an exemplary embodiment, the control circuit interprets 232 the high-frequency control signal to the switch 233 switch on or off. In another embodiment, an external controller may transmit a signal to the power module 100 into a "switched on" or "switched off" state.

In an exemplary embodiment, if a behavior of the secondary winding of the current transformer 231 indicates that the power output 120 essentially no performance from the receipt of power 110 pull, enable or control the switch 233 the decoupling of the primary circuit of the current transformer 231 from the power output 120 , In other words, the switch allows 233 disconnecting a power source from the power outlet 120 , In an exemplary embodiment, the secondary winding of the current transformer 231 to an AC waveform at the AC line frequency of the power input 110 monitored, wherein the AC waveform has an effective voltage or RMS voltage that is proportional to the load current passing through the primary circuit of the current transformer 231 to the power output 120 flows. In another embodiment, the AC waveform is rectified and filtered to prevent it from being received by the control circuit 232 to generate a DC signal. The DC signal is proportional to the load current passing through the primary circuit of the current transformer 231 to the power output 120 flows.

In one embodiment, the phrase "substantially no power" is intended to convey that the output power is in the range of approximately 0-1% of a typical maximum output load. In an exemplary embodiment, the switch 233 designed to connect the primary circuit of the current transformer 231 with the power output 120 to control, and has a switching mechanism to the primary circuit of the current transformer 231 from the power output 120 essentially decouple. The desk 233 can have a relay, a latch relay, a TRIAC and an optically isolated TRIAC.

By the primary circuit of the current transformer 231 is essentially disabled or disabled, the power consumption at the power output 120 reduced. In one embodiment, to deactivate the power output substantially means that the output signal of the secondary winding of the current transformer 231 through the control circuit 232 was interpreted as sufficiently low, so it is appropriate to the switch 233 turn off and power from the power output 120 to remove.

In another exemplary embodiment, and with reference to 2 and 3 , indicates the power module circuit 130 Further, a reconnecting device 234 formed to close the switch 233 through the logic controller 302 to enable. Closing the switch 233 connects the power output 120 again with the primary circuit of the current transformer 231 and the power input 110 , In an exemplary embodiment, the reconnect device 234 a switching device which can be closed and opened in various ways. For example, the reconnecting device 234 have a push button that can be operated manually. In one embodiment, the push button is on the front of the power module 100 positioned. In another embodiment, the reconnecting device 234 through itself through the power input 110 moving signals representing the control circuit 232 interpreted as an on / off control, remotely influenced. In yet another embodiment, the reconnecting device 234 controlled by a wireless signal, such as an infrared signal, a radio frequency signal or other similar signal.

In an exemplary embodiment, and with reference to 3 and 4 , indicates the power module circuit 130 a reconnect memory state 304 on. The reconnect memory state 304 is designed to indicate whether the reconnecting device 234 has been activated lately, so the logic control unit 302 when switching on the circuit states can determine. In the exemplary embodiment, the reconnect device storage state 304 a capacitor C5 which charges when the reconnecting device 234 is activated. The logic controller 302 can then measure the voltage across the capacitor C5 as an indication of whether the reconnection device 234 was activated. In an exemplary embodiment, the reconnect device storage state provides 304 a digital reading to the input PB1 of the logic controller 302 , If a sufficient voltage is applied to the capacitor C5, the input PB1 reads a "1". If no sufficient voltage is applied to the capacitor C5, the input PB1 reads a "0". The determination of which voltage is sufficient depends in part on the ratio of the resistors R6 and R7 and may be determined by the logic controller 302 interpreted as one skilled in the art. The capacitor C5 serves to change the state of the reconnecting device 234 store until the voltage of the capacitor C5 through the logic control unit 302 can be read.

According to another exemplary embodiment, the switch 233 automatically operated on a regular basis. For example, the switch 233 automatically reconnect after a few minutes or tens of minutes, or any more or less frequent period of time. In one embodiment, the switch 233 Automatically reconnected frequently enough to allow a battery-powered device to work with the power module 100 is not completely discharging internal batteries during a period of no power at the input to the connected device. After the power output 120 is reconnected, tests or evaluates the power module circuit 130 in one exemplary embodiment, load conditions, such as the power output on the power output 120 , otherwise. If the load condition at the power output 120 is increased above the previously measured value, the power output remains 120 with the primary circuit of the current transformer 231 until the load state has returned to a selected or predetermined threshold indicative of a "low load". If the power requirement at the power output 120 In other words, power to the power output increases 120 delivered until the power requirement drops and indicates a defined idle mode. In an exemplary embodiment, the determination of load conditions at the reconnect is made after a selected period of time has elapsed, for example after a number of seconds or minutes, such that start-up or initialization events are ignored. In another embodiment, the load conditions may be averaged over a selected time period of a few seconds or minutes so that short bursts of high load cancel out on average. In yet another exemplary embodiment, the power module 100 a master reconnect device, all power outputs 120 again with the power input 110 can couple.

In an exemplary operating method, the switch 233 of the power module 100 closed at an initial power up, giving power to the power output 120 flows. When load conditions at the power output 120 are below a threshold, the control circuit opens 232 the switch 233 to generate an open circuit and the power output 120 decoupling from the input power signal. This decoupling effectively eliminates idle power caused by the power output 120 get lost. In one embodiment, the threshold is a predetermined value, for example, approximately one watt of power or less, that is related to the power output 120 flows.

In an exemplary embodiment, different power outputs 120 have different, fixed thresholds such that devices with a higher idle power value for power management are useful with the power module 100 can be connected. For example, a large device may still draw about 5 watts during idle, but would never draw from the power output 110 disconnected if the connected power output 120 would have a threshold of about 1 watt. In various embodiments, certain power outputs 120 higher threshold to accommodate high-performance devices or lower-threshold devices for lower performance.

In another embodiment, the threshold is a learned value. The learned value can be determined by long-term monitoring of load conditions on the power output 120 through the control circuit 232 be set up. Over time, monitoring creates a history of performance values and can serve as a template for power demand. In an exemplary embodiment, the control circuit examines 232 the history of performance values and decides whether long time periods of low power demand were times one with the power output 120 connected device was in a low or lowest power mode. In an exemplary embodiment, the control circuit couples 232 the power output 120 during periods of low power usage, when the low power period of time matches the template. For example, the template might show that the device is going through the power output 120 power for eight hours followed by sixteen hours of low power.

In another exemplary embodiment, the control circuit determines 232 the approximate low power value of the electronic device connected to the power output 120 is connected and sets a threshold to a percentage of the determined approximate low power value. For example, the control circuit 232 set the threshold to approximately 100-105% of the approximate low power value requirement. In another embodiment, the threshold demand may be set to about 100-110% or 110-120% or more of the approximate low power requirement. In addition, the percentile range of the low power value may be any variation or combination of the disclosed ranges.

In addition, the learned threshold can be adjusted manually. In accordance with an exemplary embodiment, a threshold value is partially established by activating the reconnect device 234 for a period of time and measuring a current power value. For example, a user may use the reconnect device 234 Hold off for a few seconds when the power module 100 in idle mode, and measure the power value. The measured power value is used to set the power threshold. In an exemplary embodiment, the threshold is set to a measured power value plus an offset value. The offset value can be configured at different power levels. Further, the offset value may be increased or decreased as appropriate for a particular configuration. For example, if the measured threshold is about 1 W and an offset value of about 0.5 W is used, then the threshold is about 1.5 W. In one exemplary embodiment, the power module is 100 designed to operate in an ultra-low idle mode if the load falls below about 1.5W in this example. Conveniently, the threshold can be more accurately adjusted by manually initiating a power measurement.

Having disclosed various functions and structures for an exemplary power module configured to reduce or eliminate power during an idle mode by decoupling the power input, a detailed circuit diagram of an exemplary power module may be provided 400 according to an exemplary embodiment of the present invention. With reference to 4 In an exemplary embodiment of the power module, FIG 400 the power module circuit 130 the current transformer 231 , the current sensor 301 , the logic control unit 302 , the power disconnection 303 , the reconnect memory state 304 and the switch 233 on.

In one embodiment, the current transformer act 231 and the current sensor 301 together to get the power from the power input 110 and to convert the current into a proportional DC voltage provided by the logic controller 302 can be read. Furthermore, the switch 233 a latch relay, such as a relay coil K1, which is in response to a command from the logic controller 302 a hard connection / disconnection of the power input 100 regarding the power output 120 supplies. The desk 233 Switches between an open and a closed contact. Further, the switch stops 233 its position until reset by the logic controller 302 and holds its position so that in a relay coil K1 no power is consumed.

In an exemplary embodiment, the logic controller 302 a microcontroller or microcontroller receiving an input of the current in the power input line, the state of the switch 233 controls and the state or position of the reconnection device 234 and the switch 233 read or otherwise rated. In addition, the logic control unit learns and stores 302 the performance profile for an electronic device that matches the power output 120 connected is. In another exemplary embodiment, the power module circuit 130 Further, the reconnecting device 234 and the reconnect memory state 304 on. The reconnecting device 234 is activated to the power output 120 turn on when the power module circuit 130 for the first time with the receipt of power 110 is connected or if full power directly at the power output 120 is needed. The reconnect memory state 304 is designed to be the logic control unit 302 indicate whether the reconnecting device 234 was activated lately.

In an exemplary embodiment, the power disconnect 303 a network of transistors Q1, Q2, Q3 used in conjunction with Zener diodes Z1, Z2 to sense the power input 110 to condition to a safe value for the logic controller 302 is suitable, and the logic control unit 302 from the power input 110 to separate. In another embodiment, the power disconnect 303 in addition to the transistors of the previous embodiment, or instead of the same, relay on.

The initial connection of the power module 400 relates to connecting the power module 400 with a power source that can be AC or DC. In an exemplary method, initial plugging in the power module 400 to a power source all circuits of the power module circuit 130 energized or de-energized and is the switch 233 in the last position or the last state by the logic control unit 302 was set. This initial state may be power to the power output 120 deliver or not. When all circuits are de-energized, current does not flow into the power module circuitry 130 , This is due to the separation or electrical insulation caused by the power separation 303 and the reconnecting device 234 delivered in a normal, open position. In an exemplary embodiment, the power disconnect 303 the transistors Q1, Q2, Q3 and a capacitor C3. In this condition, only leakage current flows through the transistors Q1, Q2 and the leakage current will be on the order of approximately tens of nanoamps. Furthermore, the current transformer supplies 231 a dielectric isolation from the primary side to the secondary side, so that due to the Zwischenwicklungskapazität of the current transformer 231 only a little leakage current flows.

With further reference to 4 In an exemplary embodiment and for illustrative purposes, a user may implement the circuit using the reconnect device 234 reconnect to a current path through a diode D1, Zener diode Z1, the reconnect device 234 to produce a resistor R4, a diode D6 and the zener diode Z3. Diode D1 serves to half-wave rectify the AC line to reduce the peak voltage by half. Zener diode Z1 further reduces the voltage from diode D1, for example to about 20 volts. Zener diode Z3 and resistor R4 form a current limited Zener regulator that provides a suitable DC voltage at the VDD input to the logic controller 302 supplies while the reconnecting device 234 is held. In addition, a capacitor C2 smoothes the DC signal on the zener diode Z3 and provides the reconnection device during the contact jump 234 for storage. Capacitor C2 is sized to operate during the logic controller on time 302 to provide sufficient storage, and capacitor C2, in combination with resistor R4, provides a fast rising edge at the VDD input to the logic controller 302 reset properly. Further, a diode D5 separates the capacitor C2 from a capacitor CS so that the rise time constant of the capacitor C2 and the resistor R4 is not affected by the large capacitance of the capacitor CS. When the capacitor CS is the logic control unit 202 supplied with power, the current of the capacitor CS passes through the diode D5. The diode D6 serves to disconnect the voltage across the capacitor C2 when the reconnecting device 234 is released. This allows the voltage to be maintained during the closed state duration of the reconnect device 234 is stored on the capacitor C5 is held when the Wiederverbindungsvorrichtung 234 is in the open state, and the logic controller 302 informed about the opened state.

If the reconnecting device 234 is enabled for a few milliseconds, so in an exemplary method is the logic controller 302 designed to initialize the deployment of their own power and set it up immediately before the reconnecting device 234 is released. This is done by voltage doubler outputs VD1-VD3 and ZG of the logic controller 302 achieved. First, the output ZG1 is driven high to turn on the transistor Q2. When transistor Q2 is turned on, a current path is established through resistor R3 and zener diode Z2, which provides a regulated voltage at the drain of transistor Q1. This regulated voltage is similar to that produced by Zener diode Z3 and is for the VDD input of the logic controller 302 suitable. Secondly, after the voltage on the Zener diode Z2 has stabilized for a few microseconds, the outputs VD1-VD3 of the logic controller begin 302 to generate a gate drive signal to turn on transistor Q1. The signals passing through the outputs VD1-VD3 and components including the capacitor C3, the transistor Q3, the Capacitor C4, diode D3 and diode D4, generate a voltage at the gate of transistor Q1 that is approximately twice the voltage at the input VDD of the logic controller 302 is. This voltage doubling turns on transistor Q1 hard. When the transistor Q1 is turned on, the voltage on the Zener diode Z2 charges the capacitor CS. In an exemplary embodiment, capacitor CS is a large storage capacitor used to power the logic controller 302 to power when the reconnecting device 234 is not activated. After the capacitor CS has been charged for a few milliseconds, the outputs VD1-VD3 and ZG1 return to an idle state and the transistors Q1 and Q2 are turned off. In this embodiment, the logic controller is 302 based on the charge stored in the capacitor CS and does not draw power from the power input 110 , When the reconnecting device 234 is no longer active, the capacitor CS supplies the logic control unit 302 continue with performance.

If the power output 120 is idle and draws substantially no power is the logic controller 302 may be able to decouple from pulling power and entering a "sleep" mode or sleep mode. In an exemplary method and with further reference to 4 is when the logic controller 302 is effective on the basis of the stored energy in the capacitor CS, in the logic control unit 302 enabled a timing function that uses the capacitor C6 to perform the timing function. The capacitor C6 is passed through the CAPTIME output of the logic controller 302 briefly charged, and over time, the discharge rate of the capacitor C6 mimics the decay of the voltage across the capacitor CS. When the voltage of the capacitor C6 at the input CAPTIME reaches a low value, the logic control unit stops 302 the state of the outputs VD1-VD3 and ZG1 to recharge the capacitor CS from the AC line again. This process is repeated again and again, so that for the logic control unit 302 Never loses power. Depending on the size of the capacitor CS, execution of the recharging process takes only a few milliseconds or less.

Further, in an exemplary method, when the logic controller 302 is not busy recharging the capacitor CS, switching the relay K1 or the power output 120 to measure drawn power, the logic control unit 302 in a deep sleep mode, which stops all or substantially all of the internal activity and waits for the capacitor C6 to discharge. This sleep mode consumes very little power and allows the charge on the storage capacitor CS to persist for many seconds. If the reconnecting device 234 is activated during sleep mode, the capacitor is recharged and takes the logic controller 302 normal operation again and sets the relay K1 or resets the same. Alternatively, if the voltage of the capacitor C6 becomes too low, the logic controller will charge 302 the capacitor CS again and then returns to sleep mode.

While an electronic device is in an idle mode, the power module may 100 continue to monitor for changes in performance being pulled through the electronic device. While the logic controller 302 continually entering and exiting the idle mode to power itself up again tests the logic controller in an exemplary method 302 Also regularly the power of the power output 120 is pulled. The duration of the performance test is much greater than that of the charging of the capacitor CS, and the test may be done for example only every ten minutes or more. According to an exemplary method, there are at least three possible outcomes from the result of the performance test: 1) the device is in operation and the switch is not in the standby state, 2) the device is not in operation, but the switch is not in one Standby state, or 3) the switch is in a ready state. For the result, when the device is in operation and the switch is not in a standby state, the relay K1 has been previously set to output power to the output 120 and the performance test shows that a significant load current is being drawn through the connected electronic device. A "significant load" may be defined by a particular fixed value when the logic controller 302 or may be the result of a number of performance tests and may be the typical load current for that electronic device. A performance test result is interpreted here as normal states and the logic control unit 302 returns to a periodic pass through the sleep mode until another time period, such as ten minutes, has elapsed, when the performance test is again performed. In another exemplary embodiment, the duration of the periodic sweep of the sleep mode is determined by a user. For example, a user may set the duration of the sleep mode to one, two, or five minutes using a dialer, a digital input, a push button, a keypad or any other suitable device currently known or subsequently developed.

For the result, when the device is not in operation, but the switch is not in a standby state, the relay K1 has been previously set to output power to the output 120 and the performance test shows that a negligible load current is being drawn through the connected equipment. The "negligible load" may be a certain fixed value that enters the logic controller 302 or may be the result of a number of performance tests, and may be the typical minimum found for that electronic device. In any case, the action is performed by the logic control unit 302 is made, the relay K1 using the outputs RELAY1-RELAY2 the logic controller 302 in an open state to energize the relay coil K1. The state of the relay K1 is through the logic control unit 302 which checks for the presence of a resistor R5 on RELAY3 since the logic controller 302 possibly does not know the previous state of the relay K1, for example, starting from a disconnected state.

For the result, when the switch is in a standby state, that is, the relay K1 has been set to output power from the power output 120 to remove, the logic control unit must 302 K1 into a closed state to allow AC power to be applied to the power output. In an exemplary method, once relay K1 is set, a period of time may pass before the performance test is made. This delay allows the electronic device connected to the power output 120 is connected, can initialize and enter a stable operating mode. Now, power measurements can be taken over a certain period of time to determine if the electronic device is in a lower or high power state. If a high power condition is determined, relay K1 remains set. If a low power condition is determined, the relay K1 is reset to an open state and becomes power again from the power output 120 away. Also starts the logic controller 302 after a certain period of time, for example every ten minutes, again with the cyclic execution of the idle mode and with the performance test.

If a user wants to operate a device with the power output 120 is connected, and this power output is turned off, in one exemplary embodiment activating the reconnection device 234 the logic controller 302 immediately wake from sleep mode. Because the awakening of the activation of the reconnecting device 234 and is not due to the performance test or the recharging of the capacitor CS, the logic control unit offsets 302 The relay K1 immediately into a closed state to the electronic device that is connected to the power output 120 connected to provide power.

In addition to the embodiments described above, various other elements may be implemented to enhance control and user experience. One way to improve control for the user is to allow a user to select the operating mode of a power output. In an exemplary embodiment, the power module has 100 a switch for a "green mode", which activates or deactivates the "green" mode of operation. The green or environmentally friendly switch may be a hard, manual switch, or it may be a signal to the logic controller 302 act. Operation in the "green" mode consists in disconnecting the power output 120 from the power input 110 when there is essentially no load on the power output 120 is pulled. A user may use the green mode switch to disable green mode operation on various power outputs, if desired. For example, this additional control may be desirable at power outputs that power devices with clocks or devices that need to be turned on instantly, such as a fax machine.

The power module 100 In one embodiment, includes LED indicators that may indicate whether a power output is connected to the power line and is drawing a load current. The LED indicators may indicate whether a power output is active, that is, power is drawn by an electronic device and / or the power output has power, even when no electronic device is connected. In addition, a pulsating LED can be used to show when a performance test is being made or to indicate the "heartbeat" of a recharge in sleep mode.

In a further embodiment, the power module 100 at least one LCD display. The LCD display can be controlled by the logic controller 302 operated to indicate the load power connected to the power output 120 is delivered, for example during periods of operation. The LCD can also provide information about operating or not using the power module 100 deliver power saved or power consumed in a "green" mode. For example, the LCD may display the total amount of watts saved during a particular period of time, such as the lifetime of the power module 100 or in one day.

Various embodiments may also be used to enhance the efficient use of the power module and / or individual power outputs in the power module. One such embodiment is an implementation of a photocell or other optical sensor provided by the logic controller 302 is monitored. The photocell determines if light is at the position of the power module 100 is present, and the logic controller 302 can use this determination to the power output 120 decouple depending on the ambient light conditions. For example, the logic controller 302 the power output 120 decouple during dark periods of time. In other words, the power outputs of the power module can be turned off at night. Another example is devices that do not require power when positioned in a dark room, such as an unused conference room in an office. Also, the power outputs may be turned off when the ambient light conditions exceed a certain value, which may be predetermined or determined by a user.

In a further embodiment, the power module 100 also an internal clock. The logic controller 302 can use the internal clock to learn at what time periods high power usage at the power output 120 shows. This insight may be included in a determination of when a power output should have power available. In an exemplary embodiment, the internal clock has the accuracy of a quartz crystal. Also, the internal clock need not be set to an actual time. Furthermore, the internal clock in combination with the photocell can be used for greater efficiency and / or accuracy of the power module.

The current transformer 631 provides an output power signal that is proportional to the load on the outlet 520 is. Further, the switch provides 633 a connection between the primary circuit of the current transformer 631 and the outlet 520 ago.

In an exemplary embodiment, the control circuit 632 at least one or a combination of the following: a latch circuit, an analog circuit, a state machine and a microprocessor. In one embodiment, the control circuit monitors 632 the state of the secondary winding of the current transformer 631 and controls the operation of the switch 633 , In an exemplary embodiment, the control circuit further receives 632 a low frequency or DC signal from the current transformer 631 , The low-frequency signal may have, for example, 60 Hz. This low frequency or DC signal is provided by the control circuit 632 interpreted as the current caused by the load on the socket 520 is needed.

The control circuit 632 may have various structures for monitoring the state of the secondary winding of the current transformer 631 and for controlling the operation of the switch 633 exhibit. In an exemplary embodiment, and with reference to 7 , includes the control circuit 632 a current sensor 701 and a logic controller 702 , The current sensor 701 monitors the output of a current measuring system, such as the secondary winding of the current transformer 631 , which is an AC voltage that is proportional to the load current. Further, the current sensor provides 701 a signal to the logic controller 702 , In one embodiment, the signal may be a DC voltage that is proportional to the current flowing through the current sensor 701 is monitored. In another embodiment, the signal may be a current that is proportional to the current flowing through the current sensor 701 is monitored. In another exemplary embodiment, as well as by currently referring to 8th , indicates the wall plate circuit 530 the wallplate system a logic controller 702 on that with more than one current transformer 631 and more than a switch 633 communicates and controls the same.

In an exemplary embodiment, the logic controller is 702 powered by an energy storage capacitor. The logic controller 702 may briefly connect to the storage capacitor to supply power to the logic controller 702 continue. In another embodiment, the logic controller 702 be powered by a battery or other power source. This energy source is also referred to as household or hotel services; it acts as a source of low auxiliary power. In one embodiment, auxiliary power is sourced from the AC line input 510 taken. For further details on similar current monitoring, see U.S. Provisional Patent Application 61 / 052,939 entitled "Circuit and Method for Ultra-Low Noble Power".

In an exemplary embodiment, the logic controller is one 702 to a microprocessor before and after integration of the wall plate system 500 is programmable in an electronic device. In one embodiment, a user may connect to the logic controller 702 produce and the parameters of the wall plate system 500 Customize. For example, a user may set the threshold and a sleep mode duty cycle of the wallplate system 500 to adjust. For example, data could be from past power consumption and / or energy from the wallplate system 500 be transmitted. The bidirectional data transfer between the wall plate system 500 and a display device may be achieved by a wireless signal, such as an infrared signal, a radio frequency signal, or other similar signal. The data transmission can also be accomplished using a wired connection, such as for example, a USB connection or other similar connection.

According to an exemplary embodiment, the control circuit 632 also a power separation 703 having the logic control unit 702 communicates. The power separation 703 is designed to be the logic control unit 702 from the AC line input 510 to separate or electrically isolate and reduce power loss. While the logic controller 702 is disconnected, it is powered by the storage capacitor or other power source and the logic controller 702 enters a sleep mode. If the storage capacitor reaches a low power level, the power disconnect is 703 designed to be the logic control unit 702 again with the AC line input 510 to reconnect to recharge the storage capacitor. In an exemplary embodiment, the power disconnect is 703 able to reduce the power loss from a leakage current in the microampere range to a leakage current in the nanoampere range.

In another exemplary embodiment, the control circuit receives 632 a control signal corresponding to the AC line input 510 is impressed by another controller. The control signal may be, for example, the X10 control protocol or other similar protocol. The control circuit 632 can the control signal through the secondary winding of the current transformer 631 , from a paired AC line input 510 or any other suitable device currently known or subsequently developed that is configured to accept the AC line input 510 with the control circuit 632 to pair. This control signal may be from within the wallplate system 600 come from or may come from an external controller. The control signal may be a high frequency control signal or at least a control signal having a frequency different from the frequency of the AC line input 510 different. In an exemplary embodiment, the control circuit interprets 632 the high-frequency control signal to the switch 633 switch on or off. In another embodiment, an external controller may transmit a signal to the wallplate system 600 into an "on" or "off" state.

In an exemplary embodiment, if a behavior of the secondary winding of the current transformer 631 indicates that the outlet 520 essentially no power from the AC line input 510 pull, enable or control the switch 633 the decoupling of the primary circuit of the current transformer 631 from the socket 520 , In other words, the switch allows 633 Disconnecting a power source from the outlet 520 , In an exemplary embodiment, the secondary winding of the current transformer 631 monitored on an AC waveform with the AC line frequency, wherein the AC waveform has an RMS voltage that is proportional to the load current passing through the primary circuit of the current transformer 631 to the socket 520 flows. In another embodiment, the AC waveform is rectified and filtered to prevent it from being received by the control circuit 632 to generate a DC signal. The DC signal is proportional to the load current passing through the primary circuit of the current transformer 631 to the socket 520 flows.

In one embodiment, the phrase "substantially no power" is intended to mean that the output power is in the range of approximately 0-1% of a typical maximum output load. In an exemplary embodiment, the switch 633 designed to connect the primary circuit of the current transformer 631 with the socket 520 to control, and has a switching mechanism to the primary circuit of the current transformer 631 essentially from the outlet 520 decouple. The desk 633 may include a relay, a latch relay, a TRIAC and an optically isolated TRIAC or other disengaging circuitry.

By the primary circuit of the current transformer 631 is essentially disabled or disabled, can be the power consumption at the outlet 520 reduce. In one embodiment, the outlet 520 essentially to lock out mean that the output signal of the secondary winding of the current transformer 631 through the control circuit 632 was interpreted as sufficiently low, so it is appropriate to the switch 633 Uncouple and power from the outlet 520 to remove.

In another exemplary embodiment, the wall plate circuit 530 Further, a reconnecting device 634 formed to close the switch 633 through the logic controller 702 to enable. Closing the switch 633 connects the socket 520 again with the primary circuit of the current transformer 631 and the AC line input 510 , In an exemplary embodiment, the reconnect device 634 a switching device which can be closed and opened in various ways. For example, the reconnecting device 634 have a push button that can be operated manually. In one embodiment, the push button on the front of the Wall panel system 500 positioned. In another embodiment, the reconnecting device 634 through itself through the AC line input 510 moving signals representing the control circuit 632 interpreted as an on / off control, remotely influenced. In yet another embodiment, the reconnecting device 634 controlled by a wireless signal, such as an infrared signal, a radio frequency signal or other similar signal.

According to another exemplary embodiment, the switch 633 automatically operated on a regular basis. For example, the switch 633 automatically reconnect after a few minutes or tens of minutes, or any more or less frequent period of time. In one embodiment, the switch 633 Automatically reconnected frequently enough to allow a battery-powered device to work with the wall plate system 500 is not completely discharging internal batteries during a period of no power at the input to the connected device. After the socket 520 is reconnected, checks or evaluates the wall plate circuit 630 in an exemplary embodiment, load conditions, such as power requirements at the outlet 520 otherwise. If the load condition at the socket 520 above the previously measured value, the socket remains 520 with the primary circuit of the current transformer 631 until the load state has returned to a selected or predetermined threshold indicative of a "low load". If the power requirement at the socket 520 In other words, power is increased to that of the power outlet 520 delivered until the power requirement drops and indicates a defined idle mode. In an exemplary embodiment, the determination of load conditions at the reconnect is made after a selected period of time has elapsed, for example after a number of seconds or minutes, such that start-up or initialization events are ignored. In another embodiment, the load conditions may be averaged over a selected time period of a few seconds or minutes so that short bursts of high load cancel out on average. In yet another exemplary embodiment, the wallplate system 500 a master reconnect device, all sockets 520 again with the AC line input 510 can couple.

In an exemplary operating method, the switch 633 the wall plate system 500 closed at initial startup, allowing power to the outlet 520 flows. When load conditions at the outlet 520 are below a threshold, the control circuit opens 632 the switch 633 to create an open circuit and the power outlet 520 decouple from the AC power signal. This decoupling effectively eliminates idle power coming through the socket 520 get lost. In one embodiment, the threshold is a predetermined value, for example, approximately one watt of power or less, to the outlet 520 flows.

In an exemplary embodiment, different sockets 520 have different, fixed thresholds so that higher power idle devices for power management will be useful with the wallplate system 500 can be connected. For example, a large device may still draw about 5 watts during idle, but would never pull from the AC power input 510 disconnected if the connected sockets 520 would have a threshold of about 1 watt. In various embodiments, certain sockets 520 higher threshold to accommodate high-performance devices or lower-threshold devices for lower performance.

In another embodiment, the threshold is a learned value. The learned value can be determined by long-term monitoring of load conditions at the socket 520 through the control circuit 632 be set up. Over time, monitoring creates a history of performance values and can serve as a template of performance needs. In an exemplary embodiment, the control circuit examines 632 the history of performance values and decides whether long time periods of low power demand were times, as with the power outlet 520 connected device was in a low or lowest power mode. In an exemplary embodiment, the control circuit couples 632 the socket 520 during periods of low power usage, when the low power period of time matches the template. For example, the template might show that the device is plugged in 520 power for eight hours followed by 16 hours of low power consumption.

In another exemplary embodiment, the control circuit determines 632 the approximate low power rating of the electronic device that is plugged in 520 is connected and sets a threshold to a percentage of the determined approximate low power value. For example, the control circuit 632 the threshold to about 100-105% of the approximate low power value requirement. In another embodiment, the threshold demand may be set to about 100-110% or 110-120% or more of the approximate low power requirement. In addition, the percentile range of the low power value may be any variation or combination of the disclosed ranges.

In addition, the learned threshold can be adjusted manually. In accordance with an exemplary embodiment, a threshold value is partially established by activating the reconnect device 634 for a period of time and measuring a current power value. For example, a user may use the reconnect device 634 Hold off for a few seconds when the wall plate system 500 in idle mode, and measure the power value. The measured power value is used to set the power threshold. In an exemplary embodiment, the threshold is set to a measured power value plus an offset value. The offset value can be configured at different power levels. Further, the offset value may be increased or decreased as appropriate for a particular configuration. For example, if the measured threshold is about 1 W and an offset value of about 0.5 W is used, then the threshold is about 1.5 W. In an exemplary embodiment, the wall plate system is 500 designed to operate in an ultra-low idle mode if the load falls below about 1.5W in this example. Conveniently, the threshold can be more accurately adjusted by manually initiating a power measurement.

Having disclosed various functions and structures for an exemplary wall panel system configured to reduce or eliminate power during an idle mode by decoupling the power input, a detailed circuit diagram of an exemplary wall panel system may be provided in accordance with an exemplary embodiment of the present invention. With reference to 9 In an exemplary embodiment, FIG. 10 shows a wall plate system 900 the wall plate circuit 530 , the current transformer 631 , the current sensor 701 , the logic control unit 702 , the power disconnection 703 and the switch 633 on.

In one embodiment, the current transformer act 631 and the current sensor 701 to measure the current in the AC line input and to convert the current into a proportional DC voltage supplied by the logic controller 702 can be read. Furthermore, the switch 633 have a latching relay, which after a command from the logic control unit 702 a hard connection / disconnection of the AC line input 510 regarding the socket 520 supplies. The desk 633 Switches between an open and a closed contact. Further, the switch stops 633 its position until reset by the logic controller 702 and holds its position so that in a relay coil K1 no power is consumed.

In an exemplary embodiment, and similar to the logic controller 302 , instructs the logic controller 702 a microcontroller or microcontroller receiving an input of the current in the AC line, the state of the switch 633 controls and the state or position of the reconnection device 634 and the switch 633 read or otherwise rated. In addition, the logic control unit learns and stores 702 the performance profile for an electronic device connected to the power outlet 520 connected is. In another exemplary embodiment, the wall plate circuit 530 Further, the reconnecting device 634 on, which is activated to the power outlet 520 turn on when the wall plate circuit 530 for the first time with the AC power input 510 is connected or when a full power directly from the outlet 520 is needed.

In an exemplary embodiment, the power disconnect 703 a network of transistors Q1, Q2, Q3 used to connect the AC line 510 to condition to a safe value for the logic controller 702 is appropriate, and to the logic controller 702 from the AC line input 510 to separate. In another embodiment, the power disconnect 703 in addition to the transistors of the previous embodiment, or instead of the same, relay on.

The initial connection of the wall plate system 900 relates to a connection of the wall plate system 900 with an AC power source. In an exemplary method, initial insertion of the wallplate system 900 to a power source all the circuits of the wall plate circuit 530 energized or de-energized and is the switch 633 in the last position, by the logic control unit 702 was determined. This initial condition may be power to the outlet 520 deliver or not. When all circuits are de-energized, current does not flow into the wall plate circuit 530 , This is due to the separation or electrical insulation caused by the power separation 703 and the reconnecting device 634 delivered in a normal, open position. In an exemplary embodiment the power separation 703 the transistors Q1, Q2, Q3 and a capacitor C3. In this condition, only leakage current flows through the transistors Q1, Q2 and the leakage current will be on the order of approximately tens of nanoamps. Furthermore, the current transformer supplies 631 a dielectric isolation from the primary side to the secondary side, so that due to the Zwischenwicklungskapazität of the current transformer 631 only a little leakage current flows.

With further reference to 9 In an exemplary embodiment and for illustrative purposes, a user may implement the circuit using the reconnect device 634 reconnect to a current path through a diode D1, a Zener diode Z1, a resistor R4, the reconnect device 634 and produce a zener diode Z3. Diode D1 serves to half-wave rectify the AC line to reduce the peak voltage by half. Zener diode Z1 further reduces the voltage from diode D1, for example to about 20 volts. Zener diode Z3 and resistor R4 form a current limited Zener regulator that provides a suitable DC voltage at the VDD input to the logic controller 702 supplies while the reconnecting device 634 is held. In addition, a capacitor C2 smoothes the DC signal on the zener diode Z3 and provides the reconnection device during the contact jump 634 for storage. Capacitor C2 is sized to operate during the logic controller on time 702 to provide sufficient storage, and capacitor C2, in combination with resistor R4, provides a fast rising edge at the VDD input to the logic controller 702 reset properly. Further, a diode D5 separates the capacitor C2 from a capacitor CS so that the rise time constant of the capacitor C2 and the resistor R4 is not affected by the large capacitance of the capacitor CS. When the capacitor CS is the logic control unit 202 supplied with power, the current of the capacitor CS passes through the diode D5.

If the reconnecting device 634 is activated for a few milliseconds, so in an exemplary method is the logic controller 702 designed to initialize the deployment of their own power and set it up immediately before the reconnecting device 634 is released. This is done by voltage doubler outputs VD1-VD3 and an output ZG1 of the logic controller 702 achieved, similar to the reconnection process, which the logic controller 302 assigned. If the outlet 520 is idle and draws substantially no power is the logic controller 702 may be able to decouple from pulling power and entering a "sleep" mode or sleep mode. In an exemplary method and with further reference to 9 is when the logic controller 702 is effective on the basis of the energy stored in the capacitor CS, one in the logic control unit 302 Timing function that uses the capacitor C5 to perform the timing function. Capacitor C5 is passed through the CAPTIME output of the logic controller 702 briefly charged, and over time, the discharge rate of the capacitor C5 mimics the decay of the voltage across the capacitor CS. When the voltage of the capacitor C5 at the input CAPTIME reaches a low value, the logic control unit stops 702 the state of the outputs VD1-VD3 and the output ZG1, to recharge the capacitor CS from the AC line again. This process is repeated again and again, so that for the logic control unit 702 Never loses power. Depending on the size of the capacitor CS, execution of the recharging process takes only a few milliseconds or less.

Further, in an exemplary method, when the logic controller 702 is not busy recharging the capacitor CS to switch the relay K1 or from the socket 520 to measure drawn power, the logic control unit 702 in a deep sleep mode that stops all or substantially all of the internal activity and waits for the capacitor C5 to discharge. This sleep mode consumes very little power and allows the charge on the storage capacitor CS to persist for many seconds. If the reconnecting device 634 is activated during sleep mode, the logic controller takes 702 normal operation again and sets the relay K1 or resets the same. Alternatively, if the voltage of the capacitor C5 becomes too low, the logic controller will charge 702 the capacitor CS again and then returns to sleep mode.

For example, the LCD may display the total amount of watts saved during a particular period of time, such as the life of the wallplate system 500 or in one day.

Various embodiments may also be used to enhance the efficient use of the wallplate system and / or individual sockets in the wallplate system. One such embodiment is an implementation of a photocell or other optical sensor provided by the logic controller 702 is monitored. The photocell determines if light is in the position of the wall plate system 500 is present, and the logic controller 702 can use this provision to the outlet 520 decouple depending on the ambient light conditions. For example, the logic controller 702 the socket 520 decouple during dark periods of time. In other words, the sockets of the wall plate system can be turned off at night. Another example is devices that do not require power when positioned in a dark room, such as an unused conference room in an office. Also, the outlets may be turned off when the ambient light conditions exceed a certain value that may be predetermined or determined by a user.

In a further embodiment, the wall plate system 500 also an internal clock. The logic controller 702 can use the internal clock to learn at what time periods high power usage at the outlet 520 shows. This insight can be included in a determination of when a power outlet should have power available. In an exemplary embodiment, the internal clock has the accuracy of a quartz crystal. Also, the internal clock need not be set to an actual time. Furthermore, the internal clock for greater efficiency and / or accuracy of the Wall plate system can be used in combination with the photocell.

In one embodiment, the threshold is a predetermined value, for example, approximately one watt of power or less, to the outlet 1120 flows.

In an exemplary embodiment, different sockets 1120 have different fixed thresholds, so that devices with a higher power value in the Idle for power management in a useful way with the multiple socket 1100 can be connected. For example, a large device may still draw about 5 watts during idle, but would never pull from the AC power input 1110 disconnected if the connected sockets 1120 would have a threshold of about 1 watt. In various embodiments, certain sockets 1120 higher threshold to accommodate high-performance devices or lower-threshold devices for lower performance. In another embodiment, the threshold is a learned value. The learned value can be determined by long-term monitoring of load conditions at the socket 1120 through the control circuit 1232 be set up. Over time, the monitoring generates a history of performance values and can serve as a template for power demand. In an exemplary embodiment, the control circuit examines 1232 the history of performance values and decides whether long time periods of low power demand were times, as one with the power outlet 1120 connected device was in a low or lowest power mode. In an exemplary embodiment, the control circuit couples 1232 the socket 1120 during periods of low power usage, when the low power period of time matches the template. For example, the template might show that the device is plugged in 1120 power for eight hours followed by 16 hours of low power consumption.

In another exemplary embodiment, the control circuit determines 1232 the approximate low power rating of the electronic device that is plugged in 1120 is connected and sets a threshold to a percentage of the determined approximate low power value. For example, the control circuit 1232 set the threshold to approximately 100-105% of the approximate low power value requirement. In another embodiment, the threshold demand may be set to about 100-110% or 110-120% or more of the approximate low power requirement. In addition, the percentile range of the low power value may be any variation or combination of the disclosed ranges.

In addition, the learned threshold can be adjusted manually. In accordance with an exemplary embodiment, a threshold value is partially established by activating the reconnect device 1234 for a period of time and measuring a current power value. For example, a user may use the reconnect device 1234 Keep it off for a few seconds when the power strip is removed 1100 in idle mode, and measure the power value. The measured power value is used to set the power threshold. In an exemplary embodiment, the threshold is set to a measured power value plus an offset value. The offset value can be configured at different power levels. Further, the offset value may be increased or decreased as appropriate for a particular configuration. For example, if the measured threshold is about 1 W and an offset value of about 0.5 W is used, then the threshold is about 1.5 W. In an exemplary embodiment, the multiple socket is 1100 designed to operate in an ultra-low idle mode if the load falls below about 1.5W in this example. Conveniently, the threshold can be more accurately adjusted by manually initiating a power measurement.
