FIG. 1 depicts a front cut-away view of a power drop assembly. Power drop assembly 100 includes power cord housing 102, reel 104, power cord 106, female power outlet 108, electrical input 110, switching circuitry 112, and controller 114. Reel 104 is positioned within and rotatably connected to power cord housing 102. Power cord 106 is mechanically attached to reel 104. Female power outlet 108 is mechanically and electrically attached to power cord 106. Switching circuitry 112 is electrically connected to electrical input 110. Switching circuitry 112 selectively, electrically connects electrical input 110 and power cord 106. Switching circuitry 112 is also electrically connected to power cord 106. Controller 114 is communicatively connected to switching circuitry 112 for controlling switching circuitry 112.
Electrical input 110 is electrically connected to switching circuitry 112 wirelessly or via wiring 116. Electrical input 110 and switching circuitry 112 each include wireless power transfer coils for inductive coupling of electrical input 110 and switching circuitry 112.
Power cord 106 is electrically connected to switching circuitry 112 via wiring 118. Switching circuitry 112 is communicatively connected to controller 114 wirelessly or via wire 120. Wiring 118 is connected with power cord 106 via a rotating electrical connector.
Electrical input 110 is electrically connected to a power source such as a power outlet. Instructions are sent from controller 114 to switching circuitry 112. Switching circuitry 112 subsequently allows or disallows electrical current to flow through electrical input 110 to power cord 106. An electrical device is electrically connected to female power outlet 108. While switching circuitry 112 allows current flow through power cord 106, the electrical device draws power from power cord 106 through female power outlet 108.
Controller 114 includes calendar instructions to send instructions to switching circuitry 112, to either allow or disallow current flow through power cord 106, according to hourly, daily, weekly, monthly, or yearly calendar instructions. For example, controller 114 includes calendar instructions which cause controller 114 to send instructions to switching circuitry 112 such that switching circuitry 112 allows current flow through power cord 106 during a first set of hours of day. Controller 114 also includes calendar instructions which cause controller 114 to send instructions to switching circuitry 112 such that switching circuitry 112 disallows current flow through power cord 106 during a second set of hours of day.
Reel 104 is rotatably connected to power cord housing 102 with any of a variety of means, including ball bearing(s), roller bearing(s), or journal bearing(s).
FIG. 2 depicts an embodiment similar to FIG. 1 with power throttling circuitry. Power drop assembly 200 further includes power throttling circuitry 220. Power throttling circuitry 220 is electrically connected to power cord 206. Power throttling circuitry 220 allows variable amounts of power to be consumed via power cord 206. For example, current passing through power throttling circuitry 220 begins to exceed a preset current threshold. Power throttling circuitry 220 limits current passing through power throttling circuitry 220 to below or at the preset current threshold.
Controller 214 is communicatively connected to power throttling circuitry. For example, controller 214 sends instructions to power throttling circuitry 220 and power throttling circuitry 220 limits an amount of current flow across power throttling circuitry 220 in accordance with the instructions sent by controller 214. Controller 214 receives current flow data from power throttling circuitry 220. Controller 214 instructs power throttling circuitry 220 to limit current flow based on any of a number of criteria, including time of day, time of week, time of month, or time of year.
Electrical input 210 includes male power input 222. Male power input 222 includes power input cord 224. Electrical input 210 includes female power output 226. Female power output 226 allows for multiples of power drop assembly 200 to be electrically connected in a daisy chain, where a daisy chain is an electrical connection scheme in which multiple devices are electrically connected together in sequence or in a ring.
FIG. 3 depicts an embodiment similar to FIG. 1 with electrical usage circuitry. Switching circuitry 312 of power drop assembly 300 includes electrical usage circuitry 328 for monitoring electrical usage of power cord 306. Power drop assembly 300 further includes wireless transceiver 330. Wireless transceiver 330 is communicatively connected to controller 314.
Electrical usage circuitry 328 collects electrical usage data corresponding to current through, electrical impedance of, phase shift of electrical current through, and potential difference across switching circuitry 312. Electrical usage circuitry 328 subsequently sends the electrical usage data to controller 314. Controller 314 stores the electrical usage data. Controller 314 sends the electrical usage data to a peripheral device of a user via wireless transceiver 330. The user subsequently accesses the electrical usage data via the peripheral device. The mentioned peripheral device may be any of a variety of devices, including a smart phone, a tablet, or a laptop. Electrical usage data includes a timestamp from a time when it is collected by electrical usage circuitry 328 or from a time when it is received by controller 314.
In some embodiments, the electrical usage data is analyzed to identify patterns and usage characteristics. The identified patterns and usage characteristics are compared and analyzed with respect to other data (e.g., proximity sensor data, schedule data, etc.) to determine predicted usage schedules. These predicted usage schedules enable “smart” operation where the power drop assembly 300 learns and anticipates needs. This learning behavior is optimized for reducing power consumption, for optimizing battery performance (of powered devices, for example), for providing access control, and the like. In some embodiments, long term electrical usage data is used to determine maintenance and replacement notifications for particular powered devices.
FIG. 4 depicts an embodiment similar to FIG. 1 with a power rail input. Electrical input 410 of power drop assembly 400 includes power rail input 432. Power cord housing 402 includes mounting brackets 434 mechanically attached to a top portion of power cord housing 402. Power rail input 432 receives electrical current via a powered rail. Power rail input 432 receives power using any of a variety of means, including wireless power transfer or wired power transfer.
Mounting brackets 434 include apertures 436 used to mount to a bracket attached to a support structure. For example, a rail is attached to a ceiling of a room. Mounting brackets 434 are fixed to the rail using pins attached to the rail and inserted into apertures 436. Furthermore, the pins are electrically connected to a power source via the rail. The power source transfers electrical current to power rail input 432 via said pins.
FIG. 5 depicts a side cut-away view of a power drop assembly. Power drop assembly 500 includes motor 538 mechanically attached to reel 504 and mechanically attached to power cord housing 502. Motor 538 turns reel 504 such that power cord 506 coils or uncoils around reel 504; subsequently, female power outlet 508 raises or lowers, respectively.
FIG. 6 depicts an embodiment similar to FIG. 5 with a spring. Power drop assembly 600 includes spring 640 mechanically attached to reel 604. Spring 640 is also mechanically attached to power cord housing 602. Spring 640 stores mechanical energy as power cord 606 is uncoiled from reel 604, angularly displacing reel 604. In one embodiment spring 640 is a rotational spring.
For example, female power outlet 608 is pulled with a force away from power cord housing 602. Power cord 606 is subsequently be pulled in a direction corresponding to the force such that power cord 606 is uncoiled from reel 604. Spring 640 stores energy and induce a tension in power cord 606 as a function of angular displacement of reel 604. If the force is released, then the tension in power cord 606 and the energy stored in spring 640 causes reel 604 to angularly displace and power cord 606 to re-coil about reel 604. Spring 640 stores energy as a linear or non-linear function of angular displacement of reel 604.
Power drop assembly 600 further includes damper 642 mechanically attached to reel 604. Damper 642 is mechanically attached to power cord housing 602. In one embodiment damper 642 is a rotational damper. Damper 642 dissipates energy and induces a tension in power cord 606 as a function of angular velocity of reel 604. For example, female power outlet 608 is pulled with a force away from power cord housing 602. Power cord 606 is subsequently pulled in a direction corresponding to the force such that power cord 606 is uncoiled from reel 604. Spring 640 stores energy and induce a tension in power cord 606 as a function of angular displacement of reel 604. Damper 642 dissipates energy and induce a tension in power cord 606 as a function of angular velocity of reel 604. If the force is released, then the tension in power cord 606 and the energy stored in spring 640 causes reel 604 to angularly displace and power cord 606 to recoil about reel 604. Subsequently, damper 642 dissipates energy as a function of angular velocity of reel 604 and damper 642 causes power cord 606 to coil about reel 604 with decreased angular velocity.
Damper 642 actuates when reel 604 is rotated in a first direction, and damper 642 does not actuate when reel 604 is rotated in a second direction. The first direction is rotationally opposite the second direction. For example power cord 606 is uncoiled from reel 604, which causes reel 604 to be rotated in the first direction. Subsequently, while power cord 606 is uncoiled from reel 604, damper 642 does not actuate.
Power drop assembly 600 further includes hose reel stopper 644 mechanically attached to power cord 606. Power cord 606 passes through aperture 646 in power cord housing 602. Hose reel stopper 644 prevents power cord 606 from coiling about reel 604 by having geometry which cannot pass through aperture 646 of power cord housing 602. In one embodiment hose reel stopper 644 has geometry which is spherical having a diameter of a greater magnitude than a width, length, or thickness belonging to aperture 646. Hose reel stopper 644 is adjustable to be moved to different locations along power cord 606.
FIG. 7 depicts an embodiment similar to FIG. 6 with a lock mechanism. Power drop assembly 700 includes tilt lock mechanism 748 mechanically attached to reel 704. Tilt lock mechanism 748 is also mechanically attached to power cord housing 702. Tilt lock mechanism 748 engages or disengages to, respectively, disallow or allow reel 704 to angularly displace. Tilt lock mechanism 748 engages or disengages based upon translational acceleration of reel 704 with respect to power cord housing 702. For example, a force is used to pull power cord 706 such that power cord 706 is at an angle, with a magnitude greater than a preset angle value, with respect to vertical (where vertical may mean a direction oriented with acceleration due to gravity). The force on power cord 706 causes reel 704 to accelerate along a horizontal direction (where horizontal direction may mean a direction perpendicular to vertical), engaging tilt lock mechanism 748. If the force is removed, tilt lock mechanism 748 remains engaged until power cord 706 is uncoiled by an amount from reel 704. Spring 740 coils power cord 706 in absence of the force, while tilt lock mechanism 748 is disengaged.
Power drop assembly 700 includes velocity lock mechanism 750 mechanically attached to reel 704. Velocity lock mechanism 750 is also be mechanically attached to power cord housing 702. Velocity lock mechanism 750 engages or disengages to, respectively, disallow or allow reel 704 to angularly displace. Velocity lock mechanism 750 engages or disengages based upon translational velocity of reel 704 with respect to power cord housing 702. For example, a force is used to pull power cord 706. The force on power cord 706 causes reel 704 to have an angular velocity above a preset angular velocity threshold, causing velocity lock mechanism 750 to engage. If the force is removed, velocity lock mechanism 750 remains engaged until power cord 706 is uncoiled by an amount from reel 704. Spring 740 coils power cord 706 in absence of the force, while velocity lock mechanism 750 is disengaged.
FIG. 8 depicts an embodiment similar to FIG. 1 with a light. Power drop assembly 800 includes multiple female power outlets 852 mechanically and electrically attached to power cord 806. At least one of multiple female power outlets 852 includes light 854 attached to the at least one of multiple female power outlets 852. Light 854 is electrically connected to power cord 806. Light 854 may be any of a variety of lights, including a light emitting diode (LED), an incandescent light, an arc light, or a laser light.
Switching circuitry 812 selectably connects electrically to each of multiple female power outlets 852 via power cord 806 and electrical input 810. Controller 814 instructs switching circuitry 812 to allow electrical current from electrical input 810 to flow to all of multiple female power outlets 852. Controller 814 instructs switching circuitry 812 to allow electrical current from electrical input 810 to flow to one, multiple, or none of multiple female power outlets 852. For example, Controller 814 instructs switching circuitry 812 to allow electrical current from electrical input 810 to flow to the at least one of multiple female power outlets 852, and subsequently to light 854, while disallowing electrical current from electrical input 810 to flow to any other of multiple power outlets 852.
FIG. 9 depicts an embodiment similar to FIG. 8 with a sprinkler. Power drop assembly 900 includes multiple female power outlets 952. At least one of multiple female power outlets 952 includes sprinkler system 956 attached to the at least one of multiple female power outlets 952. Sprinkler system 956 is also electrically connected to power cord 906.
Sprinkler system 956 includes water supply line 958 and sprinkler 960. Sprinkler 960 is fluidly connected with water supply line 958 such that sprinkler 960 draws water from water supply line 958 and sprinkle said water. Sprinkler system 956 actuates to sprinkle water when the at least one of multiple female power outlets 952 receives current flow or a electrical potential difference from electrical input 910 via switching circuitry 912 and power cord 906.
FIG. 10 depicts an embodiment similar to FIG. 1 with a circuit breaker. Switching circuitry 1012 of power drop assembly 1000 includes circuit breaker 1062. Circuit breaker 1062 connects electrical input 1010 to power cord 1006. Circuit breaker 1062 disallows electrical current to flow from electrical input 1010 to power cord 1006 if a magnitude of electrical current flowing through circuit breaker 1062 is greater than a preset current flow threshold. In some embodiments circuit breaker 1062 is reset manually or via switching circuitry 1012. For example, a magnitude of electrical current flowing through circuit breaker 1062 greater than the preset electrical current flow threshold, circuit breaker 1062 disallows current to flow from electrical input 1010 to power cord 1006. Switching circuitry 1012 subsequently sends circuit breaker state data to controller 1014. Controller 1014 processes the circuit breaker state data. Controller 1014 alerts a user that circuit breaker 1062 has disallowed current flow from electrical input 1010 to power cord 1006. Controller 1014 receives instructions from the user. Controller 1014 sends restart instructions to circuit breaker 1062. Circuit breaker 1062 subsequently allows electrical current to flow from electrical input 1010 to power cord 1006. Controller 1014 is programmed to automatically send restart instructions to circuit breaker 1062. In certain embodiments the automatic reset is programmed to occur after a preset period of time. In certain embodiments the controller 1014 is programmed to lock down the circuit breaker until the user enters password information.
In certain embodiments circuit breaker 1062 is a relay electrically connected to controller 1014 via wiring 1064. Controller 1014 applies an electrical current and/or an electrical potential difference across wiring 1064 such that circuit breaker 1062 disallows or allows electrical current to flow from electrical input 1010 to power cord 1006.
