AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION Standard Patent Applicant(s): Smart Openers Pty Ltd Invention Title: Wireless Receiver for Door Operator The following statement is a full description of this invention, including the best method for performing it known to me/us: P78440AU i PatSotFihng Application 2009--27.doc (M) - 2 WIRELESS RECEIVER FOR DOOR OPERATOR Field of the Invention 5 This invention relates to wireless receiver for a door operator for opening and closing a door, a gate, a window or like closure panel hereinafter referred to as door. The invention has particular, although not exclusive application, in the art of garage doors, or 10 gates that are provided across roadways such as driveways to houses. Background 15 Hitherto, it has been known to provide wireless receivers for operators for opening and closing a door. Such operators typically comprise an electric motor for driving the door to the opened and closed positions. A control circuit is provided within the operator or 20 receiver to process signals input by a user to operate the motor to move the door to the opened and closed positions. There are many different types of operators and some work on roller shutter doors, others work on tilt doors, others work on sectional doors, others work on gates or windows 25 or similar closure panels. In the case of gates, there are swing type gates and sliding gates. All the above, and any other like closure panel such as windows are to be considered within the term "door" as used hereinafter. 30 Typically, the known operators have a DC electric motor. Typically also, such operators incorporate a remote radio control feature to enable a user to open and/or close a door remotely by activating a remote transmitter. The operator has a receiver associated 35 therewith for wireless communication of user initiated door operation signals from the transmitter such that the operator can be activated to cause the motor to drive the N:\Melboume\Cases\Patent\78000-78999\P78446.AU.1\Specis\P78446.AU.1 - Specification as lodged doc 27/07/09 - 3 door to the opened and/or closed positions. Typically, the required transmitter/receiver combination has a code matching facility whereby only paired transmitter/ receivers will cause activation of the motor to drive the 5 door to the opened and/or closed positions. Various types of code matching features are employed. In some cases multiple transmitters can be paired with a receiver so that multiple transmitters can be used to operate the operator. Further, in some instances, multiple door 10 operators may be provided and a single transmitter is utilised to operate respective ones of the multiple doors by operating appropriate buttons on the transmitter. Each operator or receiver needs to be suitably code matched so that a respective and required door will move to the open 15 and/or closed positions without others being moved. In the above arrangements, an electric circuit board within the operator or the receiver contains a hard wired memory for storing code parameters of the transmitter 20 which are then used for code matching purposes. Such memories can typically comprise hard wired memory provided on a circuit board or alternatively, memory available within CPU's used for processing signals received to initiate movement of the door to the opened and/or closed 25 positions. Desirably, such memory is non-volatile so that in the event of a power failure, the stored code parameters are still retained within the memory for use when the power is 30 restored. A problem exists with the known arrangements should the operator circuit board or the receiver fail for any reason. In such circumstances, it is necessary to install 35 a replacement circuit board or receiver and to then re code match, and pair one or more transmitters with the operator or receiver. If only one transmitter is used, N \Melboume\Cases\Patent\78000-78999\P78446 AU.1\Specis\P7B446.AU 1 - Specification as lodged.doc 27/07/09 - 4 the code matching is not a major task. However, in apartments where there is a single door to a car park, there may be many hundreds of transmitters that each need to operate with the operator to cause opening and closing 5 of the door. In such cases, it has been necessary to re code match and pair every transmitter with the operator or receiver, and this has been an enormous problem. Further, some operators employ a shaft encoder that 10 provides electric signal pulses to indicate respective opened and closed door stop positions of the door. The shaft encoder is rotated as the door moves and when a particular count signal is reached, it signifies that the motor is to stop. The count value signals for the opened is and closed stop positions are also stored in the memory. If the circuit board should fail and require replacement, then the set count values also need to be re-entered which is troublesome. 20 Further, some operators remain in service for many years and use original system software. If there should be a problem with any part of the operator which necessitates a service call then it is desirable to update the system software to the latest version. Typically this 25 is done by the service person carrying a laptop computer that carries the latest version of that software. A physical connection is then made between the laptop computer and the circuit board in the operator via an RS232 port connector and an update procedure is invoked to 30 transfer the latest version to the microprocessor on the circuit board in the operator. This presents two problems: 1. Laptops are expensive and fragile and can be 35 lost, stolen, or dropped and broken. N.\Melboume\Cases\Patent\78O0-78999\P78446 AU.1\Specis\P78446.AU.1 - Specification as lodged.doc 27/07/09 - 5 2. The case of the operator needs to be opened to make the physical RS 232 port connection. 3. Further, the use of a laptop requires an 5 installer person special skill set, and the process is also time consuming as the laptop computer requires to boot-up and the correct software loaded. This can typically take 20 minutes. 10 There is a need for an improved way to upload the latest version software.

Brief Description of Drawings 30 In order that the invention can be more clearly ascertained, examples of embodiments will now be described with reference to the accompanying drawings wherein: 35 Figure 1 is a block circuit schematic diagram showing components of an example of an embodiment of the invention, N:\Melboume\Cases\Patent\780O0-78999\P78446.AU 1 Specis\P78446.AU 1 - Specification as lodgeddoc 27/07109 - 8 Figure 2 is a diagrammatic side view showing a typical operator embodiment incorporating removable memory, 5 Figure 3 is a view similar to that shown in Figure 2 showing incorporation of removable memory and further memory in the form of a non primary memory, 10 Figure 4 is a block schematic diagram showing circuit components associated with storage of shaft encoder pulse count values used for determining the opened and/or closed stop positions of the door, is Figure 5 is a block schematic diagram showing a receiver/transmitter with a code matching circuit, AND Figure 6 is a block schematic diagram showing the components of an operator and operator circuit board with 20 a system software update feature. Detailed Description of Embodiments Referring firstly to Figure 1, there is shown a door 25 operator indicated generally by numeral 1. The operator 1 includes an electric motor 3 which is typically a DC electric motor but may be an AC electric motor. The motor 3 is drive connected to open and close a door 5 through an appropriate drive coupling 7 which is shown in 30 diagrammatic form only. There are many and varied different drive couplings 7. The inventive concepts herein are not concerned with the particular drive coupling. The motor 3 is electrically connected with a control circuit 9 which is used to switch ON the motor 3 35 in response to user initiated requests to open and/or close the door 5. The operator 1 has a radio receiver 11 and one or more transmitters 13 that can be code matched N.\Melboume\Cases\Patent\78000-78999\P78446.AU.1\Specis\P78446.AU.1 - Specification as lodged.doc 27/07/09 - 9 and paired with the receiver 11 so that only appropriate code matched and paired transmitters 13 will cause the operator 1 to activate the motor 3. A code matching circuit 15 is provided so that received signals at the 5 receiver 11 can be processed to determine if there is a code matched from a transmitter 13. The code matching circuit 15 may be incorporated within the receiver 11, or within the operator control circuit 9, or be an independent code matching circuit as diagrammatically io shown. Typically, the control circuit 9 is controlled by an internal CPU (not shown) which is suitably programmed to provide the necessary control functions to the motor 3. is These can be control functions to permit the direction of the motor 3 to change to reverse a direction of travel of the door. There may be provided door obstruction sensing features which detect a change operating parameters of the motor 3, such as excessive current draw, which indicates 20 that the door has struck an object. In such cases, the control circuit 9 can operate to reverse the direction of travel of the door 5. In other cases an internal access light can be illuminated for a predetermined time following activation of the motor 3. Other control 25 functions known in the art can be incorporated. Figure 1 diagrammatically shows a removable memory 17 for storing code parameters of the transmitter used for code matching purposes. Thus, when a transmitter 13 is 30 code matched and paired with a receiver 11, the particular code of the transmitter, or a code related thereto, can be stored in the removable memory 17 under control from the CPU in the control circuit 9. In this way, when a transmitter 13 and receiver 11 are initially code matched 35 and paired, the CPU in the control circuit 9 will have a function to store the particular transmitter code 13, or a code related thereto, in the removable memory 17. This N:\Melboume\Cases Patent\78000-78999\P78446.AU 1\Specis\P78446 AU.1 - Specification as lodged doc 27/07109 - 10 process will be repeated for each particular transmitter 13 which is required to be code matched and paired with the receiver 11. The operator 1, can be arranged via code matching circuit 15 and/or the control circuit 9 to 5 interrogate the removable memory 17 during code matching to determine if the removable memory 17 contains a particular code for the particular transmitter 13. In such instances, if a match is determined, then the particular signal received can be used to activate the 10 motor 3 via the control circuit 9. Some transmitters 13 and receivers 11 have a random code matching code feature where an initial code is used as a seed for generation of a subsequent random code. 15 This is used to inhibit against the unlikely event that some malicious intending person were to scan a transmitted signal from a transmitter 13 to detect the code and then replicate that code to subsequently attempt activation of the operator 1. Unless the original code is known, then 20 the next code cannot be determined. Accordingly, the removable memory 17 will contain the appropriate code for the necessary code matching process, and the code matching circuit 15 and/or the CPU in the control circuit 9 will be suitably programmed so that subsequent operation of the 25 transmitter 13 with a code matched and paired receiver 11 will generate a match for subsequent operation of the transmitter 13 according to the random nature. The removable memory 17 is non-volatile memory such 30 that any code stored will remain with the removable memory should power be removed from the operator 1, or the removable memory removed from the operator. Typically, the removable memory 17 can comprise known removable memory devices such as one of, a flash card, a compact 35 flash card, a USB memory stick, or similar memory. Figure 2 shows an example of a door operator 1 N:\MeIboume\Cases\Patent\78OOO-78999\P78446OAU.1\Specis\P78446 AU.1 - Specification as lodged.doc 27/07109 - 11 incorporating the example of Figure 1 for operating a roller door 19. It should be realised that the roller door 19 is only one example of a type of door for which the invention can be used. Any other type of door which 5 can be operated by the operator 1 is not excluded. Here it can be seen that the operator 1 has an external casing 21. There is a drive motor in an upper part, and a control circuit 9 in a lower part. The operator 1 has a user interactive panel 23 with control buttons that enable 10 local manual operation of the operator 1 to open and or close the door and to facilitate code matching and pairing of transmitters 13 with a receiver 11 (not shown) contained within the casing 21. The casing 21 has an exposed memory socket 25 into which the removable memory 15 17 can be plugged. Accordingly, it can be seen that the removable memory 17 can be accessed externally of the casing 21 without opening or removing the casing 2. Accordingly, if the operator 1 should fail and require replacement of the operator 1 or the control circuit 9, 20 then the removable memory 17 can be readily user removed and inserted into the replacement operator 1 or control circuit 9 carrying the codes of the code matched and paired transmitters 13 and receiver 11. This obviates the need to re-code match and pair the transmitters 13 with 25 the receiver 11. Whilst the removable memory 17 has been shown in a clear visible and exposed position, it may also be provided within a compartment that has a user readily openable cover. In that way, the external appearance of the casing 21 of the operator 1 may be enhanced relative 30 to that shown in Figure 2 as the memory and socket therefore will be within the compartment and not physically exposed as shown in Figure 2. Figure 3 shows an alternative example to that shown 35 in Figure 2 where like components are provided with the same numerical designations. Here, the removable memory 17 is shown internally of the casing 21 and represents a N:\Melboume\Cases\Patent\78000-78999\P78446.AU-1\Specis\P78446.AU 1 - Specification as lodged.doc 27/07/09 - 12 primary removable memory. There is also provided further memory 17' which represents an auxiliary non primary memory which is accessible externally of the casing, as in the example of Figure 2. In the example in Figure 3, the 5 primary removable memory 17 is retained internally within the casing of the operator 1 and accessible for removal only when the casing 21 is opened or removed. In this case, there are two removable memories provided with the operator 1 each held within respective memory sockets. 10 During code matching of transmitters 13 with receiver 11, the required codes are stored on both of the primary removable memory 17, and the auxiliary memory 17'. In the example of Figure 3, the auxiliary memory 17' can be removed from the memory socket 25 and kept in a remote 15 place of security. Accordingly, if there is a fire or other major damage to the operator 1, the codes that are stored in the removable memory 17 internally of the casing 21 will be destroyed. The codes stored in the removable memory 17' are then available as a back-up for use in 20 another environment such as another operator 1, or control circuit 9. During interrogation of memory for codes for code matching purposes, the primary memory can be first interrogated and if no code match is found then the further memory 17' can be interrogated to attempt to find 25 a code match. If a code match is found in the further memory 17', then a routine may be involved to transfer that code to the primary memory 17 automatically, so it will then be replicated with the primary memory 17. 30 Figure 4 shows a further example where the operator 1 utilises a shaft encoder 27 that generates pulse signals representing the position of the door 5 as the door 5 is moved. In this case, the opened stop position and the closed stop position of the door 5 are determined by 35 respective count value signals of those pulse signals. The pulse signals are provided from the shaft encoder 27 to the control circuit 9 such that when a particular count N:\Melboume\Cases\Patent\78000-78999\P78446.AU \%Specis\P78446 AU 1 - Specification as lodged doc 27/07109 - 13 value is reached, the motor 3 can be switched OFF. In this case, the removable memory 17 is provided to store the respective count values for the opened stop position and the closed stop position. 5 The operator 1 shown in Figure 4 may comprise an "open" manual switch 29 and a "close" manual switch 31 which can be operated manually locally at the operator 1 to trigger operation of the motor 3 in the required 10 direction of rotation. As can be appreciated, the block circuit schematic diagram shown in Figure 4 is for a slightly different embodiment to that shown in Figure 1, however, the features of block schematic circuit 4 can be incorporated with the features of the block schematic 15 circuit of Figure 1. The memory 17 may comprise further memory 17' as explained in relation to Figure 3. It should also be appreciated that the control circuit 9 may be arranged to operate the motor 3 to travel 20 in one direction on receipt of a signal that is code matched from a transmitter 13, and that when the transmitter 13 operates a subsequent time, to cause the direction of rotation of the motor 3 to be opposite to that during the last operation. In this way, the 25 respective opened and closed manual switches 29 and 31 are not needed and only a single manual switch is needed which will change the direction of rotation of the motor on each operation of the switch. 30 The example shown in Figure 4 provides that the respective count values for the opened stop position and the closed stop position are stored in the removable memories 17 and 17' such that if the operator 1, or parts thereof need to be replaced, the count value signals can 35 be carried with the removable memory and used within the new operator 1 without resetting of the opened stop position and or closed stop position of the door 5. These N:\Melboume\Cases\Patent\78000-78999\P78446.AU 1\Specis\P78446 AU.1 - Specification as lodged doc 27/07/09 - 14 may be in addition to codes stored for code matching. Figure 5 shows a block schematic diagram of a receiver/transmitter with a code matching circuit. Here, 5 a receiver 31 contains a wireless receiving unit 11 (as per the previous examples). A transmitter 33 is provided to communicate with the receiving unit 11. The receiver 31 includes a code matching circuit 15 as in the previous examples. The receiver 31 also contains a removable 10 memory 17 and/or 17' as described in the previous example. In this example, a transmitter 33 transmits a signal which includes a code signal identifying the transmitter 33 requesting opening or closing of the door. This signal is received by the receiver 11 and code matching is performed is by the code matching circuit 15. The removable memory 17 is accessed by the code matching circuit 15 to enable a code matching to be determined from any stored codes. If a match is found, then an output signal 35 is provided which is conveyed to the control circuit 9 as in the 20 previous examples. The receiver 11 may incorporate a CPU for processing received signals and for enabling codes to be stored in a removable memory 17/17'. Accordingly, in this example, the receiver 31 is a stand alone unit that can be hardwired to convey the output signal 35 to a 25 conventional operator 1 that may not have a remote radio control feature, or one where there needs to be an update to incorporate the features of the present invention. In other words the receiver 3, can be retro-fitted to an existing operator 1. The receiver 31 may be provided 30 within its own housing and mounted adjacent the door operator 1 or alternatively it may be incorporated internally within a casing of a door operator 1. The removable memory 17/17' can be stored in any of the ways previously referred to. Thus, in this example, all the 35 advantages of utilising a removable memory 17 for storing code parameters of matched and paired transmitters 33 with receiver 11 can be utilised. For this reason, we have not N:\Melboume\Cases\Patent\78OOO-78999\P78446.AU. 1\Specis\P78446.AU1 - Specification as lodged doc 27107/09 - 15 replicated a description of the same features for this example as reference can be made to the previous examples to obtain an understanding. 5 In the examples described above the operator may have a program feature that first checks for door operator code or count values in the primary memory 17, and then to interrogate the auxiliary memory 17' if a code match or count value is not found in the primary memory 17. 10 Referring now to Figure 6 there is shown a block schematic circuit diagram of components of an operator circuit board with a system software update feature. Like components referred to in previous embodiments have 15 been provided with same numerical designations. The circuit board contains a control circuit 9 that includes a microprocessor (not shown) for effecting control functions associated with the operator. A memory 39 is provided which is a resident memory and may, in fact, be part of 20 the microprocessor within the control circuit 9. A control panel 41 is connected with the control circuit 9 to enable a user to input commands locally at the operator using input means such as push buttons diagrammatically shown. The control panel 41 is therefore a user interface 25 to the operator. The circuit board 37 and the motor 3 are typically mounted together immediately adjacent the door to be opened by the operator. The control panel 41 has, in this embodiment, a display screen 43 whereby program modes and other operating features of the operator can be 30 displayed to enable a user to appropriately adjust the settings of the operator for particular door environment and characteristics. The control circuit 9 has the microprocessor therein programmed to operate using particular operation software. The user input means on 35 the control panel 41 enable a user to call up particular setting parameters such as code matching features for the transmitter (not shown in this example), physical stop N :\elboume\Cases\Patent\7800-78999 P76446.AU.1\Specis\P78446 AU1 -Specification as iodged.doc 27107/09 - 16 positions for the door, type of door and other known features. Typically, a programming mode is entered to activate these features by using particular ones of the user input means, such as the push buttons shown. The 5 control circuit 9 has a memory socket 25 such as a USB socket connected therewith and operatively positioned so that it is user accessible from outside of the casing of the operator. A memory 45 such as a USB memory can then pug in to the memory socket 25 externally of the casing to 10 enable access to contents of the memory 45. The microprocessor (not shown) within the control circuit 9 can contain a routine in the software to interrogate the memory 45 to determine if the memory 45 15 carries system software which is a newer version than the version resident within the microprocessor and/or within the memory 39. This may be programmed to occur automatically on insertion of the memory 45 into the memory socket 25 or it may be activated in response to 20 entering a programming mode on the control panel 41. In the event that the memory 45 carries system software that is a newer version than the version carried by the control circuit 9 in the microprocessor therein or in the memory 39, then a routine can be implemented to download the 25 updated software from the memory 45 and to replace the previous version of the software. In this way, the control circuit 9 may be updated to the latest version system software without the need for 30 opening the casing of the operator and without the need for a laptop computer or similar computer device which has been required in the past. By using this feature to update the system software, all the aforementioned disadvantages of the known operators and system update 35 software have been overcome. The memory 45 can be an inexpensive USB memory which can be carried by the service person and/or obtained easily by the owner of the operator N:\Melboume\Cases\Patent\78000-76999\P78446 AU 1\Specis\P78446.AU.1 - Specification as lodged.doc 27/07/09 - 17 to permit easy update of the system software. If required the memory may be provided to the owner of the operator for safe keeping. 5 It should be appreciated that the above embodiment may incorporate one or more of the features of the embodiments previously disclosed. It should also be appreciated that the control panel may not have a display 43. In such case, there can be a routine provided within 10 the resident software in the control circuit 9 to interrogate the memory 45 and to automatically update the system software version to the latest version carried by the memory 45 without the user requiring to physically view instructions or other information presented on the 15 display 43. It should be appreciated that display 43 can typically comprise an LCD display or other suitable display. It should be realised that the examples described 20 above could be modified in many ways as would be apparent to persons skilled in the door operator arts and/or the electronic arts without departing from the ambit of the invention the nature of which is to be determined from the foregoing description. 25 It is to be understood that, if any prior art publication is referred to herein, such reference does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia 30 or any other country. In the claims which follow and in the preceding description, except where the context requires otherwise due to express language or necessary implication, the word 35 "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to N:\Melboume\Cases\Patent\78000-78999\P78446.AU-1\Specis\P78446.AU 1 - Specification as lodged doc 27/07/09 - 18 preclude the presence or addition of further features in various embodiments of the invention.
