FIELD OF THE INVENTION
The present invention relates to electronic and electrical appliances generally and to a system and method of remotely controlling these appliances in particular.
BACKGROUND OF THE INVENTION
Remote control devices to allow a user to remotely control the operation of electrical and electronic appliances are well known and have been around for many decades. In the earlier days, manufacturers configured appliances to operate with a dedicated remote control device which was programmed with a particular identification code which allowed the device to pair with the appliance, generally communicating using infrared (IR) or radio frequency (RF) communications to control the device. Each appliance required its own remote control device so that a household frequently found itself with numerous remote control devices for controlling the various televisions, air conditioners, and other controllable appliances generally found in a typical home.
In order to solve the problem of dealing with multiple remote control devices, universal remote control devices were developed. These were preprogrammed with a relatively large number of identification codes which allowed the device to pair with those appliances whose identification codes were among those programmed into the device, thereby allowing control of numerous appliances. Nevertheless, these universal remote control devices were limited to controlling only those appliances whose identification codes were preprogrammed into the device, and required extensive amounts of time to locate the correct identification code for each appliance from among all those stored in the device.
With technological advancements and the increase in popularity of the Internet, universal remote control devices were developed as part of systems which could access databases through the Internet in order to download the identification codes to the devices. These databases generally stored a large number of identification codes suitable to allow the remote control devices to communicate with and control a large number of appliances of different types and from different manufacturers. An example of such a system is described in U.S. Pat. No. 7,586,398 B2 to Huang et al., which discloses “A system and method for using an RFID tag to automatically setup and configure a universal remote control to command appliances of various types and various manufacturers”. Another example of such system is described in US Patent Application Publication No. 2012/0295662 A1 to Haubrich which discloses “A universal remote control system and method for employing a centralized database for programming the universal remote control (URC) to control the operation of appliance(s). The appliance(s) may or may not be made by different manufactures. The centralized database is accessible via the Internet and includes many different appliances made by many different manufacturers. The user may access a web site of the centralized database and manually enter electronic appliances identifying data that the URC is desired to operate, and then the centralized database sends the appropriate command code data to the URC either directly or temporarily downloads them into a computer to be later loaded into the URC. The centralized database includes command codes for appliances such as TV sets, DVDs, CD systems, alarm clocks, and VCRs, music synthesizers, toys, stereo systems, ovens, washing machines, timers, power strips, and the like”.
More recently, with the explosive increase in the global use of smartphones and their continuously-expanding processing power, the trend is to implement universal remote control devices in the smartphones. Numerous application programs have been developed which allow a user to control electronic multi-media devices and other electronic and electrical appliances from a smartphone. U.S. Pat. No. 8,519,820 B2 to Cannistraro discloses “Systems and methods for saving and restoring scenes in a multimedia system with minimal configuration are provided. The techniques of the present invention can allow the states of the components in the multimedia system to be captured in a scene. Once the scene has been saved, the scene can be restored at a later time. A remote control system for recommending scenes by comparing states of components in the current scene with states of components in saved scenes is also provided. The remote control system can also recommend scenes based on usage patterns. Moreover, the remote control system can allow users to designate one or more saved scenes as favorite scenes”.

Applicants have realized that one of the major drawbacks with known universal remote control devices is that they generally require configuring the device and the appliance to be controlled, to make them compatible for most, if not all, modes of operation. This compatibility issue generally applies both to the older handheld dedicated universal remote control devices as well as to the newer, Internet-connectable mobile devices, including smartphones (the Internet-connectable mobile devices may also be referred to hereinafter as “remote control device”, “universal remote control device” or “device”). This typically requires that a user search for the identification code of each appliance which is to be controlled, and may additionally require that the user configure a set of parameters in each appliance and/or in the remote control device to pair the devices for each mode of operation. Performing these tasks may require that the user have some technical understanding of each appliance's operation, and frequently may result in user failure to successfully configure the remote control device and/or the appliance with the correct parameters. Not only may this be very frustrating for the user, but many times, the user may be faced with little choice but to call a technician to come to perform the configuring (which may be expensive and time consuming).
Applicants have further realized that a universal remote control system which is based on using an event-driven architecture substantially overcomes the previously described drawback of requiring the user (or somebody on his behalf) to configure the remote control device and/or the appliances. Therefore, disclosed herein is a universal remote control system based on an event-driven architecture (EDA) which may individually and/or collectively control different types of electronic and electrical appliances. In the EDA, each application in an appliance is associated with a state machine configured to send messages to, and receive messages from, other state machines. The state machines may also be configured to monitor message transmissions between other state machines. The EDA may include an event and message handler (hereinafter referred to as “switch”) which may act as a message broker to automatically handle the transfer of messages between state machines, and a conflict manager to automatically resolve conflicts in transmitted messages between state machines.
The state machines may all be associated with a particular appliance, or with several appliances whose operation may be interrelated. Consequently, it may be appreciated, the remote control system may allow use of a single remote controller to individually control different types of appliances, and may additionally allow jointly controlling different appliance and types of appliances as a single appliance set.

Reference is now made to FIG. 2 which schematically illustrates a functional diagram of an exemplary EDA 200 for use in universal remote control system 100, according to an embodiment of the present invention. EDA 200 may include a switch 202 (message broker) and a conflict manager 204 which may be implemented in computing device 100 described in FIG. 1, for example, in state machine module 123. EDA 200 may additionally include one or more state machines 206, for example state machines 1-4 as shown although many more state machines may be included.
Each state machine 206 may represent a logical unit which may be used to process a set of scenarios based on a set of autonomic states (i.e. an event handler) associated with each appliance, and may be capable of receiving messages from other state machines and sending messages to other state machines. The messages may include a message code associated with each state machine which may be used for identification purposes and which may be used for discovery and pairing state machines with one another.
Communications between state machines 206 may be through switch 202 which may act as a message broker. Conflict manager 204 may serve to interrupt messages sent from switch 202 to targeted state machines and may process the “interrupted” message and decide whether or not to block the message, to send as is, or to create and send another message instead.
In EDA 200, each state machine 206 may support a logical unit which may be created to handle message logics and to optionally transmit messages to other state machines via switch 202. Generally, each state machine 206 may register itself in switch 202 by registering relevant message codes it may be interested in receiving from the switch (stored in state machine register 125), and may then implement an event handler for each message code which is registered when a message arrives from the switch. Similarly, each state machine 206 may register itself in conflict manager 204 to monitor and report any messages with message codes which may be of conflict (stored in state machine register 125).
Reference is made to FIG. 3A which schematically illustrates a functional diagram of EDA 200 with state machines 206 registered to switch 202 and conflict manager 204, according to an embodiment of the present invention. As may be appreciated from the figure, for exemplary purposes, state machine 1 is registered with switch 202 to receive messages with message code A while state machine 2 is registered with the switch to receive messages with message code A and/or with message code B. The registration of each state machine 206 associated with each particular code may be stored in switch 202 in a message code database 208 (see FIG. 4) in state machine register 125. Message code database 208 may include a registration list 210 wherein may be listed, for each message code, the state machines which have registered to receive messages with that particular message code (see FIG. 4). For example, message code database 208 may include a registration list 210 for message code A which may include state machine 1 and state machine 2, and may include a second registration list 210 for message code B which may include only state machine 2.
State machines 3 and 4 are registered with conflict manager 204 to monitor message with message codes A and B, respectively. Similarly to switch 202, registration of each state machine 206 associated with each particular code may be stored in conflict manager 204 in a message code database 216 (see FIG. 5) also in state machine register 125. Message code database 216 may include a registration list 218 wherein may be listed, for each message code, the state machines which have registered for monitoring messages with that particular message code (see FIG. 5). For example, message code database 216 may include a registration list 218 for message code A which may include state machine 3, and may include a second registration list 218 for message code B which may include only state machine 4.
Reference is now also made to FIG. 3B which schematically illustrates a process diagram of EDA 200 based on the state machine registrations depicted in FIG. 3A, according to an exemplary embodiment of the present invention. It may be appreciated by the skilled person that the steps shown for the exemplary process are not intended to be limiting and that the process may be practiced with more or less steps, or with a different sequence of steps, or any combination thereof.
At 301, state machine 1 may send a message with a message code A to switch 202;
At 302, switch 202 may transfer the message to conflict manager 204 for conflict checking (to determine whether or not there is conflict);
At 303, conflict manager 204 may transfer the message to state machine 3 who is registered with the conflict manager to monitor messages with message code A. Based on the response received from state machine 3, conflict manager 204 may prevent switch 202 from transferring the message, may alter the message prior to transferring by the switch, or may instruct the switch to transfer the message as is;
At 304, state machine 3 may return an OK message to conflict manager 204 indicative that there is no conflict;
At 305, conflict manager 204 may instruct the switch 202 to send the message as is. Alternatively, should state machine 3 return an indication of conflict, conflict manager 204 may alter the message and send the altered message to switch 202 for transfer to the target state machines, or may cancel sending the received message completely;
At 306, switch 202 may transfer the message with message code A to state machine 2 which is registered with the switch to receive message code A; and
At 307, switch 202 may transfer the message with message code A to state machine 1 which is also registered with the switch to receive message code A.
Reference is now made to FIG. 4 which schematically illustrates a functional process diagram of data flow in switch 202, according to an exemplary embodiment of the present invention. It may be appreciated by the skilled person that the steps shown for the exemplary process are not intended to be limiting and that the process may be practiced with more or less steps, or with a different sequence of steps, or any combination thereof.
At 401, state machine 206 may send a message to switch 202;
At 402, a message processor 212 in switch 202 may check in message code data base 208 for all state machines registered in registration list 210 to receive a message with the message code of the message received from state machine 206;
At 403, message processor 212 may generate one or more messages 214 responsive to the received message for sending to all state machines listed in the associated registration list 210; and
At 404, message processor 212 may send message 214 to conflict manager 204 for conflict checking.
Reference is now made to FIG. 5 which schematically illustrates a functional process diagram of data flow in conflict manager 204, according to an exemplary embodiment of the present invention. It may be appreciated by the skilled person that the steps shown for the exemplary process are not intended to be limiting and that the process may be practiced with more or less steps, or with a different sequence of steps, or any combination thereof.
At 501, conflict manager 204 may receive a message from switch 202;

Examples of state machines which may be used in EDA 200 may include a GUI General State Machine, an Appliance State Machine including an Appliance GUI State Machine, a Platform State Machine and an Infra State Machine including an Infra GUI State Machine, and a Feature State Machine including a Feature GUI State Machine. FIG. 6B is a block diagram showing exemplary state machines which may be used in universal remote control system 100, a description of each major type provided herein below, according to an exemplary embodiment of the present invention.
a. GUI General State machine: this state machine may be used to load the first activity and to manage the behavior of activities which are not related to any specific feature. As an example, this state machine may implement an activity including an appliance's manufacturer's logo such as may appear in a first screen displayed at the start of an execution of an application on screen 148.
b. Appliance State machines: these state machines may manage the background tasks which may be relevant to a specific Appliance Type or to a specific Appliance Element, and may be subject oriented with specific Appliance types potentially implementing some state machines. Examples of some background tasks may include discovery functions, pairing functions, control commands, among others.
c. Appliance GUI State machines: these state machines may manage the GUI to allow the user to operate the Appliances. The Appliance GUI State machines may optionally be implemented in the Appliance State machines. Examples of some types of operations which may be carried out are pairing, control commands, and activation commands, among others.
d. Platform State machine: this state machine may manage the computing device's functionality. An example may include the detection of the existence of IR or of WIFI availability, among others.
e. Infra State machines: these state machines may be used by other state machines as utility or tools. An example of an Infra State Machine may be a Persistency State Machine which is a state machine which may be used by all state machines to store and retrieve persistent information.
f. Infra GUI State machines: these state machines may be used by other state machines (i.e. background state machines) but may include a GUI User Interface. An example of such a state machine may be a Settings GUI State Machine which may be used by all state machines to configure the system. Each state machine which registers to the Settings State Machine may have a section in the settings layout allowing it to be configured.
g. Feature State machine: this state machine may implement a specific feature that may be used in more than one Appliance. For example, a monetary state machine may be used as a controller over the other state machines to monitor whether a specific functionality is authorized from a monetary perspective. Another example may be an IR state machine which may be used as an IR controller to send IR commands to an Appliance.
h. Feature GUI State machines: these state machines may be used by other state machines (i.e. background state machines) but may include a GUI User Interface, and may be included in their background state machines. For example, a Monetary GUI State Machine may be used to interface the user to enable operating the monetary aspects of an application.
Applicants have realized that GUIs used in computing devices used to remotely control appliances are generally limited in their functionality. The GUI is typically designed to control a specific appliance or a specific type of appliance, for example TVs, and therefore many different GUIs may be required to control different appliances or types of appliances. As a result, a user wishing to control a number of different appliances or types of appliances may find him or herself working with a number of different GUIs on his or her computing device. As may be clearly appreciated, this may tend to be very cumbersome and confusing. Some attempts have been made to solve the above problem using a single GUI with control functions hierarchically arranged, but these require that the user continuously move back and forth between screens in order to access all the control buttons, again making the remote controller cumbersome and confusing. Furthermore, these remote controllers are generally suitable for controlling a single type of appliance (e.g. TV), and not for different types of appliances.
Applicants have realized that the flexibility provided by combining the use of selection wizard module 124 and control panel hierarchy module 126 in an EDA of the present invention may provide for a GUI which may allow controlling different appliances and different types of appliances with the same GUI. Furthermore, the same GUI may be used with most, if not all, the computing devices configurable with the selection wizard module and control panel hierarchy module and suitable to operate using the EDA of the present invention.
Reference is made to FIG. 7 which schematically illustrates an exemplary functional layout of a GUI 700 suitable for use with computing device 100, according to an embodiment of the present invention. As may be appreciated from the figure, the layout may be hierarchically arranged, for example, into four hierarchical levels as shown with APPLIANCE GROUPS 1-4 on a first level, APPLIANCE 20-23 on a second level, PANEL 210-213 on a third level, and ELEMENT 2110-2113 on a fourth level.
GUI 700 may be divided in display 120 into sections to allow selector buttons associated with control functions corresponding to one or more hierarchical levels to be simultaneously displayed on display 120, allowing a user to access the control functions at all levels without having to move back and forth between screens or menus as is typically done in the art with hierarchically-arranged GUIs. For example, appliance type selector buttons 702 may be allocated a portion of display 120 to allow selection of an appliance type from different types of appliances or to allow selection of an appliance set from a group of different appliances (APPLIANCE GROUP 1-4). Appliance selector buttons 704 may be allocated another portion of the display to allow selection of an appliance from different appliances (APPLIANCE 20-23) which may be controlled and are associated with a selected appliance type. Panel selector buttons 706 may be allocated another portion of the display to allow selection of a panel from the different panels (PANEL 210-213) which may be controlled and are associated with a selected appliance. Element selector buttons 708 may be allocated another portion of the display to allow selection of an element from the different elements (ELEMENT 2110-2113) which may be controlled and are associated with a selected panel.
In an exemplary mode of operation and referring to FIG. 7, a user wishing to control an appliance may refer to selector buttons 702 and may select APPLIANCE GROUP 2 (e.g. air conditioners) as the type of appliance to be controlled. Upon selecting APPLIANCE GROUP 2, selector buttons 704 may be displayed identifying all air conditioners which may be controlled. Upon the user selecting APPLIANCE 21 (e.g. Whirlpool air conditioner model XXX) as the appliance to be controlled, selector buttons 706 may be displayed identifying all panels associated with the different controllable functions of APPLIANCE 21. These may include, for example, a panel for programming cooling functions in the air conditioner, a panel for programming heating functions, a panel for room activation, among many different panels. Upon the user selecting PANEL 210, selector buttons 708 may be displayed identifying the elements associated with the selected panel, ELEMENT 2110-2113. The user may then select the desired element or elements, for example, for setting room cooling temperature, on/off hours, rooms to be cooled, etc.
It may be appreciated, as previously described, that GUI 700 may also be used to allow a user to control appliance sets and not only appliances. GUI 700 may allow the user to build appliance sets (which may be based on instructions generated by selection wizard module 124) which may be included as an APPLIANCE GROUP, for example, APPLIANCE GROUP 3. The appliance set may include, for example, a cinema set, which may integrate joint control of a stereo system, a television, room illumination, and room temperature.
As may be appreciated from the above description, GUI 700 allows a user of computing device 100 to essentially control any appliance of any type or any appliance set, once paired with the appliance or appliances, without having to move through a number of screens and menus. It may be further appreciated that GUI 700 may be used to control discovery and pairing of computing device 100 with appliances and appliance sets whose codes and other discovery and pairing data have been downloaded from appliance data server 111, or which have been manually input by the user. It may be further appreciated that GUI 700 may allow a user to add and/or to edit any one of the levels by adding and/or removing selector buttons which may be associated with any one of the appliance types or appliance sets, appliances, panels, and elements.
It may be appreciated that GUI 700 may not be limited to including the selector buttons previously described and that it may include many other types of selector buttons which may functionally support the operation of computing device 100 as a universal remote controller. For example, some of these selector buttons may include communication selector buttons to select Wi-Fi communications, IR communications, and other RF communications (e.g. Bluetooth). Other types of selector buttons in GUI 700 may include ON/OFF selector buttons, Return Home selector buttons, Settings buttons, among many other selector buttons whose functionality are known in the art and which the skilled person may readily appreciate may contribute to the functionality of the computing device as a remote control device.
Reference is now made to FIG. 8 which schematically illustrates an exemplary general remote control screen 800 in GUI 700 for a remote controller for an appliance, according to an embodiment of the present invention. GUI 700 may be implemented in display 120 which may include display screen 148 which may display data associated with selection of any of the selector buttons 704, 706, 708.
