Detailed Description
Referring to the drawings in general, systems, devices, and methods for a trainable transceiver to train and control multiple commands to a single channel are shown and described. The trainable transceiver may transmit various signals to control or activate one of the functions on the remote electronic device (e.g., open or close a door). The present disclosure allows for operation of the trainable transceiver to be enabled or disabled by a locking mechanism when performing multi-factor authentication. In some embodiments, the locking mechanism may enable or disable operation of the trainable transceiver by performing two-factor authentication. In a first authentication step, the trainable transceiver may compare the input sequence on the button to a lock or unlock sequence. In a second authentication step, the trainable transceiver may compare data (e.g., images, radio frequency signals, etc.) acquired by the sensor to the validation data set. If the input sequence matches the lock or unlock sequence and the data acquired by the sensor matches the validation data set, a locking mechanism may be triggered to enable or disable operation of the trainable transceiver.
Referring generally to trainable transceivers for controlling home electronics devices and/or remote devices, home electronics devices may include the following: such as a garage door opener, light, security system, and/or other device configured to receive an activation signal and/or a control signal. The home electronics device need not be associated with a residence, but may also include devices associated with a business, government building or location, or other fixed location. The remote device may include a mobile computing device such as a cell phone, smart phone, tablet computer, laptop, other computing hardware in a vehicle, and/or other device configured to receive activation signals and/or control signals.
The activation signal may be a wired signal or preferably a wireless signal, which is transmitted to the home electronics device and/or the remote device. The activation signal may include a control signal, control data, encrypted information (e.g., a rolling code seed, a look-ahead code, a secret key, a fixed code, or other information related to encryption technology), or other information transmitted to the home electronics device and/or the remote device. The activation signal may have parameters such as one or more transmission frequencies (e.g., a channel), encrypted information (e.g., a rolling code, a fixed code, or other information related to encryption techniques), identifying information (e.g., a serial number, manufacturer, model number, or other information identifying the home electronic device, remote device, and/or other device), and/or other information related to formatting the activation signal to control a particular home electronic device and/or remote device.
The trainable transceiver may transmit and/or receive information (e.g., activation signals, control data, status information, or other information) using radio frequency signals. For example, the transceiver may transmit and/or receive radio frequency signals in the ultra high frequency range, typically between 260 and 960 megahertz (MHz), although other frequencies may be used. In other embodiments, the trainable transceiver may include additional hardware for transmitting and/or receiving signals (e.g., activation signals and/or signals for transmitting and/or receiving other information). In some embodiments, the trainable transceiver may include light sensors and/or light emitting elements, microphones and/or speakers, cellular transceivers, infrared transceivers, or other communications devices.
The trainable transceiver may be trained by a user to work with a particular remote device and/or home electronics device (e.g., a garage door opener). In some embodiments, a user may manually input control information into the trainable transceiver to configure the trainable transceiver to control the device. The trainable transceiver may also learn control information from the original transmitter. The trainable transceiver may receive a signal containing control information from an original transmitter (e.g., a remote control sold with home electronics devices) and detect the control information of the received signal. In some embodiments, the original transmitter is a transmitter produced by a manufacturer of the home electronics device, the remote device, or other device specifically for the respective device. The original transmitter may be a transmitter sold separately from the home electronics, remote device, or other device intended to work with the device. The original transmitter may be a transmitter or transceiver that is part of a retrofit kit to add functionality to an existing home electronics device, remote device, or other device. The original transmitter may be a transmitter or transceiver that is not manufactured or licensed by the manufacturer or owner of the home electronics device, remote device, or other device.
Referring to FIG. 1, a perspective view of a vehicle 100 and a garage 110 is shown in accordance with an exemplary embodiment. The vehicle 100 may be an automobile, truck, sport utility vehicle, or other vehicle. Vehicle 100 is shown including trainable transceiver unit 102. In some embodiments, trainable transceiver unit 102 may be integrated with a mirror assembly (e.g., a rear view mirror assembly) of vehicle 100. In other embodiments, trainable transceiver unit 102 may be mounted to other vehicle interior elements, such as a vehicle headliner 104, center control panel 106, visor, instrument panel, or other control unit within vehicle 100.
Trainable transceiver unit 102 is configured to communicate with a remote electronic system 112 of garage 110 or other structure. In some embodiments, the remote electronic system 112 is configured to control the operation of a garage door attached to the garage 110. In other embodiments, remote electronic system 112 may be a home lighting system, a home security system, a data network (e.g., using ASK, using OOK, using FSK, LAN, WAN, cellular, etc.), an HVAC system, or any other remote electronic system capable of receiving control signals from trainable transceiver unit 102.
Referring now to fig. 2, a block diagram of system 200 for trainable transceiver 102 is depicted in which locking mechanism 214 disables one function of trainable transceiver 102. Environment 200 may include trainable transceiver 102, remote electronic device 112, and original transmitter 216. Trainable transceiver 102 may be part of a housing such as a perimeter frame, rear housing, or other boundary associated with a rear view mirror assembly. In some embodiments, components of trainable transceiver 102 may be located within or mounted on a housing. In some embodiments, some components of trainable transceiver 102 may be located within or mounted on a housing, while other components of trainable transceiver 102 may not be located within or mounted on a housing. Trainable transceiver 102 may include a control circuit 202, three buttons 204A-204C, a display 206, sensors 208, and a power source 212. In some embodiments, the locking mechanism 214 may be part of the control circuit 202 as shown. In some embodiments, the locking mechanism 214 may be separate from but coupled to the control circuitry 202. The three buttons 204A-204C and the display 206 may form part of a user interface element 210.
To trigger locking mechanism 214 to enable or disable functions of trainable transceiver 102, a user of trainable transceiver 102 may first enter a button press sequence 218 on three buttons 204A-204C at user interface element 210 as an initial step in two-factor authentication. The control circuitry 202 may determine that the button press sequence 218 matches the lockout sequence. At this point, the control circuitry 202 may cause the sensor 208 to acquire sensor data 220 to complete the two-factor authentication. The sensor 208 may be one of a camera (e.g., visible light, infrared, ultraviolet, etc.), a microphone, and a Radio Frequency (RF) detector (e.g., Near Field Communication (NFC) detector), among others. The control circuitry 202 may then compare the sensor data 220 acquired from the sensor 208 to the verification data. The verification data may correspond to data previously read from the user (e.g., an iris image, a facial image, an RF signal frequency, etc.) to perform two-factor authentication. If acquired sensor data 220 substantially matches the verification data (e.g., 75% -100%), control circuit 202 may cause locking mechanism 214 to disable one or more functions of trainable transceiver 102. In some embodiments, locking mechanism 214 may prevent transmission of control signals from trainable transceiver 102 to remote electronic device 112 to activate one or more functions thereon.
Referring now to fig. 3, a schematic diagram 300 of trainable transceiver 102 and external devices with which trainable transceiver 102 may communicate (e.g., remote device 112 and original transmitter 216, etc.) is depicted. In brief overview, trainable transceiver 102 may include control circuitry 202 having a processor 302, memory 304, and transceiver circuitry 306, sensors 208, user interface elements 210 having one or more buttons 204A-204N and a display 206, a power source 212, and a locking mechanism 214, among other components. Remote device 112 may include control circuitry 322, memory 324, transceiver circuitry 326 for transmitting and receiving signals, sensors 328 to monitor itself, the environment, hardware, an interaction device 330 to interact with another device, and a power supply 332 for powering the components. The primary transmitter 216 may include control circuitry 334, memory 336, transceiver circuitry 338 for transmitting and receiving signals, and a power supply 340 for powering the components.
Control circuit 202 of trainable transceiver 102 may be configured to receive input from user interface 210. In response to input from user interface 210, control circuitry 202 may cause transceiver circuitry 306 to transmit activation signals, control signals, and/or other signals. The control circuitry 202 may use the information in the memory 304 in order to cause the transceiver circuitry 306 to format signals for receipt by a particular home electronic device or remote device 112. In some embodiments, the memory 304 may include an identifier of the device, encryption information, frequencies for transmission to the device, and/or other information.
Control circuitry 202 may include various types of control circuitry (digital and/or analog) and may include a microprocessor, microcontroller, Application Specific Integrated Circuit (ASIC), Graphics Processing Unit (GPU), or other circuitry configured to perform various input/output, control, analysis, and other functions as will be described herein. In other embodiments, control circuitry 202 may be a system on a chip (SoC) alone or together with additional hardware components described herein form a system on a chip (SoC). In some embodiments, the control circuitry 202 may also include memory 304 (e.g., random access memory, read only memory, flash memory, hard disk storage, flash storage, solid state drive memory, etc.). In further embodiments, the control circuit 202 may act as a controller for one or more hardware components included in the trainable transceiver. In some embodiments, the control circuitry 202 may act as a controller for a human machine interface (e.g., user interface 210) or other operator input device, a controller for a transceiver, transmitter, receiver, or other communication device (e.g., implementing a bluetooth communication protocol).
The control circuitry 202 may be coupled to a memory 304. Memory 304 may be used to facilitate the functionality of trainable transceiver 102 described herein. The memory 304 may be volatile and/or nonvolatile memory. The memory 304 may be random access memory, read only memory, flash memory, hard disk storage, flash storage, solid state drive memory, or the like. In some embodiments, control circuitry 202 may read from and write to memory 304. The memory 304 may include computer code modules, data, computer instructions, or other information that may be executed by the control circuit or otherwise facilitate the functions of the trainable transceiver described herein. Memory 304 may include encryption codes, pairing information, identification information, device registry, and the like. Memory 304 may include computer instructions, code, programs, functions, data sets, and/or other information for implementing the algorithms described herein.
The user interface 210 may include a series of buttons and illuminable signs, designs, lights or other features. Each button may be trained using one or more of the training programs described herein to operate a different home electronic device and/or remote device 112. In some embodiments, each button may be a physical mechanical button configured to trigger the control circuitry 202 to control the remote device 112 when the button is pressed or otherwise interacted with. In some embodiments, each button may be a soft key on the electronic display that is configured to trigger the control circuitry 202 to control the remote device 112 upon interaction with the soft key. The illuminable features of user interface 210 may be used to communicate information to a user of trainable transceiver 102. The user interface 210 may include a display, one or more LEDs, a speaker, and/or other output devices for providing output to a vehicle occupant. The output may convey information to a vehicle occupant regarding the location, structure, and/or designated parking area of the vehicle within the garage. In some embodiments, user interface element 210 may comprise a reconfigurable electronic display that may be touch sensitive.
In some embodiments, user interface 210 may be located remotely from one or more other components of trainable transceiver 102. In embodiments where trainable transceiver 102 is mounted in a vehicle or otherwise integrated with a vehicle, user interface 210 may be located within a cockpit of the vehicle and one or more other components of trainable transceiver 102 may be located elsewhere (e.g., in the engine compartment, in the trunk, behind or within the dashboard, in the headliner, elsewhere within the cockpit, and/or elsewhere). This may allow trainable transceiver 102 to be installed in various positions and/or orientations, including the antenna. This may allow the antenna of trainable transceiver 102 to be mounted, or otherwise located in or on the vehicle in a location that is less disturbed by vehicle structural components.
User interface 210 and other components of trainable transceiver 102 may communicate one or both ways with each other. In some embodiments, user interface 210 may communicate with the remaining components of trainable transceiver 102 via wired or wireless means. In some embodiments, user interface 210 may be connected to the remaining components of trainable transceiver 102 in a wired manner. In some embodiments, the user interface 210 may include a transceiver for transmitting signals corresponding to received inputs and for receiving status or other information to be communicated to a vehicle occupant. The user interface 210 may include a wireless transceiver (e.g., a WiFi transceiver, a bluetooth transceiver, an optical transceiver, and/or other transceiver) configured to communicate with other components using the transceiver circuitry 306 and/or a second transceiver (e.g., a WiFi transceiver, a bluetooth transceiver, an optical transceiver, and/or other transceiver) located remotely from the operator input device. Communications between trainable transceiver 102 and operator input devices may be performed using one or more wireless communication protocols (e.g., bluetooth protocol, WiFi protocol, ZigBee protocol, or other protocols). Other components of trainable transceiver 102 may communicate with operator input devices using transceiver circuit 306 and/or a second or other transceiver (e.g., a bluetooth transceiver).
Sensors 208 of the trainable transceiver may include cameras (e.g., visible light, infrared, ultraviolet, etc.), microphones, fingerprint readers, and Radio Frequency (RF) detectors (e.g., Near Field Communication (NFC) detectors), among others. Data 220 acquired by the sensor 208 may be relayed to the control circuitry 202 for additional processing. In some embodiments, data 220 acquired by sensors 208 may be used to monitor the status and other information of trainable transceiver 102 itself. In some embodiments, the data 220 acquired by the sensor 208 may be used by the control circuitry 202 to perform multi-factor authentication. Additional details regarding the functionality of the sensor 208 and the use of the data 220 acquired by the sensor 208 are detailed below.
In some embodiments, power source 212 may also be included in trainable transceiver 102. Control circuit 202 may control power supply 212 such that antenna and/or transceiver circuit 306 is provided with an amount of power determined based on the orientation of trainable transceiver 102. In one embodiment, the power source 212 may be or may include a vehicle power system. The power source may be a vehicle power system including a battery, an alternator or generator, power conditioning equipment, and/or other electrical equipment. In other embodiments, the power source 212 may include such components as batteries, capacitors, solar cells, and/or other power generation or storage devices.
Trainable transceiver 102 may be trained to an existing original transmitter 216 such that trainable transceiver 102 controls a device associated with original transmitter 216. For example, a user may set trainable transceiver 102 and original transmitter 216 such that trainable transceiver 102 is within transmission range of original transmitter 216. The user may then cause the original transmitter 216 to send an activation signal or other transmission signal (e.g., by pressing a button on the original transmitter 216). Trainable transceiver 102 may identify one or more activation signal parameters, devices, and/or other information based on the transmission signal from original transmitter 216, which trainable transceiver 102 may receive using transceiver circuit 306. The control circuitry, memory, and/or other transceiver circuitry 306 may identify, determine, and/or store information such as one or several frequencies, or channels used by the original transmitter 216 and thus devices associated with the original transmitter 216, control codes or other encryption information, carrier frequencies, bandwidths, and/or other information.
In some embodiments, remote device 112 or other device may be configured to learn identifiers, encryption information, and/or other information from trainable transceiver 102. For example, a device may be placed in a learn mode in which a user transmits a transmission from trainable transceiver 102 (e.g., by providing an input, causing the transmission). The device may receive the transmission and perform a function in response. For example, a device may send a confirmation transmission in response to receiving the transmission, send a transmission including a ready indication (e.g., the device is synchronized with trainable transceiver 102, encrypted information has been exchanged, communications have been confirmed on all channels used by the device, etc.), store an identifier of trainable transceiver 102, and/or perform other functions. This process may constitute pairing trainable transceiver 102 with remote device 112 or other device. For systems using rolling codes, trainable transceiver 102 and devices may be synchronized such that counters of trainable transceiver 102 and devices start with the same rolling code value.
Control circuit 202 of trainable transceiver 102 may include one or more modules in memory 304 and other data for performing and/or facilitating the operations and functions of trainable transceiver 102 described herein. In some embodiments, memory 304 of trainable transceiver 102 may include a training module 308, an input authenticator module 310, a lock/unlock sequence 312, a sensor verification module 314, and verification data 316, among other things. The modules of the control circuit 202 may be executed or otherwise processed or implemented using the processor 302. The processor 302 may be a general-purpose or special-purpose processor or circuitry for performing computations, processing inputs, generating outputs, and/or otherwise performing computational tasks. In some embodiments, these modules (e.g., training module 308, input authenticator module 310, sensor verification module 314, etc.) may each be a general-purpose or special-purpose processor or circuitry for executing the instructions specified therein.
The user interface 210 may include one or more buttons 204A-204N and a display 206. In some embodiments, each button 204A-204N may be a physical mechanical button (e.g., a button, a physical switch, etc.). In some embodiments, each button 204A-204N may be a touch-sensitive button on an electronic display (e.g., a screen on the vehicle console 106 or on a mirror assembly housing of the trainer transceiver 102). Pressing or interacting with the buttons 204A-204N may trigger the control circuitry 202 to perform or otherwise process the corresponding function (e.g., send a command signal to initiate a function on the remote device 112). User interface element 210 may indicate a status of trainable transceiver 102 (e.g., success or failure to perform a requested operation) via an indicator. In some embodiments, the indicator may be a light source, such as an incandescent light bulb, a laser emitting diode, or an ASCII display, among others. In some embodiments, the indicator may be an electro-acoustic transducer, such as a speaker, buzzer, or alarm, among others. In some embodiments, the indicator may be a graphical user interface element presented and displayed on the electronic display. In some embodiments, user interface 210 may be located with other components and/or modules of trainable transceiver 102. In some embodiments, user interface 210 may be located remotely from other components and/or modules of trainable transceiver 102 (e.g., at vehicle console 106, a visor, a dashboard, or other control unit within vehicle 100).
Training module 308 may include instructions, programs, executable code, and/or other information used by control circuitry 202 to perform training functions. The training module 308 may learn control information (or training information) from the original transmitter 216 to control the functions of the remote device 112. In some embodiments, upon pressing one of the buttons 204A-204N on the user interface element 210, the training module 308 may enter a training mode to learn control information or training information. The training module 308 may analyze the received control signals using one or more algorithms, look-up tables, and/or other information structures/techniques. The training module 308 may also store one or more characteristics of the control signal received from the original transmitter 216 in the memory 304. Using control signals received from original transmitter 216, training module 308 may also train trainable transceiver 102 using any number of techniques to control one or more functions of remote device 112. In some embodiments, the training module 308 may analyze or interpret the control signals from the original transmitter 216. Based on the analysis or interpretation of the control signals, the training module 308 may store the control information in the memory 304. In some embodiments, the training module 308 may identify a code type (e.g., a rolling code or a fixed code) of the control signal based on a message characteristic (e.g., a bit sequence) of the control signal. If training module 308 determines that the code type of the control signal is a rolling code, training module 308 may initiate and maintain a counter to record the rolling code count. Training module 308 may indicate the result of the training (e.g., success or failure) of trainable transceiver 102 using an indicator on user interface element 210 (e.g., using an audio and/or visual signal for the user). The training module 308 may repeat this function over multiple messages and/or signals.
To initiate the first step of two-factor authentication to enable or disable operation of trainable transceiver 102, input authenticator module 310 executing on processor 302 may determine whether input sequence 218 on one or more buttons 204A-204N matches lock/unlock sequence 312. The lock/unlock sequence 312 may specify the order in which the buttons 204A-204N are to be pressed to complete the first step of the two-factor authentication. For example, the lock/unlock sequence 312 may specify a first button 204A, then a third button 204C, then a first button 204A, and finally a second button 204B to be pressed to complete the first step of the two-factor authentication. In some embodiments, a subset of the buttons 204A-204N may be designated for the lock/unlock sequence 312. In some embodiments, lock/unlock sequence 312 may specify one order of buttons 204A-204N to be pressed to enable operation of trainable transceiver 102 and a different order of buttons 204A-204N to be pressed to disable operation of trainable transceiver 102. The lock/unlock sequence 312 may be stored as a data structure (e.g., an array, linked list, matrix, etc.) on the memory 304. In some embodiments, input authenticator module 310 may identify the mode of operation of trainable transceiver 102 in response to pressing one of buttons 204A-204N. The operating mode may be enabled or disabled. If the mode of operation is enabled, input authenticator module 310 may compare input sequence 218 to a lockout sequence for disabling trainable transceiver 102. If the mode of operation is disabled, input authenticator module 310 may compare input sequence 218 to an unlock sequence for enabling trainable transceiver 102. As such, input authenticator module 310 may use preexisting buttons 204A-204N on trainable transceiver 102 to perform a first step of two-factor authentication to enable or disable operation of trainable transceiver 102.
The input authenticator module 310 may detect a press on one of the one or more buttons 204A-204N. In some embodiments, the input authenticator module 310 may identify which button 204A-204N was pressed upon detecting each press of the button 204A-204N. The input authenticator module 310 may compare the buttons 204A-204N identified as pressed to the buttons in the lock/unlock sequence 312. In some embodiments, the input authenticator module 310 may maintain a pointer or counter on the memory 304. The input authenticator module 310 may update a pointer or increment a counter each time one or more buttons 204A-204N are pressed. Using a pointer or counter, the input authenticator module 310 may record which designated button within the lock/unlock sequence 312 is the button that was pressed, which is to be compared to the buttons 204A-204N that were identified as being pressed. Each time a button 204A-204N is pressed that matches the button specified by the lock/unlock sequence 312, the input authenticator module 310 may update a pointer or increment a counter to the next button specified by the lock/unlock sequence 312.
In some embodiments, the input authenticator module 310 may determine whether two consecutive presses on the buttons 204A-204N are within a predefined time window when comparing the input sequence 218 to the lock/unlock sequence 312. The input authenticator module 310 may maintain a timer on the memory 304 to record the time of each press of the buttons 204A-204N. In some embodiments, upon detecting the depression of one of the buttons 204A-204N, a timer maintained by the input authenticator module 310 may store the time of the detected depression of the button 204A-204N and which button 204A-204N was identified as depressed. With the timer, the input authenticator module 310 may identify the time at which the button 204A-204N is currently pressed. The input authenticator module 310 may also identify the time at which the buttons 204A-204N were previously pressed. Input authenticator module 310 may then determine the elapsed time between the current press time and the previous press time. The input authenticator module 310 may compare the elapsed time to a predefined time window. If the time elapsed between two consecutive presses is less than the predefined time window, the input authenticator module 310 may compare the button 204A-204N identified as pressed to a specified button within the lock/unlock sequence 312 identified by the pointer or counter. The input authenticator module 310 may refresh the pointer or set the counter to zero if the time elapsed between two consecutive presses is greater than or equal to a predefined time window. The input authenticator module 310 may also compare the button 204A-204N identified as pressed to the initial button specified by the lock/unlock sequence 312. As such, input authenticator module 310 may force a user of trainable transceiver 102 to enter the entire input sequence 218 within a set amount of time, thereby preventing accidental disabling or enabling of trainable transceiver 102.
If the buttons 204A-204N pressed do not match the buttons specified by lock/unlock sequence 312, input authenticator module 310 may identify the mode of operation of trainable transceiver 102. If the operating mode is identified as enabled, the input authenticator module 310 may allow the control circuit 202 to perform operations corresponding to the buttons 204A-204N identified as pressed. If the operating mode is identified as disabled, the locking mechanism 214 may prevent the control circuit 202 from performing operations corresponding to the buttons 204A-204N identified as pressed, as will be described in detail herein below. In addition, the input authenticator module 310 may reset the pointer and counter for recording which button specified by the lock/unlock sequence 312 is to be compared to the button 204A-204N identified as pressed.
If the pressed button 204A-204N matches the button specified by the lock/unlock sequence 312, the input authenticator module 310 may determine whether the button specified by the lock/unlock sequence 312 is the last button specified. In some embodiments, the input authenticator module 310 may compare the counter to the length of the lock/unlock sequence 312 to determine whether the specified button is the last button. In some embodiments, the input authenticator module 310 may determine that the pointer references the last element of the lock/unlock sequence 312 to determine whether the specified button is the last button. If the button specified by the lock/unlock sequence 312 is not the last button specified, the input authenticator module 310 may identify the next button specified by the lock/unlock sequence 312. The input authenticator module 310 may also update a pointer or increment a counter. If the button specified by the lock/unlock sequence 312 is the last button specified, the input authenticator module 310 may invoke the sensor verification module 314 to perform a second step of two-factor authentication, as described in detail herein below. In some embodiments, input authenticator module 310 may trigger locking mechanism 214 to enable or disable operation of trainable transceiver 102.
As part of the second step of two-factor authentication, a sensor verification module 314 executing on the processor 302 may obtain the data 220 from the sensor 208. In some embodiments, the sensor verification module 314 may acquire the data 220 from the sensor 208 in response to the input sequence 218 on one or more of the buttons 204A-204N matching the lock/unlock sequence 312. In some embodiments, in response to the input sequence 218 matching the lock/unlock sequence 312, the sensor verification module 314 may trigger the user interface element 210 to prompt the user (e.g., via the display 206 or an indicator) that the sensor 208 is acquiring the data 220. The acquired data 220 may come from a plurality of sensors 208 (e.g., visible spectrum camera, infrared spectrum camera, fingerprint reader, Radio Frequency (RF) sensor, etc.). In some embodiments, sensors 208 may include a camera directed at a user of trainable transceiver 102 (e.g., directed at the user's face, the user's eyes, the user's finger, etc.). In some embodiments, sensors 208 may include a fingerprint sensor to obtain a fingerprint of a user of trainable transceiver 102. In some embodiments, sensors 208 may include RF sensors to obtain RF signals from a token generator (e.g., from a key fob, smart card, laptop, smartphone, or other mobile device associated with a user of trainable transceiver 102). In some embodiments, the token generator may include a Radio Frequency Identification (RFID) element for detecting RF signals by the sensor 208. In some embodiments, the token generator may transmit the RF signal to the sensor 208 upon request (e.g., pressing a button) by a user of the token generator.
Having acquired the data 220 from the sensor 208, the sensor verification module 314 may identify the data type of the acquired data 220. The data type of the acquired data 220 may correspond to the type of sensor 208 used (e.g., camera, fingerprint reader, RF sensor, etc.). The data type of the acquired data 220 may include images, capacitance readings, or RF signals, among others. In some embodiments, the sensor verification module 314 may store the acquired data 220 onto the memory 304. In some embodiments, the sensor verification module 314 may also store the acquired data 220 on the memory 304 along with the identified data type of the acquired data 220. In some embodiments, the acquired data 220 and the identified data type may be temporarily stored and may be deleted after a predefined time window has elapsed.
The sensor verification module 314 may determine whether verification data 316 is stored on the memory 304. The verification data 316 may correspond to the same type of data as the acquired data 220 and may be used by the sensor verification module 314 as part of a second step in the two-factor authentication. Sensor verification module 314 may determine whether acquired data 220 is the first time sensor 208 acquired data 220 from a user of trainable transceiver 102. In some embodiments, the sensor verification module 314 may determine whether the acquired data 220 is the first time of the identified data type. In some embodiments, the sensor verification module 314 may maintain a counter, timer, or pointer to record the number of times or instances that the sensor 208 acquires the data 220. If the acquired data 220 is the first time, the sensor verification module 314 may set the acquired data 220 as verification data 316. Further, if the acquired data 220 is the first time of the identified data type, the sensor verification module 314 may set the acquired data 220 of the identified data type as verification data 316. Additionally, sensor verification module 314 along with input authenticator module 310 may continue to trigger locking mechanism 214 to enable or disable operation of trainable transceiver 102.
Otherwise, if the acquired data 220 is not the first time, the sensor verification module 314 may determine that the verification data 316 is already stored on the memory 304. Further, if the acquired data 220 is not the first time of the identified data type, the sensor verification module 314 may determine that verification data 316 for the identified data type is already stored on the memory 304. If it is determined that the verification data 316 is already stored on the memory 304, the sensor verification module 314 may compare the acquired data 220 with the verification data 316. In some embodiments, the sensor verification module 314 may identify the data type of the verification data 316 and the data type of the acquired data 220. If the data type of the verification data 316 matches the data type of the acquired data 220, the sensor verification module 314 may continue to compare the feature space of the acquired data 220 to the feature space of the verification data 316.
To determine the feature space of the acquired data 220 and the feature space of the verification data 316, the sensor verification module 314 may use an image recognition algorithm (e.g., object recognition or feature point recognition) on the verification data 316 and the acquired data 220. The sensor verification module 314 may also use biometric detection algorithms (e.g., facial recognition or iris recognition algorithms) on the verification data 316 and the acquired data 220. The sensor verification module 314 may also use signal processing techniques (e.g., principal component analysis, linear discriminant analysis, multi-linear subspace learning, neural networks, or other pattern recognition techniques) on the verification data 316 and the acquired data 220.
With the feature space of both the acquired data 220 and the verification data 316, the sensor verification module 314 may determine whether the data 220 acquired from the sensor 208 is substantially similar to the verification data 316. The sensor verification module 314 may calculate a difference between the feature space of the acquired data 220 and the feature space of the verification data 316. The difference value may represent a measure of the difference or distance between the acquired data 220 and the verification data 316. The sensor verification module 314 may determine whether the difference is less than a predetermined threshold. The predetermined threshold may be set such that the feature space of the acquired data 220 should be 75% -100% similar to the feature space of the verification data 316. If it is determined that the difference is less than the predetermined threshold, the sensor verification module 314 may determine that the acquired data 220 is substantially similar to the verification data 316. Sensor verification module 314 may also authenticate a user of trainable transceiver 102 as part of a two-factor authentication. The sensor verification module 314 may further display an indication of verification success (e.g., using the display 206 or an indicator) on the user interface element 210. If it is determined that the difference is greater than or equal to the predetermined threshold, the sensor verification module 314 may determine that the acquired data 220 is not substantially similar to the verification data 316. Additionally, sensor verification module 314 may deny authentication of a user of trainable transceiver 102. The sensor verification module 314 may also display an indication of authentication failure on the user interface element 210 (e.g., using the display 206 or an indicator).
Once multi-factor authentication is complete, input authenticator module 310 and/or sensor verification module 314 may identify the mode of operation of trainable transceiver 102. If the operational mode is set to enabled, the input authenticator module 310 and/or the sensor verification module 314 may set the operational mode to disabled. Input authenticator module 310 and/or sensor verification module 314 may also trigger locking mechanism 214 to disable operation of trainable transceiver 102. If the operational mode is set to disabled, the input authenticator module 310 and/or the sensor verification module 314 may set the operational mode to enabled. Input authenticator module 310 and/or sensor verification module 314 may also trigger a locking mechanism to enable operation of trainable transceiver 102.
Locking mechanism 214 may enable or disable operation of trainable transceiver 102 based on triggering instructions from input authenticator module 310 and/or sensor verification module 314. In some embodiments, the locking mechanism 214 may be a module on the memory 304 that is executable by the processor 302. In some embodiments, the locking mechanism 214 may be a separate electronic component (e.g., a multiplexer) of the control circuit 202. In some embodiments, the locking mechanism 214 may be a separate electronic component coupled to the control circuit 202. In some embodiments, locking mechanism 214 may include a mechanical switch coupled to one or more components of trainable transceiver 102. In some embodiments, the locking mechanism 214 may be controlled by the input authenticator module 310 and/or the sensor verification module 314.
In some embodiments, the locking mechanism 214 may set the operating mode to enabled or disabled based on a trigger from the input authenticator module 310 and/or the sensor verification module 314. With the mode of operation of trainable transceiver 102 set to disabled, locking mechanism 214 may limit at least a subset of the functionality of trainable transceiver 102. In some embodiments, locking mechanism 214 may disable transmission of control signals from trainable transceiver 102 to remote device 112 via transceiver circuit 306. In some embodiments, when disabling functionality of trainable transceiver 102, locking mechanism 214 may disconnect power from power source 212 to transceiver circuit 306 (e.g., using a multiplexer or mechanical switch coupled to power source 212 and transceiver circuit 306). In some embodiments, locking mechanism 214 may delete or erase training information determined by training module 308 from memory 304 when the functionality of trainable transceiver 102 is disabled. In some embodiments, when operation of trainable transceiver 102 is set to disabled, locking mechanism 214 may disable training module 308 from entering a training mode to learn control information for controlling one or more functions of remote device 112. In some embodiments, in response to the operating mode of trainable transceiver 102 being set to disabled, locking mechanism 214 may cause user interface element 210 to indicate the operating mode of trainable transceiver 102 as disabled (e.g., via display 206 or an indicator). By disabling trainable transceiver 102, locking mechanism 214 may prevent a malicious individual from activating functions of trainable transceiver 102 (either with direct physical access or remote access to trainable transceiver 102). As such, locking mechanism 214 may restrict such individuals from activating one or more functions of remote device 112 in an unsolicited or erroneous manner.
With the operating mode of trainable transceiver 102 set to enabled, locking mechanism 214 may permit all functions of trainable transceiver 102. In some embodiments, locking mechanism 214 may allow control signals to be transmitted from trainable transceiver 102 to remote device 112 through transceiver circuit 306. In some embodiments, when the functionality of trainable transceiver 102 is enabled, locking mechanism 214 may maintain or connect power from power source 212 to transceiver circuit 306 (e.g., using a multiplexer or mechanical switch coupled to power source 212 and transceiver circuit 306). In some embodiments, locking mechanism 214 may maintain training information from memory 304 determined by training module 308 while the functionality of trainable transceiver 102 is enabled. In some embodiments, when operation of trainable transceiver 102 is set to enable, locking mechanism 214 may enable training module 308 to enter a training mode to learn one or more functional control information for controlling remote device 112. In some embodiments, in response to the operating mode of trainable transceiver 102 being set to enabled, locking mechanism 214 may cause user interface element 210 to indicate the operating mode of trainable transceiver 102 as enabled (e.g., using display 206 or an indicator). By enabling trainable transceiver 102, locking mechanism 214 may allow a legitimate user of trainable transceiver 102 to regain access and activate functionality of trainable transceiver 102. Additionally, locking mechanism 214 may assist such users in controlling access when activating one or more functions of remote device 112 using trainable transceiver 102.
Referring now to fig. 4, a method 400 of enabling or disabling operation of a trainable transceiver is illustrated. Method 400 may be performed using various components and/or modules detailed herein, such as trainable transceiver 102 described in conjunction with fig. 2 and 3. In brief overview, steps 405-445 may correspond to a first step in a two-factor authentication process and steps 450-495 may correspond to a second step in the two-factor authentication process.
In more detail, at step 405, the trainable transceiver may detect a button press. Each button on the trainable transceiver may be a physical mechanical button, a touch sensitive button, or a combination thereof. Depression of a button may trigger the trainable transceiver to perform a particular function. Until no button press is detected, the trainable transceiver may repeat the functions of step 405. At step 410, upon detecting a button press, the trainable transceiver may identify the button pressed. At this point, the trainable transceiver may initiate the first step in the two-factor authentication process by comparing the button pressed to the lock/unlock sequence. The lock/unlock sequence may include a defined button sequence that enables or disables settings of the trainable transceiver. In some embodiments, there may be one sequence of push buttons to enable the trainable transceiver and another sequence of push buttons to disable the trainable transceiver.
At step 415, the trainable transceiver may determine if the elapsed time since the last button press is greater than a time limit. The time limit may limit the amount of time a user of the trainable transceiver enters a defined button sequence to enable or disable the trainable transceiver. The time limit may also prevent a user from accidentally or inadvertently enabling, disabling, or otherwise switching modes of the trainable transceiver. At step 420, if the elapsed time exceeds the time limit, the trainable transceiver may identify an initial button specified in the lock/unlock sequence. In this way, the button that checks against the lock/unlock sequence may return to the beginning of the lock/unlock sequence. At step 425, if the elapsed time is less than or equal to the time limit, the trainable transceiver may identify the current button in the lock/unlock sequence. In this way, the button checked against the lock/unlock sequence may proceed with the next one in the lock/unlock sequence. At step 430, the trainable transceiver may determine if the button pressed is in the lock/unlock sequence.
At step 435, if the button pressed does not follow the lock/unlock sequence, the trainable transceiver may determine whether the device mode is enabled. At step 440, if device mode is enabled, the trainable transceiver may perform the assigned function. At this point, the trainable transceiver may resume normal functions corresponding to the button identified as pressed. Otherwise, if the device mode is disabled, the trainable transceiver may not perform any functions. In this way, by disabling the trainable transceiver, a malicious user may be prevented from accessing functions of the trainable transceiver to activate the remote device. At step 445, if the button pressed proceeds according to the lock/unlock sequence, the trainable transceiver may determine if the button pressed is the last button in the lock/unlock sequence. If the button pressed is not the last button in the lock/unlock sequence, the trainable transceiver may repeat the functions of step 405 and 440.
At step 450, if the button pressed is the last button in the lock/unlock sequence, the trainable transceiver may acquire sensor data. The trainable transceiver may also determine that the first step of two-factor authentication has been completed. From this example, the trainable transceiver may also initiate the second final step of two-factor authentication. The sensor data may be from at least one of: cameras, fingerprint readers, and Radio Frequency (RF) sensors, among others. At step 455, the trainable transceiver may determine whether the acquired data substantially matches the validation data. The validation data may correspond to the same data type as the data acquired from the sensor. To determine whether the acquired data substantially matches the validation data, the trainable transceiver may use image recognition algorithms, biometric recognition algorithms, and other signal processing techniques, among others. In some embodiments, if the sensor is acquiring data for the first time, the trainable transceiver may set the acquired data as verification data.
At step 460, the trainable transceiver may deny authentication if the acquired data does not substantially match the verification. At step 465, the trainable transceiver may maintain the device mode. In this way, the trainable transceiver may prevent users other than legitimate users (e.g., malicious users) from gaining access to the trainable transceiver. At step 470, on the other hand, if the acquired data substantially matches the verification data, the trainable transceiver may authenticate the operator of the trainable transceiver. When the data obtained from the sensors substantially matches the verification data and the button pressed matches the lock/unlock sequence, the trainable transceiver may complete the second final step of two-factor authentication. From this point, a user of the trainable transceiver may be allowed to switch the device mode of the trainable transceiver from enabled to disabled, or vice versa.
At step 475, the trainable transceiver may identify the device mode. At step 480, the trainable transceiver may determine whether the device mode is enabled or disabled. At step 485, if the device mode is enabled, the trainable transceiver may disable operation of the trainable transceiver. When operation of the trainable transceiver is disabled, the trainable transceiver may be prevented from transmitting signals, among other functions. In some embodiments, training or control information for controlling another remote device may be erased from the memory of the trainable transceiver. At step 490, if the device mode is disabled, the trainable transceiver may enable operation of the trainable transceiver. When operation of the trainable transceiver is enabled, the trainable transceiver may be allowed to transmit signals, among other functions. In some embodiments, the trainable transceiver may be allowed to enter a training mode to relearn control or training information for controlling another remote device. At step 495, the trainable transceiver may display an indication of a device mode of the trainable transceiver.
