Abstract:
A method for configuring a transmitter device to transmit a recognized transmission to a receiving device is provided. The method includes transmitting a first transmission and transmitting a second transmission after the first transmission. The method further includes receiving, during the second transmission, a user input signal from an interface for receiving signals from one or more user interface elements. The method further includes storing an attribute associated with the second transmission in a memory device in response to the user input signal.
Abstract:
A wireless transmit-only apparatus (20) has a controller (21) that responds to a user interface 25 by correlating specific user input with a corresponding characterizing transmission parameter(s) as is stored in a memory (35) and by selecting a corresponding resonant device (31 and 32). The latter devices serve to drive the PLL control input of a phase locked loop (23) to thereby influence the transmission carrier frequency of a wireless transmitter (22). In a preferred embodiment, at least one of the resonant devices comprises a mechanically resonant device such as a surface acoustic wave device, a crystal resonator, or a ceramic resonator.
Abstract:
A universal remote control interacts with a user to assist in training to one or more appliances. If the appliance is activated by a rolling code activation signal, a sequence of different rolling code activation signals is transmitted until the user indicates a successful transmission. If the appliance is activated by a fixed code activation signal, a fixed code word is used to generate and transmit each of a sequence of different fixed code activation signals until the user indicates a successful transmission. At least one of the sequences of activation signals inserts a preset amount of time after each activation signal transmission. If user input is not received within the preset amount of time, the next activation signal in the sequence is transmitted.
Abstract:
A network operator radio module (NORM) configured to be removably attached to a barrier operator comprises a transmitting antenna, a receiving antenna, a transceiver antenna, and a microcontroller. The module communicates with a communication network that comprises various nodes configured by a network controller module and a network communication module. Each node may be associated with a network appliance, and may be remotely controlled by sending a suitable function code to the module via local command signals. Furthermore, various local remote transmitters and keyless entry transmitters are configured to transmit function codes to control the module and the associated various network appliances.
Abstract:
The present invention provides a universal remote control with components interconnected by a bus, permitting separate location of the components. During operation, a control input is received from a user. A control signal representing the control input is transmitted through the bus. The control signal is received from the bus at a location remote from where the control input was received. A radio frequency activation signal is transmitted based on the received control signal.
Abstract:
A trainable transmitter includes a receiver circuit and a control circuit. The receiver circuit is configured to receive signals. The control circuit is coupled to the receiver circuit and is configured to determine a noise level for a frequency range of the receiver circuit. The control circuit is further configured to select and provide a receiver threshold to the receiver circuit. The receiver threshold is variable based on the noise level. The trainable transmitter may be integrated in a vehicle, in particular a vehicle interior element.
Abstract:
A radio frequency transmitter is configured to send radio frequency messages to activate a remote system. Each message includes an encrypted counter value and a transmitter identifier. The transmitter is configured to send at least two of the messages having sequential encrypted counter values in response to a single user input.
Abstract:
A control unit 11 responds in ordinary course to external stimuli. In addition, the control unit 11 further processes the external stimuli to characterize and otherwise seek to identify certain aspects and attributes. Unique audible signals that correspond to varying results of such analysis are then provided. These audible signals can readily facilitate ease and accuracy when diagnosing the cause of a particular operational issue. In one embodiment the diagnostic audible signals are selectively mutable without concurrently muting other audible signals as correspond to ordinary operation of the control unit 11.
Abstract:
A system for monitoring an area and sounding an alarm comprising. The system employs one or more sensors positioned about the protected area. Each sensor has one or more pulse generators generating one or more pulses each with a preassigned pulsewidth. The sensors are connected to a controller by a single wire. The controller sounds an alarm upon receipt of one or more pulses and identifies the sensor actuating the alarm by the measured pulsewidth.
Abstract:
A remote control system for opening and closing a barrier, such as a garage door, includes an RF receiver and a plurality of RF transmitters. The transmitters and receiver include circuitry programmed to provide transmission of encrypted code signals each time the transmitters are used and employing a code hopping method which prevents unauthorized signal interception or code "grabbing". The system is operated in a code learning mode for the receiver by momentarily actuating a receiver learn mode button for receiving each transmitter identification code and a secret decryption key for that transmitter with the system automatically returning to the operate mode. Each transmitter identification and secret key code signal is automatically and randomly stored in an available and unused memory in the receiver circuitry. A multibit hopping code is transmitted from each transmitter to the receiver with each transmitter operation in the operate mode of the system and the hopping code changes with each transmission to prevent theft or code grabbing and resultant unauthorized operation of the system.
