Abstract:
Remote appliance activation can be achieved by relaying between radio frequency transmission schemes having different characteristics. A radio receiver receives radio frequency control signals for controlling the appliance. Each existing radio frequency transmitter is specifically designed to transmit wireless radio frequency control signals having receiver characteristics to the radio receiver. A new wireless radio frequency transmitter has transmitter characteristics, at least one of which is different from receiver characteristics. A radio relay learns the receiver characteristics from one of the existing transmitters and learns at least one transmitter characteristic from the new transmitter. Then, when an appliance radio frequency activation command is received from the new transmitter, the radio relay transmits a new radio frequency appliance activation command having the learned receiver characteristics.
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 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 rolling code 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 fixed code transmission. In response to an activation input, an activation signal is generated and transmitted based on data stored following user indication of a successful transmission.
Abstract:
A wireless transmit-only apparatus (20) can be comprised of a controller (21) that selectively controls which of a plurality of resonant devices (24 and 25) are utilized to influence the transmission carrier frequency of a transmitter (26). In a preferred embodiment at least one of the resonant devices comprises a mechanically resonant device (24) such as a surface acoustic wave device, a crystal resonator, or a ceramic resonator. In a preferred embodiment, a user interface (22) includes a plurality of independently assertable inputs. The controller responds to assertion of one of this inputs by selecting a particular set of characterizing transmission parameters (as are stored, for example, in a memory (23) and using those characterizing transmission parameters to transmit a message using a transmission carrier frequency as corresponds to use of a co-selected resonant device.
Abstract:
A security system for control access of multiple users to a selected area combines rotating electronic security code or equivalent technology with an automatic self-learning receiver. The first transmitter is “learned” by the receiver manually, but subsequent transmitters are learned without the need for actuating the conventional “manual learn” mode of the receiver. Instead, by simply sending the transmit signal twice within a fixed time period, users of the subsequent transmitters use “self-learning” circuitry (interposed between conventional transmitter and receiver technology) in a way that is relatively transparent to the user. Other aspects of conventional systems are provided, such as separate control via computer or otherwise of an authorized list of uniquely-identified transmitters. In alternative embodiments, even the first transmitter/controller can be programmed into the receiver (such as at the time of manufacturing or installing the system).

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 nullgrabbingnull. 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.
