    • 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.
    • 远程设备激活可以通过在具有不同特性的射频传输方案之间进行中继来实现。 无线电接收机接收用于控制设备的射频控制信号。 每个现有的射频发射机被专门设计成向无线电接收机发送具有接收机特性的无线射频控制信号。 新的无线射频发射机具有发射机特性,其中至少一个与接收机特性不同。 无线电继电器从现有发射机之一学习接收机特性,并从新发射机学习至少一个发射机特性。 然后,当从新的发射机接收到设备射频激活命令时,无线电中继器发送具有所学习的接收机特性的新的射频设备激活命令。

    • 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.

    • 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.
    • 用于打开和关闭屏障的遥控系统,例如车库门,包括RF接收器和多个RF发射器。 发射机和接收机包括被编程为在每次使用发射机时提供加密代码信号的传输并采用防止未经授权的信号拦截或代码“抓取”的跳码方法的电路。 系统以接收机的代码学习模式操作,通过立即启动用于接收每个发射机识别码的接收机学习模式按钮和用于该发射机的秘密解密密钥,系统自动返回到操作模式。 每个发射机识别和秘密密钥码信号自动随机存储在接收机电路中的可用和未使用的存储器中。 通过系统的操作模式中的每个发射机操作,从每个发射机向接收机发射多比特跳码,并且跳频码随着每次发射而改变,以防止窃取或代码抓取并导致系统的未经授权的操作。
