    • A vehicle operated remote control access system (C) for obtaining access to a controlled environment using the headlight system (32) of a vehicle having a high beam operation and a low beam operation. The remote control access system (C) comprises a switching sensor circuit (44, 52, 50, 48, 56) for detecting a sequence of switching from a low beam to a high beam operation or from a high beam to a low beam operation of the vehicle. Two or more of these switching sequences may be employed in the present invention. A timing means (62) is provided with the circuit (44, 52, 50, 48, 56) in order to determine if a switching sequence from a low beam operation and then from a high beam operation back to a low beam operation, and possibly with a second sequence of back to high beam and then low beam operation, occurred within a predetermined time interval. If the one or more required switching sequence did occur in this time interval, then the remote control system (C) is energized to open a gate or a door. If the switching from the low beam to the high beam and back to the low beam did not occur within the predetermined time interval then no energization of the remote control system (C) will occur and the system resets to neutral.
    • 一种车辆操作的遥控接入系统(C),用于使用具有远光操作和远光操作的车辆的前照灯系统(32)来获得对受控环境的访问。 遥控接入系统(C)包括用于检测从低光束到远光灯操作或从远光灯操作到远光束操作的顺序的切换传感器电路(44,52,50,48,56) 机动车。 这些切换序列中的两个或更多个可以用于本发明。 定时装置(62)设置有电路(44,45,50,48,56),以便确定来自低光束操作然后从远光操作转换到低光束操作的切换序列,以及 可能在预定时间间隔内发生第二次返回到远光束,然后是低光束操作。 如果在该时间间隔内确实发生了一个或多个所需的切换顺序,则遥控系统(C)通电以打开门或门。 如果在预定时间间隔内没有发生从近光束切换到远光束并返回到远光束,则不会发生远程控制系统(C)的通电,并且系统复位到空档。

    • The system includes first and second LC circuits (34, 36 and 38, 40) disposed within the tire and interconnected by a diode multiplier (42) in series with a pressure switch (22). An exciter (40) establishes an energetic electromagnetic field of a first frequency such that a first LC circuit (34, 36) is resonant at the same first frequency. This first frequency is converted into energy of a second frequency by a harmonic multiplier diode (42) and is impressed upon a second LC circuit (38, 40) which is resonant at the second frequency, the second frequency being either an even or odd harmonic of the first (exciting) frequency. A receiver (26) tuned to the second frequency interrogates the second LC circuit (38, 40) for presence of harmonic energy at the second frequency. A pressure switch (22) opens when the tire pressure falls below a predetermined pressure which prevents activation of the second LC circuit (38, 40) so that the receiver (26) will not sense the second frequency to which the second LC circuit (38, 40) is resonant, in which case there is provided an indication that the tire pressure is below the desired pressure. A scanner (48) scans the receiver successively from one tire to another of the vehicle.
