    • A compact antenna for use in a device for controlling the power delivered to an electric load and operable to transmit or receive radio frequency signals at a specified frequency is presented. The antenna comprises a first loop of conductive material having a capacitance and an inductance forming a circuit being resonant at the specified frequency, and a second loop of conductive material having two ends adapted to be electrically coupled to an electronic circuit. The second loop is substantially only magnetically coupled to the first loop and is electrically isolated from the first loop. In a first embodiment of the antenna, the first and second loops are formed on respective first and second printed circuit boards, which allow for a small, low-cost antenna that is easy to manufacture and maximizes efficiency. When the antenna is installed in a load control device, such as a dimmer, the first loop of the antenna is mounted on an outer surface of the device. The second loop of the antenna may be at a high-voltage potential such as line voltage.
    • 提出了一种用于控制传送到电负载并可操作以以指定频率发射或接收射频信号的功率的装置的小型天线。 该天线包括导电材料的第一环,其具有电容和形成在特定频率下谐振的电感的电感,以及具有适于电耦合到电子电路的两端的导电材料的第二环。 第二回路基本上仅与第一回路磁耦合并且与第一回路电绝缘。 在天线的第一实施例中,第一和第二环形成在相应的第一和第二印刷电路板上,这允许容易制造并且使效率最大化的小型,低成本的天线。 当天线安装在诸如调光器的负载控制装置中时,天线的第一环安装在装置的外表面上。 天线的第二回路可能处于高电压电位,例如线电压。

    • A microprocessor controlled automobile security system provides several features for enhanced operability. The system allows a receiving unit to learn a plurality of operating codes from a plurality of uniquely coded transmitters with which it can operate, thereby allowing each transmitting unit to be sold separately from each receiving unit. The system also allows for an operator to personally set the threshold at which a signal detected by a shock detector will result in an alarm being triggered. The system is further selectively operable in either a manual arming mode or a passive arming mode. The system also allows selective operation in either a full current sensing mode in which either a detected shock above an absolute threshold or a .DELTA. threshold, or current flow above a predetermined level, will trigger an alarm system or operation in a shock and current integration mode in which if a detected current exceeding a predetermined threshold and a shock above an absolute or .DELTA. threshold is required to trigger the alarm or a much greater current flow is required to trigger the alarm system.
    • 微处理器控制的汽车安全系统提供了几个增强可操作性的特征。 该系统允许接收单元从可以操作的多个唯一编码的发射机中学习多个操作码,从而允许每个发射单元与每个接收单元分开销售。 该系统还允许操作者亲自设置由震动检测器检测到的信号将导致触发报警的阈值。 系统进一步可选择性地在手动布防模式或被动布防模式中操作。 该系统还允许在完全电流感测模式中的选择性操作,其中检测到的超过绝对阈值或DELTA阈值的电流或高于预定电平的电流将触发警报系统或以冲击和电流积分模式进行的操作 如果超过预定阈值的检测电流和高于绝对或DELTA阈值的电击需要触发报警或需要大得多的电流来触发报警系统。
