摘要： A technique for controlling a switching circuit, such as a relay, includes one or more sensing circuits that generate signals based upon the presence of an actuating object and upon a randomly applied strobe signal. The generated signals are sampled and are used as a basis for determining the state of an output signal. The sensing circuit may generate the signals based upon capacitive coupling with the actuating object. The randomization of the sampling provides enhanced immunity to periodic or cyclic noise. Where more than one sensing circuit is included, the output of the circuits may be considered together for determining the state of the output signal, such as based upon predetermined ranges of signal levels. Signals of the sensing circuit may be sampled in the absence of the strobe to provide an indication of the relative noise level. If the noise level is determined to be elevated, the output signal may not change states.
摘要翻译：用于控制诸如继电器的开关电路的技术包括一个或多个感测电路，其基于执行对象的存在以及随机应用的选通信号产生信号。产生的信号被采样，并被用作确定输出信号的状态的基础。感测电路可以基于与致动对象的电容耦合来产生信号。采样的随机化提供了对周期性或循环噪声的增强的抗扰性。在包括多于一个感测电路的情况下，可以一起考虑电路的输出以确定输出信号的状态，例如基于预定的信号电平范围。感测电路的信号可以在没有选通信号的情况下进行采样，以提供相对噪声电平的指示。如果确定噪声电平升高，则输出信号可能不会改变状态。

摘要： A technique is disclosed for determining inductive and resistive components of power line impedance. A measurement circuit switches a burden or drain resistor between power line conductors to cause a droop or sag in a voltage waveform. The voltage waveform is sampled prior to inclusion of the resistor in the circuit, as well as after to identify the droop. The short circuit between the power lines is then removed by opening the circuit and a capacitor in the test circuitry causes a resonant ring due to the inductive component of the power line impedance. Based upon the period or frequency of the resonant ring, and upon the voltage measurements with and without the resistor in the circuit, the inductive and resistive components of power line impedance can be computed.

摘要： A drive circuit for delivering high-level power to a load, and method of stopping a high power load from operating, are disclosed. The drive circuit includes a high power circuit capable of being coupled to the load and delivering the high level power thereto, and a low power circuit that controls the high power circuit. The low power circuit includes a first circuit portion that provides at least one control signal that is at least indirectly communicated to the high power circuit and that controls the delivering of the high level power by the high power circuit, and a second circuit portions coupled to the first circuit portion. The second circuit portion is capable of disabling the first circuit portion so that the at least one control signal avoids taking on values that would result in the high power circuit delivering the high level power to the load.
