Abstract: A sensor power management arrangement includes a signal processing circuit configured to receive signal from a sensor, to test the signal against at least one criterion, and to pass the signal for further processing in response to the signal passing the at least one criterion. In this way, only signals that are of a sufficient importance or significance will consume the maximum amount of processing energy and through processing by later processes or circuitry. Should a signal from a sensor not be strong enough or meet other criteria, power will not be wasted in preparing that signal for provision to the microcontroller or microprocessor. Additional flexibility in the sensor power management can be realized by adjusting the criteria against which the sensor signal is compared based on a status of the sensor apparatus.
Abstract translation: 传感器电源管理装置包括信号处理电路，其被配置为从传感器接收信号，以针对至少一个准则测试信号，并且响应于通过所述至少一个准则的信号而传递用于进一步处理的信号。 以这种方式，仅具有足够重要性或重要性的信号将消耗最大量的处理能量并且通过后续处理或电路的处理。 如果来自传感器的信号不够牢固或符合其他标准，则在准备将信号提供给微控制器或微处理器时，功率不会被浪费。 基于传感器装置的状态，可以通过调整传感器信号进行比较的标准来实现传感器功率管理中的额外的灵活性。
