Sensor and transmission control circuit in adaptive interface package

摘要

A programmable interface module includes a linear power regulator to control and provide power to interfaced components on an as needed basis. The interface module is implemented in, for example, a sensor pack and multiplexed to a plurality of sensor modules. In a first mode, the linear voltage regulator provides a relatively small amount of power which allows a sensor module to output a signal responsive to detecting an environmental condition (e.g., gamma or x-ray radiation, extreme temperatures, etc.). The interface module can switch the linear voltage regulator to a second mode in which the linear voltage regulator ramps up the amount of power provided to a detecting sensor module. The sensor module can then provide a level indicative of a concentration or intensity of the environmental condition. If the level surpasses a predetermined threshold, the senor pack can output an alert signal to security server.

1. A sensor system for outputting an alert, comprising:
a first module for outputting a signal indicating an environmental condition after occurrence of a first event; a second module for providing a first amount of power to the first module prior to occurrence of the first event and a second amount of power to the first module after occurrence of the first event; a programmable interface module to receive configuration information through wired or wireless communication, or update the configuration information, allowing adaptation to detect a particular environmental condition, wherein the programmable interface module is communicably coupled to the first module and configured to store configuration information; and a third module communicably coupled to the programmable interface module for outputting the signal indicating the environmental condition.
