ABSTRACT:
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 sensor pack can output an alert signal to security server.
