Sensor and transmission control circuit in adaptive interface package
DCFirst Claim
1. A sensor system for outputting an alert, comprising:
- a first module for operating in a first mode and a second mode, the first module detecting an environmental condition in the first mode, and for outputting a signal indicating the detected environmental condition in the second mode, the first module transitioning from the first mode to the second mode after occurrence of a first event;
a second module for providing a first amount of power to the first module in the first mode and a second amount of power to the first module in the second mode, the second module providing the second amount of power to the first module after occurrence of the first event;
a programmable interface moduleto 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 configured to store configuration information; and
a third module for outputting the alert indicating the detected environmental condition.

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.
