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.

Claims

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 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 configured to store configuration information; and

a third module for outputting the alert indicating the detected environmental condition.

2. The sensor system of claim 1, wherein the first amount of power is smaller than the second amount of power.

3. The sensor system of claim 1, wherein the alert signal includes an identifier associated with the first module.

4. The sensor system of claim 1, wherein the alert signal indicates a level of the detected environmental condition.

5. The sensor system of claim 1, wherein the first event is a measure of the environmental condition surpassing a threshold.

6. The sensor system of claim 1, wherein the first module detects a plurality of environmental conditions.

7. A method for outputting an alert, comprising:

receiving configuration information for allowing adaptation to detect an environmental condition;

storing the received configuration information;

detecting the environmental condition at a first module operating in a first mode;

outputting, at the first module, a signal indicating the detected environmental condition in a second mode, the first module transitioning from the first mode to the second mode after occurrence of a first event;

providing a first amount of power to the first module in the first mode;

providing a second amount of power to the first module in the second mode, the second amount of power provided to the first module after occurrence of the first event; and

outputting the alert indicating the detected environmental condition.

8. The method of claim 7, wherein the first amount of power is smaller than the second amount of power.

9. The method of claim 7, wherein the alert signal includes an identifier associated with the first module.

10. The method of claim 7, wherein the alert signal indicates a level of the detected environmental condition.

11. The method of claim 7, wherein the first event is a measure of the environmental condition surpassing a threshold.

12. The method of claim 7, wherein the first module detects a plurality of environmental conditions.
