Remote biological, chemical and explosive detector
First Claim
1. A remote detector, comprising:
- a substrate member;
a reactive material disposed on the substrate, the reactive material selected to change an optical property in the presence of a target agent;
a camera positioned to receive electro-magnetic radiation from the reactive material and to generate image data that is indicative of the change in the optical property;
a processor coupled to the camera and configure to receive the image data and generate a processed signal;
a radio frequency (RF) transmitter coupled to the processor and configured to wirelessly transmit the processed signal to a base station; and
a radio frequency (RF) receiver configured to receive remote commands from the base station.

Abstract
A distributed detector system is provided for remotely detecting agents indicating the presence of particular biological, explosive, or chemical targets. The distributed detector system may be used for security threat detection, manufacturing or environmental monitoring, or medical assaying. In the detection system, a central server or base station wirelessly communicates with a set of distributed detectors. In this way, the central server or base station is able to aggregate detection information, as well as apply additional processing and analysis to data collected at the detectors. Each detector has a reactive material, such as a silicon-polymer, that changes an optical property in the presence of a target agent. A camera is positioned to take images of the reactive material from time to time, and has local processing to determine when the reactive material has likely changed. In some cases, the detector may have sufficient processing power to classify the change according to its urgency or threat level. The detector wirelessly communications to the central server or base station, and appropriate alerts or notifications can be generated.

11. A method of generating an alert signal, comprising;
-
receiving at a client camera device an electro-magnetic signal from a reactive material, the reactive material selected to change an optical property in the presence of a target agent; generating image data that is indicative of the change in the optical property; processing, using the client camera device, the image data to identify the change in the reactive material; classifying, using the client camera device, the change to determine presence of the target agen and to determine a threat or urgency level; and transmitting, using the client camera device, a radio frequency (RF) signal indicative of the target, threat or urgency information to a central server. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
