Description of original award (Fiscal Year 2007, $450,294)

The goal of this effort is to develop an automated standoff detection technology to assist both medical and correctional personnel in identifying physiological changes in an individual directly associated with asphyxia. Monitoring and detection system for prisoner suicide consisting of an optimized range-gated radar with adaptive learning and classification algorithms.
The majority of the users of this technology will be corrections and medical personel.

The deliverable to the government does not include a working system, only a report and a demonstration. Demonstration of a motion sensing system prototype that is capable of capturing respiration and breathing, raw data and results for the NIH Data Resource Program, and a final report summarizing the design effort, system architecture, and future work.

The majority of the users of this technology will be local law enforcement.


This award will provide funding for General electric to continue development and situational testing of an automated suicide warning system in a correctional facility. This technology uses radar to monitor an individual's repiratory and cardiopulmonary activity without skin contact, through analysis of the movement of the individual's torso. Successful development of this technology will increase the capability and effectiveness of the corrections community.
