Abstract: A tracking detector device for use in a free-space optics (FSO) system includes a position sensor and an optical receiver coupled to the bottom surface of the position sensor. The position sensor has an optical aperture configured to allow a portion of incoming light to pass through the position sensor and a plurality of position receivers located adjacent to the optical aperture and configured to sense portions of the incoming light. The tracking detector device may also include a focusing optic disposed adjacent to the bottom surface of the position sensor and configured to focus the portion of the incoming light that passed through the position sensor onto the optical receiver. The tracking detector may advantageously be employed in FSO communications systems and provide fully automated alignment with an incoming light beam under computer control.

Abstract: The present invention is a corpsman/medic medical assistant system that includes a portable transmit/receive pack, sensor leads for first and second physiological sensor subsystems and a corpsman/medic medical assistant control unit that includes a wireless transceiver. The portable transmit/receive pack has a sealed housing that includes the first and second physiological sensor subsystems, at least one processor running at least one algorithm, a wireless transceiver, and memory with a front panel that includes a display, at least one event key, a treatment button for recording treatment data, a timer, an observation button for recording observation data, and a plurality of physiological trend indicators. The algorithm determines a current physiological trend status of the patient based on the plurality of physiological measurements, and the transmit/receive pack links to the control unit by the wireless transceiver and receives the current physiological trend status of the patient.
