Abstract: A warming blanket includes a metalized fabric exterior layer and an interior heating element made of a carbon fiber or carbon veil. The warming blanket has two oppositely disposed electrodes. The carbon veil includes a central portion positioned between two oppositely disposed margin areas. A temperature sensor is positioned upon the central portion of the heating element. The warming blanket also has an electrical connector having a hub connector including a pair of spaced apart side guide rails and a guide flange. The electrical connector also has a hub assembly removably coupled to the hub connector. The hub assembly has a mounting tongue being sized and shaped to fit between the spaced part side guide rails and between the second portion of the guide flange and the mounting plate. The hub connector and hum assembly have mating electrical snaps.

Abstract: A passive, non-invasive, non-contacting apparatus and method for monitoring the respiration of a subject within a monitored environment is disclosed. The apparatus generally comprises a pair of sensors which detect changes in infrared energy. The first sensor detects changes in infrared energy which signifies and corresponds to changes in the monitored environments of a component to be monitored and generates a first signal. The second sensor detects changes in infrared energy which signifies reference infrared energy in the monitored environment and generates a second signal. A processing system converts the first and second signals into a third signal which signifies the concentration of the monitored component in the monitored environment. The monitored components may be CO.sub.2 H.sub.2 O or a constituent of exhaled breath such as a ketone, amino acid, insulin or pintane. In another embodiment of the invention changes in blood pH may be monitored by adding an additional sensor.

Abstract: A system for transmitting low frequency analog signals over AC power lines using FM modulation. A low frequency analog signal to be transmitted is first applied to a voltage-to-frequency converter where it is converted to a signal whose frequency varies in proportion to the analog signal amplitude. This signal is then used to modulate the carrier frequency of an FM transmitter coupled to an AC power line. The modulation signal frequency range in selected to be within the response band of the FM transmitter. The FM modulated carrier signal is received by an FM receiver coupled to the AC power line, demodulated and the demodulated signal frequency is converted by a frequency-to-voltage converter back to the form of the original low frequency analog input signal.
