Abstract: An ultrasonic occupant detection and classification system transmits an ultrasonic signal and receives a composite signal containing interference created between the transmitted ultrasonic signal and a reflection of that signal from a moving occupant. A signal component of the received, composite signal is extracted by amplitude demodulation and bandpass filtered to derive a frequency characteristic that is compared to stored frequency data; and the derived and stored data are compared to identify frequencies characteristic of respiration and/or other movements characteristic of living beings.

Abstract: An arc quenching electrical connector has a male pin terminal which inserts longitudinally into a receptacle or terminal having a gassing wall engaged concentrically about the receptacle. During “hot unplugging” of the electrical connector, an arc is carried between a tip of the male pin and a contact surface of a leading end of the receptacle. The gassing wall extends over and is directly engaged to a portion of the contact surface. Because the gassing wall is also preferably an electrical insulator, the arc communicates electrically with the exposed contact surface and is biased directly against the gassing wall. The gassing wall, when heated by the adjacent arc, quenches or reduces the energy of the arc by releasing gas which eliminates arc erosion of the terminals.
