Abstract: A HVAC assembly includes a temperature mixing valve that comprises a shaft, an upper paddle, a lower paddle, and a yielding means. The upper paddle and the lower paddle attach to the shaft. The yielding means applies a force to keep the upper paddle sealed to prevent cold air in a cold air inlet from entering a mixing zone and the lower paddle moves away from a shared sealing boundary over a predetermined angle of rotation before the upper paddle initially moves to allow cold air to enter the mixing zone. Movement of the lower paddle away from the shared sealing boundary allows cold air to enter a hot air inlet and admix with hot air to mix in the mixing zone to produce non-stratified air.

Abstract: A shorting clip terminal connector assembly electrically shorts together terminals in a first connector body dependent on connection status of a first and a second connector body. A shorting clip terminal disposed in a shorting clip terminal cavity in the first connector body receives a protrusion disposed on the second connector body. When the second connector body is mated with the first connector body, the protrusion engages a lift element of the shorting clip terminal in the shorting clip terminal cavity thereon and urges the lift element to lift contact elements of the shorting clip terminal away from the terminals in the shorting clip terminal cavity enabling insertion of protrusion side walls intermediate the contact elements and the terminals in the shorting clip terminal cavity. The contact elements of the shorting clip terminal do not make electrical contact with the terminals and the protrusion side walls further shield the contact elements from making electrical contact with the terminals.

A power level of the transmitted signal is determined during the predetermined period of time that corresponds to the predetermined time intervals, and the controller commands the switching device to switch to an antenna element based upon the determined power level.

Abstract: An occupant detection system emits an ultrasonic signal for detecting the presence of an occupant by reflecting the signal off the occupant and then determines that an occupant is present by detecting motion of the occupant. One type of motion that is detected is the small rhythmic motion associated with respiration. The motion detection system improves detection of motion smaller than a wavelength of the ultrasonic signal by shifting the wavelength of the ultrasonic signal to increase the detected motion signal. The system may also determine the presence of an occupant by comparing the motion signal to a motion pattern that corresponds to respiration.
