Abstract: A patient interface comprises a plenum chamber and a valve, or a plurality of valves. Each valve is in fluid communication with the plenum chamber. Each valve comprises a valve member and a valve seat portion. The valve member is biased away from the seat portion and is configured to close when a pressure within the plenum chamber exceeds a predetermined valve closing pressure.

Abstract: A low power detector circuit consists of the basic four MOS transistors of an MOS flip-flop and includes another pair of MOS transistors as well as voltage equalization circuitry. The added pair of transistors and the cross coupling of the gates of two of the other transistors results in a detector circuit which automatically limits power dissipation at least by the time the proper output signal levels are attained.

Abstract: A 1,024 bit semiconductor memory system, fabricated on a single integrated circuit chip, utilizes dynamic memory cells and low power dynamic control circuitry. An initial input control signal activates the control circuitry which internally generates all the control signals. The timing of all the internally generated control signals is automatically maintained by the control circuits.
