Abstract: The present invention is directed to novel optical sensors and novel methods for sensing optical radiation. The novel optical sensors and the novel optical sensing methods are used, for example, for controlling the operation of automatic faucets and flushers. The novel sensors and flow controllers (including control electronics and valves) require only small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. A passive optical sensor includes a light detector sensitive to ambient (room) light for controlling the operation of automatic faucets or automatic bathroom flushers.

Abstract: A method and system for supplying additional hydrogen from a reservoir of stored hydrogen in a salt cavern to a hydrogen pipeline to assist in meeting customer demand for hydrogen is provided. Contaminants introduced while the stored hydrogen stream is in the salt cavern may cause the crude hydrogen stream to not have the required product purity specification. The stored hydrogen is removed from the salt cavern as a crude hydrogen stream and thereafter diluted with higher purity hydrogen formed from the pipeline to form a hydrogen product stream at or below the product purity specification. The hydrogen product can be formed without removal of any of the contaminants in the crude stream, thereby creating a more cost effective and simplified supply process compared to conventional processes employing a salt cavern for hydrogen supply.

Abstract: A device and method to constrict or occlude the lumen of a flexible tube may include an occluder under the influence of an elastic force, such as a spring force, that can compress a portion of the wall of the flexible tube. The occluder can be under the influence of the elastic force, but prevented from occluding the tube by a stop. The stop can be connected to a tube gripping feature, so that a pulling force on the tube near the gripping feature can disengage the stop from the occluder, releasing the occluder to compress the tube. In some embodiments, the pulling force applied to the tube causes movement of the gripping feature by taking up slack in a portion of the tube held in the device. In other embodiments, the pulling force applied to the tube causes the tube to stretch elastically near the gripping feature, causing the gripping feature to move, and disengaging the stop from the occluder.

The wire mesh is formed in a shape such that a diameter of the wire mesh gradually increases toward a downstream side of the introducing passage and a load exerted on the stay member when the valve element contacts the wire mesh is distributed in a diameter-increasing direction in which the diameter of the wire mesh increases.

Abstract: A breakaway coupling assembly includes a male coupling and a female coupling. The male coupling includes ribs that flex portions of the female coupling as an insert of the male coupling is positioned within the female coupling. Once the insert of male coupling is positioned into the female coupling a predefined distance, the ribs snap into a circumferential retention groove of the female coupling to secure the male coupling to the female coupling and form a fluid seal. The male coupling is decoupled from the female coupling by pinching the female coupling to release the ribs from the retention groove.

Abstract: An energy recovery ventilation system is described which allows for continuous fan speed control through pulse width modulation of direct current fans. The energy recovery ventilation described is capable of fine motor speed control without the disadvantages of high noise, low efficiency and a fixed number of speeds present in commonly-used speed-varying techniques used with alternating current (AC) fans. This may be accomplished through the use of direct current (DC) fans and pulse width modulation. A controller is used to optimize the ventilation and energy efficiency of the system through the use of several temperature sensors. The energy recovery ventilation also provides a control process for self-optimization of the energy recovery ventilation, in case the supply and exhaust airflows are unequal. An unbalance may be detected by calculating the thermal efficiencies of the exhaust and supply airflows.
