摘要： A system for calibrating a blood pressure transducer and monitor combination. The transducer assembly has a calibration resistor. The monitor cable has a housing which contains a switch and a shunt resistor. Electrical connections are provided to place the calibration resistor and shunt resistor in series with each other and in shunt across one leg of a transducer bridge to produce a reading of 100 mmHg on the monitor.

摘要： A pressure transducer (10) for measuring fluid pressure in a fluid path comprising a strain gauge circuit (37) of thick film piezoresistors formed on an alumina diaphragm (36) in a Wheatstone bridge configuration. Each resistance leg of the bridge typically includes a thick film measuring piezoresistor (R1A) to which selected thick film patch-in piezoresistors (R1B, R1C, R1D, R1E) are selectively connected to create a measuring resistance network (PN1). The measuring resistance network is adjusted to a predetermined resistance value to balance and optimize the electrical symmetry of the bridge. The pressure transducer (10) includes a mechanical stop member (46) located adjacent the alumina diaphragm (36) such that the fully deflected diaphragm contacts the stop thereby physically preventing the diaphragm from deflecting an amount that would cause the diaphragm to rupture.

摘要： A color stabilized composite material combines polymers with cellulosic natural fibers or wood or wood based composite materials to manufacture an array of products for both indoor and outdoor applications. The invention provides the means to enhance the color stability of such products from the negative effects of ultraviolet radiation and weather in addition to improving the physical properties of the overall fiber-polymer matrix. In one aspect, the invention provides a composite material including a natural fiber, such as wood flour, and a polymer resin, wherein the natural fiber has been pretreated with a bleaching or oxidizing agent. In another aspect, the invention provides a color stabilized composite building material including an elongated substrate, and a thermoplastic material coating disposed on a longitudinal circumference of the substrate, which may be wood or a wood-based composite material such as plywood, cellulosic fiberboard, particle board, waferboard, flakeboard, chipboard, or oriented strand board.
