Abstract: A bio-information monitoring system passively monitors a patient with a remote portable bio-information unit that takes various bio-information measurements at selected time intervals as well as at random times without patient intervention. The measurements are converted to digital signals which are transmitted from the bio-information unit to a modem when the bio-information unit is in proximity to the modem. The signals are stored in the modem and uploaded to a central monitoring network. Automatic alerts may be sent from the central monitoring network to a treatment provider. The treatment provider may also access the information through secured dedicated websites via the Internet.

Abstract: An apparatus (10) for turning steerable wheels of a vehicle comprises a housing (14) that defines a fluid chamber (24). A rack bar (26) extends longitudinally through the housing (14) and is connectable with the steerable wheels of the vehicle. The rack bar (26) is movable relative to the housing (14) for turning the steerable wheels. A piston assembly (34) is fixedly attached to the rack bar (26) and sealingly engages the housing (14). The piston assembly (34) divides the fluid chamber (24) into first and second chamber portions (40 and 42). A fluid source (80) directs fluid toward one of the first and second chamber portions (40 or 42) for creating a differential pressure between the first and second chamber portions (40 and 42). The piston assembly (34) and the rack bar (26) move relative to the housing (14) in response to the differential pressure. The piston assembly (34) includes structure (132) for dampening fluid pulsations emanating from the fluid source (80).

Abstract: The invention relates to a method for forming a valve assembly for a rack and pinion steering apparatus. A pinion having a bore formed therein, a torsion bar having an outer diameter, a valve sleeve, and an input shaft are provided. The input shaft has a bore and an elongated cavity formed therein. The input shaft has an outer diameter less than an inner diameter of the valve sleeve. The torsion bar is forced into the bore of the pinion to friction weld the torsion bar to the pinion. The valve sleeve is positioned over the torsion bar and pinion, and secured with the pinion. The torsion bar is positioned within the bore of the input shaft such that a first end of the torsion bar is positioned coaxially within the elongated cavity of the input shaft. A locking material is inserted into the elongated cavity to lock the torsion bar and the input shaft together.
