A configuration is provided by which it may be determined whether a MEMS device is in a select state. The select state is defined by a position of a moveable element, which is moved with electrostatic forces upon activation of an electrode. The select state is detected with a sensing configuration that has first and second regions. The regions are generally separated such that they are electrically uncoupled unless the moveable element is in the position that defines the select state. A detector may be provided to indicate whether the first and second regions are coupled electrically.

A method and apparatus for protecting a conductor in an integrated circuit. A protective covering can be disposed over a conductor for a substantial length along the conductor while allowing a portion of the conductor to be exposed. The protective covering can be configured as a tunnel which runs for a substantial length along the conductor and can be operable to prevent the occurrence of electrical shorts during operation of the integrated circuit. According to one embodiment of the invention the integrated circuit can be configured as a micromachined device with active mechanical components exposed to the atmosphere.

A medical infusion pump (10) for delivering liquids to a patient includes an elastomeric pump chamber (140) contractable between a refill position and a discharge position. An inlet valve (122) is operatively associated with an elastomeric inlet (142) supplying liquid to the pump chamber (140). The inlet valve (122) is selectively positionable in an open position permitting and a closed position preventing flow of liquid between the inlet (142) and the pump chamber (142). An outlet valve (124) is operatively associated with an elastomeric outlet (144) which conveys liquid from the pump chamber (140). The outlet valve (124) is selectively positionable in an open position permitting and a closed position preventing flow of liquid between the outlet (144) and pump chamber (140). A pump motor (256) and associated plunger (120) contracts and expands the pump chamber (140) between the refill position and the discharge position. An electronic control (542) operatively associated with the pump motor (256) and plunger (120) and the inlet and outlet (122, 124) valves actuates the pump motor (256) and the inlet and outlet valves (122, 124) to drive liquid through the pump chamber (140) in a predetermined pumping cycle.

A compact and highly reliable proportioning pumping system for supplying a precise and controllable mixture of concentrate and water in a kidney dialysis machine comprises a central body and a pair of oppositely mounted pivotable linkages coupled to the body. A first pivotable linkage is coupled by connecting rods to a water metering piston and a concentrate metering piston respectively, a variable stroke ratio being provided by a signal actuated drive coupled to the linkage mechanism and controlling the relative position of the end of one of the connecting rods. The change of position is advantageously effected so as to maintain a precise proportionality between the flows delivered by each of the pistons throughout their variable stroke lengths. The range of proportioning adjustments can be mechanically limited and alarm conditions can readily be detected. Precise delivery of surge-free flows of liquid for subsequent mixing is enhanced by controlling flow through each piston with a fast-acting metering valve system.

A system for continuously removing gases from a liquid initially subjects the liquid to a pressure drop and then injects the liquid into a toroidal chamber in which it is impelled into a hollow annular flow path of high surface area and velocity. The liquid is forced helically about the annulus to create internal cavitation, and entrained and dissolved gases are removed both during injection and cavitation by a suction vent at an interior region of the toroidal flow chamber. Liquid is ejected from the periphery of the toroidal chamber into the bottom of a settling chamber, also maintained under vacuum, such that gases rise to another suction vent at the top of the chamber. Degassed liquid in the settling chamber moves under gravity into the orbit of an adjacent centrifugal pump and is continuously fed out from the system into ambient pressure by a positive drive pump. In an advantageous exemplification of the invention, a toroidal flow impeller and centrifugal pump are mounted in adjacent relation on a common magnetically driven shaft from a coaxial motor which also drives a suction pump for the system.

A number of methods and systems for overcoming stiction are provided. The systems include electro-mechanical systems capable of exerting a variety of forces upon areas prone to stiction. The systems can be MEMS arrays or other types of devices where stiction related forces occur. The methods include a variety of ways of causing movement in areas prone to stiction forces. Such movement can be vibrational in nature and is sufficient to overcome stiction, allowing a trapped element to be moved to a desired location.
