Abstract: A non-dispersive infrared gas analyzer is disclosed that accurately measures the concentration levels of a plurality of gases within a gas mixture. The analyzer includes first and second sample cells and is utilized advantageously for the measurement of NOx and hydrocarbon gas present in the exhaust of an automobile engine. The gas mixture of the exhaust is chilled before entering the first sample cell to remove a substantial amount of the water vapor from that sample cell to facilitate measurement of the NOx gas. The second sample cell receives the gas mixtue in an unchilled state to allow for accurate measurement of the hydrocarbon gas. The analyzer includes processors which are utilized to further correct the NOx measurement and which also interact with each other to provide an output data stream that is representative of the concentration levels of the gases that are being analyzed.

Abstract: An adaptor assembly is described for sampling gas in an airway tube attached to a patient. The adaptor assembly employs a filter arrangement in a subassembly which extends transversely of the axis of the patient's airway and maximizes the ratio of the effective filter area to the dead volume added by the adaptor assembly to the sampling system.

Abstract: PUMP AND ACTUATOR MECHANISM A pump is described in which a flexible enclosure defines a pump chamber and in which the contents of the pump chamber are expelled by movement of a pair of opposed pusher elements engaged with the enclosure. The pusher elements are displaced by at least one pair of beam springs, each of which is pivotally supported at one end and is engaged with one of the pusher elements at the other end. The ends of the beam springs opposite the pusher elements are pivoted by acutation of symmetrical solenoid armatures, causing each of the springs to be stressed. Relief of the spring stress forces the pusher elements toward each other. De-energization of the solenoid armatures permits the beam springs to pivot back to the original position upon filing of the pump chamber.

Abstract: IMPLANTABLE INFUSION DEVICE Multiple embodiments of an implantable infusion device for delivering precisely regulated dosages of drugs are disclosed, each device including reservoir means (16) for containing the drug, catheter means (22) for delivering the drug to the body and an actuating means (44) which is responsive to a signal applied externally of the body for initiating delivery of a precisely regulated dosage. In one embodiment, the device is implanted subcutaneously to permit actuation by a solenoid driven element responsive to coded telemetry signal applied through the skin. In additional embodiments, the reservoir is pressurized for example, by means of vapor pressure or a mechanical spring, the drug under pressure in the reservoir being released in response to an externally applied signal.
