Title: Apparatus for detecting fluid line occlusion
Inventor: FUISZ RICHARD C
IPC: A61M5/168
Filed: 1990-11-01
Abstract: The apparatus and method for detecting pressure and occlusion in a fluid line is for use with a fluid line being operated upon Say a positive displacement, peristaltic pump having several cam follower fingers pressings against the fluid line sequentially to force fluid through the line peristaltically. A sensor follower finger is mounted to the cam shaft of the pump among the other peristaltic fingers in order to cyclicly press against the fluid line with a certain degree of force and displacement as the cam shaft rotates. The sensor follower finger includes a strain gauge mounted on the sensor finger to generate a signal indicating the degree of force being applied by the sensor finger against the tubing, and a signal processor unit which receives this force signal and determines the pressure within the fluid line used upon the signal. The signal processor compares the measured pressure with an upstream reference value during an upstream pressure measurement mode, and compares the measured pressure with a downstream reference value during a downstream pressure measurement mode. An alarm may also be provided for indicating if there is an occlusion condition either upstream or downstream when the measured pressure varies significantly from these reference values.

Title: High efficiency power amplifier
Inventor: ENGELMANN RUDOLPH H
IPC: H03F3/21
Filed: 1990-11-21
Abstract: ABSTRACT    A system for driving a load is disclosed comprising a programmable power supply for metering power directly to the load and a regulating element connected to the load and parallel with the programmable power supply for shunting excess power from the programmable power supply in response to a control signal in order to waveshape the power signal to the load.  Sensing means are provided for sensing the power demands of the load and generating a control signal which is received by the programmable power supply.  In response to the control signal, the programmable power supply meters more or less power to the load so that the power delivered directly to the load by the power supply approximately follows the power demand of the load as determined by the control signal.  The power delivered by the programmable power supply is always in excess of the power demanded by it so that the regulating element continuously shunts power away from the load in accordance with the control signal in order to waveshape the power signal so as to provide a high fidelity signal to the load.

Inventor: ENG JOHN E
IPC: H02M3/158
Filed: 1990-12-21
Abstract: A synchronized switching system for use in a power converter. A pulse-width modulation controller is provided to alternately turn on and off a switching device and control the on/off duty cycle. When the switching device is turned off, initial commu-tating or flyback current from an inductor is conducted by a protective diode connected to ground. The diode is paralleled by a more efficient secondary switching device that is synchronized to conduct during the nonconduction period of a main switching de-vice. A sense winding is added on the inductor for synchronizing the secondary switching device. A digital logic circuit controls the conduction time of the secondary switching device based on signals from a pulse-width modulation controller and from the sense winding of the inductor. After the main switching device has been conduct-ing for the required time, the pulse-width modulation controller turns it off. The digi-tal logic circuit senses the voltage level on the inductor and causes the secondary switching device to conduct, just after the main switching device stops conducting. The digital logic circuit prevents the main and secondary switching devices from con-ducting simultaneously.
