Patent number: 5455528Abstract: A first transistor is connected to a second transistor so that the first and second transistors may be initially biased in a non-conducting state when a first node is at a first voltage potential and a second node is at a second voltage potential. A potential altering circuit selectively alters the voltage potential at the first and second nodes, causes the first and second transistors to be in a conducting state for accelerating a voltage transistion at the first and second nodes toward final values, and maintains the first and second nodes at their final voltage potentials for implementing a desired Boolean function. The biasing circuit is connected to facilitate turning off the first and second transistors when the circuit is being reset for subsequent Boolean evaluations. More specifically, the biasing circuit inhibits current flow through the first and second transistors during a precharge operation to prevent excessive power consumption.Type: GrantFiled: November 15, 1993Date of Patent: October 3, 1995Assignee: Intergraph CorporationInventors: Hamid Partovi, Donald A.

Patent number: 5451207Abstract: Catheter-based coronary surgery is performed in a system which includes a combination of bypass of the heart, perfusion of the heart and the use of a therapeutic catheter to loosen plaque deposited in a coronary artery. Bypass is done with a bypass circuit circulating blood from the right atrium through an extracorporeal bypass unit and back through a femoral artery. Perfusion is done by passing a perfusate into the heart for retrograde flow, then drawing the perfusate out of the heart through a catheter which also serves as a guide for the therapeutic catheter. The open distal end of the guide is placed sufficiently close to the functional element at the end of the therapeutic catheter that plaque which has been loosened by the action of the therapeutic catheter is carried into the guide along with the perfusate, and hence out of the patient's body.Type: GrantFiled: April 25, 1994Date of Patent: September 19, 1995Assignee: The Regents of the University of CaliforniaInventor: Paul G.

Patent number: 5449461Abstract: The present invention provides a new method of pH-zone-refining countercurrent chromatography that can be operated in a manner analogous to displacement chromatography. The method uses a retainer base (acid) in the stationary phase to retain analytes in the column and a displacer acid (base) to elute the analytes in the decreasing (or increasing) order of pK.sub.a and hydrophobicity. The elution produces a train of highly concentrated rectangular solute peaks with minimum overlap. To use pH-zone refining CCC in a displacement mode, the mobile and stationary phases are switched. Thus, the original eluent becomes a retainer to retain analytes in the stationary phase, and the original retainer acid becomes a displacer to displace the analytes from the stationary phase to the mobile phase at the back of the solute bands.Type: GrantFiled: June 21, 1994Date of Patent: September 12, 1995Assignee: The United States of America as represented by the Department of Health and Human ServicesInventor: Yoichiro Ito
