Patent CA-1313689-E (CA)
Title: Power converter with duty ratio quantization
Inventor: HENZE CHRISTOPHER P
IPC: H02M3/157
Filed: 1991-03-26
Granted: 1993-02-16
Abstract: ABSTRACT OF THE DISCLOSURE   A discrete proportional-integral-differential controller, driven from a sampling digital error amplifier, is used to generate a quantized duty ratio control signal to provide dynamic output voltage regulation for switching dc-to-dc power converters.  The sampling frequency of the digital PID controller is equal to the switching frequency of the power converter, so the digital controller may be used at different switching frequencies without recompensation.  Digital techniques are also used to provide output current limiting, soft-start, undervoltage lockout, overvoltage shutdown, and power master-clear indications.

Patent PT-1223902-E (PT)
Inventor: SUSSMAN GLENN
IPC: A61M1/00
Filed: 2000-09-12
Abstract: A surgical handpiece having two coaxial tubes or channels mounted within a body. The first tube is used for aspiration and is smaller in diameter than the second tube so as to create an annular passage between the first and second tube. The annular passage communicates with a pumping chamber formed between two electrodes. The pumping chamber works by boiling a small volume of the surgical fluid. As the fluid boils, it expands rapidly, thereby propelling the liquid downstream of the pumping chamber out of the annular passage. The distal end of the annular gap is sealed by sealing together the distal ends of the first and second tube and a plurality or orifices or ports may be formed near the seal. As the expanding gas is propelled down the annular gap, the gas/liquid stream is forced out of the distal orifices in a controlled and directed manner. The distal end of the first and second tubes may contain a bend.

Title: Immunogenic compositions comprising venezuelan equine encephalitis virus replicon vectors and paramyxovirus protein antigens
Inventor: KOVACS GERALD RAUL
IPC: C07K14/115
Filed: 2004-06-02
Abstract: Self-propagating, fusogenic blebs are produced from cells infected with a population of Venezuelan Equine Encephalitis virus replicon particles (VRP). The self-propagating, fusogenic nature of the blebs is derived from expression of heterologous genes encoding viral fusion proteins that are incorporated into the replication defective replicon particles. The resulting blebs can be harvested from supernatants of cells displaying severe cytopathic effects. The blebs are used to make immunogenic compositions and devise methods of immunizing mammals against paramyxoviruses such as parainfluenza virus type 3.
