Title: Pwm cycloconverter and power supply abnormality detection circuit
Inventor: ISHII SADAO
IPC: H02M5/27
Filed: 2001-03-05
Abstract: A PWM cycloconverter switches power supplies without interrupting operation if a fault occurs in a power supply. In case of trouble with a 3-phase AC power supply (1), a fault detector circuit (30) produces a signal (120) indicative of trouble, and a power switch (20) selects the output voltage from an uninterruptible power supply (10). A phase detection switch (43) selects the phase information from a phase detector (41) of the uninterruptible power supply. The phase detector (41) continues to detect the phase of the uninterruptible power supply (10) before a fault occurs in the power supply so that the exact phase information on an uninterruptible power supply (10) can be available immediately after a change of phase information from the phase detection switch (43). Therefore, operation will not be interrupted in switching power supplies.

Title: Methods for treating aneurysms
Inventor: GILMARTIN KEVIN P
IPC: A61F2/82
Filed: 2001-03-08
Abstract: This invention is directed to methods for treating aneurysms wherein the aneurysmal sac is filled with a non-particulate agent or plurality of such agents and/or with a fluid composition which solidifies in situ. Filling of the aneurysmal sac employs sufficient amount of the non-particulate agent or plurality of such agents and/or the fluid composition to inhibit blood flow into the aneurysm sac. In addition, the methods of this invention also provide for non-endogenous isolation of the parent artery proximal and distal to the aneurysmal sac from systemic blood flow of the treated mammal. The combination of these features provides for treatment of the aneurysmal sac while, at the same time, inhibiting aneurysm formation and/or regrowth in the diseased portions of the arterial wall proximal and distal to the treated aneurysm.

IPC: C07K14/14
Filed: 2003-06-02
Abstract: A family of membrane fusion proteins and polynucleotides encoding the proteins have been identified.      The proteins and polynucleotides are derived from the family Reoviridae. Two membrane fusion proteins have been isolated from reoviruses isolated from poikilothermic hosts: the p14 protein from reptilian reovirus (RRV) isolated from python, and the p22 protein from aquareovirus (AQV) isolated from salmon. The genes encoding these proteins have been cloned and sequenced. Analysis of the amino acid sequences of these proteins show that both lack the typical fusion peptide motif found in other membrane fusion proteins.      Expression of these proteins in cells results in cell-cell fusion.
