Title: Method and system for determination of the pressure-volume relationship of the heart
Inventor: SHOSHAN OFER
IPC: A61B5/0205
Filed: 1996-10-04
Abstract: The present invention measures cardiac power and power increase under stress, thus calculating contractile reserve (CR), the difference between cardiac peak power and cardiac power at rest by connecting a person to an electrocardiograph and determining the pressure-volume loop (PVL) of a patient's heart. While deflating an inflated cuff on the person's arm at a controlled rate, a series of data points from peak systolic to diastolic pressure is obtained, each point consisting of cuff pressure at penetration coupled with the time of its occurrence after the corresponding ORS complex; a curve-fitting procedure is applied to turn said data points into a pressure curve resembling the ascending limb of the aortic pressure wave. The end systolic pressure (ESP) is calculated using the expression ESP = DP + 2/3 (PSP - DP), where DP = diastolic pressure and PSP = peak systolic pressure. The volume at point ESP is calculated by integrating said flow curve throughout the ejection phase of the patient's heart.

Title: Method for winding a field assembly for a universal motor and apparatus produced thereby
Inventor: METZGER JAMES I JR
IPC: H02K15/095
Filed: 1998-05-12
Abstract: A method for winding a field assembly for a universal motor and apparatus produced thereby is disclosed. The method involves winding both a field winding and a brake winding over different field poles within a field core simultaneously. After the first field winding and the first brake winding are wound, the field core is indexed to allow a second brake winding to be wound over the first field winding, and a second field winding to be wound over the first brake winding. By using the disclosed method, a field assembly is produced in which both field windings and the brake windings are wound using one continuous wire for each. Moreover, the presented method can be performed on a single winding machine.

Abstract: A squib connector socket assembly (20) for automotive air bags includes a shorting clip assembly (14). The squib connector socket assembly holds a pair of igniter pins (22) of a squib assembly which are connectable to a pair of terminals in a squib connector which plugs into the socket assembly. To prevent accidental firing when the squib connector is removed, the igniter pins are shorted by a shorting clip (18) having a pair of resilient, bowed beams which are independently biased into contact with the pins. The shorting clip is fixedly retained within a plastic socket insert. The socket insert (16) and squib assembly are assembled within a metal socket which is roll crimped about the insert and squib assembly to form an inseparable, integral squib connector socket assembly.
