Filed:

Jun 14, 1993

Appl. No.:

8/077754

Inventors:

Richard W. Grabenkort - Barrington IL
Thomas P. Joyce - Libertyville IL

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

A61J 105

US Classification:

604408

Abstract:

A flexible container for medical solutions is provided that includes first and second film sheets sealed together along multiple sides so as to form a pouch having an open end. An end port member is located between and sealed to the first and second film sheets near the open end of the pouch to enclose the interior of the container. The end port member has at least one integrally-formed access port for fluid communication between the exterior and the interior of the flexible container. A portion of the first and second film sheets extend beyond the end port member and are sealed together along the edges of the extended portions so as to form a protective cover for the access ports. The protective cover is detachable.

Assignee:

Hamilton Sundstrand Corporation - Charlotte NC

International Classification:

H02H 7/22
H02H 1/00
H01H 47/22

Abstract:

A method includes detecting a failure in a contactor economizer that is configured to provide a first current to a coil of a contactor to close the contactor, and to provide a second current lower than the first current to the coil after the contactor is closed to hold the contactor closed. The method includes at least one of: driving contactor actuation based on economizer failure status; and/or signaling failure of the economizer through built in test (BIT) indication.

International Classification:

H02K 19/36
H02K 19/12

Abstract:

A system including a generator and a controller. The generator includes a permanent magnet generator (PMG), and an exciter. The controller manages operations of the generator. The controller includes an alternating current to direct current (AC-to-DC) converter that generates a direct current (DC) voltage, an exciter drive that provides a DC current to the exciter of the generator using the DC voltage created by the AC-to-DC converter in accordance with the control signal, and a regulator controller that drives the active AC-to-DC converter.
