Filed:

Jan 11, 2000

Appl. No.:

09/481454

Inventors:

Jean-Louis Fressinet - St. Jean de Touslas, FR
Alain Frugier - Tignieu, FR
David B. Greene - Lakewood CO
James Little - Bailey CO

Assignee:

Gambro Inc. - Lakewood CO

International Classification:

A61F 700

US Classification:

392470, 210232, 604 504

Abstract:

An integrated CRRT method and apparatus incorporates steps and means for compensating for heat loss from blood in an extracorporeal circuit. A blood warmer is designed to engage and hold a disposable blood tube segment to transfer heat at a closely controlled temperature to blood flowing in the disposable blood tube segment. Another significant aspect of the present invention is a blood tube segment for engagement with the blood warmer is located in downstream of a dialyzer and upstream of a venous pressure monitor, an air bubble detector and a venous line clamp. The disposable blood tube segment may be selectively connected when heat loss compensation is required and left disconnected when heat loss compensation is not required.

Appl. No.:

14/877447

Inventors:

David A. Greene - Denver CO, US

International Classification:

A24C 5/02

Abstract:

A rotating platform has a peripheral wall to form a catch basin. A donut shaped wrapper housing can hold perhaps 50-100 cigarette wrappers facing inbound with a closed end projecting out an outer wall exit hole into the catch basin. Tobacco or any work material is dropped onto the center of the rotating platform which may be motor driven. Centripetal forces urge the work material into the wrappers. Empty wrapper channels feed the excess material into the catch basin. A lid prevents loss of work material.

Assignee:

XETAWAVE, LLC - Boulder CO

International Classification:

G01R 31/00

US Classification:

32475003, 32475001

Abstract:

Apparatus, systems and methods are provided for controlling a radio frequency board on an individualized basis and with respect to one or more environmental conditions, for example, temperature, pressure, humidity. In one embodiment, an enclosure configured to hold a single board includes one or more access portals and one or more interfaces, wherein the environment within the enclosure may be modified by applying one or more environmental modifiers to the enclosure through an access portal, and the operation of the board may be modified utilizing the one or more interfaces. In another embodiment, a system for testing a plurality of boards, each in their own enclosure is provided.
