Assignee:

Rockwell Collins, Inc. - Cedar Rapids IA

International Classification:

B65H 75/48

US Classification:

242373, 267273, 267275, 267281, 267284, 267254, 267255

Abstract:

Variable tension is applied to a cord as it is drawn from a spool. More tension is applied to the cord as more cord is drawn preventing impulse stress. Cord used to attach user interface device for receiving input and presenting information.

Appl. No.:

8/789678

Inventors:

Charles P. Minning - S. Pasadena CA
Douglas W. Wolfe - La Habra Heights CA
John H. Schroeder - Redondo Beach CA

Assignee:

Raytheon Company - El Segundo CA

International Classification:

H05K 720

US Classification:

361696

Abstract:

An electronic substrate is formed of a porous planar heat exchanger and an orifice plate overlying and thermally contacting the heat exchanger. The orifice plate has a plurality of apertures therethrough. An electronic device is mounted to the orifice plate. A coolant such as air or other gas is forced through the heat exchanger and the apertures of the orifice plate to remove heat that is generated by the electronic device. Preferably, at least two of the assemblies formed of the substrate and the mounted electronic device are mounted in a facing relationship to form a multichip module. A housing is provided to support the assemblies and to channel the flow of coolant through the substrates. Electrical interconnection between the components is provided by a peripheral ring with electrically conducting paths therethrough, which ring extends between the facing substrates.

International Classification:

H01S 5/40
G02B 27/30
H01S 5/00

Abstract:

A system includes multiple laser diode modules that are spatially separated and configured to generate multiple optical beams that propagate at angles relative to each other. The system also includes an optical element having at least one entrance surface and at least one exit surface. The optical element is configured to receive the optical beams at the at least one entrance surface and output each optical beam through the at least one exit surface such that the output optical beams are closely spaced, substantially the same size, and substantially parallel to each other at a common distance downstream from the optical element, and the optical beams all share a common downstream image plane.
