Filed:

Jul 27, 2000

Appl. No.:

09/627210

Inventors:

Jasmin B. Farshi - Northbrook IL
Steven E. Larson - Barrington IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H05H 720

US Classification:

361690, 123 4131, 165 804, 361699

Abstract:

An electronic control unit ( ) comprising a cooling module ( ) having at least one fluid channel ( ) therein, a substrate ( ) configured to define an interior region ( ) and having an electronic component ( ) mounted thereto, such that the electronic component ( ) faces the interior region ( ), and a cooling fluid ( ) within the fluid channel ( ), the cooling fluid ( ) having a temperature below an operating temperature of the electronic component ( ), wherein the cooling module ( ) is positioned within the interior region ( ), such that the heat generated by the electronic component ( ) is convectively transferred to the cooling module ( ). By integrating the cooling module ( ) with the substrate ( ) and by positioning the cooling module ( ) in the interior region ( ), the cooling module ( ) is able to convectively cool the substrate ( ).

Appl. No.:

10/805879

Inventors:

Horst Kwech - Lake Villa IL, US
Steven Larson - Palatine IL, US

International Classification:

B23B041/00

US Classification:

082001200

Abstract:

The present invention relates to an improved apparatus and method for machining pipe. In one aspect, the multifunction apparatus is an improved device for machining the inside diameter and outside diameter of pipe, as well as shaping the wall of pipe. In another aspect, the invention is an improved method for machining pipe. In particular, the method employs a one-to-one communication ratio between the geared components that control the position of the cutting tool in order to eliminate rounding errors associated with conventional gearing systems.

International Classification:

G09F 1500

US Classification:

40610

Abstract:

A collapsible sign, including a fixed frame, a plurality of sections hingedly and movably attached to the frame, the sign being movable the sections between a viewing position and a collapsed position. Adjacent pairs of the plurality of sections are positioned to provide an offset distance between axes of rotation located at each end of each section when the plurality of sections are in the viewing position.
