US Patent:

6411109, Jun 25, 2002

Filed:

May 19, 2000

Appl. No.:

09/575343

Inventors:

Michael Hanson - Rockford IL

Assignee:

Hamilton Sundstrand Corporation - Rockford IL

International Classification:

G01R 2708

US Classification:

324691, 324522, 338309

Abstract:

A lug with relatively small resistance is provided that allows current to be determined between a source and a load by measuring the voltage drop across the lug. The voltage drop is sufficient to be above the electronic noise, and yet the resistance of the lug is low enough so that the heat produced by current flow is small compared with the heat generated by the source. The material comprising the lug is of a type and strength to be readily manufactured, and its resistivity varies by a relatively small amount with temperature.

Appl. No.:

10/980732

Inventors:

Michael Hanson - Cerritos CA, US

International Classification:

F16M 11/24

US Classification:

2481884, 2481881, 411178

Abstract:

A Furniture Leg Extension and Leveling Device and Method for Use is disclosed. The device enables the user to adjust the height of a piece of furniture, such as a bathroom vanity cabinet. The device and method involves adding an extension member to each of the legs of the cabinet. The device attaches with a single custom bolt that threads into a threaded insert that is screwed into a bore cut into the bottom of the legs. The device further includes a leveling foot for accomplishing fine adjustment to leg height to account for minute floor surface irregularities. The custom bolt used for attaching the extension member has a threaded post at one end and a threaded bore formed at its other end.

Assignee:

Sundstrand Corporation - Rockford IL

International Classification:

H02P 146

US Classification:

318716

Abstract:

A control for operating an electromagnetic machine in a starting mode of operation detects a magnitude of a parameter of power applied to an armature winding of the electromagnetic machine relative to a stationary frame of reference and converts the detected parameter magnitude into field and torque producing components relative to a rotating frame of reference. A power source coupled to the armature winding is controlled during operation in the starting mode such that a rotor of the machine is accelerated.
