Filed:

Jun 14, 2005

Appl. No.:

11/152629

Inventors:

Arthur F. Lange - Sunnyvale CA, US
Keith Kennedy - Loveland CO, US
Mark Gibson - Portland OR, US

Assignee:

Trimble Navigation Limited - Sunnyvale CA

International Classification:

B62D 5/04
G06F 19/00

US Classification:

701 41, 280443

Abstract:

Embodiments of the present invention recite a method and system for controlling steering dead band in a mobile machine. In one embodiment, a first dead band value for actuating a steering mechanism in a first direction is determined. Then, a second dead band value for actuating the steering mechanism in a second direction is determined. The first dead band value and the second dead band value are then stored as discrete values.

International Classification:

G06F 9/30

US Classification:

712208, 712E09028

Abstract:

A microprocessor is provided that has a datapath that is split into upper and lower portions. The microprocessor includes a centralized crossbar switch module having a single data movement module. The data movement module is capable of processing instructions that require operands to be exchanged between upper and lower 64-bit halves of the split architecture. The data movement module can access and process all instructions that require simultaneous access to the entire register contents of the upper and lower portions. The data movement module is configured to execute any one of a number of different instructions to perform data manipulation with respect to one or more “split-operands” (also referred to simply as “operands” herein). The data movement module can exchange data (bytes and/or bits) of operands for the upper and lower 64-bit halves so that bytes and/or bits of operands can be moved or rearranged to other positions during execution of a particular instruction. The data movement module can allow for various types of operand data movement/manipulation that may be required to implement instruction processing that may be required per various instructions, such as permute, pack, shuffle, vectored conditional move, extract, shift, rotate instructions, any other instruction in which operand data is manipulated, shifted, moved, re-ordered, shuffled or scrambled.

Filed:

Sep 8, 1980

Appl. No.:

6/184957

Inventors:

James O. Gibson - Pacific Palisades CA
Mark G. Gibson - Pacific Palisades CA

International Classification:

C01B 3130

US Classification:

423439

Abstract:

An apparatus and process are disclosed for utilizing solar radiation and the energy contained therein for the carbothermic reduction of a metal oxide to a metal carbide. The apparatus comprises a reflective surface which collects and focuses solar radiation onto a focal mirror which consequentially reflects and focuses the solar light rays into a reaction chamber through a Fresnel lens and a transparent window provided on the chamber. The solar light rays are focused by the reflective surface focal mirror and Fresnel lens such that the energy absorbed by reactants in the reaction chamber is sufficient for the carbothermic reduction of the metal oxide.

Inventors:

James O. Gibson - Pacific Palisades CA
Mark G. Gibson - Pacific Palisades CA

International Classification:

B05D 302

US Classification:

427228

Abstract:

Carbon fiber reinforced tantalum carbide composites are produced by vacuum infiltration of omni-weave carbon, e. g. three dimensional graphite, yarn preforms with an aqueous saturated solution containing tantalum fluoride and sucrose. Anhydrous ammonia is added under pressure, forming ammonium fluoride, which is removed by vacuum sublimation by application of heat. The resulting preform containing tantalum pentoxide and partially pyrolyzed sucrose is heated at high temperature and reduced pressure to decompose the sucrose to yield active carbon which reacts with the tantalum pentoxide to yield tantalum carbide and carbon monoxide. After repeated multiple infiltrations and processing, a composite is produced having a matrix of tantalum carbide or tantalum carbide and carbon, which is reinforced in three or more directions with high strength-high modulus carbon or graphite yarn, the amount of carbon in the matrix phase being a function of the amount of sucrose present in the aqueous solution of tantalum fluoride.
