Filed:

Mar 10, 2003

Appl. No.:

10/385242

Inventors:

Robert Freedman - Culver City CA, US
Steven Rogers - Los Angeles CA, US
Ruben Marquez - Canyon Country CA, US

Assignee:

NATIONAL FILM LABORATORIES, INC. dba CREST NATIONAL

International Classification:

G11B007/24

US Classification:

369/275400

Abstract:

The invention pertains to an optical disc having increased storage capacity that provides sufficient signals for readability in a majority of players. Pursuant to a first aspect of the invention, acceptable cross-talk levels and increased storage capacity are achieved by decreasing track pitch and pit width. Pit width is decreased based in part on the amount the track pitch has been decreased, and in part on cross-talk levels that are produced by the optical disc when scanned in a majority of players. Pursuant to a second aspect of the invention, acceptable data signals, acceptable tracking signals, and increased storage capacity are achieved by decreasing the pit lengths and by selecting a pit depth. The pit depth is selected based in part on the pit lengths, and based in part on the data signals and the tracking signals produced by the optical disc when scanned in a majority of players. Pursuant to a third aspect of the invention, a cross sectional shape of the pits is selected so that the cross sectional shape increases tracking signals produced by the optical disc when the disc is read in a majority of players.

Appl. No.:

7/763042

Inventors:

Donald J. Christian - Fremont CA
Steven W. Rogers - Maumelle AR

Assignee:

FMC Corporation - Chicago IL

International Classification:

G01M 1702

US Classification:

364463

Abstract:

The invention provides a wheel balancer that is able to determine if its measurements are accurate. The invention takes a set of measurements and determines if the measurements are sufficiently consistent. If they are sufficiently close the invention uses the measurements to calculate wheel imbalance. If the measurements are not sufficiently close the invention uses the measurements to calculate wheel imbalance. If the measurements are not sufficiently close the invention rejects at least one data point and collects more measurements until either the invention yields sufficiently close data points or the machine is stopped. A display is provided for diagnostic messages.

Appl. No.:

7/811504

Inventors:

Donald J. Christian - Fremont CA
James L. Dale - Conway AR
Steven W. Rogers - Conway AR

International Classification:

G01B 1126

US Classification:

356152

Abstract:

A wheel alignment system is disclosed which measures the angles between the planes of the wheels on the same side, at the front and diagonally opposite on a four wheel vehicle. The measurements are processed to provide wheel toe, relative wheel plane orientation, front wheel offset and front and rear wheel setback relative to the vehicle frame to assist in damage assessment.

Assignee:

FMC Corporation - Chicago IL

International Classification:

G01M 1900

US Classification:

738659

Abstract:

The disclosure herein relates to a wheel service machine, such as a wheel balancer, which provides audible output for guiding an operator to measured positions on a vehicle wheel assembly where corrective operations must be performed, such as the application of wheel assembly unbalance compensation weights.

International Classification:

G09F 3/18
G09F 3/02

Abstract:

A coding apparatus is mounted on a jumper cable. The coding apparatus includes a plurality of coding symbols. A selection mechanism is part of the coding apparatus and is operable to reveal a selected plurality of coding symbols of the plurality of coding symbols. The selected plurality of coding symbols, in combination, provide a code identifying a connection location for the jumper cable.
