US Patent:

56593740, Aug 19, 1997

Filed:

Dec 8, 1994

Appl. No.:

8/352005

Inventors:

Richard Ovid Gale - Richardson TX
Brian C. McCormack - Denton TX

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G09G 334

US Classification:

348771

Abstract:

Methods are disclosed by which the effects of a defective electromechanical pixel 20 having a beam 30 and a hinge 32,34 are mitigated. These methods may damage the hinge 32,34 or the beam 30 and comprise the step of applying a voltage sufficient to damage the hinge 32,34 or beam 30 of said electromechanical pixel 20 by mechanical overstress, thermal overstress, electrochemical reaction, or thermally induced chemical reaction. Other methods are also disclosed.

US Patent:

51353989, Aug 4, 1992

Filed:

Jul 31, 1990

Appl. No.:

7/560626

Inventors:

Glen A. Thornton - Garland TX
Robert C. Greenberg - Dallas TX
Brian C. McCormack - Dallas TX
Veronica B. Howard - Grapevine TX
Gary G. Bitter - Scottsdale AZ

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G09B 1902
G09B 506

US Classification:

434201

Abstract:

An electronic teaching device (10) provides several mathematical activities including Place Value, Trade, Target, Solve It, Word Problems, Estimate, Select and Calculator. The Place Value activity enhances the understanding of numbers by pictorially displaying the place values. The Trade activity enhances the understanding of addition and subtraction by allowing the user to trade between the ones' place value and the tens' place value to properly perform a mathematical operation. The Target activity emphasizes logical reasoning and problem solving. The Solve It activity uses the place-value system to develop logical reasoning. The Word Problems activity tests the user's knowledge of basic mathematical terms and facts. The Estimate activity develops the ability to estimate answers to problems. The Select activity allows the user to recognize basic math operations.
