US Patent:

54345880, Jul 18, 1995

Filed:

Dec 21, 1993

Appl. No.:

8/171139

Inventors:

Norman W. Parker - Wheaton IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G09G 336

US Classification:

345 98

Abstract:

In a liquid crystal display, a crosstalk correction signal which is the same for all video or pixel input signals is provided either directly from the input signals or from the column signal. The input signals are combined with the correction signal and modulated onto carrier signals, then, e. g. , may be coupled to the LCDs through a single-wire row or column connection. The correction signal can be derived from either the pixel input signals or the column signal.

Filed:

Jul 2, 1980

Appl. No.:

6/165474

Inventors:

Norman W. Parker - Wheaton IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04B 168

US Classification:

455 47

Abstract:

A single carrier is amplitude-modulated by a signal which is a transform (as the sine function) of the audio signal, and one set of sidebands is removed. In a receiver, the signal can be recovered by first deriving the Hilbert transform of the sine transform, and multiplying it by the signum of the derivative of the original audio signal to obtain the cosine transform. The sine and cosine transforms are then decoded to obtain the original audio signal.

Appl. No.:

6/325401

Inventors:

Norman W. Parker - Wheaton IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G01F 900
G01F 2328

US Classification:

73149

Abstract:

The volume of gases in a container or the volume of liquid in the container is determined by creating cyclic pressure waves in the gases and detecting the waves by a second transducer. The signals produced by the second transducer are a function of the volume of gas in the container, and the volume of any liquid can be obtained by simple calculation. The signals can also provide detection of an open container and, when coupled to signals relating to the velocity of a vehicle, can provide other data such as a miles-per-gallon reading.

Filed:

Apr 20, 1978

Appl. No.:

5/897988

Inventors:

Norman W. Parker - Wheaton IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04H 500

US Classification:

179 1GS

Abstract:

A system for the transmission and reception of two program signals L and R on a single channel by means of a compatible SSB AM stereophonic signal having the form (1+L+R)cos(. omega. sub. c t+. phi. ) where. phi. is arc sin{[(L-R)/. pi. /2] [1+(L +R)/2] / (1+L + R)}. The system is also applicable to transmission of one program signal on one set of sidebands.

Filed:

Nov 17, 1977

Appl. No.:

5/852272

Inventors:

Francis H. Hilbert - Addison IL
Norman W. Parker - Wheaton IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

H04H 500

US Classification:

179 1GS

Abstract:

An AM receiver for receiving a compatible stereo signal and requiring a dynamic correction factor prevents the introduction of a false phase reference signal by limiting and filtering the signal going into the oscillator of the PLL which provides the correction reference signal.

Appl. No.:

7/582441

Inventors:

Norman W. Parker - Wheaton IL
Robert C. Kane - Woodstock IL

Assignee:

Motorola Inc. - Schaumburg IL

International Classification:

H01J 2970
H01J 102

US Classification:

3151691

Abstract:

A cold-cathode field emission device controls electron emission by using a current source coupled to the emitter. The open circuit voltage of the current source is less than the voltage at which the FED would emit electrons. Application of an accelerating potential on the gate enables electron emission. Electron emission from the FED is governed by the current source.

International Classification:

H04H 500

US Classification:

179 1GS

Abstract:

An AM receiver for utilizing a broadcast signal of the form (1+L+R) cos (. omega. sub. c t+. phi. ) separates the L and R signals by utilizing phase detection and matrixing. Distortion is either eliminated with non-linear amplification or reduced with partial matrixing.
