62363840, May 22, 2001

Filed:

Aug 26, 1998

Appl. No.:

9/150637

Inventors:

David E. Didier - Mariette GA
Joseph W. Goode - Lawrenceville GA
James E. Strickling - Duluth GA
William R. Dunn - Alpharetta GA

Assignee:

Universal Avionics Systems Corporation-Instrument division and L-3 - Norcross GA
Communications Corporation - New York NY

International Classification:

G09G 336
G02F 1133
G02F 1141

US Classification:

345 87

Abstract:

The invention describes a method for electronically adjusting the viewing angle of a liquid crystal display within a panel fixed in location by the structure within which it is located, such as an electronic flight indicator unit. The adjustment in viewing angle is achieved by changing the bias voltage to alter the pre-tilt angle of the liquid crystal layer.

International Classification:

G09G 104
H01J 2974

US Classification:

315370

Abstract:

An improved system for continuously detecting and correcting the display in a cathode ray tube for errors in size and linearity. The system employs a crystal oscillator as a reference frequency to determine absolute error which is represented as "size" on the display screen, and relative error which is represented as linearity. The error is determined from the index pulse feedback, which is an output of a phase lock loop voltage controlled oscillator which is compared to the reference frequency to provide an error voltage level. This output level is then digitized and processed in terms of general control, interpolation, extrapolation, filtering, etc. , testing, and stored in digital memory. The digital error data is converted back to analog levels for insertion into a horizontal auxiliary amplifier circuit for linearity correction. A main horizontal amplifier circuit receives size correction.

Appl. No.:

8/948000

Inventors:

Joseph W. Goode - Lawrenceville GA
James E. Strickling - Duluth GA

Assignee:

Advanced Displays Corporation - Norcross GA

International Classification:

G01C 2100

US Classification:

340974

Abstract:

A liquid crystal display flight indicator unit having the capability to display a horizontal situation indicator (HSI) or an attitude direction indicator (ADI) on the viewing area of the same unit. Signals from existing aircraft electronics are processed to determine whether the incoming signal is an HSI or ADI graphical image to be displayed on the viewing area. A unique component layout is described to enable HSI and ADI to be contained within a unit having a chassis size not larger than previously known HSI and ADI units.

Assignee:

Avionic Displays Corporation - Deluth GA

International Classification:

H05B 3700

US Classification:

315 97

Abstract:

A method is provided in which a relatively cold lamp filament may be turned on for a brief period of time, then turned off, then turned on again, then off again, and this process repeated for successively longer periods of on time, until eventually the filament power is left on continuously. This "pulse starting" may be controlled by a programmable microcontroller in association with a power supply to the lamp filament. The result is a longer lasting lamp filament.

International Classification:

G09G 336

US Classification:

345 87

Abstract:

The present invention is directed to a method and apparatus for adjusting the viewing angle of a liquid crystal display. In a preferred embodiment of the present invention, a plurality of digital-to-analog converters are arranged in pairs which have a fixed relationship. By determining appropriate values for the digital-to-analog converters, a desired viewing angle may be obtained for a liquid crystal display.

International Classification:

G02F 133

US Classification:

345102

Abstract:

Described is a backlighting module that may be used in an electronic liquid crystal display device. The backlighting includes one or more lamps within a cavity of the module. The lamps are capable of a wide range of luminance including low-level luminance achieved by a unique burst modulation scheme for driving the lamps.

International Classification:

H03M 148

US Classification:

341111

Abstract:

The present invention is directed to a method and apparatus which utilizes a software-based digital signal processing circuit to generate a signal which is representative of the status of a movable component. A preferred embodiment of the apparatus of the present invention includes a synchro which is connected to a movable component. An analog reference excitation may be applied to the synchro, and the synchro generates analog synchro signals which bear a relationship to the status of the movable component. The analog synchro signals are converted to digital synchro signals by a plurality of analog-to-digital converters. A digital reference signal and the digital synchro signals are provided to a software-based digital signal processing circuit which preferably corrects constant and time-varying errors in the digital synchro signals and generates a status signal which is representative of the status of the movable component. For instance, the status signal may represent the angular position of the movable component. A different embodiment of the status signal may represent the angular velocity of the movable component.
