Filed:

Jan 7, 2005

Appl. No.:

11/031271

Inventors:

J. Alexander Fax - Los Angeles CA, US
Robert Griffith - Newhall CA, US

Assignee:

Litton Systems, Inc. - Woodland Hills CA

International Classification:

G01P 15/13
G01P 15/125

US Classification:

7351418, 7351432

Abstract:

A force balanced instrument system and method for mitigating errors is provided. The system and method mitigate errors in measurement readings caused by charge buildup in force balanced instruments that employ charge pulses to generate an electrostatic force to null an inertial proof mass disposed between opposing electrodes. The system and method mitigate charge buildup by applying positive charge pulses alternately to each opposing electrode for a given charge cycle time period followed by negative charge pulses alternately to each opposing electrode for a second given charge cycle time period. The negative charge pulses remove any residual charge on the electrodes caused by the positive charge pulses. As a result the net residual charge left on the electrodes is reduced on the average.

International Classification:

G06F 7/00

US Classification:

707708, 707761, 707771

Abstract:

The present invention provides a Distinct Author Identification System (“DAIS”) for disambiguating data to discern author entities and link or associate authorships with such author entities. The invention provides powerful disambiguation processes applied across one or more databases to yield a disambiguated authority database of authors. An entire database of publications may be processed by the DAIS to group/link authorships and to identify author entities. The author entities may then be matched or associated with actual authors to establish an authority database of authors. After initial evaluation, the DAIS may be used to reevaluate some or all of the database(s) and/or the authority database established by the DAIS may be used to add or update information. DAIS may use “hierarchical clustering” to link authorships and identify authors based on authorship similarity. DAIS evaluates the likelihood that authorships are from the same author.

13/332536

Inventors:

MICHAEL S. LARSEN - Woodlands Hills CA, US
Robert Griffith - Newhall CA, US
Michael D. Bulatowicz - Canoga Park CA, US
Philip R. Clark - Tarzana CA, US

International Classification:

G01R 33/12

US Classification:

324300

Abstract:

One embodiment of the invention includes an atomic sensing system. The system includes an atomic sensing device configured to generate an output signal along an output axis in response to a plurality of control parameters. The system also includes a signal generator configured to apply a reference signal to a cross-axis that is approximately orthogonal to the output axis. The system also includes a phase measurement system configured to demodulate the output signal relative to the reference signal to measure a relative phase alignment between the output axis and a physical axis of the atomic sensing device based on the reference signal.

Appl. No.:

5/900883

Robert C. Griffith - Encino CA

Assignee:

Dynamic Sciences International, Inc. - Woodland Hills CA

International Classification:

G06F 102

US Classification:

364718

Abstract:

A programmable sound synthesizer, controlled by a microprocessor, can be fabricated according to the present invention to provide arbitrary programmability with respect to the waveform of an audible tone, frequency, amplitude, envelope shape of the wave train, including attack, sustain and the decay intervals of the envelope, rest or space intervals between notes as well as arbitrary selection of the note within an ordered sequence. A plurality of binary numbers, which in sequence are indicative of the waveform of the tone to be generated, can be read from a memory at a rate which defines the frequency of the waveform. The memory is read by an address generator whose repetition rate is controlled by an integrater. The rate of integration is in turn controlled by a tone number which is programmed into an appropriate register coupled to the integrater. Envelope and amplitude information may also be programmed into corresponding registers.
