Filed:

Oct 24, 2002

Appl. No.:

10/281384

Inventors:

John D. Hyde - Corvallis OR, US
David L. Kaplan - Seattle WA, US

Assignee:

Impinj, Inc. - Seattle WA

International Classification:

H03M001/66

US Classification:

341144, 341135, 341136

Abstract:

A method and apparatus for calibrating an electronic circuit which required scaled matching of some or all of its electronic components with nonvolatile programmably trimmable parameter sources (current, voltage, resistance, capacitance) is carried out in a top-down (highest order bit first, lowest order bit last) fashion without an analog division step. The method and apparatus are applicable, for example, to current-steering digital-to-analog converters (DACs), voltage-controlled oscillators (VCOs), voltage-steering DACs, and the like. In each of these applications the method and apparatus is used to match successive device outputs according to a desired scale factor, proceeding top-down from large output devices to smaller output devices, thereby successively shrinking the cross-device errors which accrue during the matching process.

Appl. No.:

12/991973

Inventors:

Detlev Boison - Portland OR, US
David L. Kaplan - Concord MA, US

Assignee:

TRUSTEES OF TUFTS COLLEGE - Medford MA

International Classification:

A61K 31/7076
A61P 25/08

US Classification:

514 46

Abstract:

This invention relates to sustained release formulations comprising silk fibroin biopolymer and adenosine, that provide for sustained, focal release of adenosine at therapeutic levels for the treatment of epilepsy and/or the prevention of epileptogenesis. An embodiment provides for a silk-based, adeno sine-releasing implant that alleviates seizures or prevents epileptogenesis. Another embodiment provides for a method of treating epilepsy or preventing epileptogenesis comprising focally administering adenosine in a sustained-release, silk-based adenosine delivery system.

Appl. No.:

8/775786

Inventors:

Susan J. Corwin - Portland OR
David J. Kaplan - Santa Clara CA
Thomas D. Fletcher - Portland OR

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G10L 500

US Classification:

704258

Abstract:

A method for compressing speech. An audio signal comprising speech is broken down into its phonetic components. These phonetic components are then converted into data elements that represent each of the phonetic components. The determination of data elements is accomplished using a predefined table that correlates phonetic sounds to data elements. The data elements representing the phonetic sounds are then stored.

US Classification:

84622

Abstract:

A method for compressing music into a digital format. An audio signal that corresponds to music is received and converted from an analog signal to a digital signal. The audio signal is analyzed, and a tone is identified. The musical note and instrument that correspond to the tone are determined, and data elements that represent the musical note and instrument are then stored.
