US Patent:

20090257508, Oct 15, 2009

Filed:

Mar 9, 2009

Appl. No.:

12/400250

Inventors:

Gaurav Aggarwal - Andover MA, US
Marcus Kellerman - San Diego CA, US
David Erickson - San Clemente CA, US
Robert Tosi - Littleton MA, US
Wade Wan - Orange CA, US

International Classification:

H04N 7/12

US Classification:

37524025, 375E07027

Abstract:

A video processing system is operable to perform one or more display queue trick (DQT) operations utilizing decoded frames queued in memory. The decoded frames are generated from the start of random access points (RAPs) in frame segments in an encoded video stream. Location of RAPs may be determined during decoding of the encoded video stream. Exemplary encoding scheme comprise MPEG, AVC and/or VC1. The DQT modes include forward and/or reverse display modes. The used frames are selected based on determination of DQT mode parameters, queuing limitations and/or frame properties of selected and/or unselected frames in the frame segments. Frame properties comprise frame discardability and/or display inter-frame dependencies between selected and/or unselected frames. The video processing system is operable to jump to preceding and/or subsequent RAPs during DQT mode operations. The video processing system is also operable to skip one or more RAPs during such jumps.

US Patent:

56040105, Feb 18, 1997

Filed:

Jan 11, 1996

Appl. No.:

8/587160

Inventors:

Dale E. Hartz - Seattle WA
David G. Erickson - Seattle WA
William B. Hopkins - Seattle WA
Christopher L. Pederson - Seattle WA

International Classification:

B32B 312

US Classification:

428118

Abstract:

Resin flow into the cells of a honeycomb core in sandwich structures is eliminated by using an unsupported film adhesive, a barrier layer, and a scrim supported adhesive layer between the composite laminate and the core. Superior panels with lighter weights, improved mechanical properties, and more predictable structural performance result by keeping resin in the laminate rather than losing it to the core cells.

US Patent:

Filed:

Nov 6, 2018

Appl. No.:

16/182340

Inventors:

- Burlington MA, US
David Erickson - Topsfield MA, US
Glen McLaughlin - San Carlos CA, US

Assignee:

InfraReDx, Inc. - Burlington MA

International Classification:

A61B 8/08
A61B 8/00
A61B 8/12

Abstract:

Disclosed is a high resolution intravascular ultrasound imaging system including a catheter with a rotatable imaging assembly and an image processor. The image processor in turn features a pulser configured to energize the ultrasound transducer of the rotatable imaging assembly with a multi-frequency ultrasound waveform signal. The image processor further contains a receiver configured to decompose received ultrasound energy as reflected by the target vessel into a plurality of individual subband signals, individually process these signals and reconstitute these signals into a high resolution image of the blood vessel. The IVUS system of the invention may be useful in characterizing cap thickness of vulnerable plaques or other detailed studies of blood vessels.
