Title: System and method for reducing interference in an optical data stream using multiple, selectable equalizers
Inventor: LENOSKY THOMAS JAMES
IPC: H04B10/18
Filed: 2003-11-05
Abstract: A method of reducing interference in a data stream includes filtering the data stream using a first equalizer to output a first filtered data stream. Also, the data stream is filtered using a second equalizer to create a second filtered data stream. Then, one or more error rates based on the first filtered data stream and the second filtered data stream are determined. Based at least in part on those error rates, a filtered data stream is selected from among the first filtered data stream and the second filtered data stream. A  threshold value is determined, and then compared against the selected filtered data stream to generate a data bit.

Filed: 2003-11-04
Abstract: A polymer composite structure having resin matrix interlayers reinforced wit h shape memory alloy (SMA) particles. In one preferred form Nitinol.RTM. alloy particles are used for the SMA particles. The Nitinol.RTM. alloy particles m ay comprise cylindrical, oval or spherical shaped particles and are intermixed in the resin of the resin matrix interlayer(s) of the composite structure. The SMA particles provide superelastic, reversible strain properties that significantly improve the damage resistance, damage tolerance (e.g. compression-after-impact (CAI) strength) and elevated temperature performanc e of the composite structure without negatively affecting the hot-wet compression strength of the composite structure. The polymer composite structure is ideally situated for aerospace and aircraft applications where lightweight and structurally strong materials are essential.

IPC: A45B25/22
Filed: 2005-12-08
Abstract: This inventive change is to the family of umbrellas. Instead of being a folding circular cover of nylon etc. attached to ribs from a stick, that someone would carry, or a larger folding marketing type, this umbra or penumbra, (part shade) as I will refer to it, differs as follows:   The penumbra construction is based on a suspension system, built of plastic or aluminium, etc.  Because of its size, (twice the span of regular umbrellas) it is of rigid frame, and has to be assembled. The covering consists of six separate equilateral triangles of material, hemmed to receive elastic chords, to be stretched from the centre post to two of the outside posts of the perimeter. The chords hold the assemblage together, while also supporting the shade panels at alternating heights to alleviate wind updraft. The covering panels can be closed, and side panels added to produce a tent structure.

Title: Knee brace hinges having dual axes of rotation
Inventor: NATHANSON JEREMY
IPC: A61F5/01
Filed: 2005-01-05
Abstract: Disclosed is a knee brace that incorporates hinges that allow the brace to pivot simultaneously about a flexion-extension axis and a longitudinal rotation axis as the brace flexes and/or extends. The hinges include a medial hinge and a lateral hinge. The medial hinge defines a medial pivot axis and the lateral hinge defines a lateral pivot axis.
