Title: Vertical cavity surface emitting lasers with consistent slope efficiencies
Inventor: SCOTT JEFFREY W
IPC: H01S5/00
Filed: 1999-11-12
Abstract: A vertical cavity surface emitting laser, VCSEL, (2) with variable tuning layer (10) for adjusting the slope of the laser (2) and method for manufacturing the same are disclosed.      In practice, a VCSEL wafer is grown by any conventional technique, and fabricated into discrete lasers (2) while maintained in wafer form. The initial lasers (2) are then tested to determine characteristics, such as the slope efficiency distribution to within a target specification by altering the phase of the top facet reflectivity of the initial lasers (2).      The resulting change in transmission directly changes the laser slope in a predictable fashion.      The tuning step may be repeated, if necessary, to further refine. the slope to the desired value. The method produces VCSELs (2) with similar or consistent slopes from a plurality of wafers. Also disclosed are an optical subassembly (110) and optical transceiver (130) incorporating the improved VCSELs.

Inventor: HUFFER SCOTT W
IPC: B41M1/10
Filed: 2001-11-27
Abstract: A method of printing and the resulting printed product is disclosed which provides a three dimensional raised look and feel without requiring expensive embossing rollers. A surface tension lowering additive is added to ink or clear resin or varnish, and the ink is printed onto a substrate in a pattern of substantially parallel lines, leaving spaces of substrate exposed between the lines of ink or clear resin or varnish. The clear resin or varnish may also be printed on a clear film and ink is then printed on the resin or varnish. The film can then be laminated to a metallized film, foil or other reflective surface. A  resin coating is applied over the printed pattern. The resin collects in the areas of exposed substrate due to the differential surface tension. The result is a pattern of raised resin profile ridges oriented along the pattern of ink lines.

Title: Acoustic source range detection system
Inventor: ZAKARAUSKAS PIERRE
IPC: G10L21/02
Filed: 2000-10-30
Abstract: The invention includes a method, apparatus, and computer program to determine whether a sound source is situated near or far from a pair of microphones situated within a reverberant space. A signal detector is applied to the data;  only the data that passes the signal detector is processed any further. The signal at the two microphones is compared to obtain the angular distribution of acoustic power. The concentration of acoustic power in the direct path versus reverberant paths is determined and used to compute a direct-to-reverberant ratio. If this ratio is greater than a selected threshold, the sound source is determined to be near the microphones. Otherwise, the sound source is determined to be far from the microphones.
