Abstract: An input device encodes motion using a laser self-mixing velocimeter. The laser beam is directed at a disk or other moving member. As light from that beam is reflected back into the emitting cavity of the laser, the beam power output fluctuates because of the self-mixing effect and generates a beat signal. The beat signal frequency is used to determine the speed of the member's motion. The direction of motion is also determined based on the beat signal. A difference frequency analog phase locked loop filters the beat signal. A zero-point control disables motion detection when the average beat signal amplitude falls below a threshold. A triangle modulator generates a triangle wave for the laser bias current, with the triangle wave frequency being a submultiple of the beat signal frequency.

Abstract: A data input device for use with a tracking surface having light-scattering properties with respect to the device. The device comprising a single laser having a modulated light beam. A beam splitter splits the modulated light beam into two light beams projected along separate paths toward the tracking surface. A portion of the light striking the tracking surface reflects back into a cavity of the single laser for self-mixing with the projected light, thereby altering first and second characteristics of the projected modulated light beam according to first and second directions associated with the tracking surface. A detector associated with the laser detects the altered first and second characteristics of the modulated light beam projected by the laser, and a controller responsive to the detector determines the relative movement of the tracking surface and data input device relative to one another as a function of the altered first and second characteristics detected by the detector.

Abstract: A net structure for use of both sports and leisure is mainly made up of a net body having a plurality of net yarns integrally woven into a large meshwork of coarse and three-dimensional cords wherein within each net hole of the large meshwork is interwoven a small net layer to form a net-within-net fabric structure. The large meshwork is increased in frictional resistance for barring objects caught at the net body therein; the small net layer can gather the outstretched large meshwork thereof, preventing the large meshwork from getting loose easily and permitting the net body thereof to be flexibly expanded within a certain range. The small net layer also forms a protective layer to stop objects like balls from breaking through thereof. Moreover, the net body can be integrally woven by net yarns of two or more than two different colors with the large meshwork in contrast or matching with the small net layer in different colors to verify and increase the beauty of the net body in display.
