Abstract: The testing of a received data signal accessed from a device under test. Communication circuitry first generates an instruction that causes the device under to emit the data signal towards quality parameter contour generation circuitry. The contour generation circuitry is then configured to generate quality parameter (e.g., bit error ratio) contour of the data signal, which is then received at the contour generation circuitry. The generated contour map may then be evaluated to diagnose the performance of the device under test in emitting the data signal. For instance, each device under test may be evaluated after manufacture. The quality parameter contour generation circuitry may be embedded within an electronic device, such as a consumer electronic device. A diagnostic component within the electronic device is configured to use the quality parameter contour generated by the contour generation circuitry to self-test the device.

Abstract: An alternating unipolar carrier waveform is used to drive a pi-cell modulator. The pi-cell is driven by the carrier, but the carrier never changes polarity within the time period that the cell is energized. However, each time the cell is energized, i.e., once per field, the polarity alternates. Further, a burst of pulses each separated by a short rest period is used on initial application of power to more quickly drive the pi-cell to its activated state.

Abstract: A stereoscopic display system unambiguously tags the perspective view for left and right video fields by encoding at least one of the video fields with a unique code, then detecting the code in order to drive shuttered eyewear in synchrony therewith.

Abstract: Wireless active eyewear includes a frame having a front portion and a rear portion. A gasket and shutter assembly and a circuit board are held between the front and rear portions of the frame. The non-conductive gasket has electro-optical shutters integrally formed therewith and includes conductive plugs extending therefrom which electrically contact each of the electro-optical shutters and the circuit board. The frame includes temple arms hingedly attached thereto and an on/off switch which is actuated by opening and closing the temple arms.
