Rotationally Diverse Antennas

Invention SummaryState-of-the-art wireless communication antenna systems lose significant signal strength when users move their device through a wide range of typical orientations. Rotationally diverse antennas solve this problem by improving signal strengths by 8 dB on average or 30 dB at a 90% reliability level. These benefits lead to savings in transmission...

Stereo Acoustic Echo Cancellation

Invention SummaryStereophonic acoustic echo cancellers often suffer from slow convergence and large deviation of echo canceller tap weights from their true values (misalignment). Both of these happen because of significant correlations among signals in the acoustic paths. Non-linearity effects are usually introduced to reduce such correlations and thereby...

Optical Pyrometer Pressure Testing Station

Invention Summary: Currently optical/laser profilometers do not have the ability to apply pressure or vacuum to individual devices or wafers. While laser interferometers are used to measure the overall deflection of diaphragms in pressure sensors, they only provide point measurements on the diaphragm and are susceptible to large error. This technology...
