| 20090142020 | OPTICAL MICROSTRUCTURES FOR LIGHT EXTRACTION AND CONTROL - The application of optical micro structures improve the quality of light available to the viewer of an optical display system, or any display which works on the concept of moving one surface into direct contact or close proximity of a light guide to extract light through frustrated total internal reflection. Certain ones of the microstructures can act to assist in overcoming suction between the surface and the light guide. | 06-04-2009 |

| 20100266153 | ELECTRONICALLY COMPENSATED MICRO-SPEAKERS AND APPLICATIONS - Electronics for altering the audio frequency response of a micro-speaker without modifying the micro-speaker itself; the micro-speaker having a resonant peak region. In one embodiment the electronics includes a first circuit for flattening the frequency response curve up to the resonant peak region, and a second circuit for flattening the frequency response curve for audio frequencies higher than this region. Preferably, the extent of the flattened response over such range of frequencies is in the range of plus or minus 3 dB. The first circuit includes one of the group consisting of a high pass filter and a low pass filter, while the second circuit includes the other of this group. Each filter yields an integer multiple of 6 dB per octave slope. In another embodiment, for correcting hearing loss, a high pass filter is connected to the micro-speaker to progressively attenuate the frequency response curve as the frequency decreases. | 10-21-2010 |

| 20110140365 | ROTARY SEAL WITH SUPPORTED INLET - A hydrodynamically lubricated sealing element for applications where the pressure of a contained fluid can be significantly greater than the pressure of the seal lubricant. The sealing element retains the pressure of the contained fluid and provides hydrodynamic lubricant pumping activity at the dynamic sealing interface to enhance service life. The invention is particularly suitable for oilfield drilling swivel washpipe assemblies, downhole drilling tools, and rotary mining equipment, and for applications such as artificial lift pump stuffing box assemblies and centrifugal pumps where a rotating shaft penetrates a pressurized reservoir that is filled with abrasive-laden liquids, mixtures, or slurries. | 06-16-2011 |
