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 |

20120275622 | Electronically compensated micro-speakers - Electronics for altering the audio frequency response of a micro-speaker without modifying the micro-speaker itself are used to provide a selected frequency response of the micro-speaker. The micro-speaker has a resonant peak region, from which the response declines for both higher and lower frequencies. In one embodiment the electronics includes a first circuit for modifying the frequency response curve up to the resonant peak region, and a second circuit for modifying the frequency response curve for audio frequencies higher than this region. Each filter yields an integer multiple of 6 dB per octave slope. In the described embodiment, for approximately correcting presbyacusis (age related hearing loss), a set of high pass filters, low pass filters, and/or high order filters are connected to the micro-speaker to progressively attenuate the frequency response curve as the frequency decreases from 10000 Hz to 100 Hz. | 11-01-2012 |

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 |
20120038113 | HYDRODYNAMIC BACKUP RING - A seal backup ring is provided with undulating surfaces which create circumferential convergence with a relatively rotatable surface. The backup ring is configured so that differential pressure acting across a rotary seal forces portions of the backup ring against the relatively rotatable surface, closing, or substantially closing, the extrusion gap that the rotary seal is exposed to. In response to relative rotation between the backup ring and the mating relatively rotatable surface, the circumferential convergence promotes hydrodynamic lubrication within the dynamic interface that exists between the backup ring and the relatively rotatable surface. The modulus of elasticity of the backup ring is greater than the modulus of elasticity of the rotary seal. | 02-16-2012 |

20140028131 | MOTOR FOR A ROTATABLE AND ILLUMINABLE POINTER - The present invention relates to a motor designed for being mounted on a circuit board, the circuit board having a pointer side and a rear side. The motor can be used for rotating an illuminated pointer. The motor comprises a light conveying pointer shaft for projecting through the circuit board from the rear side of the circuit board to the pointer side of the circuit board. The pointer shaft is arranged to convey light to the pointer. The motor further comprises a light guide for conveying light from a light source mounted on the circuit board to a rear end of the pointer shaft, the rear end of the pointer shaft being on the rear side of the circuit board. Thus, the motor can be advantageously mounted on the rear side of the circuit board. | 01-30-2014 |

20150051868 | SYSTEM FOR MONITORING ROTATING ELEMENTS - A system for monitoring at least one rotating element is provided. The system can include a first sensor substantially aligned with a first rotating element, the first sensor being configured to detect a first marker on the first rotating element and thereby provide a first signal; a second sensor substantially aligned with a second rotating element, the second sensor being configured to detect a second marker on the second rotating element and thereby provide a second signal; and a measurement system coupled with the first sensor and the second sensor, wherein the measurement system is configured to: evaluate a time delay between a detection time of the first signal and a detection time of the second signal. | 02-19-2015 |
