| 20090309441 | SENSOR FASTENING METHOD AND SENSOR FASTENING FRAME FOR USE THEREWITH - A sensor fastening method and a sensor fastening frame for use therewith are provided. The sensor fastening frame is coupled to a motor stator of a brushless motor having distributed coils and extends over the distributed coils to allow the sensor fastening frame to rotate about the axle of a motor rotor, without interference with the distributed coils. At least a sensor is fastened in position to the sensor fastening frame proximate to one end of the axle of the motor stator for positioning the sensor to detect magnetic field variations of the motor rotor. | 12-17-2009 |
| 20120025655 | MOTOR ROTOR AND MOTOR HAVING THE MOTOR ROTOR - A motor rotor includes an annular body and a magnetic body installed on an inner lateral surface of the annular body. The magnetic body has a first curved surface and a second curved surface opposing the first curved surface. The magnetic body props against the inner lateral surface of the annular body via the first curved surface. The first curved surface has a first curvature less than a second curvature of the second curved surface. Because the magnetic body of the motor rotor has an uneven thickness, and an air gap interval formed between the motor rotor and the stator also has an uneven width, forces applied to a region where the magnetic forces change directions are smooth. Therefore, the vibration of the whole motor is reduced, and the noises are suppressed effectively. | 02-02-2012 |

| 20090309448 | END COVER AND MOTOR ROTOR HAVING THE END COVER - An end cover adapted to engage with an end surface of a spindle of a motor rotor is proposed for securely coupling to the spindle with a plurality of permanent magnets disposed around the peripheral wall of the spindle. The end cover has a first surface facing an end surface of the spindle and an second surface opposing to the first surface, which is formed with a plurality of inserting slots indentedly disposed around the rim thereof and corresponding to the permanent magnets for coupling the ends of the permanent magnets, thereby securely fastening each of the permanent magnets to the spindle of the motor rotor. Further, the present invention further provides a motor rotor having the end covers described above. | 12-17-2009 |

| 20130135784 | Electrostatic Chuck Robotic System - A workpiece transfer system has a plurality of joints having a bearing and a primary and secondary transformer coil, wherein power provided to the primary transformer coil and secondary transformer coil of each joint produces mutual inductance between the primary and secondary transformer coil of the respective joint. A first pair of arms are rotatably coupled to a blade by a first pair of the joints, wherein the primary transformer coil of each of the first pair of joints is operably coupled to the first pair of arms, and the secondary transformer coil of each of the first pair of joints is operably coupled to the blade and an electrode beneath a dielectric workpiece retaining surface of the blade. The electrode is contactlessly energized through the transformer coils of the joint and the blade can chuck and de-chuck a workpiece by reversing current directions and by voltage adjustment. | 05-30-2013 |
| 20130136873 | APPARATUS AND METHOD WITH DEPOSITION CHAMBER HAVING MULTIPLE TARGETS AND MAGNETS - A thin film deposition system and method provide for multiple target assemblies that may be separately powered. Each target assembly includes a target and associated magnet or set of magnets. The disclosure provides a tunable film profile produced by multiple power sources that separately power the target arrangements. The relative amounts of power supplied to the target arrangements may be customized to provide a desired film and may be varied in time to produce a film with varied characteristics. | 05-30-2013 |

| 20110305019 | LED STREET LIGHT - An LED street light includes a central housing portion having two spaced-apart sidewalls, and two lateral housing portions disposed respectively on two opposite longitudinal sides of the central housing portion. Each lateral housing portion includes a first plate fixed to a respective sidewall and having a first plate opening, a second plate connected to the first plate, a curved plate connected to the second plate, and a reflection layer disposed on the curved plate and facing one of the sidewalls. The first plate and the curved plate of each lateral housing portion have bottom ends defining a bottom opening. A plurality of light-emitting modules are disposed on each sidewall. Each light-emitting module includes at least one LED element, and extends into one of the lateral housing portions through the first plate opening. The reflection layer reflects the light emitted by the LED element toward the bottom opening. | 12-15-2011 |
| 20110317432 | LIGHT-EMITTING DIODE LENS - A light-emitting diode (LED) lens for covering a LED light source includes a lens body made of a transparent material. The lens body has a light-exit surface and a light-entrance portion. The light-exit surface is configured along the longitudinal direction into a pair of convex surface areas and a concave surface area interconnecting the convex surface areas. The concave surface area has minimum dimensions smaller than maximum dimensions of each of the convex surface areas along first and second transverse directions. The light-entrance portion is adapted for receiving the LED light source, and has a light-incident surface. The light-incident surface has a pair of end portions opposite to each other along the longitudinal direction and extending inclinedly away from the light-exit surface and away from each other. | 12-29-2011 |
| 20120044687 | LED LAMP - An LED lamp includes a lamp seat and a light assembly. The lamp seat includes a heat-dispersing unit having a plurality of tubular members extending in a horizontal direction and disposed in a side-by-side manner. Each of the tubular members defines a tubular space. The light assembly includes a light module having an LED element. The light module is mounted directly or indirectly on the tubular members of the heat-dispersing unit. | 02-23-2012 |
