20110175532 | SYSTEM AND METHOD FOR SUPPLYING CONSTANT POWER TO LUMINUOUS LOADS - An apparatus is disclosed that is capable of delivering substantially constant power to a luminous load in response to variation in the input voltage and variation in the environment temperature. The apparatus may be further adapted to vary the power supplied to the luminous load in response to changes in the input voltage produced by a dimmer circuit. In other words, during non-dimming applications, the apparatus is able to maintain substantially constant power supplied to the load even though the input voltage and environment temperatures are varying during typical daily operations. Additionally, if the input voltage is changed due to a user controlling a dimmer device to control the brightness of the luminous load, the apparatus is able to control the power delivered to the load in response to the dimmer device. | 07-21-2011 |

The alternating current is based on a first signal derived from the input voltage, a second signal derived from the current, and a third signal varying substantially in-phase with the input voltage. The first and second signals are used to regulate the power delivered to the load, and the third signal is used to improve the power factor. A load interface circuit is provided to generate an output voltage for the luminous load based on the alternating voltage from the transformer.

Additionally, since the ballast and the light emitting source are respectively disposed on and attached to the interface member between the metallic sheet ballast housing and the metallic sheet reflector, heat generated by these devices may be easily dispersed via the ballast housing and the reflector. | 10-23-2014 |

For example, the first aerial image may be obtained using an aerial image measurement system, and the inspection image may be a critical-dimension scanning-electron-microscope image of the photo-mask. This image, which has a higher resolution than the first aerial image, may indicate spatial-variations of a magnitude of the transmittance of the photo-mask.

20090195541 | RENDERING DYNAMIC OBJECTS USING GEOMETRY LEVEL-OF-DETAIL IN A GRAPHICS PROCESSING UNIT - The present embodiments provide a system for graphically rendering an object. This system operates first by pre-processing a geometry mesh for the object offline, wherein the geometry mesh is partitioned into a set of patches, and wherein each patch is bounded by a bounding box. The system then builds a multi-resolution representation for each of the set of patches. Next, during real time rendering, the system deforms the bounding boxes associated with the set of patches through superposition of object motions in each frame weighted by a set of predetermined mesh-skinning parameters. For each deformed bounding box, the system computes a geometry level-of-detail (LOD) value based on a projected area of the deformed bounding box in screen space. The system next deforms the object through a set of mesh skinning operations. The system then renders the deformed object based on the computed geometry LOD values for the set of patches and the multi-resolution representation for the geometry mesh. | 08-06-2009 |
