| 20100110084 | PARALLEL PIPELINE GRAPHICS SYSTEM - The present invention relates to a parallel pipeline graphics system. The parallel pipeline graphics system includes a back-end configured to receive primitives and combinations of primitives (i.e., geometry) and process the geometry to produce values to place in a frame buffer for rendering on screen. Unlike prior single pipeline implementation, some embodiments use two or four parallel pipelines, though other configurations having 2̂n pipelines may be used. When geometry data is sent to the back-end, it is divided up and provided to one of the parallel pipelines. Each pipeline is a component of a raster back-end, where the display screen is divided into tiles and a defined portion of the screen is sent through a pipeline that owns that portion of the screen's tiles. In one embodiment, each pipeline comprises a scan converter, a hierarchical-Z unit, a z buffer logic, a rasterizer, a shader, and a color buffer logic. | 05-06-2010 |

| 20100314545 | Terahertz Frequency Domain Spectrometer with Frequency Shifting of Source Laser Beam - An apparatus for analyzing, identifying or imaging an target including first and second laser beams coupled to a pair of photoconductive switches to produce CW signals in one or more bands in a range of frequencies greater than 100 GHz focused on and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral heterodyne process to generate an electrical signal representative of some characteristics of the target. The lasers are tuned to different frequencies and a frequency shifter in the path of one laser beam allows the terahertz beam to be finely adjusted in one or more selected frequency bands. | 12-16-2010 |

| 20090283680 | Terahertz Frequency Domain Spectrometer with Controllable Phase Shift - An apparatus for analyzing, identifying or imaging an target including an integrated dual laser module coupled to a pair of photoconductive switches to produce cw signals in the range of frequencies from 100 GHz to over 2 THz focused on and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral homodyne process to generate an electrical signal representative of some characteristics of the target with resolution less than 250 MHz. The photoconductive switches are activated by laser beams from the dual laser module. The lasers in the module are tuned to different frequencies and a phase shifter in the path of one beam allows the beams to have an adjustable phase difference. | 11-19-2009 |
| 20100277726 | Terahertz Frequency Domain Spectrometer with Integrated Dual Laser Module - An apparatus for analyzing, identifying or imaging an target including an integrated dual laser module coupled to a pair of photoconductive switches to produce cw signals in the range of frequencies from 100 GHz to over 2 THz focused on and transmitted through or reflected from the target; and a detector for acquiring spectral information from signals received from the target and using a multi-spectral homodyne process to generate an electrical signal representative of some characteristics of the target with resolution less than 250 MHz. The photoconductive switches are activated by laser beams from the dual laser module. The lasers in the module are tuned to different frequencies and have two distinct low frequency identification tones respectively that are used in conjunction with a stable optical filter element to permit precise determination of the offset frequency of the lasers. | 11-04-2010 |
| 20110133090 | Method of Detecting Organic Materials Using Terahertz Spectroscopy - Disclosed herein are methods of detecting organic materials, and more particularly, methods of detecting organic materials using terahertz spectroscopy. The method of detecting organic material using terahertz spectroscopy includes suspending organic material in a medium to form a sample; irradiating the sample with an illumination beam of electromagnetic radiation, the illumination beam having a plurality of frequencies in the range of about 100 GHz to about 2 THz; detecting radiation transmitted through and/or reflected from the sample; and, analyzing the detected radiation to identify the organic material, wherein the medium is selected from the group consisting of agar, guar gum, gellan gum, carrageenan, xantham gum, fibrous sodium pectate, and other agar substitutes. | 06-09-2011 |

| 20090002851 | Sub-Micron Adjustable Mount for Supporting a Component and Method - An optical assembly includes a light path and at least one optic to be positioned in the path. A support arrangement supports the optic having a foot arrangement including at least one foot that receives a direct manipulation with the foot slidingly engaged against a support surface to move the optic relative to the light path. Movement of the foot may move the optic along a predetermined path. The foot defines a footprint for engaging the support surface and receives the direct manipulation in a way which changes the footprint on the support surface to move the optic responsive to changes in the footprint. A movement arrangement may selectively bias the foot against the support surface during a movement mode, intended to permit movement of the foot against the support surface, and in a locked mode, intended to lock the foot against the support surface. | 01-01-2009 |
