Title: Method and system for measuring the shape of a reflective surface, and method for calibrating the system
Inventor: STEPHAN WIENAND
IPC: G01B11/24
Filed: 2007-04-02
Granted: 2011-09-01
Abstract: The method involves acquiring a position and an orientation of a camera (1) and a sample (15) e.g. laminar sample, where the sample reflects at a reflecting surface (14) and the camera is used for pixelwise observation of the sample. A surface angle and a surface height are determined for form measurement from a line of vision of the camera and the positions of the sample, where the positions of the sample correspond to an image of the reflected sample on the pixels (8) of the camera. Independent claims are also included for the following: (1) a system for measuring form of a reflecting surface of an object (2) a method for calibrating a system for measuring form of a reflecting surface.

Title: Optimized scheduling method using ordered grants from a central controller
Inventor: HOU VICTOR
IPC: H04B3/04
Filed: 2007-07-18
Granted: 2013-08-21
Abstract: A method, system, and computer program product for ordering grants of upstream bandwidth in a two-way grant-based communication system, such as a DOCSIS-based communication system. Typically, a central controller, such as a CMTS, sends a grant message to a set of end user devices, e.g., cable modems, wherein the message defines when each end user device can transmit upstream. The invention first determines, for each end user device, the time needed for processing the grant message. The central controller then constructs the grant message, such that grants for the end user devices associated with the shortest grant message processing times occur early in the grant message and represent the earliest grants. Grants for end user devices associated with the longest grant message processing times occur later in the grant message and represent later grants. With this ordering of grants within the grant message, the CMTS can assume a smaller processing time for processing the grant message by CMs, such that the grant message does not have to be sent so far in advance. Performance of the system is increased due to decreased roundtrip delay.

Abstract: A display device and a method of applying the same are introduced herein. A shielding layer is utilized to interpose between a transparent conductive layer of a touch element and a common electrode layer of a liquid crystal display (LCD) panel. With controlling variances of a first and a second control signals, a coupling current between the transparent conductive layer and common electrode layer can approach none, whereby influences of capacitive coupling effect between the common electrode layer or shielding layer and the transparent conductive layer of the touch element can be reduced. Thus, high touch accuracy of the touch element can be achieved and the noise can be eliminated simultaneously.

Abstract: Processing and apparatus are provided for upgrading the octane of a mixed hydrocarbon gasoline feedstock by an integrated adsorption-isomerization process which catalytically isomerizes normal paraffinic hydrocarbons and concentrates non-normals in a product stream, in both the reactor-lead and absorber-lead configuration. The process includes passing an absorber feed stream comprising hydrogen as well as hydrocarbons to an absorbent bed to absorb normal hydrocarbons. The hydrogen is preferably obtained from a hot hydrogen-containing process stream which is not cooled or separated into component parts prior to forming the absorber feed. In some embodiments, the hot-hydrogen containing stream comes from reactor effluent and in others from desorption effluent. According to the invention, the only hydrogen which will require cooling and separation from a hydrocarbon component is that which is recycled for desorption. The invention provides improved energy efficiency and can reduce equipment size and complexity.
