    摘要: The invention provides for a material characterization system, method, and instrumentation for measuring the mechanical properties of nano-scale thin films. The thin film mechanical characterization system, method, and instrumentation of the present invention for ultra-thin films includes a motor and load cell. The instrumentation device includes a bath that can be filled or used with liquid so that a thin film can float via the surface tension and can be stretched until permanent deformation occurs, while recording the amount of force applied by the motor and other parameters. Further, the invention provides a process that transfers the nano-scale thin film to the tensile testing instrument and a process to obtain the physical mechanical properties of thin films that are at the nanoscale level.

    摘要: A system for simultaneous real-time three-dimensional geometry and color texture acquisition. The system includes a system processor for generating at least three phase shifted black and white fringe patterns with a phase shift of 2 π/3, a light projector adapted to project the fringe patterns onto an object, the projector being electrically connected with the system processor, and a color camera for capturing the fringe patterns to generate at least three raw fringe images. The fringe images are used to calculate a black and white texture image which is further converted to a color image by employing a demosaicing algorithm. The fringe images are also used to calculate a wrapped phase map that is further processed to generate a continuous unwrapped phase map by employing a phase unwrapping algorithm and the unwrapped phase map is converted to co-ordinates using calibrated system parameters for point-by-point three-dimensional shape measurement.

    摘要: A system controls the transfer of data. The system receives a request to transfer data and determines whether a counter value equals or exceeds a threshold. The counter value represents an amount of time since a previous data transfer. When the counter value equals or exceeds the threshold, the system transmits the data. In another implementation, the system tracks the amount of data read from a buffer. The system reduces the speed at which data is read when the amount of data read from the buffer exceeds a threshold.

    摘要: Apparatus and method for generating parameters used in coding data in a data transmission system. The method determines a number of possible coding parameters to satisfy a target coding gain and selects the best set of parameters that balance the code word length and the error rate. In this manner, a minimum coding gain may be used, which minimizes cross-talk on a transmission link.
