    摘要: A multimode waveguide having a small thickness has light coupled to the side of the waveguide in order to provide a multimode operation of the waveguide for providing a continuous pattern of totally internally reflected light which is utilized to reconstruct holographic images from a holographic emulsion placed on a surface of the waveguide. This waveguide structure for reconstructuring a hologram has the capability of providing highly efficient hologram reconstruction while using ordinary light sources and is able to use beam diameters greater than the thickness of the waveguide.

    摘要: A sensor with magnetic blocks unevenly distributed in a housing includes, sequentially connected, a sensing element, a power assistance model processor (21), a digital-to-analog converter (27), and an operational amplifier (28). The sensing element includes permanent magnetic blocks (2) and a Hall element (3) arranged in a cavity fitted together by a rotating disk (1) and a fixing disk (40). Multiple permanent magnetic blocks (2) are fixedly arranged on the rotating disk (1) in a circular-annular distribution, and at most two of the permanent magnetic blocks (2) are different in intervals. On a certain side of the rotating disk (1), the magnetic polarities of adjacent permanent magnetic blocks (2) are opposite, namely, the magnetic polarities of all of the permanent magnetic blocks (2) on the certain side of the rotating disk (1) are distributed in a pattern of pole N, pole S, pole N.

    摘要: Tablet computers send relevant geographic and identification data to an application server (one of the tablets, or a local or remote server) which groups them to form a video wall. Once placed next to one another in substantially the same plane, the tablets snap photographs at more or less the same time and these images are transmitted to the application server. The server determines the relative positions of the tablets and then streams a portion of a video or digital image to each of the tablets in order that all tablets display the video or image in an integrated fashion. The tablets may operate independently or may rely upon the remote application server. Relative positions are determined by analyzing features and determining an up-down or left-right relationship between pairs of images, sorting images into vertical and horizontal rows, and placing the images into a grid.

    摘要: The invention provides a method and a device for on-line measuring the inner temperature of a cable joint, the device includes a built-in temperature measurer and an outside receiver. The built-in temperature measurer measures the temperature of the cable joint or a core wire surface by means of direct contact measuring method, and transmits the data to the outside receiver through an insulating layer by means of the radio frequency identification technique. At the same time, the outside receiver supplies power energy to the built-in temperature measurer by means of the radio frequency signal, so it resolves the problem of supplying power to the built-in temperature measurer. The device of the invention has the advantage of accurately measuring temperature, small volume, superior applicability and so on.
