    • This invention relates to a method, device, computer program and computer program product for determining a mapping for a sequence of information-carrying values, including determining K representations of a sequence of information-carrying values in K successive stages, respectively, wherein in a first stage, a first representation of said K representations is determined to be equal to said sequence of information-carrying values, wherein in subsequent stages, each representation is determined by performing a mapping operation on the representation determined in the preceding stage, and wherein said mapping operation is the same for each stage; calculating, in each stage, a parameter from a transformation of the representation determined in said stage; and determining for which stage of said K stages an extreme value of said parameter is calculated. The invention further relates to a method, device, computer program and computer program product for inverse-mapping a mapped sequence of information-carrying values, and a system for the transfer of information-carrying values.

    • A method and device for capturing speckles are described. A highly coherent light emitted from a light source is used to illuminate a surface and produces scattered lights. The scattered lights pass through a light restrictive element and the diffracted lights produced by this restrictive element interfere with one another to generate a speckle pattern. An image sensor is then used to pick up the speckle pattern to form a speckle image. Therefore, the effects of diffraction and interference and a light restrictive element to enlarge the speckle size and reduce the variation of the speckle pattern during the movement of the imaging device are utilized, so that the speckle pattern can be clearly identified in the image. As a result, the method and device for capturing speckles are fairly stable and sensitive.
    • 描述用于捕获斑点的方法和装置。 从光源发出的高度相干的光用于照亮表面并产生散射光。 散射的光通过光限制元件,并且由该限制元件产生的衍射光彼此干涉以产生散斑图案。 然后使用图像传感器拾取斑点图案以形成斑点图像。 因此,利用衍射和干涉的效果以及光限制元件来增大散斑尺寸并减小成像装置运动期间散斑图案的变化,从而可以在图像中清楚地识别散斑图案。 因此,捕捉斑点的方法和装置是相当稳定和敏感的。

    • A phased array antenna module for use in the gigahertz bandwidth. The module includes a metallic core with a pair of chip carrier assemblies secured to opposite sides of the core. The core has an internal waveguide with a signal splitter for directing electromagnetic wave energy evenly to the two chip carrier assemblies. A flexible, cylindrical connector assembly electrically couples the chip carrier assemblies to an aperture board. The aperture board includes a plurality of dipole antenna radiating elements. The module core is coupled directly to a cold plate. A direct thermal path is created between the chip carrier assemblies, the module core and the cold plate for highly efficient cooling of the electronic components on the chip carrier assemblies.
