摘要： A method and apparatus provide an improved EM reverberation chamber which facilitates the dynamic three dimensional (3D) manipulation of EM field polarization within the chamber and produces a uniform field distribution inside the chamber. The chamber includes one or more walls with tunable lumped elements. A controller is provided to generate one or more control signals that are applied to the lumped elements and tunes their impedance in response to the one or more control signals. The result is to generate, within the chamber an electromagnetic field that appears to be random or pseudo-random in polarization, but which is sufficiently uniform in magnitude for EM testing.

摘要： A method for performing a signal integrity analysis on an integrated circuit (IC) that includes a plurality of scatterers by dividing the scatterers into subgroups using a nested Huygens' equivalence principle algorithm and solving a set of equations realized thereby with a reduced coupling matrix. The method includes decomposing the IC design into a plurality of small non-overlapping circuit sub-domains, wherein each of the sub-domains is formed as a small, enclosed region. Each sub-domain is analyzed independently of the other sub-domains using only electric fields to represent the interactions of each sub-domains with the other sub-domains as equivalent currents on equivalent surfaces of the plurality of sub-domains. Neighboring equivalent sub-domains are grouped together to form larger sub-domains using equivalent currents on equivalent surfaces to represent the interactions of the sub-domains. The steps of analyzing and grouping the sub-domains are repeated until the grouping approaches a box comprising the entire domain, and that the domain interactions between every sub-domain have been analyzed.

摘要： A multifunctional enclosure cushion comprises a floor mat, wherein the floor mat comprises an outer edge, a pillow bag is connected to the outer edge, and the pillow bag has a parabola-shaped cross section and comprises two peripheral end points; and an envelope, wherein the envelope is provided with an outer edge, an inner edge and a central axis, wherein the inner edge is connected with the outer edge of the floor mat, the pillow bag is formed with a concave shape at the position of the central axis, and two wire harnesses are respectively fixed to the two peripheral end points; the two wire harnesses extend oppositely along the outer edge of the envelope and meet at the central axis to form a pull ring; when the pull ring is pulled, the two wire harnesses drive the two peripheral end points of the pillow bag to gather in the direction of the central axis, and at this time, the pillow bag turns up along the outer edge of the floor mat to form an enclosure. The enclosure cushion which forms the enclosure state can prevent the babies in the enclosure cushion from climbing out of the floor mat to cause danger, and at the same time, the enclosure cushion also has a variety of functions such as backrest, pillow, baby cradle, floor mat, etc.
