    • The present invention is a chair or similar body-supporting apparatus for sitting on, reclining on or lying upon. The chair or similar apparatus is capable of transmitting sound and vibrations generated by a sound source and/or a vibration source to a user's body. The sound and vibrations are transmitted through speakers, transducers, or a combination thereof which are connected to the chair or similar apparatus. The transmitted sound and vibrations may include translated frequencies that are generated by a translation of higher frequencies that can mainly be heard to lower frequencies that can mainly be felt. The present invention is also a method of providing vibrational energy to a user, including regulating sound and vibrations transmitted through speakers, transducers, or a combination thereof which are connected to a chair or similar body-supporting apparatus.

    • Reactive armour comprises an explosive reactive armour module comprising a first triggering screen and an explosive layer; and at least one explosive module placed in proximity to the reactive armour module and connected to said first triggering screen for detonation. The reactive armour module may have shaped charges to produce a shaped wavefront, and the triggering screen may be divided into at least two triggering parts, each part triggered by a different approach angle of an incoming projectile and each part configured to initiate an explosion in a different part of the reactive armour module or in a different explosive module if provided.

    • The SAR Point Cloud Generation System processes synthetic aperture radar (SAR) data acquired from multiple spatially separated SAR apertures in such a manner as to be able to calculate accurate three-dimensional positions of all of the scatterers within the imaged scene. No spatial averaging is applied thus preserving the high resolution of the original SAR data, and no phase unwrapping processes are required. The effects of height ambiguities are significantly reduced in the SAR Point Cloud Generation System. The SAR Point Cloud Generation System also self- filters against mixed-height pixels that can lead to incorrect height estimates. The system estimates scatterer height by a maximization of an Interferometric Response Function.
    • SAR点云生成系统处理从多个空间分离的SAR孔径获取的合成孔径雷达(SAR)数据,以便能够计算成像场景内所有散射体的准确三维位置。 不应用空间平均,从而保持原始SAR数据的高分辨率,并且不需要相位解包过程。 SAR点云生成系统中高度模糊度的影响显着降低。 SAR点云生成系统还可以对混合高度像素进行自动过滤,从而导致不正确的高度估计。 系统通过干涉测量响应函数的最大化来估计散射体的高度。

    • A bi-directional interface system between a wireless system and a cable system comprises means for operating a mixer as a bi-directional device to concurrently perform upconversion in one direction and downconversion in the other. Input signals are applied to the mixer at both its RF and IF ports and output signals are extracted from the same ports. A signal is also applied to the LO input of the mixer as required in the mixer. Preferably the system uses a high level mixer. In a wireless LAN system with coverage over a first area, a method for increasing the LAN coverage to a second area includes uses connecting signals from the first area into a cable system using a first bi-directional interface, and connecting back to wireless at a remote location.
