    • A system and method for a single spatial stream based multiple-input multiple-output (MIMO) communication system in wireless MIMO channels with a non-zero mean or a fixed component is provided which utilizes deterministic beamforming in the transmitter and deterministic combining at the receiver. For transmission and reception of a data over MIMO channels, the method and system avoids the requirement of knowledge of the instantaneous channel values at the transmitter and the receiver. By assuming perfect knowledge of the mean value of the channel matrix at the transmitter, a beamforming vector is obtained for the transmitter. The receiver utilizes deterministic receive weights which are chosen using the channel statistics.
    • 提供了一种用于具有非零均值或固定分量的无线MIMO信道中的基于单个空间流的多输入多输出(MIMO)通信系统的系统和方法,其利用发射机中的确定性波束形成和在接收机处的确定性组合 。 为了在MIMO信道上发送和接收数据,该方法和系统避免了在发射机和接收机处了解瞬时信道值的要求。 通过假设对发射机的信道矩阵的平均值的完全了解,为发射机获得波束形成向量。 接收机利用使用信道统计量选择的确定性接收权重。

    • A sonic paddle is a hand held device used for Martial arts striking practice. The sonic paddle is formed of layers of dense foam, rigid plastic, and plastic film resonating sheets. A cushioning layer is positioned on an outer surface of each of the resonating layers. The rigid center, supporting layers, resonating layers, and cushioning layers can be coupled to one another in sandwiched relationship. The part that the person strikes is the cushioning layers on either side of the paddle which are smaller in circumference than the resonating sheets leaving the resonating sheets protruding in order to resonate upon impact and thereby creating a loud sound when hit.

    • Electrical appliance that can be used in industry for cooling or freezing products with maximum speed by selecting the desired temperature or time from a control panel. The gas R410A, when introduced into the compressing motor is responsible for compressing the gas of the circuit passing through the coil. The condenser, the first filter dryer, the capillary tube, the evaporator, the second filter dryer being strategically placed for rearranging the particles and molecules, continuing through the coil until returning to the compressing motor. This set of components becoming a single closed circuit, without the need to be recharged. One or more fans are placed on walls or ceiling of the evaporator for transmitting a cold shock or thermal sensation making use of the cold existing within the evaporator. A second filter can be strategically placed for cooling with maximum speed.
