  • METHODS AND APPARATUS FOR SYNCHRONIZING MULTIPLE PROCESSORS OF A VIRTUAL MACHINE
    Publication number: 20140229940
    Abstract: Methods and apparatus for synchronizing multiple virtual processors of a virtual machine are disclosed. A hypervisor schedules a first virtual processor in a virtual machine to execute using a first physical processor. Subsequently, the hypervisor receives an indication from the first virtual processor that it is waiting on a second different virtual processor. If the second virtual processor is not already running on another physical processor, the hypervisor saves the priority associated with the first virtual processor, lowers the priority associated with the first virtual processor, and schedules the second virtual processor to execute using the first physical processor or another physical processor.

  • Apparatus, methods and system for improved lightweight armor protection
    Patent number: 8770085
    Abstract: An apparatus, method and system to enhance the performance of composite armor by utilizing the energy of the threat projectile is disclosed. The frontal member includes, for example, a plurality of concentric proves on the face opposite of the surface that is impacted by a projectile. The grooves in the frontal member preferably may mate with a complimentary plurality of concentric grooves in a backing plate. During impact by a projectile, the force from the projectile presses the grooves of the frontal member into engagement with the grooves of the backing plate. The grooves are uniquely designed to cause the backing plate to impart a compressive load into the backside of the frontal member preventing it from prematurely fracturing in tension at the onset of the projectile penetration.

  • Reducing transmitter-to-receiver non-linear distortion at a transmitter prior to estimating and cancelling known non-linear distortion at a receiver
    Patent number: 8744009
    Abstract: A communication system is provided that includes a transmitter device and a receiver device. The transmitter device transmits input data as a transmitted signal having the known non-linear distortion (NLD) characteristic. The receiver receives a received signal that represents a channel affected version of the transmitted signal and that has the known NLD characteristic. The received signal includes power amplifier distortion (PAD) induced by the transmitter device's power amplifier. The receiver is designed to iteratively estimate, based on the known NLD characteristic, remaining PAD caused by the power amplifier, and to iteratively cancel estimated PAD to reduce PAD in the received signal.

  • Methods for filling holes in printed wiring boards
    Patent number: 8726498
    Abstract: The invention comprises methods for filling holes in printed wiring boards and printed wiring boards produced by these methods. The methods involve plating metal conductors inside the holes of the printed wiring boards while protecting the conducting surfaces of the printed wiring boards from being plated using photoresist film. The side surfaces of a printed wiring board are covered with photoresist. The photoresist is exposed to developing light, except the photoresist covering the holes on one side of the board is masked to prevent exposure of the holes to the developing light. The undeveloped photoresist covering the holes is removed. The board is subjected to a plating process, which deposits conductive materials in the holes, but the photoresist on the conducting surfaces of the board prevents conductive materials to be plated on the surfaces of the board.

    Abstract: A phase shift device includes an input quadrature junction for receiving an input EM signal and extracting a first electromagnetic (EM) signal, a second EM signal, a third EM signal, and a fourth EM signal from the input EM signal. Four waveguide arms are operatively connected to the input quadrature junction for respectively conveying the first, second, third, and fourth EM signals therethrough. At least two of the waveguide arms shift the phase of EM signal conveyed therethrough such that two of the first, second, third, and fourth EM signals are phase shifted with respect to the other two of the first, second, third, and fourth EM signals. An output quadrature junction is operatively connected to the waveguide arms for combining the first, second, third, and fourth EM signals. Thus, polarization adjustment may be achieved through rotation of the phase shift device.
