  • SYSTEMS AND METHODS FOR STORING A PLURALITY OF VIDEO STREAMS ON RE-WRITABLE RANDOM-ACCESS MEDIA AND TIME- AND CHANNEL-BASED RETRIEVAL THEREOF
    Publication number: 20110255838
    Abstract: A digital video recorder (DVR) and a method of operating the same. In one embodiment, the DVR includes: (1) a mass data storage unit that concurrently and continuously receives and digitally stores a plurality of channels and (2) a channel viewer, coupled to the mass data storage unit, that retrieves a portion of one of the plurality of channels from the mass data storage unit based on a received command and presents the portion on a video display device.
    Type: Application

  • Flexible magnetic pad
    Patent number: 6126588
    Abstract: A flexible magnetic pad for therapeutic use having single pole magnetic surfaces includes a mixture of a flexible synthetic material and magnetic particles having a high magnetic retentivity with a residual induction of at least 0.8 Tesla. Preferably, the synthetic material is silicone rubber and the magnetic particles are Neodymium-Iron-Boron. Sealing layers of flexible synthetic material surround the mixture to prevent disengagement of the particles. The pad is form-fitting to the contours of the body and has an elasticity enabling 200% elongation.

  • Method and apparatus for reducing the intensity of magnetic field emissions from video display units
    Patent number: 5561333
    Abstract: Method and apparatus for the reduction of the intensity of magnetic field emissions from video display units (VDU) in the vicinity of the user comprising a wire coil shaped to mimic the shape of conventional VDU deflection coils draped over a VDU to produce a cancelling magnetic field synchronous with the magnetic field produced by the unit's deflection coil. The cancellation coil is driven by a signature sensor disposed forward of the deflection coil that senses the characteristics of the magnetic field produced by the deflection coil. The gain of the cancellation coil is adjusted to maximize the cancellation coil's cancellation effect in the vicinity of the VDU user.
