  • Patent number: 6525729
    Abstract: A method of determining a z-buffer for a voxel data set, comprising first raycasting at least a first ray to determine a value for a first z-buffer element; and second raycasting at least a second ray to determine a value for a second z-buffer element, where said z-buffer element values are determined at different accuracies, which different accuracies are responsive to characteristics of the data set at a neighborhood of said rays. Preferably, said different accuracies are achieved by modifying the accuracy of determination of an intersection between a cast ray and a solid voxel of said data set. Alternatively or additionally, said different accuracies are achieved by modifying the density of raycasting into the z-buffer.

  • Patent number: 6456822
    Abstract: A method and device for achieving reliable prevention of cellular telephone calls, within a given area. In the preferred embodiment, the device and method operate to block the control frequencies of the cellular system within a given area. The device broadcasts a blocking signal with a low power output, which interferes with the reception ability and decoding of signals and commands broadcast at the control frequency. Thus, the handshake routine of the telephone/cellular subscriber with the local cellular system is prevented. Operation of the device is achieved in several ways, manually, automatically, and/or by remote control. Its operation prevents cellular communication ability by subscribers within the area or within the effective blocking range, which is derived from the effective radiated power (ERP) of the blocking signal, its type and the type of communications/or blocked system.
