    摘要: Method of motion-compensated video processing such as standards conversion, uses motion vectors assigned on a pixel-by-pixel basis. The pixels of an input video signal are written to locations in a video store determined by the motion vector assigned to that pixel. Multiple vectors can address a single written pixel to enable mixing of backward and forward vectors. A confidence value governs the accumulation of pixels and the later interpolation between motion compensated fields.

    摘要: A police baton sidearm having a baton main body and a crosshandle which isttached in a perpendicular manner to the baton main body at a position longitudinally displaced from the geometric center of the baton main body. The baton main body also houses a recessed trigger ahead of the crosshandle and means for launching a projectile. In order to achieve impact insensitivity a double action only firing mechanism is employed. The baton main body is constructed in two parts to accomodate breech loading and various connection schemes including interrupted and multilead threads on abutting portions of the baton main body. Guide rods or a hinge mechanism may be provided to accomodate one-handed loading. The police baton sidearm may also be equipped with gunsights and a laser pointing device for improving the accuracy of the user's aim.

    摘要: A selected fraction of solid particles having sizes, densities and/or weights in a selected range is separated from a mixture of articles by fluidizing the mixture in a bed using a fluidizing fluid to cause particles including the selected fraction to pass out of the top of the bed; conveying the particles in a conveying fluid to a suitable separator (e.g. a cyclone) wherein the selected particles fraction is separated from smaller, lighter particles; injecting the separated fraction from the separator into a utilization zone (e.g. a fluid bed reactor); entraining other particles in the conveying fluid to another separator (e.g. a cyclone) to produce solids-free conveying fluid which is recirculated for re-use. The original particles mixture may be obtained by separation (e.g. in a cylone) from fluid leaving the utilization zone.

    摘要: A launcher system and method for an unmanned aerial vehicle (UAV), wherein the launcher system comprises a barrel comprising a prepackaged internal pusher cup configured behind the UAV housed within the barrel; an expansion chamber operatively connected around the barrel, wherein the barrel extends out of a first end of the expansion chamber; a muzzle adapter operatively connected to a second end of the expansion chamber, wherein the first end of the expansion chamber is positioned opposite to the second end of the expansion chamber; a rifle slip-fitted to the muzzle adapter; and a stand operatively connected to the expansion chamber, wherein a triggering of the rifle causes the internal pusher cup to push the UAV out of the barrel at a predetermined launch velocity in order to attain a predetermined self-propelled flight trajectory.

    摘要: A rate converter for digitally converting the sample rate of a signal, has a first digital filter for deriving an intermediate signal at increased sample rate and a second digital filter for deriving an output signal at a decreased sample rate relative to that of the intermediate signal. The first filter is of relatively high order serving to double the frequency. Because the frequency change is a power of two, the aperture characteristic is straightforward and implementation is simple even at high order. The second filter is of relatively low order so that implementation is simple even with a time-varying aperture characteristic. The low order of the second filter does not however degrade the overall frequency characteristic.

    摘要: Video signal processing apparatus, particularly for converting from one broadcast television standard to another, utilizes a plurality of field stores which are read cyclically. Information is written simultaneously into a number of field stores and accumulated over a number of input fields. Line interpolation is conducted before information is written to the field stores.
