  • Patent number: 9834377
    Abstract: A lifting arm assembly is movable between a grabbing position and tipping position and includes a static frame provided with a roller arrangement. A dynamic frame is mounted for vertical movement relative to the static frame. A grabber structure is provided with a pair of grabber arms configured for movement between a closed position and an open position. A linkage arrangement has a first end pivotally connected to the dynamic frame, and a second end pivotally attached to the grabber structure. The first end includes a set of teeth arranged in meshing engagement with the roller arrangement on the static frame. Movement of the dynamic frame relative to the static frame causes pivoting of the linkage arrangement resulting in lifting movement of the grabber structure along a curvilinear path between the grabbing position and the tipping position.

  • Patent number: 6847905
    Abstract: A method and apparatus for rasterizing a digital sample stream by producing histograms for each of a plurality of time slices forming a display frame. Time slice histograms for at least one display frame are stored in a circular memory buffer and provided to a display raster for display. The first time slice displayed optionally comprises that time slice temporally associated with a trigger condition.

  • Patent number: 6662740
    Abstract: An adjustable boat whip assembly for maintaining a boat in spaced relation to a dock includes a boat whip, an elongate base member secured to the dock, a whip support member having a receptacle for receiving the boat whip in a generally upright position, and an interconnecting structure for attaching the support member to the base member so that the support member can move along the length of the base member. A fastener is further provided for locking the support member to the base member. In one embodiment of the invention, the base member of the boat whip assembly includes a structural tubular body having an upwardly extending top flange that is received in a slot provided in the support member. The arrangement is such that the support member is movable along the length of the base member.

  • Patent number: 6388595
    Abstract: The subject invention addresses the problem of aliasing in subsampled data by adding dither to the timing of the subsampling of the data. The subject invention solves a speed problem caused by delays in modifying (i.e., dithering) the A/D converter sampling clock. It is herein recognized that to maintain a high acquisition rate one should randomly select (i.e., dither) samples after demultiplexing the data into a wider and slower stream of samples, rather than attempting to modify the high speed A/D converter sampling clock.
