  • Patent number: 8055077
    Abstract: A realtime display compression for a waveform image uses a priority basis for combining groups of pixels when producing a compressed waveform image in order to preserve intensity information. As an example successive lines of data for the waveform image are demultiplexed into line buffers in a circulating manner, the number of line buffers being a function of the maximum desired integer compression ratio. The outputs from the line buffers are aligned and the corresponding pixels are combined according to a desired compression ratio, one output line for each integer compression ratio. The appropriate compressed line is selected as the output line according to the desired compression ratio, with the totality of the output lines forming the compressed waveform image.

  • Patent number: 7516028
    Abstract: A test and measurement instrument includes a memory configured to store a digitized signal, a display configured to display the digitized signal, a mark interface configured to generate a mark creation signal, a processor coupled to the memory, the display, and the mark interface. The processor is configured to identify a feature of the digitized signal and create a mark indicating the feature and the digitized signal in response to the mark creation signal.

  • Patent number: 7227549
    Abstract: A method of indicating and manipulating a zoom region of a waveform being displayed includes a zoom region indicator. The zoom region indicator has an associated marker that spans the zoom region but is never less than a minimum span to allow ease of identifying or locating the zoom region on the displayed waveform. Manipulating the associated marker with a pointer device causes the zoom region to move accordingly along the displayed waveform. The portion of the displayed waveform that is within the zoom region is displayed as a zoomed waveform on the display.

  • Patent number: 4509744
    Abstract: An aquatic exercise device for use in a swimming pool or the like comprising a substantially rectangular, flat rigid fluid resistance member having an adjustable substantially U-shaped hand gripping member disposed in fixed spaced relation relative to the surface of the substantially rectangular flat rigid fluid resistance member by a pair of substantially parallel interconnecting members and a wrist guide including a flat rigid stability member extending in a coplanar relation relative to the substantially rectangular flat rigid fluid resistance member to engage the user's wrist and a substantially J-shaped axial alignment member extending from one longitudinal edge of flat rigid stability member to receive the user's wrist such that the user grasps the adjustable substantially U-shaped hand gripping member while placing his wrist within the substantially J-shaped axial alignment member whereby the user moves the aquatic exercise device through the water to create a significant resistance on the substantiall
