Abstract: Smooth vertical movement of a graphics image on a raster display is performed via color palette manipulation at any speed. A color look-up table has a color palette position for each color within the graphics image plus unassigned color palette positions that are assigned to pixels on the top of horizontal color edges of the graphics image. During movement of the graphics image the color values of the assigned color palette positions are updated each display cycle as a function of a desired rate of vertical movement of the graphics image.

A second polarizer is over the electro-optic layer and transmits only light that is polarized in the second state.

Abstract: A dynamically variable anti-aliasing filtering system calculates on a local basis the compression factors (Cf) present in an image that is being mapped from a two-dimensional source image through a three-dimensional space and into a two-dimensional target image, the apparatus implementing a linear equation of the form:Cf=A*X.sub.s +B*Y.sub.s +Cwhere, X.sub.s and Y.sub.s are, respectively, the horizontal and vertical coordinates of pixels in the source image, and A, B and C are precalculated (each field or frame) constants that depend on the transform matrix function F. A total of four compression factors are required, one for control of horizontal luminance filtering, one for control of vertical luminance filtering, one for control of horizontal chrominance filtering and one for control of vertical chrominance filtering. Three dual accumulator circuits are used to implement the linear equation in X.sub.s and Y.sub.s for three different sets of A, B and C.

Abstract: A time-interleaved method for efficient operation of an acoustic wave sensor array couples each sensor repetitively and one at a time via a digitally-addressable analog switch, or multiplexer, to a single oscillator driver to form an oscillation circuit. A frequency of oscillation for each acoustic wave sensor is determined. The frequency for each acoustic wave sensor then is converted into a measurement value for the parameter to which each acoustic wave sensor is sensitive.

Abstract: A first subset of components of a first set of pairs of complementary differential electrical signals representative of a numerical value expressed in a multi-bit thermometer code, is processed in accordance with a first set of Boolean functions to produce a first set of output electrical signal components , and a second subset of components of the first set of pairs of complementary differential electrical signals is processed in accordance with a second set of Boolean functions to produce a second set of output electrical signal components. The first and second subsets and the first and second sets of Boolean functions are such that the first and second sets of output electrical signal components when combined form a second set of pairs of complementary differential electrical signals representative of the same numerical value expressed in a second multi-bit code with fewer bits than the multi-bit thermometer code.

Abstract: Apparatus for processing a video signal representing distribution of optically-perceptible information over a video raster includes a video combiner for receiving an input video signal and a delayed video signal and combining the input video signal and the delayed video signal to provide an output video signal. A memory receives and temporarily stores the output video signal and provides the delayed video signal, and read/write circuits access the memory so that pixels of the output video signal are spatially translated relative to the video raster when the output video signal is written into and read from the memory.

Abstract: Time warping for video viewing is achieved by providing a random access dynamic buffer for a video signal from a selected video channel. The video signal is continuously written into the dynamic buffer in a recirculating fashion, and may be read out on a random access basis so that the viewer may control the realtime video viewing in the same manner as controlling a video cassette recorder up to the duration of the video signal stored in the dynamic buffer. In addition the viewer may view the video at various speeds and skip to any point in the stored information. Portions of the video signal in the dynamic buffer may be stored in a static buffer or transferred permanently to a video cassette recorder for subsequent manipulation by the viewer. To expand the capacity of the dynamic buffer a compression circuit may be provided for compressing the video signal before being written into the dynamic buffer.

Abstract: An optical power conversion circuit converts an optical energy signal from an optical source, such as a laser diode, to a regulated D.C. electrical voltage using a single photodetector. A buck-boost circuit uses electrical current from the photodetector in response to the optical energy signal to store energy in an inductor during one polarity of a control signal, and transfers the energy from the inductor to an output capacitor during the other polarity of the control signal. The duty cycle of the control signal determines the regulated D.C. electrical voltage. A switch drive circuit generates the control signal as a pulse width modulated signal from the regulated D.C. electrical voltage and a reference voltage. The control signal is A.C. coupled to a pair of FET switches in the buck-boost circuit to alternately energize and charge the inductor and capacitor respectively.

Abstract: A programmable analog multi-channel probe system is embedded within a device under test for coupling test points to external measurement points of the device under test. Programmable input buffer amplifiers are coupled to the test points to couple the data at those points to their outputs when enabled.

Abstract: An operator interface for a video editing system provides a visual sense of the content of video sequences, as well as their length, while also providing enhanced interactive control of locations and time alignments of the video. As the video sequence is processed into the system, a small but representative sample of each frame is saved in a local memory, while the video itself is stored in mass storage. These samples are used to provide a video pictorial timeline of the underlying stored video. The location of an operator's view into the video sequence is controlled by a cursor's movement along a detailed video pictorial timeline, a reverse motion area and a forward motion area to provide VTR control for location changes on the video tape. The cursor's movement can be controlled by a mouse or a knob. Icons, either static or dynamic, are produced within the motion areas to indicate the amount of selected velocity.
