  • Method and device for transferring the wave front of a primary light pulse to a secondary light pulse
    Publication number: 20050018261
    Abstract: The invention relates to a method for transferring the wave front of primary light pulses with a specifiable first pulse duration and/or energy to secondary light pulses with a specifiable second pulse duration and/or energy. For an easy realization of a wave front transformation of this type, it is suggested according to the invention to store respectively in a first time segment the wave fronts of the primary light pulses with the aid of reference light pulses as spatial hologram in a holographic memory. In a following second time interval, this stored, spatial hologram is then read out with the aid of reconstruction light pulses, having the second pulse duration and energy, wherein the reconstruction light pulses for reading out the hologram have the same wavelength and wave front as the reference light pulses.

  • Composite Adhesive
    Patent number: 6841615
    Abstract: A composite adhesive featuring a matrix phase that includes a cyanate ester and a filler or reinforcement phase that includes a plurality of bodies of at least one material comprising a high shear strength and/or high modulus material. Preferably, the filler also possesses at least one of high thermal conductivity and low coefficient of thermal expansion. Unlike certain commercially available cyanate esters, those of the instant invention substantially maintain or even increase in strength upon addition of the filler to the system. The instant composite adhesives may also display reduced coefficients of moisture expansion relative to the unfilled or “neat” resin. Such a composite adhesive is extremely useful for joining articles where high strength and minimal swelling in moist environments are required, such as in the precision equipment industry.

  • Audio waveform cueing for enhanced visualizations during audio playback
    Publication number: 20040264917
    Abstract: Cues, or indicators, are associated with an audio waveform. The cues can be placed or arranged automatically, or manually by a human operator. During playback, the cues are detected by a playback device and can be used by a visualization to correlate images, animation, colors, or other characteristics of the waveform to a visual presentation. Different cues correspond to different basic song characteristics such as percussion or beat. Instrument cues are used for noticeable instrument phrases, notes, or effects. Instrument solo cues are used to indicate the start and end of instrument solos or passages that stand out. Vocal cues include a range of coarse, medium or fine vocal tracking to provide cues for, e.g., mere presence of vocals, to close tracking of words, melody and emotional delivery. A playback engine uses the cues to create a visualization.

  • Viscometer sag test shoe
    Publication number: 20040261507
    Abstract: Methods and apparatus for measuring sag properties of a drilling fluid using a rotary viscometer. An insert, or shoe, is placed at the bottom of the heat cup containing the fluid to be tested. A rotating cylinder is disposed within the fluid and solid particles are allowed to settle toward the bottom of the heat cup. The shoe incorporates a curved and inclined upper surface that directs the settled particles toward a well non-centrally located in the shoe. As the test is performed, fluid samples can be withdrawn from the well and analyzed. The samples can then be returned to the well and the test continued. The insert concentrates the settled solids into a single location, which increases the sensitivity of the test and provides a location for sample acquisition that is easily and repeatedly located, which allows for improved correlation with laboratory and flow loop results.
