  • Patent number: 9066679
    Abstract: A real-time signal processing technique for ultrasonic imaging of tissue vibrations for localizing the source of a bruit in a 2D image with respect to the anatomy and/or for obtaining simultaneous information about vibrations and the underlying blood flow. The bruit can be quantitatively assessed using an ensemble of ultrasound echoes. Signal processing enables estimation of wall displacement and the display of time-resolved vibration spectrum. Vibrations are detected and color-coded according to their amplitude and frequency and overlaid on the B-mode and/or color-flow image in real time. Proposed vibration imaging algorithms use data acquired during conventional ultrasonic color-flow imaging and the clutter signal, normally suppressed in color-flow imaging, to detect and characterize tissue vibrations. Three vibration imaging algorithms based on parametric modeling of vibrations and other criteria distinguish between clutter, blood flow, and vibrations.

  • Publication number: 20110043683
    Abstract: Disclosed herein are systems and methods that divert images for image capture devices. An image diversion system includes a housing, at least one reflective surface within the housing, and a mounting mechanism. The housing is adapted to mount onto an existing image capture device. The at least one reflective surface can divert the image that is captured by the image capture device when the housing is mounted on the image capture device. Another image diversion system also includes at least one total internal reflection (TIR) element that can divert the image that is captured by the image capture device when the housing is mounted on the image capture device. A method provides a housing, at least one reflective and/or refractive surface within the housing, and a mounting mechanism.

  • Publication number: 20020069104
    Abstract: A system for generating authorization codes, such as personal identification numbers, at the point of distribution of certificates of value on which the authorization codes are to be printed or otherwise encoded. Because the authorization codes are generated in real time, there is no need to store and safeguard an inventory of preprinted certificates, or even an inventory of activated authorization codes. The principles of the invention apply both to systems for generating incentive award certificates and to systems for generating purchased certificates of value. The incentive awards or certificates of value are tokens of prepayment for a service, such as long-distance telephone service or other service. The authorization codes generated for inclusion with the value certificates are unique and seemingly random. They are generated by taking a non-random unique code, such as a sequence code, and encrypting it to obtain seemingly random, but unique, authorization codes.

  • Patent number: 6042556
    Abstract: Phase of each transducer element of a high intensity focused (HIFU) transducer array is controlled to compensate for phase change introduced by varying velocity through differing tissue along a path towards a treatment volume. The echo of a specific harmonic of ultrasound pulses of moderate intensity and less than HIFU intensity are used to measure the propagation path transit time of each HIFU transducer element that will converge in a treatment volume through nonhomogeneous tissue. The moderate intensity is outside the linear region between molecular velocity fluctuations and pressure fluctuations. Thus, specific harmonic echoes are distributed in all directions from the treatment volume. Temporal delay in the specific harmonic echoes provide a measure of the propagation path transit time to transmit a pulse that will converge on the treatment volume.

  • Patent number: 5909793
    Abstract: The present invention uses promotional coins to encourage use of a coin counter. The promotional coins are minted in such a way that an unaided human is not likely to distinguish a first prize coin from other promotional coins, e.g., because all promotional coins have substantially identical size, weight and appearance. Due to the apparent similarity between the various promotional coins, the participant is required to use a coin counter to distinguish prize coins from other promotional coins. In one embodiment, the promotion is implemented using a coin counter. Promotional coins are distributed to potential customers who are thereby enticed into using the coin counter as desired. The coin counter accepts and discriminates among government-minted coins of multiple denominations, various promotional coins and unknown debris.

  • Patent number: 5289820
    Abstract: Quadrature phase signals (I and Q) from a pulsed Doppler medical instrument are analyzed to detect phase changes of consecutive echoes from tissue at a depth of interest. Such phase changes are analyzed to determine tissue displacement. Relative displacements at different depths are examined to detect tissue expansion and contraction. The area of the uterus of a pregnant female can be scanned and the frequency of tissue displacement or expansion and contraction examined to determine pulsations due to blood supplied by the fetal heart and/or pulsations due to blood supplied by the maternal heart. Conventional M-mode or B-mode images can be colorized differently for different frequencies of tissue displacement.

  • Patent number: 4757714
    Abstract: A transmitter is mounted for movement with a skier or other self-propelled sportsman and transmits ultrasonic or electromagnetic waves toward the stationary medium over which the skier or sportsman is moving. An element of the same transmitter or a separate transducer detects waves reflected from the stationary medium. A computer calculates the speed of the skier or sportsman from the Doppler shift of the reflected waves and actuates a readout unit to indicate the speed to the skier or sportsman. The readout system has a head-mounted display including a character generator and a semitransparent reflector in which the character generator is viewed so that the speed indication appears superposed over the normal background in the viewing direction.
