  • Patent number: 11061514
    Abstract: A method provides a touchable user interface based on a surface. The surface supports direct human-machine interactions as conventional touch-sensitive platforms. According to implementations of the method, a mechanical actuator-sensor assembly is arranged at any type of object, and the assembly generates and senses the mechanical wave propagating in the object. In this way, a “touchable” surface can be created.

  • Patent number: 10794865
    Abstract: An apparatus and method for the separation of an oil-water mixture into its components are described. An acoustic radiation force moves oil droplets to the nodes of an acoustic standing wave generated in a vertical column containing the oil-water mixture. Once the droplets are sufficiently close together, attractive forces become dominant and the droplets may coalesce to form larger droplets, which have greater buoyancy, and separation of the mixture into a layer of oil and a layer of water occurs, not possible by simple gravitational separation. Acoustically-driven oil-water separation may be used for water-cut measurements in oil production wells, since separation of the oil from the water permits accurate sound speed measurements to be made for both the oil and the water, thereby allowing frequent in situ calibrations of the apparatus to determine whether sound speed measurements on the mixture are accurate in the event that one or both of the mixture constituents is changing.

    Abstract: A keypad with a plate and distinct keys that move relative to the plate to generate an acoustic signal for acoustic pulse recognition (APR). Each key represents an input value and is structured to contact the plate at a region smaller than an upper surface of the key where a finger or a thumb comes into touch. The contact region of the plate coming into contact with an individual key is small relative the upper surface of the key, and hence, acoustic signals generated in response to the touch of the same key has less variance compared to acoustic signals generated in response to a direct touch of the plate by a finger or a thumb. As a result, the localization of the touch using APR can be more accurate compared to direct touch of the plate by a figure or a thumb.

  • Patent number: 8578777
    Abstract: A quantitative evaluation method, a method for manufacturing a silicon wafer, and a silicon wafer manufactured by the method, enabling more efficient evaluation of the concentration of atomic vacancies existing in a silicon wafer. The quantitative evaluation method includes steps of: oscillating, in a state in which an external magnetic field is applied to a silicon wafer (26) while keeping the silicon wafer (26) at a constant temperature, an ultrasonic wave pulse and receiving a measurement wave pulse obtained after the ultrasonic wave pulse is propagated through the silicon wafer (26) for detecting a phase difference between the ultrasonic wave pulse and the measurement wave pulse; and calculating an elastic constant from the phase difference. The external magnetic field is changed to calculate the elastic constant corresponding to a change in the external magnetic field for evaluating a concentration of atomic vacancies in the silicon wafer (26).

  • Patent number: 8499636
    Abstract: An ultrasonic diagnostic apparatus that performs high acoustic pressure and low acoustic pressure ultrasonic transmissions by switching at predetermined timing in the enhanced ultrasonography, and displays concurrently a replenishment image obtained through the low acoustic pressure transmission in real time like a moving picture, and a pre-flash image obtained through the low acoustic pressure transmission immediately before switching to the high acoustic pressure transmission like a still image to allow the operator to understand the structure at the level of capillaries. It is also possible to display a selected image obtained through the low acoustic pressure transmission at an arbitrary timing instead of the pre-flash image.
