Patent number: 8617077Abstract: A high power ultrasound application device (1) is provided which comprises a hand-held applicator (3). The applicator comprises a converter element (5) for converting electric signals into ultrasound waves; a treatment head (6) configured to apply ultrasound waves from the converter element to a subject to be treated; a handle (8) for holding and manipulating the applicator; and an oscillator circuit (9) arranged in the applicator and comprising one or more electronic components (10A, 10B) configured to be energized by a power source and to generate an output signal to drive the converter element. The oscillator circuit is in thermal contact with the handle, and the handle comprises a heat conductivity and thermal coefficient such that, when manually held by an operator in normal use, a heat conductive channel is provided between at least a portion of the circuit and the operator.Type: GrantFiled: March 18, 2011Date of Patent: December 31, 2013Assignee: Enraf-Nonius B.V.Inventors: Johannis van Groningen, Petrus Alfonsus Maria Roodink

Patent number: 8409100Abstract: An ultrasound treatment head for an apparatus for treating a patient with ultrasound comprises at least one active element for converting an electric signal into ultrasound and a vacuum cup having an upper part and a lower part. The active element is mounted in the upper part and the vacuum cup provides a vacuum chamber with a holding space for a gel pad. The upper part is adapted to act as a spring suspension for the active element to lower the active element into the lower part. The active element is provided with a positioning ring protruding with respect to the active element. This positioning ring determines the location of the gel pad within the holding space.Type: GrantFiled: July 20, 2009Date of Patent: April 2, 2013Assignee: Enraf-Nonius B.V.Inventors: Theodorus Johannes Virginia Caberg, Ronald Scharp, Johannis Van Groningen

Patent number: 6411676Abstract: A method for determining the parameters of a unit cell of a crystal structure using diffraction is presented. The method includes the steps of repeatedly rotating the crystal at a predetermined angle, while the crystal moves in relation to a detection surface and measuring the position of radiation reflected from the crystal. The resulting combined measurements are utilized to accurately determine the unit cell dimension and orientation of the crystal.Type: GrantFiled: December 22, 2000Date of Patent: June 25, 2002Assignee: Nonius B.V.Inventors: Robertus Wilhelmus Hooft, Albert Jozef Duisenberg, Antonius Matthias Schreurs
