摘要： An apparatus comprising a conduit clamping device with a closing mechanism for closing and opening passage of fluid or air in a flexible conduit is disclosed. The apparatus comprises a movable arm or disk that is connected to a manipulation arm or a knob; a conduit in form of a tube, that is laid flat against an abutment or protrusion; and a guide structure that constrains the movable arm or disk between the guide structure and the tube and being designed such that movement of the arm or disk will control the compression of the tube.

摘要： The invention relates to an optical measuring system (1) and to a method for measuring an object (9) in a three-dimensional manner. The measuring system (1) has at least one lens array (5), a first convex lens (6) arranged downstream, a second convex lens (8) which is arranged further downstream and which faces an object (9) to be measured, and additionally a means (7) which absorbs incident light or deflects incident light out of the illuminating beam path and which is arranged upstream of the second convex lens (8) or on the second convex lens (8) on a second convex lens (8) face facing the first convex lens (6) in the region of the optical axis (10).

摘要： A method for controlling a magnetostrictive ultrasonic transducer of the type used in a magnetostrictive ultrasonic dental scaler includes generating a drive signal for a resonant circuit using a full bridge synchronous class D amplifier. The electrical signal output by the resonant circuit drives an excitation coil that generates an electromagnetic field that causes the magnetostrictive ultrasonic transducer to vibrate. A feedback wire is rendered unnecessary by measuring current and voltage outputs of the resonant circuit and quadrature sampling the measured current and voltage outputs at the same sampling rate as used for the generation of the electrical signal by the resonant circuit. A pulse width modulated signal is generated from the quadrature sampled sensed current and voltage that represents a pulse train approximation of a sine wave of the drive signal for, in turn, being applied to the full bridge synchronous class D amplifier to generate the drive signal for the resonant circuit. Changes in the pulse widths of the pulse train change the amplitude of the drive signal.
