摘要： A 1D ultrasonic converter unit having at least three ultrasonic converters and a control unit for individually controlling each ultrasonic converter, wherein each ultrasonic converter has a housing, a piezoelectric body, and a sound decoupling layer for decoupling sound waves in a gaseous medium, is embedded in a common carrier structure, and emits and/or receives the same frequency between 20 kHz and 400 kHz. Each ultrasonic converter has one sound channel having an input opening associated with one sound decoupling layer, and an output opening. The output openings are arranged along a line, a distance between two adjacent output openings corresponds at most to the whole or half the wavelength of the sound frequency and is smaller than the distance of the input openings.

摘要： A current output apparatus adapted for electrical connection to a load to output an electrical current thereto. The apparatus comprises a current output terminal for connecting to a first terminal of the load to pass an electrical current thereto. A current input terminal is provided for connecting to a second terminal of the load to receive said electrical current returned from the load. A voltage regulator is operable to supply to the current output terminal an electrical voltage regulated to differ from an electrical voltage applied to the current input terminal by an amount sufficient to cause said electrical current to flow from the current output terminal to the current input terminal via the load. The voltage regulator is operable and arranged to supply to the current output terminal an electrical voltage of positive polarity or of negative polarity for supplying said electrical current to a load presenting to the current output terminal a voltage of positive polarity or of negative polarity, respectively.

摘要： A clamping device with a housing, with a piston with piston rod running in the housing, and with a monitoring unit arranged at least partially in the housing, wherein the monitoring unit includes at least two sensor units. The sensor units are spaced apart from one another along a longitudinal axis of the piston rod, and are arranged at a distance from the piston rod. The piston and the piston rod, and a metallic signal transmitter arranged on the piston or on the piston rod, are movable in a positively driven manner between a first end position and a second end position. The first sensor unit is arranged at the first end position of the signal transmitter, and the second sensor unit is arranged at the second end position of the signal transmitter. Each sensor unit has a first and second sensor and includes an induction coil and an oscillator.

摘要： There is provided a power conditioning circuit including positive and negative power input nodes. An inductor includes a first terminal connected to a positive power input node and a second terminal connected to a positive power output node, the inductor allowing the voltage at the positive power output node to be modulated by data that is sent through a communication interface. A first node is present between the second terminal of the inductor and the positive power output node, and a clamping circuit is connected at the first node to a second node. The clamping circuit is configured to clamp a voltage increase across the inductor to less than a maximum increase. The second node is configured to be continuously held at a voltage higher than the voltage of the first terminal of the inductor.
