Abstract: 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.

Abstract: 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.

Abstract: An explosion-protected device (1) comprises a deformable interior body (20) that comprises at least one line channel (30, 31) extending along a longitudinal axis (L) through the interior body (20) for a line. The line extends through the at least one line channel (30, 31). The interior body (20) is encompassed by a housing (2). The housing (2) is divided into an incoming section (3), an outgoing section (4) as well as a middle section (5) disposed between the incoming section (3) and the outgoing section (4). A spring element (25) is provided which is disposed in the middle section (5) and exerts pressure onto the interior body (20).

Abstract: 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.
