A medical device includes an energy storage unit that is configured for being supplied with solar energy. The medical device is configured for an evaluation of a charging state of the storage unit according to a medical workflow and for the output of information related to the result of the evaluation or a signal related to the evaluation. A supply of energy is provided during the workflow.

Solar powered operation of medical devices

The invention specifies a holding apparatus comprising a support element and a circuit board. A trench for receiving the circuit board is embodied in the support element. At least one first clamping element is arranged on one or both longitudinal sides of the circuit board and/or at least one second clamping element is arranged in the trench. As a result, the circuit board received by the trench is fixed in the trench in a clearance-free fashion.

Holding apparatus

A retaining facility for clearance-free fixing of a printed circuit board onto a one-dimensional curved surface is provided. In the direction of curvature of the one-dimensional curved surface, a tensile or compressive force acts on the printed circuit board or on at least one first connection device connected to the latter, with the printed circuit board being bent and pressed onto the curved surface. In this way the printed circuit board is held solidly and with little vibration on the surface even when acted on by centrifugal forces.

A device () comprises a container () for a liquid coolant () that is disposed between the axis () and the surface () facing the axis to co-rotate with the surface. The device is further provided with an atomizer nozzle () of the container, facing the surface, from which the coolant is discharged during rotation of the container due to the centrifugal force (F) acting upon the coolant of the container in the form of an atomized jet () that strikes the surface. The device cools a surface of an electronic device () that runs hot, the electronic device supplying the X-ray source of a computer tomograph with power and rotating about the axis of the gantry () of the tomograph.

A high-voltage generator for high d.c. voltages, particularly for feeding an x-ray tube has secondary windings applied by a printed technique on printed circuit boards that are held at a common printed circuit board, and which are interconnected thereto in printed technique with components for producing the high-voltage.

High-voltage generator

A three-phase rectifier circuit for a capacitive load wherein only small current harmonics occur has, at the rectifier input, an inductance and a capacitor arrangement that compensates the reactive power of the inductance. The capacitors can be individually switchable, for the regulation of the rectifier output voltage.

Three-phase rectifier circuit having capacitors which are switched into

A high-frequency x-ray generator having low high-voltage ripple at the x-ray tube with a small amount stored energy in the high-voltage circuit and low drive frequency has a series of secondary windings each connected to a high-voltage rectifier having a capacitor connected in parallel. These capacitors are connected in series for forming the x-ray tube voltage. Each secondary winding has a primary winding allocated to it. The primary windings in combination with delay capacitors form a delay line in which a traveling wave is generated by a primary voltage source.
