Abstract: A functional component is arranged in the radiation region, configured to move in a movement direction and has at least one conductive region. A position sensor has an electrical coil arrangement configured to provide a summation voltage based on sensing of the at least one conductive region. The electrical coil arrangement includes an exciter coil configured to provide an alternating magnetic field, and two series-connected sense coils configured to sense at least part of the alternating magnetic field. The sense coils and the exciter coil are arranged such that the summation voltage across the sense coils depends on a position of the functional component relative to the position sensor. The apparatus is configured to determine a position signal based on the summation voltage, the position signal relating to the position of the functional component relative to the position sensor.

Abstract: A method is for detecting high-voltage flashovers in X-ray equipment including an X-ray emitter and a high-voltage supply. The X-ray emitter has an X-ray tube, surrounded by an insulating medium; and the high-voltage supply has a high-voltage generator and a cable. The cable is at least part of a connecting passage between the high-voltage generator and the X-ray tube. During normal operation of the X-ray equipment, an interference pulse, which occurs due to the high-voltage flashover in the connecting passage, is detected and evaluated with the aid of a measuring device, including a measuring element. As such, an assessment of the condition of the X-ray emitter and of other high voltage-carrying components, and measures that follow, are made using the evaluated interference pulse.

Abstract: A computed tomography device includes a slipring for rotational transmission and a feed line. The slipring is arranged to be rotatable relative to the feed line. Two sliding contact elements are further included, forming sliding contacts between a slideway of the slipring and the feed line, the two sliding contacts being connected in parallel with one another and electrically conductively connected together via at least one portion of the slideway and via at least one portion of the feed line. Finally, the computed tomography device includes a measuring apparatus, configured to acquire a measured value dependent on a resultant inductance between the two sliding contact elements; and at least one processor, configured to determine an operating state of the two sliding contacts based upon the measured value.
