摘要： An apparatus for medical diagnosis and/or therapy which includes an electromagnetic proximity sensor (20-1, 20-2, 20-3, 20-4) which detects the presence of an object (for example, 28) directly in front of the sensor. By coupling the main drive directions (34-1, 34-2, 34-3) and (34-4) to the proximity sensors in such a manner that each main drive direction (for example, 34-4) substantially halves the exterior angle ( alpha 4) between the two neighbouring proximity sensors (20-1, 20-4) and by inhibiting the displacement in the associated main drive direction (34-4) by these two neighbouring proximity sensors, it is achieved that all clearing movements remain possible and all movements leading to collisions are inhibited.

摘要： An apparatus for medical diagnosis and/or therapy includes an electromagnetic obstacle sensor in order to prevent collisions with, for example, a patient to be examined. The sensor is constructed so as to include a radiation transmitter and a radiation receiver in the form of capacitive electrodes (16 and 18), respectively, whereto electronic circuits (26 and 28) for signal processing are connected. In order to enable the electrodes (16 and 18) and the electronic circuits (26 and 28) to be checked for correct operation, a test electrode (14) is connected between the transmitter electrode (16) and the detection electrode (18), which test electrode can be connected, if desired, to a point (32) of fixed voltage via a controllable switch (34). The presence of an obstacle is thus simulated. The output signal of the electronic circuits (26 and 28) can be checked to determine whether this output signal corresponds to the situation in which an obstacle is present.

摘要： An apparatus for medical diagnosis and/or therapy, including an electromagnetic obstacle sensor. Due to variations of the ambient temperature and humidity and/or due to the hanging of, for example, a cloth around the sensors (16, 18), drift of the zero point of the control may occur, so that the approaching of an obstacle by a movable part (6) of the apparatus could be incorrectly interpreted by the apparatus. In order to compensate for such drift there is provided a control unit (25) for automatically controlling the output signal V0 of the receiver (27) back to the zero value in the absence of an object in the vicinity of the movable part (6). This control preferably takes place at a comparatively high speed when a cloth or moisture is moved into the vicinity of the sensors, and at a comparatively low speed upon removal of the cloth or the moisture. As a result, the nature of the movement of the drive is maintained for some time after the displacement of the movable part, thus contributing to the ease of operation of the apparatus.
