  • Object detector and associated driving device for a medical diagnostic apparatus
    Patent number: 5883935
    Abstract: 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..sub.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.
