  • Publication number: 20150277420
    Abstract: The present invention relates to a moving equipment, such as in a medical examination system. In order to provide a facilitated way of moving equipment with high accuracy, a driving device (10) for moving equipment is provided, comprising a motor-driven positioning unit (12), a central processing unit (14), and a user interface (16) with at least one sensor unit (18). The motor-driven positioning unit is configured to carry out a movement (M) of movable equipment. Further, the central processing unit is configured to control the movement of the equipment provided by the motor-driven positioning unit. The at least one sensor unit comprises at least one touch sensitive area (20), and the at least one sensor unit is configured to provide control signals (22) to the central processing unit in dependency from a force (F) applied by a user to the at least one touch sensitive area. Still further, the at least one sensor unit is configured to be fixedly attached to the movable equipment.

  • Publication number: 20150209540
    Abstract: The present invention relates to a patient interface and a patient interface system comprising a responsive material and a method for preventing the formation of red marks due to wearing a patient interface (10) that is pressing against the skin of a patient (14) for a longer time and/or for reducing air leakages of the patient interface (10) that may result from an unintended shift of the patient interface (10) on the patient's face. The responsive material is configured for alternating the pressure exerted by the cushion element (18, 26) on the patient (14), and/or the area on the patient where the pressure is exerted by the cushion element in response to a physical quantity acting on the responsive material. The formation of red marks and of air leakages can be reduced or even avoided by means of the responsive material.
