Abstract: A medical device for narrowing or closing an anatomical channel includes a band part (1) which can be placed around the body tissue (2) surrounding the anatomical channel and which can be closed to form a ring that encloses a through-opening (6) for the body tissue, wherein the band part (1) has a hollow chamber (3), and wherein the through-opening (6) can be made smaller by introducing a fluid into the hollow chamber (3). The medical device moreover includes a pump unit (10) which serves to convey the fluid and which has an electric drive (15) controllable by an electronic control system of the device, wherein a pressure value corresponding to the pressure of the fluid in the hollow chamber (3) or dependent on this pressure can be detected by the electronic control system. The device moreover has an air pressure sensor (23) for detecting the atmospheric pressure.

Abstract: A camera system for capturing a substantial portion of a spherical image, the capturing being triggered adjacent the highest point of a free, non-propelled trajectory, comprising two or more camera modules, the two or more camera modules being oriented with respect to in each such camera module optical main axis in two or more directions different to each other, at least one control unit that connects to the two or more camera modules, and a sensor system including an accelerometer, wherein the camera system does not comprise a position detector.

Abstract: A system is provided for use during a medical procedure. The system has at least one sensing device holder configured to hold a radiation sensing device, a ring guide, and a rod which connects the holder to the ring guide. The ring guide includes a ring having a central opening and first and second connecting portions extending outwardly therefrom. The ring defines horizontal and vertical axes which pass through an axial centerline of the ring guide. Each connecting portion has a channel which accepts the rod therethrough and which is parallel to the axial centerline. The channel of the first connecting portion intersects the horizontal axis, and is offset from the vertical axis. The channel of the second connecting portion is offset from the horizontal and vertical axes. The rod can be attached to either of the connecting portions.

Abstract: This optoelectronic, finger-operated keyboard for use in industrial measurement equipment is designed to achieve an optimum signal-to-noise ratio and minimize the drop in the intensity of the infrared emitters during the service life of the measurement equipment. The keys for generating respective associated operation signals (n1, n2, n3) have an infrared-transmitting cover (1), one infrared emitter (3) per key disposed at the inside (12) of the cover and emitting light collimated virtually perpendicular thereto, one infrared detector (4) adjacent to each infrared emitter which is separated from the latter by a shield (5) opaque to infrared and is pointed at the cover, said infrared detector being located within the main radiation range of the infrared light emitted by the infrared emitter and scattered at a finger (2) but outside the infrared light reflected from the outside and/or inside of the cover.
