Abstract: A sensor system comprises a sensor that outputs sensor data during operation; a web-based user interface for displaying the output sensor data on an end device and for transmitting control instructions of a user from the end device to the sensor; and a data recorder that is connected to the sensor and that is configured to receive sensor data output by the sensor and to store said sensor data on a storage medium. The data recorder has a switching device that is configured to forward sensor data received from the sensor to the web-based user interface and/or to forward control instructions received from the web-based user interface to the sensor.

Abstract: The present disclosure relates to a procedure for generating fluoroscopic images for the reconstruction of a volume in a flat object using an X-ray system, which has three imaging components, namely a tube, a detector and a manipulator, located between them, on which the object is fixed. The object extends multiple times further in two dimensions than in its third dimension. The tube has a focus, which, in a central position of the tube, forms the coordinate origin of a Cartesian coordinate system, and which emits an X-ray. The vector from the tube through the volume forms the x axis of the coordinate system and the z axis is perpendicular to a vector formed through the thickness. The manipulator is rotated about a rotational axis, which is perpendicular to the x axis, runs parallel to the z axis and is displaceable parallel to the x axis.

Abstract: A sensor for monitoring a zone with regard to the presence of at least one object includes a transmission device, a reception device and an evaluation device. The transmission device emits transmission signals into the zone to be monitored. The reception device receives detection signals that include those transmission signals that are reflected or remitted in the zone to be monitored. The evaluation device is configured to determine at least one measurement variable based on the detection signals related to at least one dimension of an object in the zone to be monitored, to determine and output an occupied state of the zone to be monitored if the at least one measurement variable is greater than an entry threshold value, and to determine and output a free state of the zone to be monitored if the at least one measurement variable is smaller than an exit threshold value.

Abstract: A bicycle battery assembly comprises a bicycle frame tube, such as a down tube. A battery is adapted to be inserted through a battery opening in the longitudinal direction of the bicycle frame tube. For allowing for a simple fixing of the battery to the bicycle frame tube, in particular by means of screws, an installation aid is connected to the battery and/or the bicycle frame tube, in particular in the area of the battery opening. The installation aid allows for an easy installation since in particular screw holes in the bicycle frame tube are flush with threaded bore holes in the battery.

Abstract: A bicycle frame tube which is in particular a down tube of a bicycle frame comprises a battery opening for inserting or removing a battery. Inside the bicycle frame tube a holding element for holding the battery is arranged. The holding element is at least partially elastically deformable, wherein the holding element in particular comprises two abutment elements which are elastically deformable.

Abstract: A method for the reconstruction of a test part in an X-ray CT method in an X-ray CT system, which has an X-ray with a focus, an X-ray detector, and a manipulator which moves the test part within the X-ray CT system. To generate recordings of the test part in various positions, the manipulator travels a predefinable parameterizable path-curve and makes recordings at triggered positions. For each recording, the position of the manipulator is determined and the respective associated projective geometry is calculated. Thereafter, a further path curve is followed having different parameters from the preceding path curve. The path curve is determined iteratively by means of an optimization algorithm, at the value of which the quality function is minimal. For each test part, a CT reconstruction is carried out by means of a suitable algorithm with reference to the allocation of the individual recordings to the respective projective geometry.
