Abstract:
A method for controlling a device, in particular a prosthetic hand or a robotic arm, includes using an operator-mounted camera to detect at least one marker positioned on or in relation to the device. Starting from the detection of the at least one marker, a predefined movement of the operator together with the camera is detected and is used to trigger a corresponding action of the device. The predefined movement of the operator is detected in the form of a line of sight by means of camera tracking. A system for controlling a device, in particular a prosthetic hand or a robotic arm, includes a pair of AR glasses adapted to detect the at least one marker and to detect the predefined movement of the operator.

Abstract:
The invention relates to a method for determining properties of a pipeline, in particular the position of a branch of a sewage pipeline, in which a transmitted sound wave signal (S, S′) is fed at a predetermined feed point into the pipeline (1) and propagates in an axial direction of the pipeline (1), wherein the frequency spectrum of the transmitted sound wave signal (S, S′) has a frequency component or a spectral range with a maximum frequency that is smaller than the lower limit frequency (fc) for the first upper mode, in which, within the pipeline (1), reflected portions (Sr1, Sr2, Sr3, S′r1, S′r2, S′r3) of the transmitted sound wave signal (S, S′) are detected as received sound wave signal (E, E′), and in which the pipeline (1) is examined by an evaluation of the received sound wave signal (E, E′) with regard to the transmitted sound wave signal (S, S′) as to the presence of reflection sites causing sound wave reflections (Sr1, Sr2, Sr3, S′r1, S′r2, S′r3) along the pipeline (1), wherein, by means of the evaluation of the received sound wave signal (E, E′), in each case at least the distance (I) of a reflection site from the feed point is determined. The invention further relates to an apparatus for implementing the method.

Abstract:
A method for determining properties of a pipeline includes feeding a sound wave signal at a predetermined feed point into the pipeline so that the sound wave signal propagates in an axial direction of the pipeline. The frequency spectrum of the transmitted sound wave signal has a frequency component or a spectral range with a maximum frequency that is smaller than the lower limit frequency for the first upper mode. Reflected portions of the transmitted sound wave signal are detected as received sound wave signal and are evaluated with regard to the transmitted sound wave signal to determine at least the distance of each reflection site from the feed point.
Abstract:
The present disclosure relates to control units for an extracorporeal circulatory support as well as systems comprising such a control unit and corresponding methods. Accordingly, a control unit for an extracorporeal circulatory support is suggested, which is configured to receive a measurement of an ECG signal of a supported patient over a predefined period of time, wherein the ECG signal comprises multiple data points for each time point within a cardiac cycle. The control unit comprises an evaluation unit, which is configured to evaluate the data points for at least one time point spatially and/or temporally and to determine at least one amplitude change within the cardiac cycle from the evaluated data points. The control unit is further configured to output a control signal for an extracorporeal circulatory support at a predefined time point after the at least one amplitude change.
