摘要:
A position transmitter for determining a position of a rotating shaft, has an AMR sensor unit or a GMR sensor unit which, for determining the position, has only one magnet disposed on a shaft to be monitored, whereby the position transmitter can be used as a single-turn and a multi-turn unit. Furthermore, a method for determining a position of a rotating shaft with the position transmitter is also provided. In accordance with the method, signals are produced using a diametrically magnetized magnet in a sensor unit, so that sine and cosine signals are obtained as output signals of the AMR sensor unit, the sine and cosine signals are digitalized, and these signals are processed by a microcontroller, with regard to the detection and evaluation of the angle of rotation, for detecting, filtering, and evaluating the number of revolutions, for detection of the direction of rotation or for data transmission of the angle of rotation and the number of revolutions to an overriding control.

The invention relates to a method for the diagnosing or for the confirmation or for the exclusion of constellations of risk factors, pathological states or predispositions thereto, and to a method for monitoring the course of therapies and for finding active substances for the treatment of pathological states and for finding substances which may cause such a pathological state, on the basis of lipid measurement parameter modulation/effector quotient profiles. Further, the invention relates to a measuring instrument for carrying out the above methods.

According to an exemplary embodiment of the present invention, an iterative reconstruction of coronary arteries comprises a filtering of projection data on the basis of a top-hat filter and an iterative reconstruction of the object of interest on the basis of a regularisation favouring sparse objects. This may provide for high contrast and detail.
摘要:
A monitoring device for a motor-driven door with a door controller for detecting a crash of a moving object with the door and for communicating information as to whether a crash has occurred to the door controller, wherein the monitoring device is equipped with at least one sensor for monitoring movement, shaking and/or vibration of the door in a Z axis, which sensor is disposed in and/or on the door leaf of the door, and wherein there is provided an analyzer unit, which is designed as an analyzer unit that analyzes the signals of the sensor and transmits an information stream to the door controller.

The invention relates to an X-ray detector (1) with an array (2) of sensor elements (21), wherein each row (i) of sensor elements is connected via an addressing line to an addressing unit (5), and wherein each column j) of sensor elements is connected via a read-out line to a read-out unit (3). In the read-out unit (3), sensor signals are preprocessed, for example amplified by amplifiers (31). The detector further comprises a control unit (6) which is adapted to set the gains of said amplifiers (31) for each column (j) and each row (i) individually. The values of the gains may particularly be derived from a priori knowledge, from previous images of the object, or from the image signals of rows that have already been read out.
摘要:
A monitoring method and a monitoring device for a motor-driven door, wherein a stationary unit and a monitoring device mounted on the movable door communicate bidirectionally with one another, wherein data and/or signals of at least one door safety sensor are relayed to the stationary unit, and wherein a waking device is automatically wakened cyclically or is wakened by a vibration sensor and wakes the control device, which in turn wakes the transmitter/receiver and actively queries the stationary unit assigned individually to it as to whether the monitoring device must remain active or be switched back to a power-saving idle state.
