  • Publication number: 20190252973
    Abstract: A control method and a switching device are provided for a separately excited synchronous machine as a drive in a hybrid or electric vehicle. The switching device converts and/or distributes electrical energy within the vehicle, in particular the hybrid or electric vehicle, wherein an asymmetric full bridge is provided, in the bridge branch of which a rotor of an SSM is arranged. Switches are provided in the asymmetric full bridge in order to provide a pulse width modulation corresponding to a desired motor rotational speed and power of the SSM. The device is characterized in that it has a short-circuit branch extending in parallel with the bridge branch of the asymmetric full bridge, by which short-circuit branch the rotor of the SSM is able to be short-circuited.

  • Publication number: 20190170880
    Abstract: The present invention relates to the correction of a detector signal d by superposing the detector signal with a correction signal. For providing a valid correction signal, a sampling pulse Ps is periodically or randomly provided. This sampling pulse serves as the initiator for sampling a process signal p of a process unit (14), which is configured to process the corrected detector signal. During the sampling of the process signal, the process signal is observed. In case a pulse at the process signal is detected, the sampling is assumed as not being suitable to correct the detector signal, since the pulse affects the process signal. Otherwise, namely in case such a process signal pulse does not occur during the sampling period, the process signal is further observed during a validation period, which is subsequently arranged to the sampling period.

  • Patent number: 10231678
    Abstract: A radiation detector (16) having a first detector layer (24) and a second detector layer (26) encircles an examination region (14). Detectors of the first layer include scintillators (72) and light detectors (74), such as avalanche photodiodes. The detectors of the second detector layer (26) include scintillators (62) and optical detectors (64). The scintillators (72) of the first layer have a smaller cross-section than the scintillators (62) of the second layers. A group, e.g., nine, of the first layer scintillators (72) overlay each second group scintillator (62). In a CT mode, detectors of the first layer detect transmission radiation to generate a CT image with a relatively high resolution and the detectors of the second layer detect PET or SPECT radiation to generate nuclear data for reconstruction into a lower resolution emission image. Because the detectors of the first and second layers are aligned, the transmission and emission images are inherently aligned.

  • Patent number: 10225696
    Abstract: Data transmission in a multicast fashion in which retransmissions are requested by recipients sending feedback to the one sender. Receiving stations are informed about the feedback of another receiving station. This is done by mirroring the feedback of receiving stations to other receiving stations. Due to this, in case, for example, one of the mirrored feedbacks is a negative acknowledgement message, the other receiving stations are informed that it is no longer necessary to provide their feedback, since a retransmission will be initiated anyway.

  • Patent number: 10078009
    Abstract: The invention relates to a method and a pulse processing circuit (100) for the processing of current pulses (CP) generated by incident photons (X) in a piece of converter material, for instance in a pixel (11) of a radiation detector. Deviations of the pulse shape from a reference are detected and used to identify pulse corruption due to pile-up effects at high count rates and/or charge sharing between neighboring pixels. The deviation detection may for instance be achieved by generating, with a pulse shaper (110), bipolar shaped pulses from the current pulse (CP) and/or two shaped pulses of different shapes which can be compared to each other.

  • Patent number: 9829377
    Abstract: The present invention relates to a detection device (6) for detecting photons emitted by a radiation source (2) and capable of adjusting ballistic deficit. The detection device (6) comprises a pre-amplifying unit (11) (such as, e.g., a charge-sensitive amplifier), a shaping unit (60) comprising a feedback discharge unit (13, I) (such as, e.g., a feedback resistor or a feedback current source), and a feedback discharge control unit (50) coupled to the feedback discharge unit (13, I). The feedback discharge control unit (50) is adapted to, e.g., adjust a resistance of a feedback resistor (and/or to adjust the current value of the feedback current source) if an electrical pulse generated by the shaping unit (60) does not exceed at least one energy comparison value (X1, X2, . . . , XN). The feedback discharge control unit (50) is adapted to not adjust the parameter of the feedback discharge unit (13, I) if the electrical pulse exceeds the at least one energy comparison value (X1, X2, . . . , XN).

  • Patent number: 9759822
    Abstract: The present invention relates to a detection device (6) for detecting photons emitted by a radiation source (2). The detection device (6) is configured to detect the photons during a first time period. The detection device (6) comprises a sensor (10) having an intermediate direct conversion material for converting photons into electrons and holes, a shaping element (20), and a compensation unit (450, INT, 950). The compensation unit (450, INT, 950) is adapted to provide a compensation signal based on the electrical pulse and on a photoconductive gain of said sensor (10). The core of the invention is to provide circuits to reduce artifacts due to inherent errors with direct conversion detectors in spectral computed tomography by determining a compensation current, by detecting or monitoring a baseline restorer feedback signal, or by ignoring signals above the baseline level.

  • Patent number: 9746566
    Abstract: The present invention relates to the correction of X-ray image information, e.g. the correction of X-ray image information regarding persistent currents in X-ray detector elements. X-ray detectors may be embodied as photoconductors with ohmic contacts, which output a photo current depending on the energy and amount of photons impinging on a respective photoconductor pixel. Such photoconductors may exhibit a photoconductive gain, i.e. the measured current when irradiated by X-ray is higher than the current, which would result from impinging photons only generating electron-hole pairs. To compensate for photoconductive gain a method (50) for image correction of X-ray image information is provided, comprising receiving (52) readout information of an X-ray detector element (14), wherein the readout information is dependent on impinging X-radiation (20) generating a photo current and compensating (54) the readout information for a photoconductive gain employing compensation information.
