The rectifier, coupled to the transformer, receives the amplified audio signal and rectifies the amplified audio signal to generate a rectified voltage signal. The power supply circuit is controlled by the rectified voltage signal to provide a supply voltage. The sensor is powered by the supply voltage to perform a sensing operation. An output signal which carries information related the sensing operation is generated.

  • Patent number: 9423511
    Abstract: When designing detector arrays for diagnostic imaging devices, such as PET or SPECT devices, a virtual detector, or pixel, combines scintillator crystals (10, 20, 40) with photodetectors (12) in ratios that deviate from the conventional 1:1 ratio. For instance, multiple photodetectors can be glued to a single crystal to create a virtual pixel (10, 20, 40) which can be software-based or hardware-based. Light energy and time stamp information for a gamma ray hit on the crystal can be calculated using a virtualizer processor or using a trigger line network and time-to-digital converter logic. Additionally or alternatively, multiple crystals (54) can be associated with each of a plurality of photodetectors (52). A gamma ray hit on a specific crystal is then determined by a table lookup of adjacent photodetectors (52) that register equal light intensities, and the crystal (54) common to such photodetectors (52) is identified as the location of the hit.

  • Patent number: 9423514
    Abstract: Detection apparatus for detecting radiation The invention relates to a detection apparatus for detecting radiation. The detection apparatus comprises at least two scintillators (14, 15) having different temporal behaviors, each generating scintillation light upon reception of radiation, wherein the generated scintillation light is commonly detected by a scintillation light detection unit (16), thereby generating a common light detection signal. A detection values determining unit determines first detection values by applying a first determination process and second detection values by applying a second determination process, which is different to the first determination process, on the detection signal. The first determination process includes frequency filtering the detection signal.

  • Patent number: 9417334
    Abstract: Preprocessing is conducted on a unipolar pulse output from a photomultiplier tube, to thereby generate a bipolar signal (bipolar pulse). In the bipolar signal, the falling waveform portion (back slope) of the initial peak waveform is steep, and also cuts across the baseline, whereby it is possible to accurately identify the falling point as the zero crossing point. The accuracy of identification of the pulse width “t” can be improved thereby. In addition to the pulse width, further reference may be made to the crest value of the unipolar pulse, the crest value of the bipolar signal, and the like, when determining line type.

    Abstract: The invention relates to a method for determining a distance between charged particle beamlets in a multi-beamlet exposure apparatus. The apparatus is provided with a sensor comprising a converter element for converting charged particle energy into light and a light sensitive detector provided with a two-dimensional pattern of beamlet blocking and non-blocking regions. The method comprises scanning a first beamlet over the pattern, receiving light generated by the converter element, and converting the received light into a first signal. Then the two-dimensional pattern and the first beamlet are moved relatively with respect to each other over a predetermined distance. Subsequently, the method comprises scanning a second beamlet over the pattern, receiving light generated by the converter element, and converting the received light into a second signal. Finally, the distance between the first beamlet and second beamlet is determined based on the first signal, the second signal and the predetermined distance.
