Abstract: The invention relates to a disaggregation apparatus (1) for identifying an electrical consumer in an electrical network (2). An electrical signature providing unit (7) provides electrical signatures of the electrical consumers (4, 5, 6), and an electrical parameter determining unit (8) determines an overall electrical parameter of the electrical network (2). An identification unit (9) identifies an electrical consumer depending on the determined overall electrical parameter and a correlation of the electrical signatures. Since the identification unit identifies an electrical consumer depending on the determined overall electrical parameter and a correlation of the electrical signatures, the identification of an electrical consumer does not depend on the detection of an event only. This makes the identification more robust, especially less prone to errors caused by missed events, thereby improving the reliability of identifying an electrical consumer in the electrical network.

A motion estimator module (40) determines a motion transform which transforms the LORs into a common motion state. A reconstruction module (50) reconstructs the motion corrected LORs into a static image or dynamic images, a series of high temporal resolution, high spatial resolution images.

Abstract: The invention relates to a detection device (6) for detecting photons emitted by a radiation source (2). A signal generation unit (20) generates a detection signal indicative of the energy of a detected photon while photons strike the detection device (6), and a baseline signal, which is affected by photons that previously struck the detection device (6), while photons are prevented from striking the detection device (6). A baseline shift determination unit (40) determines a baseline shift of the detection signal depending on the baseline signal. An energy determination unit (30) determines the energy of a detected photon depending on the detection signal and the determined baseline shift. Since the baseline shift of the detection signal is determined from a baseline signal that is generated while photons are prevented from striking the detection device (6), the baseline shift can be determined with higher accuracy, resulting in an improved energy determination.
