  • Patent number: 10959697
    Abstract: Synchronizing operation between a digital radiographic detector's integration periods and an x-ray generator's x-ray pulse rate by transmitting a frame rate to the detector and the generator. In a first mode, the detector monitors one or more pixels to detect an x-ray pulse. The firing time of the detected x-ray pulse relative to an internal clock of the detector is used to synchronize the detector's integration periods with the pulse rate of the x-ray generator based on the transmitted frame rate and the detected firing time of the x-ray pulses. Successive pulses may also be used to determine a frame rate without prior transmission thereof.

  • Patent number: 10838834
    Abstract: A system and method for efficiently distributing data among multiple storage devices. A data storage array receives read and write requests from multiple client computers. The data storage array includes multiple storage devices, each with multiple allocation units (AUs). A storage controller within the data storage array determines a RAID layout for use in storing data. In response to determining a failure of a first AU, the storage controller begins reconstructing in a second AU the data stored in the first AU. For read and write requests targeting data in the first AU, the request is serviced by the first AU responsive to determining no error occurs when accessing the first AU.
