  • Publication number: 20200106929
    Abstract: A camera capable of quickly updating a region of interest (ROI) in its sensor array is provided. The camera is configured to image individual scan lines of a scan imager created as a scan beam is scanned across a subject. A different ROI is defined for each scan line to be imaged. To achieve this, a table of ROI-defining entries is loaded into the camera prior to imaging the scan lines. The ROI-defining entries are used to update the sensor's ROI during the camera's Frame-Overhead-Time. In this manner, the ROI is changed in between the imaging of consecutive scans lines.

  • Patent number: 9817734
    Abstract: Techniques for enabling virtual machine (VM) recovery on non-shared storage in a single virtual infrastructure management server (VIMS) instance are provided. In one set of embodiments, a VIMS instance can receive an indication that a VM in a first cluster of the VIMS instance has failed, and can determine whether the VM's files were being replicated to a storage component of the VIMS instance at the time of the VM's failure. If the VM's files were being replicated at the time of the failure, the VIMS instance can search for and identify a cluster of the VIMS instance and a host system within the cluster that (1) are compatible with the VM, and (2) have access to the storage component. The VIMS instance can then cause the VM to be restarted on the identified host system of the identified cluster.
