  • Patent number: 12358755
    Abstract: Various embodiments are directed to a radar reflector configured for radar-based distance measurements for determining a position of an elevator car within an elevator shaft. The radar reflector comprises three or more triangular panels defining a pyramidal frustum volume having a base plane and an upper plane that are parallel. The pyramidal frustum volume is configured to directly reflect radar signals originating from a radar transceiver back to the radar transceiver based at least in part on the triangular panels being mutually perpendicular at a projected apex above the upper plane. The reflected radar signals reflected by the radar reflector have substantially parallel trajectories with the original, pre-reflected radar signals emitted by the radar transceiver. The triangular panels of the radar reflector being mutually perpendicular advantageously maintains direct reflection of radar signals in spite of any potential horizontal tilt of the radar reflector to a certain extent.

    Abstract: A heterogeneous computing system performs data synchronization. The heterogeneous computing system includes a system memory, a cluster, and a processing unit outside the cluster. The cluster includes a sync circuit, inner processors, and a snoop filter. The sync circuit is operative to receive a sync command indicating a sync address range. The sync command is issued by one of the processing unit and the inner processors. The sync circuit further determines whether addresses recorded in the snoop filter fall within the sync address range. In response to a determination that a recorded address falls within the sync address range, the sync circuit notifies a target one of the inner processors that owns a cache line having the recorded address to take a sync action on the cache line.
