  • Publication number: 20240176141
    Abstract: An optical combiner includes first, second, and third polarization volume holograms (PVHs) configured to deflect light of a first color, a second color, and a third color, respectively. The optical combiner further includes a first polarization interference filter (PIF) configured to switch light of the first color from a polarization that is not deflected by the first PVH to a polarization that is deflected by the first PVH. The optical combiner may further include a second PIF configured to switch light of the second color from a polarization that is not deflected by the second PVH to a polarization that is deflected by the second PVH. The optical combiner may further include a third PIF configured to switch light of the third color from a polarization that is not deflected by the third PVH to a polarization that is deflected by the third PVH.

  • Patent number: 11968597
    Abstract: A method for calculating a time-of-arrival of a multicarrier uplink signal includes: accessing a multicarrier reference signal including a subcarrier reference signal for each subcarrier frequency in a set of subcarrier frequencies; receiving the multicarrier uplink signal transmitted from a user device, the multicarrier uplink signal including a subcarrier uplink signal for each subcarrier frequency in the set of subcarrier frequencies; for each subcarrier frequency in the set of subcarrier frequencies, calculating a phase difference, in a set of phase differences, between the subcarrier reference signal for the subcarrier frequency and a subcarrier uplink signal for the subcarrier frequency; calculating a time-of-arrival of the multicarrier uplink signal at the transceiver based on the set of adjusted phase differences; and transmitting the time-of-arrival of the multicarrier uplink signal to a remote server.

  • Publication number: 20240097811
    Abstract: A method including accessing a network graph including: a set of transceiver nodes representing a set of transceivers operating in a mesh network of transceivers; a set of transmitter nodes representing a set of transmitters communicating with the mesh network of transceivers; and a set of edges, each connecting a pair of nodes in the set of nodes. The method also includes: identifying a subgraph of the network graph associated with a node in the set of nodes, the node representing a transceiver; accessing a network state of the subgraph comprising a set of edge values for each edge in the subgraph; calculating a probability of failure of the transceiver based on the network state of the subgraph; and in response to detecting the probability of failure of the transceiver exceeding a threshold likelihood, triggering a corrective action at the transceiver.

  • Patent number: 11782476
    Abstract: A memory controller conveys a clock signal with command and address signals to a registered clock driver (RCD) on a memory module. A controller-side chip interface on the RCD supports both source-synchronous and filtered clocking for receipt of the command and address signals, the selection between the two clocking schemes dependent upon the noise environment impacting the clock and command/address signals. If the noise is predominantly correlated, then the chip interface is placed in a source-synchronous clocking mode. If the noise is predominantly uncorrelated, then the chip interface is placed in a filtered clocking mode that filters out uncorrelated noise from the clock signal.

  • Publication number: 20140325432
    Abstract: Described herein are embodiments performed by a computing device capable of having a first display and a second display. The device may also execute a windowing system. Arbitrary applications execute on the computing device. Each such application has a corresponding application window managed by the windowing system. A start-projecting request may be received from an arbitrary one of the applications, and the windowing system may respond to the start request by generating, displaying, and managing a projection window. The application may generate and display content via the projection window. Responsive to the start-projecting request, display information about the first display and the second display may be used by the windowing system to display the projection window. A stop-projecting request from the application may cause the windowing system to terminate the projection window.
