  • Patent number: 11963097
    Abstract: Communications between an access point (AP) and a non-AP station (STA) are established in a plurality of frequency segments within a basic service set (BSS) bandwidth or on at least a first link and a second link. An extreme-high-throughput (EHT) subchannel selective transmission (SST) operation is performed between the AP and the non-AP STA in the plurality of frequency segments or on the first link and the second link. A trigger-enabled target wake time (TWT) session period (SP) for the EHT SST operation by either indicating one of the plurality of frequency segments as containing a resource unit (RU) allocation addressed to the non-AP STA or indicating one of the first link and the second link on which an operating frequency segment is located during the TWT SP.

  • Patent number: 11963100
    Abstract: Power management operations are performed by devices communicating using multiple bands simultaneously where a first wireless band can be used to send and receive power management control frames for use on a second wireless band of a wireless network. In this way, a device that is in a sleep or dose power management state on a first band can be instructed to enter an awake power management state on the first band based on a communication received over a second band that is currently active and receiving data. Embodiments of the present invention enable power to be conserved when a band is not currently being used, or when there is no more data available (buffered) for a specific band.

  • Patent number: 11943643
    Abstract: An access point (AP) and a station (STA) communicate with each other, with the AP indicating to the STA either or both of a preamble detection (PD) channel and a signaling (SIG) content channel and with the STA being initially monitoring a primary frequency segment of a plurality of frequency segments in an operating bandwidth of the AP. A downlink (DL) or triggered uplink (UL) communication is performed between the AP and the STA during a transmission opportunity (TXOP) such that: (i) during the TXOP, the STA monitors a preamble on the PD channel and decodes a SIG content on the SIG content channel; and (ii) after an end of the TXOP, the STA switches to the primary frequency segment.

  • Patent number: 11943012
    Abstract: Embodiments of the present invention provide an apparatus and method for a MAP wireless network that includes a collaborative channel sounding measurement phase to determine channel state information between devices (e.g., the channel state between an STA and a collaborative AP) for efficient configuration of the MAP wireless network and to improve the performance of the MAP wireless networks. The wireless AP and wireless STAs associated with the collaborative APs can simultaneously transmit by applying collaborative beamforming where the interferences between channels nullify each other (e.g., nulling), and the beamforming is performed based on a sounding phase performed by the collaborative APs.

  • Publication number: 20240070167
    Abstract: An example operation may include one or more of receiving a message from an agent installed at a data replication server, the message comprising a status identifier of a checksum validation of a data replication operation, identifying a latency value associated with the data replication server, determining whether a data loss has occurred based on the status identifier of the checksum validation and the latency value, and in response to a determination that the data loss has occurred, transmitting a notification of the data loss to a computing system associated with the data replication server.

  • Patent number: 11917551
    Abstract: Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.

  • Patent number: 10987155
    Abstract: Bipolar forceps of the type where each of the prongs has a manually engageable portion spaced from the tip for manual squeezing of the prongs and an electrical supply system for applying a high-frequency electric current between tool tips to dissect through tissue planes and/or seal blood vessels includes a set of force measuring sensors for measuring forces, particularly squeezing forces, applied to the prongs at the tip. A temperature sensor is included to provide temperature information and temperature compensation. The sensors are applied to each prong in opposing pairs on the inside and outside surfaces and the outputs thereof are applied to a bridge arrangement. The signals are sent to a processor for generating warning signals and for recording forces for training purposes where a haptic system can be used.
