  • Publication number: 20230319676
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify an aggregation capability to communicate in parallel over a plurality of wireless links. The wireless device may in some cases broadcast this aggregation capability (e.g., periodically). Additionally or alternatively, the wireless device may transmit the aggregation capability in response to a request received from another wireless device. In some cases, the first wireless device may transmit a request to a second wireless device inquiring about aggregation capabilities of the second wireless device. The second wireless device may respond with its aggregation capabilities (e.g., or may broadcast its aggregation capabilities independently of receiving the response). The wireless devices may establish a multi-link session based at least in part on the indicated aggregation capabilities.

  • Patent number: 11747181
    Abstract: A method of calculating a time difference is disclosed. The method includes sampling a first ultrasonic signal (r21) to produce a first sampled signal (y1(i)) and sampling a second ultrasonic signal (r12) to produce a second sampled signal (y2(i)). A first time (LEAD_LAG) is determined between a time the first sampled signal crosses a threshold (?1) and a time the second sampled signal crosses the threshold. The first sampled signal is cross correlated with the second sampled signal to produce a second time (SAMP_OFFSET). The time difference is calculated in response to the first and second times.

    Abstract: The disclosure herein describes tracking changes to a stale component using a synchronization bitmap. A first component of a plurality of mirrored components of the distributed data object becomes available from an unavailable state, and a stale log sequence number (LSN) and a last committed LSN are identified. A synchronization bitmap of the first component associated with a range of LSNs (e.g., from the stale LSN to the last committed LSN) is created and configured to track changes to data blocks of the first component. A second component is identified based on the second component including a tracking bitmap associated with an LSN that matches the stale LSN of the first component. The first component is synchronized with data from the second component based on, wherein the synchronizing includes updating the synchronization bitmap to track changes made to data blocks of the first component.

  • Patent number: 11588471
    Abstract: Examples of amplifiers and nth-order loop filters thereof are configured to enable fast and robust recovery from saturation, while limiting signal distortion at or near full power delivery across multiple process and temperature corners. An example nth-order loop filter comprises n series-coupled resistor-capacitor (RC) integrators. In an example, each of the second RC integrator to the (n?1)th RC integrator has a reset mechanism responsive to a reset signal output from a reset controller when an input signal overload condition is detected at the input. Upon detecting the overload condition, each of the third RC integrator to the (n?1)th RC integrator is hard reset, the nth RC integrator is not reset, and a controlled reset is performed on the second RC integrator to recover from saturation caused by the signal overload condition, while maintaining the output signal below the 1% total harmonic distortion (THD) level at or near full power delivery.
