  • Publication number: 20230195200
    Abstract: Embodiments herein relate to optimizing the operation of multiple integrated circuits (ICs) operating in parallel. In one aspect, the ICs are arranged in a voltage-stacked configuration, and an operating frequency of each IC is controlled using a tunable replica circuit to stabilize its voltage drop. The tunable replica circuit mimics a critical path on the IC. In another aspect, an IC is divided into top and bottom portions which are in respective voltage domains on a substrate. The substrate include a deep n-well region for the higher voltage domain. In another aspect, a physically unclonable function (PUF) is used to generate identifiers for each IC among a multiple ICs on a board. Entropy sources of the PUF generate bits of the identifiers. Unstable entropy sources are identified and their bits are masked out.

  • Publication number: 20220223330
    Abstract: Technologies for an inductor with a meandering conductor are disclosed. In the illustrative embodiment, an inductor has a conductor that follows a meandering U-shaped path. The two nearby conductive strips carrying current in opposite directions largely cancel their magnetic fields, leading to less field on nearby traces on a circuit board. As a result, high-speed traces on the circuit board can be routed near the inductor, resulting in a potentially smaller form factor for the circuit board or a circuit board with few layers.

  • Patent number: 11219086
    Abstract: Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

  • Patent number: 11140641
    Abstract: Aspects directed towards synchronizing out of coverage (OOC) vehicle-to-everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.

  • Patent number: 11039458
    Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to determine a schedule for transmissions on subchannels of multiple frequencies based on a set of UE-specific, dynamic, and performance related metrics or criteria. The metrics may include an estimated number of users on a subchannel, a best-bandwidth fit, channel loading conditions, transmission range, and quality requirements of an application, among others. Such a schedule for transmissions on subchannels of multiple frequencies may result in either an improved capacity utilization, an improved communication quality, or both.

  • Patent number: 11026641
    Abstract: Systems and methods are provided for classifying a tissue mass as malignant or benign. The method includes identifying a region of interest in the tissue mass in computed tomography (CT) imaging data, segmenting the CT imaging data to delimit at least a portion of the tissue mass into image segments, extracting a set of radiomic parameters indicative of the tissue mass. The set of radiomic parameters may include tissue mass location, tissue mass shape, tissue mass surface characteristic, or tissue mass texture distribution indicative of the amount of image segments identified. The method also includes generating a report classifying the indeterminate lung nodule as being malignant or benign based on the set of radiomic parameters of the indeterminate lung nodule.
