  • Publication number: 20240130359
    Abstract: Described herein are quaternary ammonium polymers and interpenetrating polymer networks and compositions thereof with broad spectrum antimicrobial properties that produce fast acting, long lasting, non-toxic and non-allergenic colorless and transparent durable surface coatings that are resistant to water and common solvents. The surface coatings are easy and cost effective to produce from readily-available materials using versatile synthesis enabling a wide range of chemical variations. They are readily applied to a wide range of surfaces and materials, and no materials leach out of the coatings.

  • Publication number: 20240134121
    Abstract: A system of aligning concatenated sections of multicore optical fiber incorporates the capability of intentionally changing core assignments as part of the azimuthal alignment process. The intentional changing of core assignments, referred to as offset clocking, compensates for differences in properties of the individual core regions in a way that reduces variations between the spatial channels supported in the transmission system. The offset clocking technique can be used, e.g., to improve the attenuation (or other selected properties of the propagating signals). The offset clocking technique may be used to step through sequential changes core assignments at one or more splice locations (passive clocking) or identify a particular pairing of cores from one fiber section to the next (e.g., “good quality” core assigned to a “poor quality” signal exiting the first section) and rotate the fiber sections with respect to each other to achieve this particular core assignment.

  • Publication number: 20240129730
    Abstract: A user equipment (UE) configured to connect to an edge data network. The UE connects to a first edge application server (EAS) of an edge data network (EDN), the connecting comprising performing a first authorization/authentication procedure, receives a message indicating the UE is to connect to a second EAS of the EDN, the message including an indication as to whether the UE is to perform a second authorization/authentication procedure to connect to the second EAS and performs a discovery procedure to locate the second EAS based on at least the indication in the message.

  • Patent number: 11955472
    Abstract: Disclosed are embodiments of a semiconductor structure that includes a semiconductor-controlled rectifier (e.g., for electrostatic discharge (ESD) protection). The SCR can be readily integrated into advanced semiconductor-on-insulator processing technology platforms (e.g., a fully depleted silicon-on-insulator (FDSOI) processing technology platform) that employ hybrid semiconductor substrates (i.e., semiconductor substrates with both bulk semiconductor and semiconductor-on-insulator regions) and is configured with an on-Pwell semiconductor-on-insulator gate structure that is tied to an anode terminal to effectively lower the SCR trigger voltage. To further lower the trigger voltage of the SCR, the Pwell on which the gate structure sits may be made narrower than the gate structure and/or the doping profile of the Pwell on which the gate structure sits may be graded (e.g., P to P? closer to insulator layer).

  • Publication number: 20240070794
    Abstract: A document management system uses machine learning to identify legal obligations within contract documents. The document management system trains a machine-learned model using historical contract documents having historical legal obligations; the trained machine-learned model is configured to identify portions of text within a contract document that correspond to legal obligations. The machine-learned model, applied to a set of contract documents, identifies a set of legal obligations. The document management system presents, via a user interface, information about the set of identified legal obligations.

  • Publication number: 20230262913
    Abstract: Housings for electronic devices may include a steel body, such as a stainless steel body, that has an outer portion and an inner portion. The outer portion may exhibit an average Vickers hardness of 200 HV or higher. The inner portion may exhibit an average Vickers hardness of 180 HV or lower. The lower hardness of the inner portion may facilitate working the material of the inner portion, such as to form attachment points, protrusions, holes, or other features. Various additional devices, methods, and systems are also disclosed.

  • Publication number: 20230223986
    Abstract: A radio communications device includes a RTC configured to run even during sleep for receiving from a coordinator node (CN) in an asynchronous channel hopping WPAN an asynchronous hopping sequence (AHS) frame that includes the CN's hopping sequence. A processor implements a stored sleepy device operation in asynchronous channel hopping networks algorithm. The algorithm is for determining a time stamp for the AHS frame and the CN's initial timing position within the hopping sequence, storing the time stamp, going to sleep and upon waking up changing a frequency band of its receive (Rx) channel to an updated fixed channel. A data request command frame is transmitted by the device on the CN's listening channel that is calculated from the CN's hopping sequence, time stamp, CN's initial timing position and current time, and the device receives an ACK frame transmitted by the CN at the updated fixed channel of Rx operation.

  • Patent number: 9819393
    Abstract: In a disclosed embodiment, a power line communication (PLC) device sends an active channel scan request from a host layer to an adaptation layer. In response to the adaptation layer receiving the request, a MAC layer is instructed to broadcast a beacon request frame. The PLC device receives from each of one or more neighboring devices that respond to the beacon request frame a beacon frame including an address and a personal area network (PAN) identifier. A listing of PAN identifiers indicated by the beacon frames is provided to the host layer. The host layer selects a target network corresponding to a selected PAN identifier and selects one of the one or more neighboring devices associated with the selected PAN identifier as a target bootstrapping agent. The host layer instructs the adaptation layer to join the target network using the target bootstrapping agent.
