Publication number: 20240130359Abstract: 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.Type: ApplicationFiled: September 27, 2023Publication date: April 25, 2024Applicant: Polaroid IP B.V.Inventors: Stephen Robert Herchen, Rong-Chang Liang, Christian Ewald Janssen

Publication number: 20240134121Abstract: 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.Type: ApplicationFiled: July 10, 2023Publication date: April 25, 2024Applicant: OFS Fitel, LLCInventors: Tristan Kremp, Yue Liang, Robert L Lingle

Patent number: 11955472Abstract: 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).Type: GrantFiled: December 17, 2021Date of Patent: April 9, 2024Assignee: GlobalFoundries U.S. Inc.Inventors: Meng Miao, Alain Loiseau, Souvick Mitra, Wei Liang, Robert J.

Publication number: 20230223986Abstract: 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.Type: ApplicationFiled: March 17, 2023Publication date: July 13, 2023Inventors: KUMARAN VIJAYASANKAR, ROBERT LIANG, JYOTHSNA KUNDURU, KWANG SEOP EOM

Patent number: 9819393Abstract: 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.Type: GrantFiled: March 7, 2017Date of Patent: November 14, 2017Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Kumaran Vijayasankar, Ramanuja Vedantham, Robert Liang
