  • Monitoring and mitigation of row disturbance in memory
    Patent number: 11527280
    Abstract: A memory device comprises a memory array, a counter unit, and a service unit. The memory array comprises cells arranged in rows and columns, wherein a subset of the cells in each of the rows holds a row activation count for each row. The counter unit, in response to an activation of the row caused by a read operation on at least a portion of the row, increments the row activation count for at least one of the rows prior to a completion of the read operation, and writes-back the row activation count in an incremented state to the subset of the cells in the row that held the row activation count prior to the activation. The service unit is coupled to the counter unit and performs a service with respect to one or more other rows, offset from the row, in response to the row activation count associated with the row satisfying service criteria.

  • SINGLE USE CAPS AND COVERS FOR VASCULAR ACCESS DEVICES, AND KITS AND METHODS FOR USING THE SAME
    Publication number: 20220370782
    Abstract: This invention concerns improved single use caps or covers for vascular access devices such as needlefree connectors that are used, for example, in intravenous administration sets and extension sets. Removal of a single use cap or cover according to the invention from a vascular access device destroys the cap such that it cannot be reused. Such single use caps and covers will help ensure compliance with infection prevention protocols in healthcare settings, which will assist in reducing the incidence of healthcare-associated infections (HAIs), particularly catheter-related blood stream infections. Assemblies and kits its including such caps and covers, for example, IV administration and extension sets that include one or more needlefree connectors, as well as methods for using such caps and covers, are also described.

  • Evacuated gratings and methods of manufacturing
    Patent number: 11442222
    Abstract: Improvements to gratings for use in waveguides and methods of producing them are described herein. Deep surface relief gratings (SRGs) may offer many advantages over conventional SRGs and Bragg gratings, an important one being a higher S-diffraction efficiency. In one embodiment, deep SRGs can be implemented as polymer surface relief gratings or evacuated Bragg gratings (EBGs). EBGs can be formed by first recording a holographic polymer dispersed liquid crystal (HPDLC) grating. Removing the liquid crystal from the cured grating provides a polymer surface relief grating. Polymer surface relief gratings have many applications including for use in waveguide-based displays.
