  • Patent number: 9343824
    Abstract: The present disclosure describes a conductive fastener assembly, system, and method, wherein the fastener assembly comprises a nut having a counterbore formed therein. The counterbore is formed to maintain a sufficient gap between the nut and the protruding end of a fastener sleeve. The nut with the counterbore improves the conductive fastener system such that the need for a solid copper grid and a cap seal is reduced or eliminated.

  • Patent number: 9331402
    Abstract: The present disclosure describes a conductive fastener assembly, system, and method, wherein the fastener assembly comprises a fastener, a fastener sleeve, a nut, and a lubricant coating. The lubricant coating is deposited on a distal portion of a fastener shank and is omitted from the rest of the fastener. To overcome the stresses placed on the fastener sleeve by the insertion of the fastener shank largely devoid of a lubricant coating, the fastener sleeve is reinforced by one or more of an increased thickness, a high-strength alloy, and a soft metal coating.

  • Publication number: 20150357030
    Abstract: Static random access memory (SRAM) circuits are used in most digital integrated circuits to store representations of data bits. To handle multiple concurrent memory requests, an efficient dual-port six transistor (6T) SRAM bit cell is proposed. The dual-port 6T SRAM cell uses independent word lines and bit lines such that the true/data side and the false/data-complement side of the SRAM bit cell may be accessed independently. Single-ended reads allow the two independent word lines and bit lines to handle two independent read operations in a single cycle using spatial domain multiplexing. Single-ended writes are enabled by adjusting the VDD power voltage supplied to a memory cell when writes are performed such that a single word line and bit line pair can be used write either a logical “0” or logical “1” into either side of the SRAM bit cell.

  • Publication number: 20150234950
    Abstract: Multi-port memory circuits are often required within modern digital integrated circuits to store data. Multi-port memory circuits allow multiple memory users to access the same memory cell simultaneously. Multi-port memory circuits are generally custom-designed in order to obtain the best performance or synthesized with logic synthesis tools for quick design. However, these two options for creating multi-port memory give integrated circuit designers a stark choice: invest a large amount of time and money to custom design an efficient multi-port memory system or allow logic synthesis tools to inefficiently create multi-port memory. An intermediate solution is disclosed that allows an efficient multi-port memory array to be created largely using standard circuit cell components and register transfer level hardware design language code.

  • Patent number: 8901180
    Abstract: The invention relates to a method for functionalizing a thermoset, crosslinked isocyanate-based polymeric solid material which is made of isocyanate and isocyanate reactive components, at least one of which comprises an anchor component which has at least one anchor group. The anchor groups on the solid material are formed by terminal alkene and/or alkyne groups. To functionalize this polymeric solid material it is brought in contact with a solution which contains at least one functional component. This functional component comprises at least one thiol group and is allowed to bind covalently to the polymeric solid material by a free-radical addition reaction between the thiol groups on the functional component and the terminal alkene and/or alkyne anchor groups on the undissolved solid material. An effective functionalization of the polymeric material can thus be achieved notwithstanding the heterogeneous reaction conditions.

The dual port 6T SRAM cell uses independent word lines and bit lines such that the true side and the false side of the SRAM cell may be accessed independently. Single-ended reads allow the two independent word lines and bit lines to handle two reads in a single cycle using spatial domain multiplexing. Writes can be handled faster that read operations such that two writes can be handled in a single cycle using time division multiplexing. To further improve the operation of the dual port 6T SRAM cell a number of algorithmic techniques are used to improve the operation of the memory system.
