  • Publication number: 20100195286
    Abstract: A heat sink assembly having excellent heat dissipation for internally integrated inverter hub motor for light electric vehicles and comprising of a thermally conducive ring, the electronic board consisting of multiple inverter switches, a potential secondary electronic board and a heat sink base, where the thermally conductive one piece ring is pressed down on the inverter switches to affix the switches to the hub of the motor thereby creating a mechanism for heat dissipation.

  • Publication number: 20100173188
    Abstract: The EMS modular battery pack is a convenient and maintainable battery pack that encompasses several modules that are fixed to a rigid structure that carries the battery management system and each module contains several cells which are connected in series via welded leads and are supported mechanically within each module. The division of module facilitates the removal of non-functional cells within the module with ease and the battery pack also provides a battery management system that detects a non functional module using the sensing circuitry built in each module. The modular battery pack design facilitates various configurations of battery pack both electrically and mechanically since any number of modules can be combined to build a battery pack.

  • Publication number: 20050034087
    Abstract: The present invention is directed to a method and apparatus for mapping platform-based design to multiple foundry processes. According to an exemplary aspect of the present invention, a method for mapping platform-based design to multiple foundry processes may include the following steps. First, availability of required features of a design in a target foundry process may be checked. The target foundry process must provide all the features that are used in the design. The design may include base wafer layers and metal stack layers. Then, a base wafer/metal stack interface layer for the design may be selected. Next, compatible blocks between different base wafer processes may be created. Then, a physical design library for the design may be created. Next, a logic design and timing library for the design may be created. This way, the design may be mapped to different foundry processes.

  • Patent number: 6667021
    Abstract: n the manufacture of sodium carbonate having increased CO2 uptakes the carbonation reaction to form sodium bicarbonate is enhanced by the addition of particular amounts of a cationic quaternary amine, selected from the family of dialkylethoxylated quaternary salts, benzylalkyl quaternary salts, or a combination of quaternary salts from these families, to treat the 25-30% by weight sodium carbonate liquor prior to filtration. The manufactured product yields a modified sodium carbonate liquor product that, when crystallized and converted to any anhydrous product, is more readily carbonated with CO2 in the production of sodium bicarbonate. The cationic additive reacts with organic materials in the sodium carbonate liquor to form solid polymeric by-products. Thus the treatment with a cationic compound is made prior to filtering the liquor. After filtering to remove the polymeric by-products and other solid materials, the liquor is evaporated or crystallized to produce a purified and modified sodium carbonate.

  • Patent number: 6270740
    Abstract: An improved method of purifying sodium carbonate from a natural source whereby a dissolved sodium carbonate product is treated with a cationic compound, such as a quaternary amine, to react with carbon-containing contaminants and filtering the product. The filtered modified sodium carbonate solution is then crystallized and dried. The modified sodium carbonate has a greater reactivity or uptake of carbon dioxide for the manufacture of sodium bicarbonate than conventional sodium carbonates.

  • Patent number: 5517658
    Abstract: A method for testing the timing parameters of a system design is presented, especially suited for use in testing for timing violations between the pins of a semiconductor device. A description of the timing constraints of the various modules of a design is written in a common non-technical vernacular, and functions as an input file. A Timing Shell Generator converts the input file description into a simulator-environment-compatible output code-language file description. The output code-language file is operative to implement the timing constraints of the original input file during simulation such that any violations of the prescribed timing constraints are indicated to the tester who can then take appropriate action.
