  • Patent number: 10236538
    Abstract: The battery management system can automatically re-combine batteries in a battery set in parallel connection or in series connection or in mixed series-parallel connection, or mixed parallel-series connection, and makes each individual cell in a battery being accessible, such that each individual cell can be monitored (i.e. its parameters can be measured) and charged or discharged. Therefore, with this system, batteries can be charged or discharged to their best performance.

  • Patent number: 9177627
    Abstract: This invention provides the method to overcome 4 backwards which limit the manufacturability or production yield rate of Magneto-resistive random access memory (MRAM). The key points of this invention are: (1) providing method to improve the manufacturability through reducing bias variation, by using a compensation module to correct the bias point of extreme cells; (2) providing method to improve the manufacturability through removing outlier cells (called bad cells), by using “writing jump-over” and “reading exclusion” to exclude bad-cells; (3) providing method to reduce the bias point, amplitude and asymmetry variation, using shared fixed-magnetic-reference-layer and proper shape anisotropy; (4) providing method to improve the write-ability, using flipping-assistant-field to speed up STT flipping process by large current, and using heating resistance and heating cells by the same current (including global heating, row heating, column heating, or local cell heating, i.e.

  • Publication number: 20140356656
    Abstract: This innovation is related to intelligent battery management system and method for optimizing the battery set to the best performance. The management system is supported by a cutting-edge method and corresponding embodiment, which can automatically re-combine batteries in a battery set in parallel connection or in series connection or in mixed series-parallel connection, or mixed parallel-series connection, and makes each individual cell in a battery being accessible, which means each individual cell can be monitored (i.e. its parameters can be measured) and charged or discharged. Therefore, with this system, batteries can be charged or discharged to their best performance.

  • Patent number: 7213985
    Abstract: New method for Image reproduction and recording is based on mechanical-guiding-apparatus-free operating methods, with flexible operations (hand, robot, vehicle), with the means for positioning, processing and controlling, and having exclusive plurality of uses. The system for image reproduction and recording based on this method includes these common apparatuses: head carrier, sprayer/reader or sprayer/reader array, and computer. Additional apparatuses used in wave-based positioning methods or relative-motion-based positioning methods, include operation-unit (OU) and communication-units (CU's), or operation-module (OM) and motion-detectors (MD), or respectively. The MD and OM provide the information of positioning for computer to determines the relative position and direction of the head array on head carrier. The CU's radiate and receive signal needed for determining distance information. The OU processes and converts the received signal into distance-related data and pass to computer.
