  • Publication number: 20240071038
    Abstract: A computing system implementing a physical verification tool can identify edges of a geometric pattern located within a search area surrounding a point of interest in a semiconductor layout design, characterize the edges of the geometric pattern based on locations of center points of the edges from the point of interest within the search area, and generate geometrical feature vectors for the point of interest in the semiconductor layout design based on the characterization of the edges of the geometric pattern. The computing system can reconstruct the semiconductor layout design corresponding to the search area surrounding the point of interest using the geometrical feature vectors for the point of interest in the semiconductor layout design.

  • Patent number: 11070065
    Abstract: A modular management system for balancing, testing and protecting rechargeable energy storage cells connected in series. Different energy storage cell technologies can be connected in the same battery pack and they can be completely balanced by using one or both of two balancing modes. In addition, the modular management system includes bidirectional and unidirectional switches optionally connected to a single ohmic device such as a resistor to efficiently execute a Dual Function Process (DFP) (i.e., passive/active balancing, and testing mode for SoH/SoC estimation) preferably without using any extra or external components (i.e., capacitor or inductor or DC/DC converter or power supply). The systems and methods decrease the balancing time, energy loss, heat loss and complexity needed to monitor, protect and balance energy storage cell systems such as battery systems, and thus decreasing the overall cost.
