  • Publication number: 20240006332
    Abstract: An integrated circuit (IC) device comprises a host component and an IC die directly bonded to the host component. The IC die comprises a substrate material layer and a die metallization level between the substrate material layer and host component. The IC die includes an upper die alignment fiducial between the die metallization level and host component. The upper die alignment fiducial at least partially overlaps one or more metallization features within the die metallization level. In embodiments, at least two orthogonal edges of the upper die alignment fiducial do not overlap any of the metallization features within the die metallization level. In embodiments, the IC die includes a lower die alignment fiducial between the substrate material layer and the die metallization level. The lower die alignment fiducial may at least partially overlap one or more second metallization features within a second die metallization level of the IC die.

  • Patent number: 9026347
    Abstract: An expert system manages a power grid wherein charging stations are connected to the power grid, with electric vehicles connected to the charging stations, whereby the expert system selectively backfills power from connected electric vehicles to the power grid through a grid tie inverter (if present) within the charging stations. In more traditional usage, the expert system allows for electric vehicle charging, coupled with user preferences as to charge time, charge cost, and charging station capabilities, without exceeding the power grid capacity at any point. A robust yet accurate state of charge (SOC) calculation method is also presented, whereby initially an open circuit voltage (OCV) based on sampled battery voltages and currents is calculated, and then the SOC is obtained based on a mapping between a previously measured reference OCV (ROCV) and SOC. The OCV-SOC calculation method accommodates likely any battery type with any current profile.
