  • Patent number: 9330222
    Abstract: Disclosed are methods, systems, and articles of manufacture for implementing electronic circuit designs with electro-migration awareness. Some embodiments perform schematic level simulation(s) to determine electrical characteristics, identifies physical parasitics of a layout component, determines the electrical or physical characteristics associated to electro-migration analysis on the component, and determines whether the component meets EM related constraint(s) while implementing the physical design of the electronic circuit in some embodiments. Some embodiments further determine adjustment(s) to the component or related data where the EM related constraints are not met and/or and present the adjustment(s) in the form of hints. Various data and information, such as currents in various forms or voltages, are passed between various schematic level tools and physical level tools.

  • Patent number: 9249551
    Abstract: A clamp assembly for a pile driving system for driving a concrete sheet pile, the clamp assembly comprising a clamp body, a first clamp member supported relative to the clamp body, and a second clamp member supported for movement relative to the clamp body, and a bumper member. A clamp region is formed between the first and second clamp members. The bumper member is supported relative to the clamp body above the clamp region. The clamp body is configured such that the concrete sheet pile enters the clamp region from below. The second clamp member is displaced towards the first clamp member to engage the concrete sheet pile in the clamp region. The bumper member resiliently deforms to inhibit direct transmission of forces between the concrete sheet pile and the clamp body during driving of the concrete sheet pile.

  • Patent number: 9223925
    Abstract: Disclosed are methods, systems, and articles of manufacture for implementing electronic designs with simulation awareness. A schematic is identified or created and simulated at the schematic level to characterize the functional behavior of the circuit or to ensure the circuit design meets the required design specifications. Physical data of a component of the design is identified, created, or updated, and the electrical parasitic associated with physical data is characterized. One or more electrical characteristics associated with the parasitic is further characterized and mapped to the simulator to re-simulate the circuit design to analyze the impact of parasitics. Some embodiments re-run the same simulation process incrementally in an interactive manner by accepting incremental design or parameter changes from the design environment.

  • Patent number: 9190855
    Abstract: A battery pack system module may include a module bypass switch for allowing charge current to bypass the battery pack system module. The module bypass switch may be activated to divert charging current from the battery pack system module to other battery pack system modules. The charging current may be diverted to bring other battery pack system modules into balance with the battery pack system module. That is, to bring the state of charge of all battery pack system modules into coarse balance. When the module bypass switch is activated, charging current through the module bypass switch may be monitored by a current sensing device such as a current sensing resistor. A microprocessor may receive information about the bypass current level and use the information to determine when to de-activate the module bypass switch. Sensing current through a module bypass switch allows more accurate and quicker inter-module balancing.

  • Patent number: 9099871
    Abstract: A battery pack system module may include a module bypass switch for allowing charge current to bypass the battery pack system module. A charge switch and a discharge switch may be coupled with the module bypass switch. When other battery pack system modules are coupled in series with the module, balancing between modules may be achieved by allowing charge current to bypass the unbalanced modules and charge other modules. For example, when an unbalanced module is at a higher level of charge than other modules, a charge switch and a discharge switch in the unbalanced module de-activate and a module bypass switch activates to allow charge current to rapidly bring other modules into balance. The discharge switch and the charge switch allow the charging current to bypass the unbalanced module creating little or no additional heat dissipation.

  • Patent number: 9097774
    Abstract: Internal shorts and other failures in lithium-ion battery cells may be detected during balancing of the battery cells. A counter may be used to detect when a battery cell is behaving differently than other battery cells by balancing more or less frequently. The counter may increment each time a battery cell is balanced to the other battery cells. A misbehaving battery cell may be flagged, when the counter exceeds a threshold value, for safety checks before an overheating event occurs. This misbehaving battery cell may be faulty due to an internal short. If the faulty battery cell is not corrected by replacement with a different battery cell or corrected by a user resetting the counter, the misbehaving battery cell may be disconnected to prevent the overheating event.
