  • Publication number: 20120086400
    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: 8136901
    Abstract: In the case of printing at high addressability, where the cell size is smaller than the spot size, an image can be decimated in a manner that will limit the large accumulation of printed material. The proper decimation of the image will depend on the spot size, the physics of drop coalescence and the addressability during printing. A simple method of using concentric decimation is disclosed herein to enable this process.

  • Patent number: 8130986
    Abstract: Silicon and glass micromachined (MEMS) acoustic sensors incorporating trapped-liquid architectures are disclosed. The trapped liquid serves as an acoustic transmission medium allowing the input port to the system to be physically separated from the sensing location. The trapped liquid interacts with a conductive, flexible sensing membrane. Sound pressure waves enter the trapped liquid through an input membrane, travel to the sensing membrane, and excite vibrations of the sensing membrane. The vibrations of the sensing membrane are measured using on-chip capacitive sensing. The capacitive sensing structure is formed by the conductive sensing membrane and a fixed conducting top electrode. As the gap between the conductive sensing membrane and the fixed top electrode varies, the capacitance varies, leading to an electrical signal which is the electrical output of the system.

  • Publication number: 20120023465
    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.

    Abstract: Disclosed are a method, system, and computer program product for providing customizable information in designing electronic circuits with electrical awareness. The method or the system displays a portion of a physical design of an electronic circuit in a first display area. The method or the system receives or identifies a user's or a system's manipulation of the portion of the physical design of the electronic circuit. The method or the system then determines and displays an in situ response to the manipulation in the first display area. The method or the system may further display, in the first display area or in another display area, result(s) relating to the physical data of a component, electrical parasitic(s) associated with the physical data, electrical characteristic(s) associated with the physical data or the electrical characteristic(s), or other element(s) of the physical design that is impacted by the manipulation.

  • Publication number: 20120022846
    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.

  • Publication number: 20120023467
    Abstract: Disclosed are a method, system, and computer program product for implementing electronic circuit designs with electrical awareness. The method or the system updates the schematic level tool(s) and physical design tool(s) with electrical parasitic data or electrical characteristic data associated with electrical parasitics so both schematic and physical design tools are aware of the electrical parasitic or characteristic data in performing their functions such as extraction based simulations. The methods or systems are also aware of EM or IR-drop constraint(s) while implementing or creating a partial layout less than a complete layout. The method or the system also provides a user interface for a design tool to provide in situ, customizable, real-time information for implementing electronic circuit designs with electrical awareness. The methods or systems also support constraint verification for electronic circuit design implementation with electrical awareness.

  • Publication number: 20120023468
    Abstract: Disclosed are methods, systems, and articles of manufacture for constraint verification for implementing electronic circuit designs with electrical awareness. Some embodiments identify or set parasitic constraint(s) and compare the electrical parasitic(s) with corresponding parasitic constraint(s) to determine whether the parasitic constraints are met. Some embodiments first identify, determine, or update the physical data of a component of a partial layout and characterize the electrical parasitics associated with the physical data of the component. Some embodiments identify or determine some schematic level performance constraints and estimate parasitic constraints based on schematic simulation results and the performance constraints; the estimated parasitic constraints are then compared with the corresponding electrical parasitics to determine whether the constraints are satisfied.
