    • Embodiments of the present invention are directed at identifying an idle state for a processor that minimizes power consumption. In accordance with one embodiment, a method for identifying a target idle state that does not require a linear progression into any intermediate states is provided. More specifically the method includes collecting data from a plurality of data sources that describes activities occurring on the computer and/or attributes of the hardware platform. Then, using the collected data, a target idle state for the processor is calculated. Finally, if the current idle state of the processor is different than the target idle state, the method causes the idle state of the processor to be changed to the target idle state.
    • 本发明的实施例涉及识别最小化功耗的处理器的空闲状态。 根据一个实施例,提供了一种用于识别不需要线性进展到任何中间状态的目标空闲状态的方法。 更具体地,该方法包括从描述在计算机上发生的活动和/或硬件平台的属性的多个数据源收集数据。 然后,使用收集的数据,计算处理器的目标空闲状态。 最后,如果处理器的当前空闲状态不同于目标空闲状态,则该方法使处理器的空闲状态改变为目标空闲状态。

    • Processor power management capabilities that enable an operating system kernel to interact with a plurality of ACPI-compliant computing devices to manage processor power using a generic processor description is described. Specifications of power processor management capabilities of processor types are stored in data structures, i.e., objects. Each object contains a control value field and a control mask field and may also contain a status value field and a status mask field. The kernel loads a generic processor driver and objects for each processor type enabling the kernel to respond to power management events such as, but are not limited to, processor utilization and processor operating temperature events. In response to a power management event, the kernel calculates a desired processor performance state; sets bits in the control mask field to describe the desired processor performance state; and passes the control mask to the generic processor driver which controls the processor. Responses to power management events include, but are not limited to, adjusting processor voltage and/or adjusting processor frequency.

    • A device configuration silo is arranged to be accessed as an IEEE 1667-compatible silo which exposes interfaces to a host application to make changes to the presence of one or more other silos, as well as make changes to silo configurations on a per-silo basis for data and method sharing among silos across the ACTs on a storage device such as a transient storage device. The interfaces exposed by the device configuration silo are arranged to enable an authenticated provisioner, like administrator in a corporate network environment, to perform configuration changes to silos after the storage device is released into the field through a secure provisioning mechanism. In addition, users may make configuration changes to silos at runtime in some usage scenarios, for example to enable discrete portions of functionality on a storage device, by using a secure secondary authentication mechanism that is exposed by the device configuration silo.

    • An evaporative emissions control system for small internal combustion engines. The system generally includes a charcoal canister and a carburetor with a fuel circuit shutoff valve. The charcoal canister is in fluid communication with the air space above the liquid fuel within the engine fuel tank, and optionally, with the air space above the liquid fuel within the fuel bowl of a fuel bowl-type carburetor. The charcoal canister contains charcoal media which absorbs fuel vapors when the engine is not running. During running of the engine, vacuum within the carburetor induces a flow of atmospheric air through the charcoal canister to purge the collected fuel vapors from the charcoal media, and the fuel vapors pass into the engine for consumption. The carburetor of the engine, which may be either a fuel bowl-type carburetor or a diaphragm carburetor, includes a fuel circuit shutoff valve controlled either by a vacuum signal produced within the engine or by a user-actuated mechanical linkage. The fuel circuit shutoff valve closes the fuel circuit of the carburetor upon engine shutdown to prevent escape of fuel vapors from the carburetor to the atmosphere. In another embodiment, a weir-type carburetor is disclosed which contains a minimal amount of fuel when the engine is not running to reduce or eliminate evaporative emissions.
