摘要:
A computer and method that control access to a network. The computer includes an application that shrinks the window of opportunity for a network attack and reduces power consumption by automatically causing a computer to connect to the network when access is needed and to disconnect the computer from the network when access is not needed. The computer is automatically disconnected when it is deemed that network access is no longer needed, such as after a time period of no network activity. In turn, when the user, or the system, needs access to the network, the computer is automatically reconnected to the network. A software daemon on the computer may temporarily reconnect the computer to the network to access a server on the network to determine if attempts have been made to access the computer.

A power-aware monitor is provided for controlling the execution of state-unaware applications and optimizing their execution in light of power consumption issues. The power-aware monitor examines application usage to build profiles of resource consumption. When an application starts execution, the monitor determines the state of the battery to influence policy decisions. The monitor maintains a list of rules, which it uses in deciding policy. The user may modify these rules to override default behavior. The rules dictate whether an application executes unfettered, has its I/O, computation, or other activity restricted or delayed, or is completely aborted. When in doubt, the monitor may prompt the user for a decision.
摘要:
An information processing system comprises first and second levels of a storage hierarchy, wherein accessing information in the first level consumes more energy than accessing information in the second level; and a processor for writing information to the second level of storage based on energy-conserving criteria. The energy-conserving criteria comprise a set of heuristics, including system state information and user preferences.

A method (and system) of backing up and recovering data in a computer system includes incorporating a nonvolatile memory (NVM) into the computer system, backing up data from a storage of the computer system to said NVM, at a first time interval, and backing up data from the NVM to another storage at a second time interval.

An integrated circuit assembly includes an integrated circuit overlying a printed circuit board and a thermal solution interface such as a fan sink or a heat pipe overlying the integrated circuit. The lower surface of the thermal solution interface has a plurality of spacer structures to enforce a uniform displacement between the lower surface and an underlying surface contacted by the spacers. A heat transfer material, such as a thermal phase change material or a thermal grease, is positioned between the thermal solution interface and the underlying surface contacted by the spacers. The assembly may include a socket connected to the printed circuit board into which the integrated circuit is inserted. The spacers likely enforce a uniform displacement in the range of approximately 0.001 to 0.005 inches. The spacers may be configured as a set of substantially hemispherical protrusions or a set of substantially parallel elongated ridge protrusions.

Low-profile, compact UWB embedded antenna designs are provided for use with computing devices, such as laptop computers, which enable ease of integration within computing devices with limited space, while providing suitable antenna characteristics (e.g., impedance matching and radiation efficiency) over an operating bandwidth of about 1 GHz to about 11 GHz.

Low-profile, compact embedded antenna designs are provided for use with computing devices, such as laptop computers, which enable ease of integration within computing devices with limited space, while providing suitable antenna characteristics (e.g., impedance matching and radiation efficiency) over a desired bandwidth of operation. Compact antenna designs with reduced antenna size (e.g., antenna height) and increased operational bandwidth (e.g., broadband impedance matching) are achieved using slotted ground plane designs and/or doubling antenna feeding schemes.
