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.

Apparatus for reducing accesses to levels of a storage hierarchy in a computing system

A computer tablet includes a wireless receiver, and a pen is configured to be manipulated by a person to ride against the computer tablet and thereby provide input to the computer tablet. The pen includes a wireless transmitter. A processor associated with the computer tablet outputs an alarm when a signal from the transmitter of the pen is not sensed by the computer tablet within a time period.

A fansink arrangement for a laptop computer wherein two distinct patterns of air intake can be employed. Particularly, dual air intakes of the laptop can be managed and controlled depending upon an operating mode of the computer. Thus, when the computer is in a 'stand alone' mode, only one air intake is employed while in a 'docking' mode of the computer two air intakes are employed.

Low-profile, compact embedded multi-mode 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 0.8 GHz to about 11 GHz.

Embedded multi-mode antenna architectures for wireless devices

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.

Computer and method for on-demand network access control

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.

Low-profile embedded antenna architectures for wireless devices

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.
