摘要:
Described is a system and method for transporting interference-related control data and other information between nodes in a wireless network, using a control channel that is distinct from a content channel used to transport content. The control channel may be a different channel in the same unlicensed band as the content channel, a channel in a different unlicensed band, or a channel in a licensed band, and thereby not subject to the same interference-related problems that the unlicensed content channel may experience. As a result, management information for adjusting the content channel's communication parameters may still be communicated between the nodes, whereby mitigation actions may occur. For example, the content channel may be changed to another frequency, compression may be implemented or varied, and/or the data transfer rate may be varied. The control data can also be used to change the control channel's communication parameters.

A system for binding a subscription-based computer to an internet service provider (ISP) may include a binding module and a security module residing on the computer. The binding module may identify and authenticate configuration data from peripheral devices that attempt to connect to the computer, encrypt any requests for data from the computer to the ISP, and decrypt responses from the ISP. If the binding module is able to authenticate the configuration data and the response to the request for data from the ISP, then the security module may allow the communication between the computer and the ISP. However, if either the configuration cycle or the response cannot be properly verified, then the security module may degrade operation of the computer.

Techniques are disclosed herein for allowing sharing of notes and ideas between electronic devices. The presence of a number of electronic devices is determined. A determination is made that the electronic devices are to be part of a shared workspace. A shared workspace is generated for the electronic devices. The shared workspace is displayed on a display screen of at least one of the electronic devices. The shared workspace that is displayed may be based on the capabilities of the electronic device. The shared workspace that is displayed may reflect the location of the electronic devices.

An improved system and method for using a file system to automatically backup a file in persistent storage is provided. A storage aggregator may organize nonvolatile memory for use in aggregate to store backup copies of a file. A file system filter driver may receive a request from an application for storing a file and may access a policy to determining whether to create a backup copy of the file and what type of backup to apply to the file. A generational file handler may create and manage a set of generational files as backup copies of a particular application file. And a recovery user interface may be provided to retrieve one or more backup copies, such as the set of generational files, for inspection by a user to recover whatever copy of the file may be desired by the user.

A method and system for configuring a new device are disclosed. The method includes using a host system to create a configuration file including data useable to configure the new device. A portable storage device is interfaced to the host and the configuration file is transferred to the storage device. The storage device is then interfaced to the new device and the configuration file is transferred to the new device. The configuration file is optionally used to configure the new device for communication over a network. A method for configuring the new device using a direct connection between the new device and a system bus of the host is also disclosed.

Described is a technology by which a computing device is booted into a normal mode of operation or a limited mode of operation, depending on whether the computing device was operating correctly (e.g., with respect to policy) prior to a reboot. The reboot may be forced. Examples of incorrect state include an overdue payment on a leased computer, or improper execution of certain important software. A metering mechanism evaluates the state of the computing device, and when an incorrect state is detected, configures the computing device for operation in the limited mode, by setting the computing device to boot via one boot path (e.g., a limited-mode BIOS) instead of another boot path (e.g., a normal-mode BIOS). A BIOS selector switches to the limited BIOS on the next reboot, wherein the computing device is restricted to the limited mode of operation (regardless of subsequent reboots) until the correct state is restored.

An auxiliary computing device normally used for remotely controlling a primary device may change its functionality and extend its usefulness based on a usage context. An auxiliary device may change its usage context by connecting differently to a primary device depending on any number of parameters including distance from the device, battery life, connection method, and proximity to other devices. The device may change its usage context by interfacing with a primary device service that communicates with various applications to feed the auxiliary device different information in different usage contexts. Further, the device may control different functions of the primary device based on the usage context.

A hardware-based security module is used to protect an electronic device, especially a portable electronic device. The security module may determine either via timeout of a watchdog timer or via an explicit message to encrypt selected data on the electronic device. In addition, the electronic device may enter a limited function mode that only allows display of simplistic messages and supports network traffic with a recovery service. The recovery service may be able to use the network traffic to locate the electronic device. The security module may include a secure memory, a cryptographic function, a timer, and support for direct display of data on a monitor.

A system and method for maintaining persistent data during an unexpected power loss uses a memory controller and a supplemental power source. An entity running on the computer, for example, an application program, a utility, the operating system or other entity, may identify data for preservation using an application program interface. The application program interface may be provided by the memory controller. A sensor determines when an unexpected power loss has occurred and signals the memory controller. Using power from the supplemental power source, i.e. a battery or capacitor, the memory controller copies the identified data to a non-volatile memory. The memory controller may set a flag to indicate that preserved data is available for later recovery.
