摘要： 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.

摘要： A pay-per-use computer, or other electronic device that uses local security, may use a security module or other circuit for monitoring and enforcement of a usage policy. To help prevent physical attacks on the security module, or the circuit board near the security module, a second circuit may be mounted over the security module to help prevent access to the security module. Both circuits may be mounted on a interposer and the interposer mounted to the circuit board, creating a stack including the first circuit, the interposer, the security module, and a main PC board. When the PC board includes dense signal traces under the security module a three dimensional envelope is created around the security module. When the first circuit is a high value circuit, such as a Northbridge, the risk/reward of attacking the security module is increased substantially and may deter all but the most determined hackers.

摘要： A computer is adapted for use in different operating modes by configuring an output controller, such as a graphics processing unit, to screen output signals prior to presenting them to the output device. A secure environment in the output controller verifies a digital signature or a hash of the output signal to determine whether the output signal is compatible with the current mode of operation. Thus only authorized output signals are presented when the computer is operating in a limited function mode, such as when metered usage time is expired. The apparatus and method also disclose similar output signal screening for determining whether the computer should be returned from a standby, or no-metering, mode to an active, or metered mode.

摘要： A security module for a pay-per-use computer supplies an appropriate BIOS for a given mode of operation. A power manager in the security module powers only essential circuits until the BIOS is operational to help prevent substitution of a non-authorized BIOS. The security module also includes a capability to monitor and restrict data lines on a bus between a main computer processor and computer system memory. When the computer is operating in a restricted use mode, data lines may be restricted to allow only minimal access to the computer system memory. Bus transactions may be monitored to ensure that only valid transactions are occurring and are within the designated memory space.

摘要： 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.

摘要： 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.

摘要： Light guide techniques are described. In one or more implementations, an apparatus includes a housing, a light guide supported by the housing, a light engine disposed within the housing and optically coupled to the light guide, and one or more modules disposed within the housing and implemented at least partially in hardware. The one or more modules are configured to cause the light engine to output a user interface for display using the light guide along an image plane focused at infinity.
