| 20110055271 | Systems and Methods for Providing Information for Use in a Runtime Computing Environment - Systems and methods for providing information for use in a runtime environment that restricts access such information. An executable is launched prior to launching the runtime environment or runtime application. The executable retrieves information and makes that information available for use in the runtime, for example, by storing the information in a runtime file system area. The runtime or runtime application can then access the information. For example, the executable may retrieve information from a host operating system and then launch a runtime application that uses the information. An application that executes within a runtime and requires runtime external information can be provided as a bundle that includes an executable and the application itself. When the bundle is launched, the executable executes first to retrieve the information and make it available for the runtime. The runtime is then launched and provides the runtime application which can use the information. | 03-03-2011 |

| 20100188058 | Reference Voltage Generation for Single-Ended Communication Channels - An improved reference voltage (Vref) generator useable, for example, in sensing data on single-ended channels is disclosed. The Vref generator can be placed on the integrated circuit containing the receivers, or may be placed off chip. In one embodiment, the Vref generator comprises an adjustable-resistance voltage divider in combination with a current source. The voltage divider is referenced to I/O power supplies Vddq and Vssq, with Vref being generated at a node intervening between the adjustable resistances of the voltage divider. The current source injects a current into the Vref node and into a non-varying Thevenin equivalent resistance formed of the same resistors used in the voltage divider. So constructed, the voltage generated equals the sum of two terms: a first term comprising the slope between Vref and Vddq, and a second term comprising a Vref offset. Each of these terms can be independently adjusted in first and second modes: the slope term via the voltage divider, and the offset term by the magnitude of the injected current. Use of the disclosed Vref generator in one useful implementation allows Vref to be optimized at two different values for Vddq. | 07-29-2010 |

| 20090044204 | Application programming interfaces for transacted file and registry operations - A set of application programming interfaces (“APIs”) is provided that enables an application to perform operations on multiple system resources as a single logical unit of work through a transaction. The application can then commit or roll back the entire group of changes as a single unit in a coordinated manner. The APIs expose functions and methods that take a reference to a transaction context, such as a handle, name, or pointer, as one of their parameters so that the application can manipulate the resource as a transacted operation. The transaction is bound to all created handles so that all operations on the resource using those handles are also transacted. In an illustrative example, the set of APIs are transacted name-based WIN32 APIs that take a transaction handle. The transacted APIs expose transacted operations to the application for durable system resources in the OS kernel, including the NTFS file system (New Technology File System) and registry. | 02-12-2009 |
