Abstract: Aspects of the subject matter described herein relate to error detection for files. In aspects, before allowing updates to a clean file, a flag marking the file as dirty is written to non-volatile storage. Thereafter, the file may be updated as long as desired. Periodically or at some other time, the file may be marked as clean after all outstanding updates to the file and error codes associated with the file are written to storage. While waiting for outstanding updates and error codes to be written to storage, if additional requests to update the file are received, the file may be marked as dirty again prior to allowing the additional requests to update the file. The request to write a clean flag regarding the file may be done lazily.

Abstract: Aspects of the subject matter described herein relate to checkpoints for a file system. In aspects, updates to the file system are organized into checkpoint buckets. When a checkpoint is desired, subsequent updates are directed to another checkpoint bucket. After global tables have been updated for updates in the current checkpoint bucket, a logical copy of the global tables is created. This logical copy is stored as part of the checkpoint data. To assist in recovery, a checkpoint manager may wait until all updates of the current checkpoint bucket have been written to storage before writing final checkpoint data to storage. This final checkpoint data may refer to the logical copy of the global tables and include a validation code to verify that the checkpoint data is correct.

Abstract: Light emitting system (100), particularly, light emitting systems that utilize semiconductor wavelength converting regions (104), and methods of producing such systems are disclosed. The light emitting systems and methods of producing such systems seek to frustrate recombination of free carriers that are associated with wavelength converting regions.

Abstract: Aspects of the subject matter described herein relate to querying and repairing data. In aspects, a component may detect that data on storage has become corrupted. In response, the component may request data from one or more redundant copies of the data and may determine which of the redundant copies, if any, are not corrupted. If a non-corrupted copy is found, the component may send a request that the corrupted data be repaired and may identify the non-corrupted copy to use to repair the corrupted data.

Abstract: Light emitting systems are disclosed. More particularly light emitting systems that utilize wavelength converting semiconductor layer stacks, and preferred amounts of potential well types in such stacks to achieve more optimal performance are disclosed.

Abstract: The present invention is for a firearm sound suppressor which is attached to the barrel of a firearm to reduce the noise and flash generated by the firearm. The firearm sound suppressor improves the dissipation of heat and provides a breach head on the end thereof for use as a ramming and breaching instrument.

Abstract: A transactional file system wherein multiple file system operations may be performed as a transaction. An application specifies that file system-related operations are to be handled as a transaction, and the application is given a file handle associated with a transaction context. For file system requests associated with a transaction context, a file system component manages operations consistent with transactional behavior. Logging and recovery are also facilitated by logging page data separate from the main log with a unique signature that enables the log to determine whether a page was fully flushed to disk prior to a system crash.

Abstract: Aspects of the subject matter described herein relate to maintaining consistency in a storage system. In aspects, one or more objects may be updated in the context of a transaction. In conjunction with updating the objects, logical copies of the objects may be obtained and modified. A request to write the updated logical copies is sent to a storage controller. The logical copies do not overwrite the original copies. In conjunction with sending the request, a data structure is provided for the storage controller to store on the disk. The data structure indicates the one or more objects that were supposed to be written to disk and may include verification data to indicate the content that was supposed to be written to disk. During recovery, this data structure may be used to determine whether all of the object(s) were correctly written to disk.

The first mirror (120) is substantially reflective at the second wavelength and includes a first multilayer stack. The second mirror (160) is substantially transmissive at the first wavelength and partially reflective and partially transmissive and the second wavelength. The second mirror includes a second multilayer stack.
