Abstract: A method for managing document revisions. The method includes receiving a request to access a parent file stored on a server, where the parent file is associated with one or more child files; determining whether a first option is enabled that is associated with selecting a latest version or revision of a child file, where a revision includes one or more versions; determining whether a second option is enabled, where the second option is associated with selecting a released version or revision of a child file; and, for each child file, providing access to a version or revision of the child file based on whether the first option is enabled and whether the second option is enabled.

Abstract: A method and apparatus for performing signal processing using incongruent buffers. According to one method described, a maximum concurrent run length (MCRL) is calculated to indicate the maximum run length before any of a plurality of buffers is exhausted. Processing data for each of the plurality of incongruent buffers is then repeated until the maximum concurrent run length has been reached. The calculation of the MCRL may be a determination of which of the plurality of buffers has a lowest remaining time before buffer exhaustion or the least number of remaining buffer entries. A system described includes a processor coupled to memory. The memory contains a plurality of buffer counters and a plurality of memory blocks defining a plurality of incongruent buffers. The memory also contains a MCRL calculation routine for determining the MCRL count from the buffer counters. A data processing routine repeats manipulations of data in the incongruent buffers until the MCRL count is reached.

Abstract: An audio stream is analyzed to distinguish silent periods from non-silent periods and an encoded bitstream is generated for the audio stream, wherein the silent periods are represented by one or more sets of canned encoded data corresponding to representative silent periods. In a preferred embodiment, one of the sets of canned encoded data is randomly selected for each silent period. There may be different sets of silent periods corresponding to different types of silent periods, where a particular type of silent period is selected based on some characteristic of the audio stream (e.g., energy level of the silent periods). In addition, the sets of encoded data may be generated from actual silent periods of the audio stream.

Abstract: One or more dynamically updated measures are generated for an audio stream. Processing is performed using the measures to distinguish silent periods from non-silent periods in the audio stream and the audio stream is encoded, wherein the silent periods are encoded differently from the non-silent periods. The processing is re-initialized during the encoding of the audio stream, if certain conditions are met. In a preferred embodiment, the processing is re-initialized if either of the following two conditions is met: (1) one of the non-silent periods is longer than a duration threshold or (2) an energy measure for the silent periods of the audio stream exceeds an energy threshold level.

Abstract: A self-apodizing collimator for collimating X-rays for use in VLSI lithography. The paraboloidal collimator uses a graded ML coating to collimate a range of wavelengths along the surface of the paraboloid such that a uniform resist response is provided. In addition, the collimated X-rays have a higher intensity than possible with a system using additional apodizing films.
