摘要： A programmable arbiter providing for dynamic configuration of prioritization schemes is implemented using a simple, but effective structure. One or more arbiter banks are structured in a cascading manner. Each arbiter bank receives a predetermined number of the set of bus requests to be arbitrated. Each bank is separately programmed to provide a rotating or fixed priority scheme to evaluate the priority of the bus requests. Thus by separately programming the arbiter banks to operate in a fixed priority or rotating priority manner, a flexible, programmable arbiter is created which can operate according to a fixed, rotating or hybrid priority scheme and is adaptable to a variety of applications.

摘要： In one aspect, a sterilizing lamp may include a lamp main body, a photocatalyst coating outside the lamp main body, and a CCFL light tube inside the lamp main body. The photocatalyst can be activated by the CCFL light passing out from the lamp main body. An emission material that generates the CCL rays may be enclosed in an internal space of the CCFL light tube. In one embodiment, the photocatalyst in the present invention is TiO2-based. For the specific photocatalyst used in the present invention, the most effective CCFL rays to activate the photocatalyst include a first CCFL ray with shorter wavelength and a second CCFL ray with longer wavelength.

摘要： An electronically tuned, wavelength-dependent optical detector is provided. The electronically tuned, wavelength-dependent optical detector is a modified metal-semiconductor-metal photodetector including a comb-like metal electrode at a common voltage and metal electrodes each supplied with a control voltage by a voltage means. The wavelength to be detected in an optical input illuminating the detector is selected based on the set of control voltages applied to the metal electrodes. In another embodiment of the invention, the wavelength to be detected with the electronically tuned, wavelength-dependent optical detector is also selected using a standing wave generator, such as an interferometer, to produce a spatially varying light intensity on the surface of the electronically tuned, wavelength-dependent optical detector. Electronic wavelength demultiplexing is also provided. Design flexibility can be obtained by providing two or more optical patterns at a detector surface, each pattern having a different wavelength dependence.

摘要： A method and system for reliably performing extra-long operations in a reliable state-full system (such as a file system). The file system includes a separate portion of the file system reserved for files having extra-long operations in progress, including file deletion and file truncation. This separate portion of the file system is called the zombie file space; it includes a separate name space from the regular (“live”) file system that is accessible to users, and is maintained as part of the file system when recording a consistency point.

摘要： The present invention provides a system, method and apparatus for improved electrical-to-optical transmitters (100) disposed within printed circuit boards (104). The heat sink (110, 200) is a thermal conductive material disposed within a cavity (102) of the printed circuit board (104) and is thermally coupled to a bottom surface (112) of the electrical-to-optical transmitter (100). A portion of the thermal conductive material extends approximately to an outer surface (120, 122 or 124) of a layer (114, 116 or 118) of the printed circuit board (104). The printed circuit board may comprise a planarized signal communications system or an optoelectronic signal communications system. In addition, the present invention provides a method for fabricating the heat sink wherein the electrical-to-optical transmitter disposed within a cavity of the printed circuit board is fabricated. New methods for flexible waveguides and micro-mirror couplers are also provided.

摘要： A system that manages a file system for a file server. A file operation is received that signals a reservation operation for a file having a file size. Preferably, the file system uses a write anywhere file system layout, the file operation that signals the reservation operation is a zero length write request, and the file operation that signals the reservation operation includes a parameter that specifies the file size. A number of blocks needed to be reserved to accommodate the file is computed. Preferably, computing the number of blocks needed to be reserved to accommodate the file includes determining a total number of direct and indirect blocks needed to accommodate the file size, and subtracting a total number of blocks already allocated for the file and a total number of cached unallocated blocks for the file from the total number of direct and indirect blocks needed to accommodate the file size. A number of unallocated blocks is reserved in the file system, with the number of reserved blocks equal to the number of blocks needed to be reserved to accommodate the file. Reserving the number of blocks preferably includes setting a flag in an inode for the file that indicates blocks have been reserved for the file, and incrementing a reserved block count in a file system information block by the number of blocks needed.
