Abstract: A transmission method for implementing variable rate transmission. Part of the baseband processing of a transmitter based on a CDMA transmission scheme is described. A transmitted information sequence in the form of a digital signal is phase modulated by a phase modulator 105. An orthogonal code generator 101 selects, in response to rate information of the transmitted signal, the orthogonal code to be generated. The bit rate of the orthogonal code the orthogonal code generator 101 generates is double the maximum transmission rate. The modulated transmitted signal is multiplied by the orthogonal code corresponding to the rate information with a multiplier 103. The transmitted signal, which is multiplied by the orthogonal code corresponding to the rate information, is further multiplied by a spreading code sequence with a multiplier 104 to be spread into a CDMA signal, and is transmitted under power transmission control based on the rate information.

Abstract: A network configuration protocol and algorithm are described which resolve deficiencies with existing protocols. A large network having many bridges may be built as a combination of smaller networks, many of which may each be arranged in a ring topology. Each ring may be monitored by a single master bridge regularly sending control packets, and each other bridge in the ring does not make decisions with respect to its status. A loop free topology is achieved by selectively blocking and unblocking data traffic in one of the ring ports of the single master bridge for the ring, while all other bridges in the ring keep their ports in non-blocked states. In multiple ring topologies, each ring has a single master bridge which chooses one of its ports to be blocking.

Abstract: A bearing arrangement for a gear pump comprises first and second separate bearing blocks each having a respective block housing. The first and second bearing blocks together defining an axially directed bearing surface including a bridge region formed from an erosion resistant material which acts to separate inlet and outlet ports of the pump and a second region formed from a reduced friction material. The bridge region is defined by first and second insert members cast within respective ones of the block housings. The first and second bearing blocks are arranged such that respective surfaces of the first and second insert members mate with one another, and the first and second insert members are arranged such that the bridge region of the bearing surface is flush with the second region.

Abstract: A system for transmitting images and methods of manufacturing and using the same. The system for transmitting images includes a camera, a fiber optic cable, and a display system. The camera comprises a lens system for receiving light signals from one or more still and/or moving objects to be imaged. Upon receiving the light signals, the lens system intensifies the light signals to produce a substantially-reduced image of the objects and communicates the entire substantially-reduced image in real-time to a lens system of the display system via a single filament of the fiber optic cable. The lens system of the display system then deminiaturizes (or magnifies) the substantially-reduced image to produce an expanded image of the objects. The expanded image, which is continuously updated by the lens system of the camera to generate real-time still and/or moving images, is visibly presented by the display system.

Abstract: A highly compact and easily fabricated band pass filter is disclosed. A band pass filter according to the present invention employs a first half-wave (&lgr;/2) resonator having a first open end on which an input terminal is formed and a second open end opposite to the first open end, a second half-wave (&lgr;/2) resonator having a third open end on which an output terminal is formed and a fourth open end opposite to the third open end, and an evanescent waveguide interposed between the second open end of the first resonator and the fourth open end of the second resonator. The first half-wave (&lgr;/2) resonator, the second half-wave (&lgr;/2) resonator, and the evanescent waveguide being single-unit. An air gap does not have to be formed by mounting components on a printed circuit board. Therefore, the overall size of the band pass filter can be miniaturized and fabrication of the band pass filter is simplified.

Abstract: A process for constructing a server for collecting, arranging and storing data that defines the connectivity of pages on the World Wide Web (Web). The process input is a set of compressed ASCII links files, wherein each links file is a series of source URLs and corresponding destination URLs. A temporary URLs_info Table is created and initialized. The links files and URLs metadata are read. Buffers of unique URLs are sorted and written from the links files into URL runs. An ID Index is created from the URL_info table. CS_ids are assigned to URLs and written to the ID Index. Both a compressed URL data structure and a URL Index are created. A Host Table is created. URL fingerprints are converted to CS_ids, and preliminary outstarts to CS_ids and preliminary outstarts and outlinks tables are created. Compressed outstarts and outlinks tables are created from the preliminary tables. Subsequently, compressed instarts and inlinks tables are created based on the outstarts and outlinks tables.

Abstract: A system and method for automatically reallocating resources among partitions based on factors including relative resource pain rates and user assigned priority. A tuner executes several tasks, including determining relative memory pain rates for partitions and allocating memory among partitions so that future relative memory pain rates obtained after the allocation will be more evenly distributed among the partitions than current relative memory pain rates are distributed. Also, the tuner determines current relative processor and interactive pain rates for partitions and allocates processor and interactive power among these partitions so that future relative processor and interactive pain rates obtained after the allocation will be more evenly distributed among the partitions than current relative processor and interactive pain rates are distributed.

Abstract: A short cell multiplexing is provided for chiefly transmitting data shorter than the payload of a standard ATM cell (basically the data of less than 48 bytes, but the data more than 48 bytes can be allowed). A standard ATM cell assembler 1 converts various forms of input information into short cells, places the short cells in standard ATM cells efficiently considering their information length, and output them to a B/ISDN network 7. The standard ATM cell disassembler 2 disassembles the standard ATM cells, which are assembled by the standard ATM cell assembler 1 and is input through the B-ISDN network 7, into short cells, converts the short cells into those with the original input information forms, and outputs them to channels. The configuration makes it possible for the short cell ATM cell multiplexing to improve channel efficiency with small delay, and matching to the standard ATM system.
