Abstract: It has been demonstrated that B containing glasses are sensitive to radiation in the band 225-275 nm and, therefore, B2O3 glasses are particularly adapted to receive refractive index modulation, e.g., to make reflection gratings. Glasses containing SiO2 and B2O3, are particularly suitable when the grating is to be localised in the cladding of a fibre. Glasses containing SiO2, GeO2 and B2O3 are suitable when the grating is in the path region of a waveguide, e.g., in the core of a fibre.

Abstract: A method for obtaining a report from a mobile station on the status of frames comprising an entire message transmitted to the mobile station is disclosed. First, a polling request is sent to the mobile station from a base station. A status report is then sent to the base station. The polling request specifies whether the mobile station should send the status report on a reservation basis (using a reserved frame) or on a contention basis (using an idle frame). The mobile station then transmits a bit map to the communication system to indicate which frames have been correctly received by the mobile station at the point when it received the polling request.

Abstract: A recyling automated banking machine (ATM) including note feeding apparatus for properly orienting and quickly identifying notes deposited therein. Con-ventional recyling ATMs rely upon special features in-cluded in the currency note for identification. Accord-ingly, identification of currency notes not possessing such special features, e.g., U.S. notes, render quick identification difficult, particularly where the note is worn. The present invention overcomes these draw-backs by using a note feeder that can surely separate and properly orientate notes from a deposited note stack. The feeder includes a tray (74) for moving a stack toward an angled wall (170) for splaying the stack, reversible pick belts (78), stripper rollers (176, 178) for corrugating the notes, and a strip back stop (166). The separated notes are fed to a deskewing and aligning device.

Title: Local area network computer system utilizing radiating transmission line
Inventor: WAYE PATRICK M Y
IPC: H04H20/00
Filed: 2000-08-04
Granted: 2011-07-05
Abstract: A radio frequency communication system utilizing a radiating transmission line for communicating data signals is disclosed. The data signals convey digital data to remotely located data devices, including computers, equipment control systems and digital video cameras. The data signals have a wide bandwidth of about 0.5 MHz to 32 MHz. In this way, the communication system creates a local area network by means of the radiating communication line. The communication system is intended to be used in environments where radio waves do not propagate well, such as in underground environments, and in particular mines. The communication system comprises at least one amplifier connected to the radiating transmission line for periodically amplifying the data signals by demodulating the data signals to recover the data contained therein and then modulating the recovered data into a regenerated radio frequency at a power level permitting transmission and radiation of the regenerated radio frequency data signal. The regeneration amplifiers comprise a processor for temporarily storing and performing error detection and correction functions on the recovered data.   The regeneration amplifiers also comprise a device for tracking the data devices within the coverage area of the regeneration amplifier. Information regarding the data devices within the coverage area of each regeneration amplifier is sent to a system server of the communication system and the system server utilizes this information to account for delays caused by the regeneration amplifier. The communication system may support cable modem protocols such as DOCSIS.

Abstract: A method and apparatus are disclosed for releasing functional units in a multithreaded very large instruction word (VLIW) processor. The functional unit release mechanism can retrieve the capacity lost due to multiple cycle instructions.  The functional unit release mechanism of the present invention permits idle functional units to be reallocated to other threads, thereby improving workload efficiency.  Instruction packets are assigned to functional units, which can maintain their state, independent of the issue logic. Each functional unit has an associated state machine (SM) that keeps track of the number of cycles that the functional unit will be occupied by a multiple-cycle instruction. Functional units do not reassign themselves as long as the functional unit is busy. When the instruction is complete, the functional unit can participate in functional unit allocation, even if other functional units assigned to the same thread are still busy.   The functional unit release approach of the present invention allows the functional units that are not associated with a multiple-cycle instruction to be allocated to other threads while the blocked thread is waiting, thereby improving throughput of the multithreaded VLIW processor. Since the state is associated with each functional unit separately from the instruction issue unit, the functional units can be assigned to threads independently of the state of any one thread and its constituent instructions.
