Title: Optical wavelength dependant routing interface with wavelength reconfiguration
Inventor: SHARRATT MICHAEL
IPC: H04Q11/00
Filed: 2000-02-18
Abstract: The invention provides a transponder interface (1400,) for an optical communication system comprising a plurality of mutually interconnected bi-directional optical waveguide rings (20, 30, 40, 50, 60) in which radiation modulated with communication traffic propagates. The radiation is partitioned into 32 distinct wavebands. Interfaces (70, 80, 90, 100, 110, 120, 1200, 1400, 1500) are included in the system where communication traffic propagating in the rings transfers from one ring to another. Each interface (70, 1400, 1500) is capable of providing an all-optical waveband reconfigurable communication link between the rings (20, 30, 40, 50, 60). At each interface (70, 1400, 1500), conversion of optical radiation to corresponding electrical signals is not required when transferring communication traffic from one ring to another and from waveband to another, thereby providing the system with a potentially larger communication bandwidth compared to conventional optical communication systems. Radiation passing through the interface (1400) may have its wavelength changed in transponder (1410).

Title: Frame based transmission system where only part of the overhead is error correction coded
Inventor: TEZUKA HIROSHI
IPC: H04J3/00
Filed: 2000-06-16
Abstract: In a frame based transmission system such as SONET or SDH the overhead data is divided into a first selected overhead portion which is subject to error correction coding along with the frame payload and a second non-selected overhead portion which is not error correction coded. This second portion is typically network management overhead. The frames are produced by inserting the selected overhead portion into the frame, error coding it with the payload and then inserting the non-selected overhead portion and received frames are processed in the reverse fashion (see Fig. 3). As a result the network management overhead can be terminated and forwarded at a network repeater without the need for error correction decoding, reducing the complexity of repeater hardware required (See Fig. 5). A mixture of these simplified repeaters and those capable of performing error correction (See Fig. 7) can be used in the transmission path as required to achieve the required overall BER.

Title: Blood pump and control system
Inventor: PREM EDWARD KARL
IPC: A61M60/822
Filed: 2000-02-02
Abstract: A blood pump 51 for assisting a heart is provided by a stator and a rotor. The rotor is rotated relative to the stator by a motor. The blood pump apparatus includes a flow rate controller 92 and a flow rate sensor 91 to avoid excessively low or reverse flow through the pump when a pulsatile flow rate is provided. The flow rate controller may include a heart caliper 400/500 for measuring the dimension of a heart ventricle to control the flow rate to avoid overly distending or contracting the ventricle. The caliper 400/500 comprises two caliper arms positioned at opposing sides of the ventricle. Measurement of the ventricle dimension may be achieved by an angular measurement device measuring changes in the angle between the arms (fig 9) or by a pair of ultrasonic transducers located at opposite sides of the ventricle (504, 505, figs 10a and 10b). The motor for the pump may comprise a magnetic drive comprising a permanent magnet (31 fig 1a) armature windings (32, fig 1a) and back-iron (33, fig 1a). The rotor may be suspended in the stator by a magnetic suspension comprising two permanent magnet arrays (11, 12 fig 1a). The rotor may be axially supported by a Lorentz-force bearing (13-18, fig 1a). The pump may also include an axial position actuator engaged with the stator or rotor to permit the axial alignment between the stator and rotor to be adjusted.

Title: Binder resin including parting agent and synergist and process of making lignocellulosic articles
Inventor: MENTE DONALD CHARLES
IPC: C08G18/76
Filed: 2001-08-01
Abstract: A method for preparing compression molded or pressed lignocellulosic articles involves forming a binder resin by combining in specified proportions a polyisocyanate component with a parting agent and preferably a synergist. The parting agent is the reaction product of an isocyanate compound and an isocyanate-reactive compound of the general structure R-(ao)<SB>n</SB>-Y where R is a hydrophobic group containing higher alkyl, alkaryl, polyaryl or siloxane moieties; (ao) is a C<SB>2</SB>-C<SB>4</SB> alkylene oxide or mixture of C<SB>2</SB>-C<SB>4</SB> alkylene oxides; n is from 1 to 25; and Y represents a monofunctional isocyanate-reactive group. A resinated lignocellulosic mixture is formed by combining the binder resin in specified proportions with lignocellulosic particles. Then, a compression molded or pressed lignocellulosic article is formed by compressing the resinated lignocellulosic mixture at an elevated temperature and under pressure. It is particularly preferred that the binder resin further include a synergist of either a C<SB>1-4</SB> N-alkylpyrrolidone, gamma-butyrolactone, or a mixture of them. The most preferred synergist is N-methyl-2-pyrrolidine.

Title: Computer input device sterilization method and apparatus
Inventor: ROBERTS JON L
IPC: A61L2/10
Filed: 2000-01-10
Abstract: A computer input device sterilization apparatus having ultraviolet sterilization in an enclosed container to kill bacteria and other disease carrying organisms. The invention comprises a horizontal or vertical container dimensioned to fit over computer input devices such as keyboards, mice, trackballs, touchpads and the like. An ultraviolet source within the container irradiates the computer input device with UV light which, in one embodiment generates ozone gas, thereby killing any microorganisms that might reside on the computer input devices. Ultraviolet radiation below 200 nm can also be used thereby creating ozone gas having germicidal characteristics. The ozone gas is circulated in and around the input device thereby providing further sterilization together with the ultraviolet radiation. A sterilization switch turns the UV source off when the container is opened. A timer/power circuit provides the times application of power to the UV lamps to provide UV illumination consistent with the substantial sterilization of the input device in question.

Title: Voice activity detector and validator for noisy environments
Inventor: EALEY DOUGLAS RALPH
IPC: G10L25/78
Filed: 2002-01-24
Abstract: A communication unit (100) includes an audio processing unit (109) having a voice activity detection mechanism (130, 135). The voice activity detection mechanism (130, 135) measures an energy acceleration of a signal input to the communication unit (100) and determines whether said input signal is speech or noise, based on said measurement. A method of detecting voice and a method of deciding whether an input signal is voice or noise are also described. Using an energy acceleration based voice activity detector and validator, particularly for noisy environments, provides the advantages of noise robustness, fast response and independence of the level of input speech.

Title: Mechanism for handling failing load check instructions
Inventor: ARORA JUDGE K
IPC: G06F9/38
Filed: 2000-11-20
Abstract: A mechanism is provided for recovering from a failing load check instruction in a processor that implements advanced load instructions. An advanced load address table (ALAT) tracks status information for the advanced load instruction. The status information is read when an associated load check operation is processed, and an exception is triggered if the status information indicates data returned by the advanced load operation was modified by a subsequent store operation. The load check instruction is converted to a load operation, instructions are flushed from the processor's instruction execution pipeline, and the pipeline is resteered to the first instruction that follows the load check instruction.
