Title: Adaptive dynamic range optimisation sound processor
Inventor: MCDERMOTT HUGH JOSEPH
IPC: G10L15/02
Filed: 1999-02-05
Granted: 2008-10-14
Abstract: In one embodiment an apparatus for processing sound includes a means (401) for analysing a sound signal into a number of frequency bands and a means (403) for applying variable gain to each frequency band independently. Gain is applied under control of a number of gain comparator means (409) each of wich generates a number of statistical distribution estimates in respect of each signal and compares those estimates to predetermined hearing response parameters stored in memory (411). The numerous gain compensated frequency bands are then combined (415) in order to generate a single sound signal. The apparatus may be implemented in dedicated hardware embodiment or by software running on a microprocessor.

Abstract: In a vehicle remote-control system, an anti-theft unit includes a vehicle control module, which can receive a disarm signal directly from a signal transmitting key, and which can change from an armed state, in which an inactive state of an ignition system is maintained, to a disarmed state, in which the ignition system is activated, upon receipt of the disarm signal. A starting unit includes a starting device, which generates an enable signal upon receipt of a starting control signal from a remote controller, and which controls starting operation of the ignition system when the vehicle control module is at the disarmed state and the starting device receives the starting control signal . A signal connector is enabled by the enable signal so as to relay the disarm signal from the key to the vehicle control module.

Granted: 2007-01-16
Abstract: A fuel cell system 1 comprises a fuel cell stack 10, an evaporator 21, a reforming device 22, a supercharger 23, an offgas heating device 24, and a catalytic combustion chamber 25. Offgas exhausted from the fuel cell stack 10 is burnt in the catalytic combustion chamber 25, and the burnt offgas is introduced to the evaporator 21 to be heat exchanged with a reforming raw fuel and reforming air. The burnt offgas cooled by means of the heat exchange is introduced to the offgas heating device 24, to be used as a heat source for heating the offgas exhausted from the fuel cell stack 10. The offgas can be heated by the burnt offgas, and the moisture in the offgas can be vaporized and introduced to the catalytic combustion chamber 25. As a result, a reduction in the quantity of generated heat of the catalytic combustion chamber can be prevented in the fuel cell system.

Abstract: A method for imaging of a scattering target medium using a modified perturbation formulation of the radiation transport equation wherein normalized measured values are used to recover a relative difference in absorption and/or scattering properties based on the normalized measured values with respect to a reference medium. The modified perturbation formulation provides enhanced stability, reduces the sensitivity of solution to variations between the target and reference media, produces solutions having physical units and reduces the need for absolute detector calibration. Moreover, the modified perturbation equation lends itself to the detection and imaging of dynamic properties of the scattering medium.

Title: Stranded cable and method of making
Inventor: JOHNSON DOUGLAS E
IPC: H01B5/10
Filed: 2000-11-21
Granted: 2010-06-29
Abstract: A stranded cable that includes a plurality of brittle load bearing wires and a means for maintaining the stranded arrangement of the brittle wires. Because the load bearing wires are brittle, they cannot be sufficiently deformed during conventional cable stranding processes in such a way as to maintain their helical arrangement. Therefore, the means for maintaining the helical arrangement of the stranded wires allows the stranded cable to be conveniently provided as an intermediate article or as a final article. When used as an intermediate article, it may be later incorporated into a final article such as overhead power transmission cables. The maintaining means may be a tape, an adhesive tape, or a binder applied to the stranded wires.
