Title: Optical Device
Inventor: DAVIES DAVID ARTHUR OWEN
IPC: H01S5/02
Filed: 1995-09-14
Abstract: An optical device for use as an amplifier or modulator comprises a semiconductor substrate (2) with an elongate waveguide region (1) with a light guiding boundary that extends between an input (3) and an output (4) for optical radiation. An optically active layer of material (6) produces amplification of light travelling inthe waveguide region (1). The width (w) of region (1) tapers outwardly from the input to allow amplification of input optical signals, and tapers towards the output (4) so as to concentrate the amplified light in a single mode to the output. The concentration of the amplified light in the active region may produce non-linear effects which are exploited in order to achieve data modulation or switching. In one embodiment, the waveguide region includes a first active region (30) to produce optical amplification, and a second passive region (31) for concentrating light to the output.

Inventor: SMITH WILLIAM DAVID
IPC: B60L3/00
Filed: 1997-11-06
Abstract: The present invention discloses a system and method for isolating failures in a locomotive. In the present invention, the cause of failures occurring in the locomotive sub-systems are determined quickly and efficiently, while minimizing the need for human interaction. However, the present invention can incorporate information provided by an operator to produce a more refined diagnosis. In the present invention, incidents are recorded in an incident log and mapped to indicators, which are sent to a fault isolator for diagnosis. The fault isolator uses a diagnostic knowledge base having diagnostic information between failures occurring in locomotive and observable symptoms happening therein. A diagnostic engine then processes the mapped indicators with the diagnostic information in the diagnostic knowledge base and produces a list of the most likely causes for any failures. The present invention then provides a course of action to correct the failures.      The present invention can also be used to automatically isolate and diagnose failures occurring in process having a plurality of equipment.

Title: Selective removal of volatile substances injected into a chromatographic packing filled column
Inventor: BERTRAND MICHEL
IPC: G01N30/00
Filed: 1995-06-23
Abstract: In the apparatus of the invention a flow of a carrier gas through a column is provided. A sample is provided in the column, and a temperature of a longitudinally short portion of the column is raised to a predetermined controlled high temperature at which volatile substances are released from the sample packing and are carried by the carrier gas. The column is cooled on each side of the short portion to a low temperature at which the volatile substances condense or adsorb on the column packing. By continuously moving the heated short portion from an inlet end to an outlet end of the packing in a direction of carrier gas flow the volatile substances selected by controlled high temperature are released. Four particularly useful and advantageous applications can be identified for the invention. Firstly, it can be used to provide an improved gas chromatograph (GC) injector. Secondly, it can be used to provide an improved thermal separator or extractor. Thirdly, it provides an efficient way to analyze target compounds (Target Compound Analysis or TCA mode) suspected of being contained within a complex mixture by allowing for the GC analysis to be carried out only on those compounds or substances falling within the same or similar thermal desorption characteristics as those of the target compound. Lastly, by operating in a full time-coupled time-resolved (TCRC) mode, a complete three-dimensional analysis output can be obtained giving better power of separation of the analyzed sample, which is of particular importance when the substance to be analyzed is a complex organic material.

Title: An enhanced echo canceller for digital cellular application
Inventor: HO DOMINIC KING-CHOI
IPC: H03H21/00
Filed: 1996-11-25
Abstract: An echo cancelling system for communication systems. The system includes an adaptive filter (34) that processes the speech signal re-constructed by a speech decoder (30) to generate an echo estimate. The echo estimate is subtracted from the echo containing signal propagating in the communication link to remove or at least reduce the echo corruption. The tap coefficients of the adaptive filter are established on the basis of an error signal that is representative of difference between the echo estimate and the actual echo and on the basis of a signal element that is a component of the re-constructed speech signal. The signal element is highly decorrelated using a decorrelation filter (38) to enable the adaptive filter to converge faster and manifest an improved echo return loss enhancement.

The apparatus includes an error signal generator and a detector. The error signal generator has an input for receiving a reference signal having a reference frequency, a second input for receiving the arbitrary signal having the signal component and an output for generating a difference signal dependent upon a difference in frequency between the reference frequency and the desired frequency. The detector has an input for receiving the difference signal and an output for producing a detector signal when the magnitude of the difference signal is greater than a threshold magnitude. The detector signal indicates the presence of the signal component in the arbitrary signal.
