Title: Erbium doped fibre amplifier with same gain change characteristic at different wavelengths
Inventor: NILSSON LARS JOHAN ALBINSSON
IPC: H04B10/294
Filed: 1996-02-23
Abstract: An erbium doped fibre amplifier has a gain medium with a characteristic such that, if the gain changes at one wavelength, the gain at another wavelength changes by substantially the same amount. The characteristic may be achieved by using a gain medium with this property or by the construction of the amplifier. The gain medium can be an erbium-doped fibre with a wavelength independent gain swing over a range of wavelengths (especially a low Al 3+ -content aluminogermanosilicate EDF). As an alternative, the gain medium can consist of at least two pieces of EDF's, so that changes of the shape of the gain spectra (induced by changes of the operating conditions) in the different types of EDFs effectively offset each other. The gain spectrum can also be modified by means of optical filter(s) 3 placed before and/or after, between two sections of, and/or distributed along the gain medium, or by means of a "filtering EDF", specially selected in a constant population inversion region of the EDFA. The gain spectrum thus obtained is both flat and independent of operating conditions so that a dynamic gain flatness which is independent of input signal power, operating gain, and population inversion is realised.

Title: Method and system for changing rating data via internet or modem in a carrier management system
Inventor: BOUCHER GLEN A
IPC: G06F17/30
Filed: 1998-09-30
Abstract: The invention is a method and system of updating a set of data objects within a Data Access System (DAS). The method begins by initiating (600) a communication link between a client and a host data processing system. Once a communications link is established, a set of object tables is uploaded (602) from the client data processing system to the host. The object tables are read (604) at the host; and, a determination is made (606,608) as to which data objects in the set of object tables are to be updated. It is also determined which data objects in the set of object tables is to be simply maintained (612). A new set of object tables is then constructed (614) at the host data processing system and transmitted (616) to the client data processing system. Upon receipt of the new file tables, the client system performs the task of verifying (618,620) accurate receipt of the new set of object tables prior to restarting (622) the client data processing system. The verification step includes saving at the host, a first data map of the new set of object tables as a record of which objects were transmitted. The new set of object tables is then received and saved within a memory of the client data processing system before retransmitting the new set of object tables as a second data map back to the host from the client The second data map is then compared with the first data map to form a comparison, and if the first data map and the second data map do not match, then the verification is nulled.

IPC: G06T7/60
Filed: 1998-12-03
Abstract: Examination and analysis of a microbiological test in which locations of a micro-organism in or on a nutrient gel can be differentiated for locations wherein growth is inhibited. Imaging of the surface roughness caused by the microbial growth using a camera produces a pixel map 30 where the pixel values vary according to the surface roughness. The image pixel map is processed to emulate a multiplicity of differently orientated radial scans 32 of a region of the surface, wherein a specified number of pixels in each scan line (40) represents the same physical distance. The scan lines (40) may be further processed to measure the dimension of the region, and this processing may comprise assembling the scan lines such that the centre (41) and periphery (42) of the surface region are each represented by a respective lines (51, 52). The test may be for comparing susceptibility of micro-organisms to antibiotics. The sample region in the gel (1) may have a central mark (2) and a circular boundary (4) of a region (3) of growth, the extent of the growth being the radial dimension of the circle.
