Title: Wavelength multiplexed optical signal amplification control system
Inventor: HARANO HIROSHI
IPC: H04B10/40
Filed: 1998-04-24
Abstract: A wavelength multiplexed optical signal is input to an erbium doped fibre amplifier 3. A fraction of the input signal is split off at a coupler 1, demultiplexed by an arrayed waveguide 5, then the number of different wavelength signals in the multiplexed signal is detected by a photo detector array 9. This information, in combination with a standard feedback control system, 4 and 8, is used to control the level of amplification and to achieve a desired output level.

Title: Compressor with recessed reed valve
Inventor: BROWN GARY PETER
IPC: F04B39/06
Filed: 1998-07-23
Abstract: A piston and cylinder compressor has a valve plate 10 between an upper end of the cylinder 1 and a cylinder head 11, the valve plate having a generally diametrically located recess 16 at the inward surface thereof and inlet apertures 18. The recess accommodates a suction valve reed 17. Delivery valve reeds 23, 24 being located above apertures 21 to either side of the inlet valve. The recess can be formed: directly in the valve plate 10; in a gasket sealing between the valve plate and cylinder; or in a plate (35, Fig. 3) interposed between the valve plate and cylinder, the reed and plate being formed integrally. The arrangement minimises dead volume around the reed and hence the operating clearance volume of the compressor.

Title: Method and system for displaying greetings in a mobile radio comunications system
Inventor: MARSOLAIS PATRICE
IPC: H04W8/18
Filed: 1997-12-16
Abstract: There is disclosed a method and apparatus to displaying greetings to mobile terminals (30) identifying services associated with location based services. The system identifies a plurality of service zones (Z) in the system, and also transmits predefined services to mobile terminals when located in the service zones. The system transmits from each base station (32) local zone profile information to each of the mobile terminals located in those service zones. Each mobile terminal has stored (95) therein subscriber zone profile information for which that mobile terminal can receive location based services. The mobile terminal also stores (95) an associated greeting for each zone of subscriber zone profile information. The mobile terminal compares (97) transmitted local zone information with the list of stored subscriber zone profile information, and when a match is found, the mobile terminal displays (96) the greeting associated with the subscriber zone profile information. By storing the associated greeting in the mobile terminal, the otherwise signaling of greeting information over the air interface is avoided.

Title: Assessing deterioration of a NOx catalytic converter
Inventor: BERGER JOACHIM
IPC: G01N33/00
Filed: 1999-09-15
Abstract: The performance of a NO<SB>x</SB> catalytic converter for an i.c.e. degrades during its lifetime. The NO<SB>x</SB> trap is subject to repeated cycles of lean-burn fumes (NO<SB>x</SB> absorbed) and rich-burn fumes (NO<SB>x</SB> desorbed and reduced). As the NO<SB>x</SB> catalyst ages it is poisoned by SO<SB>x</SB>, and its cells become contaminated, so that it absorbs less NO<SB>x</SB> in each lean-burn phase. By placing a NO<SB>x</SB> sensor downstream of the NO<SB>x</SB> trap the ever-shortening time period of absorption and desorption steps can be measured, and from this the limited capacity of the NO<SB>x</SB> trap deduced. Real-time measurements for purging or charging periods, or for NO<SB>x</SB> mass flow, can be compared with threshold values determined when the NO<SB>x</SB> trap was new, and thereby indicate if the device is defective.

Title: Storing spectral data from mass spectrometers
Inventor: FRANZEN JOCHEN
IPC: H01J49/02
Filed: 1999-10-05
Abstract: The invention consists of combining all or selected daughter and granddaughter spectra of a parent ion in an ion trap over several generations in one combined descendants spectrum. This combined descendants spectrum can be depicted as a graphic or a list. The references to origin can be plotted on the combined descendants spectrum. For biopolymers, where the loss of fragments can be identified due to their mass, the names or abbreviations of lost molecule fragments can be entered. The criteria for selection of the spectra can be predefined; in this way, the spectra can be depicted and even scanned automatically. The combined descendants spectrum facilitates comparison with spectrum library data from other types of mass spectrometer, e.g. tandem in space mass spectrometers, to enable identification or structural elucidation of the parent ion.
