Title: Electromagnetic flowmeter
Inventor: KEECH RAY
IPC: G01F1/60
Filed: 1997-12-19
Abstract: In an electromagnetic flowmeter, the conventional derivation of flow velocity is corrected or replaced by an alternative calculation to take into account estimated non-linear dependence of field strength produced by the coil with applied coil current. This can be used to enable more accurate measurement, over a wider range of coil current. The improved accuracy allows the coil current to be adjusted to optimise power consumption. A method of adjusting coil current in dependence on flow rate such that a higher current is applied at a lower flow rate and vice versa is also disclosed.

Patent GB-2341046-A (GB)
Title: Transponder identification system
Inventor: REGAN BERNARD JOHN
IPC: G07C9/00
Filed: 1998-07-28
Abstract: The system seeks to speed up the identification of transponders 12, 14, 16 by identification or interrogating devices 2, 4 in situations in which the devices 2, 4 may have overlapping detection fields 6, 8. The devices 2, 4 may initially be operated simultaneously (in non-exclusive mode) for each device to determine the identities of any transponder in its field. A transponder 14 in an overlap region 10 of the fields 6, 8 may not be identified during this process because the conflicting signals received by transponder 14 from devices 2, 4 may interfere. The devices 2, 4 are therefore next operated sequentially (in exclusive mode). For each transponder which it has identified itself, a device, such as device 2, then establishes an identification code which when transmitted in whole or in part will cause the transponder to provide a distinguishing response. This code may be the unique ID code of the transponder, but is preferably an abbreviated code. As device 2 transmits an abbreviated code to each of its respective transponders in the exclusive mode, the or each other device 4 obtains the full identity of each such transponder, either over a dedicated communications channel between the devices 2, 4 or by monitoring the transmissions made by device 2 to the transponders. Identification device 2 then tests whether any transponder already identified, either by itself or by another identification device 4, lies within its respective detection field. Once this has been done by device 2, another identification device 4 begins its own independent operation. The entire process, commencing with the simultaneous operation of devices 2, 4, is then repeated periodically.

Patent GB-2342472-A (GB)
Title: Process monitoring in a computer system
Inventor: BROWN ROGER S
IPC: G06F11/28
Filed: 1998-10-09
Abstract: The health of a process is monitored in a computer system by a process monitor 460. The monitored process (a configuration management system daemon (CMSD) 400) is not a child of the process monitor. The process monitor uniquely determines the identity of a monitored process and verifies the correct operation of the monitored process. In the absence of verification of the correct operation of the monitored process, the monitored process is caused to initiate. On successful initiation of the monitored process, the monitored process is uniquely identified to the system and is detached from the process monitor. Each monitored process is arranged to write, on initiation, its unique process identification information (PID) 450 to a file (452, Figure 12) which file is then accessed by the process monitor to determine the PID for the CMSD 400.The PID is unique to the actual invocation of the CMSD 400, and may not be confused with a simple name which may be associated with various versions of the CMSD 400, or with another process, or even with another process or program masquerading as the CMSD 400. The process monitor may interrogate the operating system to verify correct operation of the CMSD. As an alternative, the process monitor could test whether the CMSD is functioning by making service requests to the CMSD.

Title: Mass spectrometry method for accurate mass determination of unknown ions
Inventor: KOESTER CLAUD
IPC: H01J49/00
Filed: 1999-01-28
Abstract: A method for the accurate determination of the position co-ordinate, that is the location, frequency or time co-ordinate, of an ion peak in a mass spectrum, consists of fitting a suitable function, which is a superposition of bell-shaped curves, to all peaks of a peak group simultaneously instead of using only one isolated mass peak, and preferably applying a suitable abundance distribution for all the peaks of the measured group, e.g. of an isotopic pattern. The true mass distances between the individual peaks of the peak group and the ratio of their widths are usually known. The distances between the peaks of an isotopic pattern can, for instance, be derived in a good approximation from mean compositions of the substances of a chemical class. During curve fitting by a mathematical optimisation process, e.g. minimising the sum of the squares of all deviations, in the simplest case only the position co-ordinate and the width of the bell-shaped curves are varied. If the pattern used is an isotopic pattern, a precise position determination of the monoisotopic ions of the isotope group is obtained automatically, even if the monoisotopic peak is not visible at all. For organic substances, in the simplest case only the pattern of the carbon isotopes in that chemical class are used for pattern fitting.

Title: Minimising inter-machine data transfers in a distributed transaction processing system
Inventor: CHESSELL AMANDA ELIZABETH
IPC: H04L29/06
Filed: 1999-02-18
Abstract: A method of operating a first server 31 for use in coordinating a distributed transaction which is carried out by a plurality of servers is disclosed, the method having steps of: receiving a registration request from a second server 32; determining the machine address of the second server; keeping a list of the machine addresses of servers that send registration requests to the first server; determining the destination machine address of an outbound transactional request; determining whether that address is included in the list; and when it is included substituting for an identifier in the outbound transactional request identifying a transaction coordinator 311 located on the first server an identifier identifying a transaction coordinator, such as 3211, located on the server having the destination machine address of the outbound transactional request. This enables coordinator 3211 to aggregate the data flows of transactional requests of itself and other coordinators 3221, 3231 on the same server so that those other coordinators do not need to communicate directly with coordinator 311, thereby minimising the number of inter-machine data transfers.
Patent GB-2337391-A (GB)
Title: Interlaced to progressive scanning conversion with edge enhancement by vertical temporal interpolation
Inventor: WANG ZHONGDE
IPC: H04N5/44
Filed: 1999-03-17
Abstract: De-interlacing of video signals is achieved using vertical temporal interpolation to generate the missing lines of video from a weighted average of neighbouring lines from both the current and the adjacent fields. Using appropriate interpolation weighting coefficients, a desired frequency response is produced. The weighting coefficients are chosen such that the combined contribution from all fields is unity while the total contribution from each individual field is chosen so as to boost higher temporal frequencies. This has the perceived effect of increasing the sharpness of moving edges. The total contribution from the neighbouring fields is chosen to be negative. In order to avoid unwanted artefacts, the lines of the current video field are modified using a vertical temporal filter with similar temporal boosting properties to that used to generate the missing lines.

Title: Use of multi-symbol keys in an electronic programme guide
Inventor: ROBARTS JAMES O
IPC: H04N7/16
Filed: 1998-03-17
Abstract: An electronic programme guide (EPG) presents programming information to the viewer and allows for the composition of queries for searching the information. Queries relating to channel number, network name or programme name may be entered using a 10-key keypad. The viewer sequentially enters digits or letters in the number or name and the EPG interprets the data as representing all possible choices which include the numbers and letters associated with the sequence of selected keys. For example, when the key labelled "5" is selected, the EPG interprets that data to mean "5" or "J" or "K" or "L". The EPG identifies all programmes, channels or networks which begin with the number or letters, and as the viewer enters further data the list narrows so that the viewer is quickly presented with a short list of possible choices.
