Title: Multi-channel multiplexed communications
Inventor: TOMOFUJI HIROAKI
IPC: H04B10/293
Filed: 1996-01-19
Abstract: Each channel (eg of a TDM or WDM system) is sent to a corresponding electro-optical converter 10, each of which is monitored 11 and controlled 12 to produce a signal of suitable amplitude. Also, all the monitored outputs are processed 13 to provide 14 a further control signal (which depends, inter alia , on the number of converters in use) for all the converters 10. The outputs of the converters are combined 5 and amplified 6. The further control signal is also sent to the multi-channel amplifier 6 and subsequent repeaters. The repeaters (figs 11, 13, 14, 16) are of similar construction to amplifier 6 and operate in a similar way to the transmitter. This allows for problems induced by having a variable number of channels in use, and the relatively slow start-up of any newly activated channel, to be reduced.

Patent GB-2304306-A (GB)
Title: Work piece repair
Inventor: ABELA STUART ERNEST
IPC: E21B17/10
Filed: 1995-05-26
Abstract: A method of repairing a worn surface of a work piece especially but not exclusively a fin surface (2) of a down hole stabiliser tool (1) basically comprising placing an array of hard wearing trapezoids (10) e.g. of tungsten on the surface to be repaired and occupying the space between the trapezoids (10) by a filling (11) applied by a relatively low temperature fusion welding process, preferably using a MAG welding technique. The welding temperature, for example less than 250{C, can be well below the tempering temperature of the treated material e.g. steel, and this avoids harmful effects to the steel material. The worn surface can be dressed as a preliminary if necessary before the repair treatment proper. Additional layers are possible in the form of (a) matrix (12) and (b) an initial buffer layer (8) between the filling (11) and the treated surface, the latter (b) again being applied by low temperature fusion welding but the former (a) can be applied by brazing. It is beneficial for the trapezoids (10) to be arranged inclined relative to an axial direction of the surface being repaired. The present repair method is usable both for magnetic and non magnetic steels.

Title: Bitline level insensitive sense amplifier
Inventor: KHIEU CONG Q
IPC: G11C11/419
Filed: 1995-11-16
Abstract: A sense amplifier (221) for detecting the difference in voltage between two bitlines (113, 115) of a momory circuit. The sense amplifier is comprised of a differential amplifier (201, 203) which is coupled to the two bitlines (113, 115) and generates an output signal based on voltage levels sensed in the bitlines (113, 115). The differential amplifier (201, 203) is coupled to Vcc and ground through an active load (205, 207) and a current source (209) respectively. To address the problem of increased common mode voltage levels found in the bitlines (113, 115), a pair of transistors (223, 225) are connected in parallel across the active load (205, 207) to Vcc and the differential amplifier (202, 203). The gate of one of the transistors is coupled to one of the bitlines (113, 115) and the gate of the other one of the transistors is coupled to the other one of the bitlines (113, 115). With these two transistors (223, 225) coupled in parallel across the load (205, 207) as described, the differential amplifier (201, 203) has increased immunity to elevated common mode levels found in the bitlines (113, 115).

Title: A compressed data service in DECT/GSM interworking
Inventor: SIPILA TIMO
IPC: H04W28/06
Filed: 1997-10-10
Abstract: In a communications link between a DECT portable part 8 and a GSM mobile switching centre (MSC) 10, a compressed data service is provided. One of the DECT portable part or MSC sends to the DECT fixed part 9 a first message specifying a form of compression for data service. The DECT fixed part then sends a second message to the other of the DECT portable part or MSC requesting it to adopt a corresponding form of compression. If the requested form of compression is not acceptable then a message is sent back to the DECT fixed part specifying another form of compression. In this way the fixed part establishes a form of data compression that extends from end to end between the DECT portable part and MSC. Compressed user data can then be transmitted with decompression occurring at either end rather than at the DECT fixed part. If compression cannot be established end to end then compression is used on only part of the link, or different forms of compression used between fixed part and portable part and between fixed part and MSC. New compression parameters can be negotiated even in the middle of an established connection.

Title: Job Aiding Apparatus for Assembly Line
Inventor: NITTA MASAO
IPC: G05B19/418
Filed: 1998-07-10
Abstract: A display unit of a job aiding apparatus disposed at each work station of an assembly line, Fig.1 (not shown) provides images for showing a job detail in each of the work stations. The worker in each of the work stations performs the job according to the displayed job detail, step S1. The job aiding apparatus decides, steps S4, S12, whether a job result, S3, S11 falls within a predetermined range or not, and changes the job aid image to a next job aid image S7 only when the job result falls within the predetermined range. The worker is thus prompted to perform the job accurately and efficiently. For example, a torque setting S11 can be entered; in assembly lines where alternative components can customise the product, the correct choice of component can be verified by inserting a serial number, steps S3, S4.

Title: Influencing flow separation with vibrations from a passive resonator cavity
Inventor: GROSCHE FRITZ-REINHARD
IPC: B64C21/02
Filed: 1998-08-07
Abstract: A device serves for influencing the separation of a flow 2 from a body 1 immersed in the flow. The device excites a shear layer 11 of the flow 2 at the immersed body 1 by periodic blowing and suction in order to act against further separation of the shear layer 11 from the immersed body 1. For this purpose, the device has at least one passive cavity resonator 4,5,6, the cavity 4 of which has at least one opening 6 leading to the surface 10 of the body 1. The cavity resonator 4,5,6 is excited by the flow 2 thus creating compressional vibrations, and the compressional vibrations of the cavity resonator 4 to 6 excite the shear layer 11. The cavity 4 may have more than one opening (6' and ", fig 4). The position of the opening 6 relative to the point on the surface where flow separation may otherwise start is discussed.

Title: Emergency services warning system
Inventor: SCOTT MALCOLM GEORGE
IPC: G08G1/087
Filed: 1998-11-06
Abstract: The invention alerts the driver of a vehicle, via the in-car entertainment centre, to the presence of an Emergency Services Vehicle. This occurs via the Emergency Services Vehicle transmitting a signal, activated when the conventional siren is switched on, which would interrupt the radio signal and sound a warning through the entertainment system. The entertainment system would be interrupted whatever form of entertainment medium was being used. A receiver installed in every Traffic Management System (Traffic Lights, etc.) would allow the system to be alerted to the close proximity of an Emergency Services Vehicle. The Traffic Management System would override the sequence of the traffic lights etc., resulting in the traffic and the general public's flow being managed through the conventional means. The installation of an inhibitor to the Traffic Management System would prevent unauthorised use of the system.
