Title: Fibre optic transmission
Inventor: HIRST IAN JOHNSON
IPC: H04B10/29
Filed: 1996-06-11
Abstract: Methods of providing supervising signals to amplifiers of a fibre optic system are described. In the system, traffic signals are carried at one or more traffic signal carrier wavelengths and are amplified by the amplifiers so that they are maintained in strength. Supervisory signals are provided either at two different carrier wavelengths, or at a single carrier wavelength which is, although different from the traffic signal carrier wavelengths, such that the supervisory signal is maintained in strength by the same amplifiers. Supervisory information is provided on the supervisory signal by modulation at a frequency substantially lower than that of a traffic bit rate for detection by detectors located at the amplifiers. A fibre optic system is also described which is adapted to utilise this method.
Patent GB-2305818-A (GB)
Title: Diagnosis/control of machines
Inventor: MOTOYAMA TETSURO
IPC: H04M11/00
Filed: 1996-05-22
Abstract: A method and system for monitoring, controlling and diagnosing operation of a machine such as a business office machine, e.g. a facsimile machine (28), a copier (24) and/or a printer (32). When the speed of communication between the remote device (16, 18, 20, 22) and machine is not urgent, a connectionless mode of communication may be used. The preferred form of connectionless communication is an electronic mail message transmitted over the Internet. However, when a condition needs urgent action, a direct connection is used for communication such as communication via a telephone or a ISDN line. The information obtained from the machine is stored in one or more data bases within a company and information of the machine is shared between a service department, engineering and design department, manufacturing department, and marketing department. As communication over the Internet via electronic mail is not secure, the connectionless-mode messages transmitted using Internet electronic mail are encrypted.
Patent GB-2320127-A (GB)
Title: Display device
Inventor: KNOX ANDREW RAMSAY
IPC: G09G1/20
Filed: 1996-12-04
Abstract: A display device comprises a cathode 20 for emitting electrons and a permanent magnet 60. A two dimensional array of channels 70 extends between opposite poles of the magnet. The magnet 60 generates, in each channel 70, a magnetic field for forming electrons from the cathode 20 into an electron beam. A screen 90 receives an electron beam from each channel. The screen 90 has a phosphor coating 80 facing the side of the magnet remote from the cathode. The phosphor coating 80 comprises a plurality of pixels each corresponding to a different channel. A grid electrode 40 is disposed between the cathode and the magnet for controlling flow of electrons into each channel. Deflection means, e.g. anodes 50, sequentially addresses the electron beam from each channel to each pixel of the corresponding group. Rotational alignment means finely aligns electron beams from the channels with corresponding pixels of the phosphor coating. The rotational may be provided by making anodes 51,52 resistive and generating a differential voltage across them. The magnitude and direction of the differential voltage is used to provide rotational alignment. The invention also provides a method of coarse alignment of the magnet with phosphor stripes on the screen by providing a collimated light source, illuminating the phosphor stripes through channels in the magnet using the light source, and aligning the two dimensional array of channels with the phosphor stripes, either visually or automatically.

Title: Damping torque reversal jerkiness in an internal combustion engine
Inventor: FROEHLICH JOHANN
IPC: F02D11/10
Filed: 1998-03-26
Abstract: Undesirable jerking movements caused by torque reversals between the engine and transmission are damped by controlling the engine output in the region of zero torque to only allow repeated small changes rather than sudden big changes. An estimated desired torque TQ_REQ_ESTn is derived cyclically from accelerator pedal position and one or more other operating variables (steps S1, S2). If this estimate is different from setpoint torque TQ-REQ_SPn-1 calculated in the previous cycle (S3, S4), it is determined whether that setpoint torque is in a range close to zero (S7, 58). If so, a small change value AW is derived from a family of characteristics e.g. engine speed, transmission ratio, air/coolant temperatures (S11) and limits the new setpoint TQ_REQ_SPn relative to the previous one (S13, S14). In a second embodiment (Fig. 5 not shown), for changes outside the range, misfires and slow speed stalling are prevented by filtering the setpoints using a time constant dependent on speed.
