Title: In-band tone generation for a data transmission system
Inventor: EPWORTH RICHARD EDWARD
IPC: H04B10/564
Filed: 1990-08-24
Abstract: An in-band tone is superimposed upon a data stream for monitoring purposes, particularly for controlling the biasing of an injection laser (1). The tone is generated using a phase-locked oscillator (4) so that it shall be in phase quadrature with any spectral component of the data stream at that frequency. For injection laser bias control purposes a proportion of the light of the laser is intercepted by a monitor photodiode (5) and fed to a phase sensitive detector (11) supplied with a reference signal from the phase-locked oscillator, to provide a bias current feedback control signal. <IMAGE>

Title: Radial change multigear,comprising gear which is radially movable relative to a recessed disc
Inventor: SMITH SYDNEY
IPC: F16H3/36
Filed: 1992-01-11
Abstract: This gear system can consist of one or two hard metal discs into which shaped recesses have been cut at chordal intervals (each equal in length) to form circles at suitably chosen radii, into which a moveable cogwheel or pinion may be engaged by a radially sliding selector mechanism when the disc is stationary at certain points of recess alignment called Prime Radii, thus providing a selection of speed and torque ratios to the drive. A combination of disc gears will provide a simple shaft drive system for turning a drilling machine, or the propelling of a pedal cycle, make provision for a greater range of gear changes, (relative speed and torque ratios,) and the turning motion will be transferred from the recessed disc turned by the pedals to a cogwheel fined to a square or splined shaft which carries the motion to a similar cogwheel at the other end of the shaft which in turn is engaged with a recessed disc fined to the rear wheel which drives the bicycle along. On a bicycle then, the chainwheel, chain and the rear wheel sprocket will be replaced by a multispeed disc drive, to a cog driven shaft to a cog driving a multi speed disc at the rear wheel. <IMAGE>

Title: Monitoring battery parameters
Inventor: SYRJAELAE MARKKU
IPC: G01R31/36
Filed: 1992-09-29
Abstract: A battery (1) has identification means for enabling an apparatus e.g. a radio telephone or a battery charger, connected to the battery to determine a plurality of battery parameters e.g. temperature and battery capacity using a single measurement, so that, for example, a battery charger can adopt the correct charging regime for the battery type. The identification means is provided by a constant current source (l) and one or more solid state components (D1-D3) having p-n junctions e.g. diodes or transistors coupled in series or in parallel. As the threshold voltage (VD) of p-n junctions vary with temperature, and the number of components can be made to vary with battery type, by measuring the total voltage drop (Vo) across series connected components or current through parallel connected components which will vary with temperature and the number of components, a single signal can provide information on more than one battery parameter. In response to the signal Vo produced, a processor 2 operating with a looking table in a memory 3 provides an appropriate signal to a control circuit 4 which controls a device 5 e.g. a battery charger. The element 2 - 4 may be included within a radio telephone, the battery 1 or within the the housing of the charger 5. <IMAGE>

Title: Measuring gas and water content in oil using coil resonators
Inventor: HARPER RICHARD
IPC: G01N22/00
Filed: 1992-10-15
Abstract: The relative proportions of oil, water and gas in a mixture are determined by passing the mixture, in a dielectric pipe 5, through the coils of a number of coil resonators 1 having different resonant frequencies. By measuring changes in the resonant frequencies of the coil resonators the proportions of oil, water and gas can be calculated. Each coil is located in a conductive metal cavity 2 into which RF or microwave power is input through coaxial probe 3 and from which an output is sensed by coaxial probe 4. Preferably the coil resonators are arranged in groups, the resonators of each group having the same resonant frequency and each group having a different resonant frequency. In each group, the coil 1 is of larger radius than offset from the pipe 5 and the direction of offset is different for each member of the group. Preferably sixteen resonators, in two groups of eight, are used. The power input probe 3 is fed from a variable frequency source. <IMAGE>

Patent GB-924744-A (GB)
Abstract: 924,744. Gyroscopic apparatus. ANSCHUTZ & CO. G.m.b.H. July 24, 1961 [Aug. 5, 1960], No. 26792/61. Class 97 (3). In a directional gyroscope in which the rotor rotates about an axis A within a casing 10 which is mounted by horizontal trunnions 11, 12, defining an axis B, within a vertical ring 13 pivoted by trunnions 14, 15 defining a vertical axis C in a frame 16 and in which a spirit level 19 detects movement of the rotor about axis B to control torque motor 17, 18, so as to process the rotor back into a given level, the axis A is maintained parallel to the earth's axis by mounting the level 19 on a platform 22 pivoted on trunnion 12, and so operating a setting motor 24, which may be a synchro-receiver, that a worm 23 engaging a worm-wheel 20 fixed to trunnion 12, makes the platform 22 and level 19 tilt in accordance with the latitude. Since the earth's rotation thus does not process the gyro, the torque motor 17, 18 is only operated infrequently and for short periods of time, and the azimuthal indication of axis A tends to wander less than when the axis A is maintained horizontal. A torque motor 25 may be provided on trunnion 11 to maintain the spin axis A aligned in the plane of the magnetic meridian. The frame 16 may be carried by a float or may form a second gimbal ring having a pair of opposite trunnions coaxial to a horizontal axis E.

Title: Dynamic channel assignment in a communication system
Inventor: BRUCKERT EUGENE J
IPC: H04L12/56
Filed: 1992-12-01
Abstract: A communication system dynamically assigns channels to a subscriber unit so as to, inter alia, mitigate the effects of co-channel interference in the system. The communication system has a plurality of base-stations (111, 112, 115, 118) receiving the transmission of a subscriber unit (120, 100, 121) desiring service. Upon receipt of the subscriber unit's transmission, each base-station determines a signal quality value, which it then reports to a system controller (210). The system controller determines the best signal quality value reported and assigns a channel to the base-station which reported the best signal quality value. The chosen base-station transmits to the subscriber unit on an assigned channel to establish communication. The assigned channel transmitted by the chosen base-station need not be associated with the channel the subscriber transmits on. In fact, either channel may be any one of the channels allocated for use by the communication system. <IMAGE>
