Patent GB-2340334-A (GB)
Title: Automatic volume control according to ambient noise
Inventor: HURST JEFFREY
IPC: H04M1/60
Filed: 1998-07-29
Abstract: The volume of a loudspeaker in a telephone is automatically adjusted according to the ambient noise at the telephone location. During a predetermined time window which exists during the initial period of a telephone call, the ambient noise is measured, and the volume of the loudspeaker adjusted accordingly. For example, the time period may exist between the time when the telephone goes off-hook, until the time when the handset is placed near the ear. Adjusting the ambient noise during this period has the advantage of not having to filter out the user's speech, as would be the case when measuring the ambient noise while the user is speaking. Furthermore, there is no requirement for circuitry which detects gaps in speech.

Title: Acoustic measurement while drilling system using compressional waves reflected from within formation
Inventor: JEFFRYES BENJAMIN PETER
IPC: G01V1/44
Filed: 1998-12-30
Abstract: A method of seismic exploration while drilling from within a borehole containing fluid, with a source (which may be the drill bit 13) and receivers (15, fig 1), positioned in the borehole is disclosed. The method involves detecting compressional waves (D, T, TD, DD) which have originated directly from the source (primary waves) and using information provided by these to detect secondary waves (P, PP, PPT) which have been reflected from a discontinuity 23 within the surrounding formation 24. Signal processing techniques are used to create a predication filter to allow the elimination of background noise from the drilling and to find the signals which have been reflected from within the formation. The compressional waves are detected using a plurality of pressure sensors or ring hydrophones (15, fig 1) positioned so that an average signal can be received over the circumference of the borehole. The apparatus is preferably attached to a coiled tubing with the drill bit actuated by a separate actuator as source.
Patent GB-2347284-A (GB)
Title: Receivers
Inventor: NASH ADRIAN PHILIP
IPC: H03D3/00
Filed: 1999-02-22
Abstract: In a receiver, AC coupling 12, 13 used to remove unwanted DC at the output of a mixer 4 introduces a notch into the centre of the IF pass-band and the carrier term is removed. This is overcome by comparing at 83 the DC component in the demodulator 6 output with a non-zero reference signal from 81 to apply an offset control signal to the mixer oscillator 5 so that the carrier term occurs at this offset frequency and not within the DC notch. The signal received by the demodulator 6 may be an FM signal or an IQ data signal. A phase lock loop 9 enabling initial tuning of the oscillator 5 is disabled when the demodulator 6 output equals the offset value. The oscillator is thereafter controlled by an AFC loop. In a further embodiment (fig.2 not shown), the baseband signal at mixer 4 output is upconverted before being demodulated. The receiver may form part of a transceiver.
Patent GB-2347055-A (GB)
Title: Network connections
Inventor: BURGESS JON JAMESON
IPC: H04L12/413
Filed: 1999-04-01
Abstract: A network includes one or more passive communications hub 12 having a number of ports 12a, with the network being made up of connections to, and optionally interconnections between, the ports. The network is arranged to carry electrical signals of different frequencies and characteristics. In particular the network distributes DC signals substantially without attenuation, and oscillation signals substantially without reflection. In the preferred implementation, the network carries both TV signals and computer network signals, such as ethernet signals. In this context the carrying of DC signals substantially without attenuation, by way of a controlled DC resistance in the network, enables the proper functioning of ethernet collision detection.

Title: Optical packet router
Inventor: HALL TREVOR JAMES
IPC: H04L12/773
Filed: 1999-07-16
Abstract: A packet routing architecture consists of an input packet handler, a 'core' switch and an output packet handler. The input packet handler translates the incoming address format into a form suitable for the fast operation of the core switch and segments the packet to a length suited to the core switch. The core switch consists of three main parts; an input alignment part, an optical interconnect and an electrical fan-out. The optical interconnect may involve optical fan-out or a one-to-one array of connections. The output packet handler reconstitutes the packet into its original (incoming) format. The efficient operation of the electrical fan-in part is achieved by phasing the start of the incoming packets and the electrical fan-in part contains the storage means to provide the necessary queuing for outgoing packets. Features of this interest are the architecture as a whole, the method of phasing packets, the organisation of the electrical fan-in circuits, and the use of Sectorised Orthogonal transfer (SOT).
