Title: Determining sound velocity profile using an acoustic transmitter and acoustic receivers
Inventor: VIGEN ERIK
IPC: G01V1/38
Filed: 2006-04-26
Abstract: A sound velocity profile of a fluid (e.g. sea) is calculated by transmitting an acoustic signal (e.g. from a transmitter 1 on a vessel 3) having a vertical component through the fluid and receiving the signal at a plurality of receivers 2 along a cable (e.g. marine seismic streamer or seabed cable) 4 as it traverses vertically through the water column. The sound velocity profile is determined from the reception time of the acoustic signal at the receivers. Alternatively a sound velocity profile of the fluid may be calculated using a plurality of transmitters on a marine seismic cable and an ultra-short baseline receiver mounted on a vessel. Also, the signal may be a spread spectrum signal having an orthogonally coded signal sequence and the distance between receivers 2 can calculated from measured time differences between signal detection at each receiver 2 and the differences in arrival time between signals from different transmitters 1 at each receiver 2.

Title: Water pipe and water meter monitoring system
Inventor: GRAY DOUGLAS
IPC: F17D5/06
Filed: 2006-10-23
Abstract: A water pipe and water meter monitoring system comprises a length of exposed electrical conducting material (G) inside a length of water pipe (H), a 'volts free' magnetic reed relay switch (N), an earthing rod (O) and a monitoring unit (C). The system may be used to detect a leak of water from the pipe (H) by monitoring changes in earth loop electrical resistance when water leaks from the pipe and makes contact with the ground (M). The system may be used to provide remote water meter monitoring using the magnetic reed relay switch. The remote meter (I) has magnetic elements which move with the flow of water and which opens and closes the relay switch (N) which is connected to an electrical earth and provides earth loop electrical resistance variations which are monitored in unit (C). The system may also comprise an exposed electrical conducting material (G) with linear electrical resistance properties and a length of an electrically insulated electric conductor (E) inside the pipe (H) which are used to detect water leak location along the pipe. The earth loop resistance variations are monitored and the leak position is calculated from the resistance changes. The exposed electrical conducting surface (G) inside the pipe can also be used as a communications bearer for a variety of remote signalling applications.

Title: System and method for concurrent operation of multiple radar or active sonar systems on a common frequency
Inventor: PONSFORD ANTHONY M
IPC: G01S7/36
Filed: 2005-04-27
Abstract: A system and corresponding method for the concurrent operation of multiple radar systems on a common frequency and in the same geographical area includes a waveform generator that specifies certain operating parameters for the transmitted radar pulses. In a first instance, the carrier frequency can include an offset for each radar system. In a second instance, complementary codes can be used for the radar pulses such that each radar system operates with a unique code for substantially reducing the cross-talk between the radar systems. In another instance, both carrier frequency offset and complementary coded waveforms can be used to increase the number of radar systems that operate concurrently. Carrier frequency offset can also be used to combat range-wrap by using different carrier frequencies for adjacent radar pulses.

Title: Frequency-hopping method and mobile communication system
Inventor: ARNOTT ROBERT
IPC: H04B1/713
Filed: 2007-02-05
Abstract: The communications system comprises user devices which communicate with an associated base station. The user devices employ frequency hopping to provide frequency diversity in their communications with the base station. In the present technique, radio resources are divided into contiguous sub-bands each comprising N frequencies. An initial allocation of resources is made and subsequently a hopping sequence applied, each frequency shift of which is a whole number of sub-bands. Techniques are also described for reducing collisions between the communications from different user devices and for the efficient signalling of data defining the frequency hopping sequence to use. The inventions are particularly suitable for use in the uplink of the E-UTRA communications scheme.

Inventor: KARTHAUS UDO
IPC: H03M1/10
Filed: 2008-09-25
Abstract: An apparatus or method for calibrating a tuneable resonator of a delta sigma modulator of the continuous time, band pass type, comprising: driving the tuneable resonator output signal to oscillate at an oscillation frequency of the resonator; providing a reference signal from a source having a desired frequency; detecting a frequency deviation between the oscillation frequency and the desired frequency at a frequency detector; controlling the tuneable resonator in dependence on the frequency deviation signal so as to reduce frequency deviation.

The apparatus may comprise a frequency divider that receives the resonator output signal and provides a frequency divider that receives the resonator output signal and provides a frequency divided resonator signal to the frequency detector. Control of the tuneable resonator is achieved with a controller which may be configured to perform a successive approximation algorithm for determining a control signal to provide to the tuneable resonator. The apparatus may also comprise an oscillation detector that receives the resonator output signal and provides a signal to the controller, from which the controller determines a resonant driver command that adjusts the resonator driver to a setting close to the stability limit of the resonator.
