Abstract

A method of forming a shaped article wherein said article comprises at least two parts which are chemically bonded, the method comprising: assembling at least two non chemically bonded parts in a weld cavity of a tool to form an assembly of the at least two parts, wherein said weld cavity is adapted to receive the assembly of at least two parts in the form of the shaped article; sealing the weld cavity of the tool; melting the assembly of at least two parts to chemically bond the at least two parts together to form the shaped article, wherein the shape of the weld cavity is matched to the outer circumference of the assembly of parts such that thermal expansion forces the polymer parts against the weld cavity surface and the pressure leads to full surface bonds between all parts, and wherein the tool forming the weld cavity comprises two halves forming a piston which fits into the bore of a bolster component and the plane of the split line between the two piston halves is parallel to the axis of the bore such that the pressure from the thermal expansion of the assembly of parts within the weld cavity is opposed by the surface of the bore preventing the weld cavity split line from opening and therefore preventing leakage of polymer from within the pressurised weld cavity volume, and wherein the two piston components are made from a dissimilar metal with higher coefficient of thermal expansion than the bolster component ensuring that at the welding temperature the piston is larger in diameter than the bore diameter of the bolster component leading to an interference fit which makes forces the weld cavity split line to close at the weld temperature but which still allows for a clearance gap between piston and bore at room temperature for the tool to be assembled and disassembled.

Abstract

A capacitive-resistive imaging system for imaging an environment comprises a plurality of conductive electrodes supported on a substrate, and have a side directed away from the substrate, wherein the conductive electrodes are, in use, galvanically isolated from the environment to be imaged, and capacitively couple thereto, and have a dielectric coating on at least the side directed away from the substrate. The dielectric coating advantageously is higher than 6, and more advantageously is much greater than 6. This encourages an electric field induced into the environment from the electrodes to penetrate further into the environment, and reduces coupling to the substrate. The invention has application in down-hole imaging, monitoring of constructions, foundations, and elsewhere.

Abstract

A non-systematic convolutional decoder of a convolutionally encoded multi-level data stream includes a shift register and two or more paths of exclusive-OR (XOR) gates, arranged to reconstruct an original input information stream, each path having a quantiser arranged to quantise the signal to two levels, and a set of XOR gates arranged to match an encoding path in an associated convolutional encoder, and a selector arranged to feed an output from each path to a single input of the shift register. If the paths have differing values at their output, the selector may choose the value from the path based upon a function of the multi-level signals associated with each path, such as the path with the largest absolute signal level. The decoder provides a simple means for decoding signals while allowing the signal to also or instead be decoded using e.g. a Viterbi decoder if higher performance is required.

Abstract

A method of forming a shaped article wherein said article comprises at least two parts which are chemically bonded, the method comprising: assembling at least two non chemically bonded parts in a weld cavity of a tool to form an assembly of the at least two parts, wherein said weld cavity is adapted to receive the assembly of at least two parts in the form of the shaped article; sealing the weld cavity of the tool; melting the assembly of at least two parts to chemically bond the at least two parts together to form the shaped article, wherein the shape of the weld cavity is matched to the outer circumference of the assembly of parts such that thermal expansion forces the polymer parts against the weld cavity surface and the pressure leads to full surface bonds between all parts, and wherein the tool forming the weld cavity comprises two halves forming a piston which fits into the bore of a bolster component and the plane of the split line between the two piston halves is parallel to the axis of the bore such that the pressure from the thermal expansion of the assembly of parts within the weld cavity is opposed by the surface of the bore preventing the weld cavity split line from opening and therefore preventing leakage of polymer from within the pressurised weld cavity volume, and wherein the two piston components are made from a dissimilar metal with higher coefficient of thermal expansion than the bolster component ensuring that at the welding temperature the piston is larger in diameter than the bore diameter of the bolster component leading to an interference fit which makes forces the weld cavity split line to close at the weld temperature but which still allows for a clearance gap between piston and bore at room temperature for the tool to be assembled and disassembled.

Abstract

A transmitter and/or receiver of the invention comprises of a system for encoding or decoding respectively an authentication signal comprising of an open CDMA signal in which a portion of the chips forming it are replaced with chips at cryptographically derived positions in the CDMA sequence. Thus, a suitably authorised receiver receiving such an encoded authorisation signal, and adapted to decode the cryptographically derived positions is able to generate a correlation with its own internal modified reference signal that proves the identity of the transmitted signal, whilst unauthorised receiver is able to correlate any unmodified chips with its open internal reference. The proportion of chips altered is preferably chosen to allow an unauthenticated receiver to successfully recover the receive signal. An authorised receiver may be adapted to correlate using both a modified reference code, and an open reference code, and compare the results.

Abstract

A non-systematic convolutional decoder of a convolutionally encoded multi-level (levels >2) data stream comprises a shift register and two or more paths of exclusive-OR (XOR) gates, arranged to reconstruct an original input information stream, each path having a quantiser arranged to quantise the signal to two levels, and a set of XOR gates arranged to match an encoding path in an associated convolutional encoder, and a selector arranged to feed an output from each path to a single input of the shift register. If the paths have differing values at their output, the selector may choose the value from the path based upon a function of the multi-level signals associated with each path, such as the path with the largest absolute signal level. The decoder provides a simple means for decoding signals while allowing the signal to also or instead be decoded using e.g. a Viterbi decoder if higher performance is required.

Abstract

A wind turbine including a support structure and one or more turbine blades is presented, that incorporates ways for reducing the radar cross section (RCS), wherein the support structure is notionally divided into an upper section in the shadow of the blade sweep area, and a lower section beneath the upper section, wherein the upper section is adapted to have the ways for reducing the RCS, and the lower section does not have the adaptation. The invention makes use of the realisation that the blade masking the tower as it rotates (or the blade being masked by the tower if facing away from a radar), contributes significantly to interference to radar systems, and so localised application of e.g. RAM can give good RCS reduction at a lower cost than treating the whole structure.

Abstract

The disclosed radio receiver comprises a downconverter for downconverting dual sideband signals such as Binary Offset Carrier (BOC)signals from multiple sources to produce an upper and a lower sideband signal, and chip-matched filters for filtering each of the sideband signals. The output of each filter is provided to a series of separate channels, one for each source, where there are at least Early, Prompt and Late gates. Each gate has a nearest-neighbour sampler and a multiplier for multiplying with an appropriate part of a spreading code, a mixer for removing Doppler or other frequency offsets and an integrator. The invention provides a means for demodulating signals such as BOC modulated satellite navigation signals in an efficient manner by using a single downconverter for the received signals of interest from the multiple sources.

Abstract

A code division multiaccess (CDMA) communications system with low probability of intercept, low probability of detect (LPI/LPD) includes at least one data dictionary stored on a storage device of a sender subsystem and a recipient subsystem. The at least one data dictionary includes at least one data predetermined start time and date, at least one data predetermined end time and date based on a mission length or a predetermined wrap time and date, a CDMA chip rate, and a complex zero-mean independent and identically distributed (iid) sequence where each complex number in the complex zero-mean iid sequence represents a CDMA chip stored on the storage device of the sender subsystem and the recipient subsystem. The system includes a tangible, non-transitory, machine-readable medium comprising machine-executable instructions which, when executed by at least one processor of a machine, cause the at least one processor to: receive a message, convert the message to symbols with corresponding phasors, determine a date and time to send the message, look up a data spreading vector for each corresponding phasor by providing a mutually agreed number of chips per phasor stored on the storage device of the sender subsystem and the recipient subsystem and by matching the date and time the message is to be sent to the at least one data predetermined start time and date and the at least one data predetermined end time and date. Each data spreading vector is multiplied by its corresponding phasor to create a data spread vector for each data spreading vector. The sender subsystem is configured to sequentially transmit each chip of each data spread vector as a signal.

Abstract

A drone detection radar can include a plurality of antenna systems, each antenna system being arranged to transmit a signal into an associated sector, and to receive signals reflected from targets in the sector, the sectors collectively forming a monitored volume, and wherein a sub-set of the antenna systems are active at any one time, with the active sub-set of antenna systems being arranged to monitor their respective volumes for a duration sufficient to measure Doppler signals associated with slow moving drones, with the radar being arranged to switch to a different sub-set of antenna systems after each duration, such that the whole volume is monitored within a predetermined period. Combining a staring array from an antenna system with a plurality of switched antenna system allows drones to be both detected and tracked, with appropriate selection of the predetermined period.

Abstract

A method for the reception of a frequency hopped direct sequence spread spectrum signal includes acquiring the signal by splitting the received signal into a plurality of processing sub-channels, each corresponding to one or more hop frequencies; and within each sub-channel: i) subtracting any sub-carrier frequency from the received signal; ii) filtering the signal from (i) using a chip-matched filter; iii) selecting a sub-set of samples from the filtered signal; iv) correlating the sampled signal from step (iii) with a known reference signal to produce at least one correlator output. The output(s) from each sub-channel are provided to an input of a corresponding one or more common discrete time Fourier transforms (DTFT), and an output therefrom having a peak above a predetermined threshold is selected for further processing in the receiver. The method is a less expensive way of tracking the signal and can demodulate appropriately modulated signals.
