Abstract

Disclosed techniques relate to fragment launching. In an example, a fragment launcher has a casing, a launch aperture and a detonation position. An inner profile of the casing tapers from the main body towards the fragment launch aperture and from the main body to the detonation position. A fragment is held within the launch aperture such that when in use an explosive charge can be initiated to launch the fragment from the launcher. The launcher is particularly suited to uses where there is a requirement to launch a fragment in a consistent and repeatable manner.

Abstract

An aerial reconnaissance drone having a dragonfly format (elongate fuselage and flapping wings) with two cameras having respective diagonal fields of view, arranged at respective ends of the fuselage, both pointing forwards, wherein the second camera has a diagonal fielder of view that is at most half that of the first camera. This has the advantage of providing a drone that can capture enhanced imagery when required, by performing a half turn and switching which camera is being used. Since this avoids placing two cameras in the same location both can have a clear view of surroundings yet it helps avoid off balance caused by placing too much mass in any particular off-centre location.

Abstract

A computer implemented method of decoding a signal. The method includes receiving a signal (which may be an electromagnetic signal), sampling the received signal to generate an input waveform having magnitude and phase components, applying a transform operation to the input waveform to generate a first decoded signal, and outputting the first decoded signal. The transform operation includes pre-processing the input waveform to generate a mirrored inverted waveform and applying a continuous wavelet transform to the mirrored inverted waveform to generate the first decoded signal. This allows inversion of the frequency and temporal resolution of the continuous wavelet transform, thereby enabling improved temporal and frequency decoding of a signal. The method is particularly suitable for signal filters and filtering units.

Abstract

A method, computer system and computer-readable medium for determining a surface pattern for a target object using an evolutionary algorithm such as a genetic algorithm, a parameterized texture-generating function, a 3D renderer for rendering images of a 3D model of the target object with a texture obtained from the parameterized texture generating function, and an object recognition model to process the images and predict whether or not the image contains an object of the target object's type or category. Sets of parameters are generated using the evolutionary algorithm and the accuracy of the object recognition model's prediction of the images with the 3D model textured according to each set of parameters is used to determine a fitness score, by which sets of parameters are scored for the purpose of obtaining future further generations of sets of parameters, such as by genetic algorithm operations such as mutation and crossover operations. The surface pattern is obtained based on the images of the 3D model rendered with a surface texture generated according to a high-scoring set of parameters.

Abstract

A computer implemented method (70) of un-mixing mixed spectrum data of a physical location received from a spectroscopic measurement device (71). A spatial image of the physical location is received and segmented into a plurality of segments (72). A plurality of sets of endmember spectra are generated with each set comprising an endmember spectrum assigned to each of the segments of the spatial image (73). Abundance optimisation operations are performed (74) to generate abundance values for each endmember spectrum that optimise a cost function (75), thereby generating modelled spectrums. The modelled spectrum that optimises the cost function is output as the unmixed spectrum (78). The cost function (75) comprises a spectral similarity term (76) quantifying a difference between the mixed spectrum data and the respective modelled spectrum, and a structural similarity term (77) quantifying a difference between the spatial image and respective modelled spectrum. Using both terms ensures the un-mixed spectrum more accurately reflects the physical attributes of the physical location from which the mixed spectrum was observed. Particularly suited to the field of hyperspectral imagery.

The constellation spectrum is converted 38 to a time domain constellation signal which can be injected (33) into a CDMA receiver under test. The method allows for fast and cost-effective synthetic generation of constellation signals that are particularly suited to testing global navigation satellite system (GNSS) receivers. Also relates to apparatus for providing the same.

Abstract

A method, computer system and computer-readable medium for determining a surface pattern for a target object using an evolutionary algorithm such as a genetic algorithm, a parameterized texture-generating function, a 3D renderer for rendering images of a 3D model of the target object with a texture obtained from the parameterized texture generating function, and an object recognition model to process the images and predict whether or not the image contains an object of the target object's type or category. Sets of parameters are generated using the evolutionary algorithm and the accuracy of the object recognition model's prediction of the images with the 3D model textured according to each set of parameters is used to determine a fitness score, by which sets of parameters are scored for the purpose of obtaining future further generations of sets of parameters, such as by genetic algorithm operations such as mutation and crossover operations. The surface pattern is obtained based on the images of the 3D model rendered with a surface texture generated according to a high-scoring set of parameters.

Abstract

Apparatus is provided, and method of communicating between drones. Two drones are provided, a remote drone able to perform predetermined stored gestures and a local drone having a sensor to detect such gestures (e.g. a camera) and determine whether the movement comprises the predetermined gestures. If the performed gestures match the stored gestures the remote drone is authenticated. A drone may have both sets of functionality to enable two-way handshake protocol. Once the handshake protocol has been completed, transmission of further data is also possible. Movement gestures may include pseudo-random movements such as North, South, West, East, Up Down, and may have varying duration or delays between them. Since not all gestures will be visible to the receiving drone a statistical test is applied to determine whether there is a sufficient match to the predetermined code. The advantage is that a drone may authenticate and potentially share data with another drone, where transmissions are undesirable.

Abstract

A method (10) of regenerating a signal is provided. The method involves sampling (13) a received signal to obtain a plurality of samples each having an associated magnitude. The samples are sorted (15) to obtain a statistical distribution (which may be a histogram). Known distributions are fitted to the statistical distribution using a fitting operation (16, 17), and for each a measure of similarity is obtained. A matched distribution is then determined from the measures of similarity (18), that is subsequently used to regenerate a signal (12) that itself is statistically representative of the originally sampled signal. Such a method mitigates the storage burden associated with the recording and subsequent regeneration of representative wireless signal environments for wireless device testing. Also relates to an apparatus for the same.

Abstract

e.ge.g. iris) and an optical limiter device. The optical limiter comprises two layers (6, 7) of non-linear optical limiter material, and at least the one closest to the image sensor (5) has a front surface that is vulnerable to high intensity light, such that in a maximum-aperture size (lowest f number) situation if an incoming laser pulse was sufficiently intense to otherwise damage the image sensor, then this would instead cause blackening and/or distortion to that location on that front surface of the optical limiter material, thereby offering enhanced protection to the image sensor. Whilst the blackened and/or distorted patch that is formed leads to a dark spot on the resulting images and this persists afterwards, it has been found that this can be partially addressed using software and is far preferable to the image sensor not working.
