Abstract

A jet vectoring apparatus has a nozzle (1) which comprises a throat aperture (8) and an exit aperture (9), the apparatus also having a post exit surface (10). Variation of at least one of the throat aperture (8), exit aperture (9) and post exit surface causes a pressure differential upon the post exit surface which permits the direction of propulsive jet flow (3) (also known as jet thrust) to be varied relative to the longitudinal axis (2) of the apparatus.

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.

A computer implemented method of decoding a signal.

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 method for testing a receiver in a code division multiple access (CDMA) communications system. Frequency spectrums for each of a plurality of provided CDMA code patterns (31) are generated (35) and phase shifted (36), before being combined (37) to generate a constellation spectrum. 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 laser detector apparatus (1) is provided, where a pixel array (3) is arranged behind a lens arrangement (4) such that distant objects (9) (in general, those at infinity) are out of focus at the pixel array. The image from the pixel array is evaluated by a computer processor (6) to detect such out of focus images which will be of a known size and shape (generally circular spots of known width). This can enable distant laser threats to be readily distinguished from nearby bright objects (10), whilst also protecting the pixel array from powerful laser sources (because the laser energy is not focussed to a point, on the pixel array it is less likely to damage the pixel array). It can also enable the wavelength of the laser to be accurately determined from the ratio of colours in the image of the laser spot, because it will typically not be a saturated image. The apparatus and method are particularly suitable for identifying and distinguishing laser sources across a wide range of brightnesses, and is also suitable for detecting and distinguishing multiple laser sources.

Abstract

A collimator taking the form of a prolate spheroid (40) comprising radiation attenuating material and featuring a twisted slit comprising radiation transmissive material. The twisted slit featuring first (43) and second (44) apertures arranged such that for each entrance point in one of the apertures there is a direct pathway through the major axis ‘B’ of the prolate spheroid (40), at a pre-determined angle, to a point in the other aperture, such that a compound aperture is formed. For each compound aperture the length of the direct pathway through the prolate spheroid (40) is constant. Rotation of the collimator about the major axis ‘B’, relative to a stationary point at the first aperture (43), steers in angle the compound aperture through the collimator from said stationary point. Such an arrangement allows radiation from a source positioned at said point to be collimated into a beam, the resultant beam being scanned in angle, and the resultant collimation effect being constant across the angular range of the scan.
