Abstract

A method and system is provided for processing audio information in a digital signal processor, where the audio information is either received from a microphone array or applied to a loudspeaker array. The digital signal processor applies a double delay-and-subtract beamforming algorithm to two non-collinear pairs of microphone outputs or loudspeaker inputs to provide an array with improved directionality and more uniform signal rejection away from the main beam of the beam formed signal. This can be further improved by tessellating multiple arrays into a macro-array and superimposing their responses.

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.

Abstract

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.

Digital input images of physical objects or environments to which the method is applied can then be used in image fusion, ortho-rectification or change detection applications, in order to monitor the physical object or environment.

Abstract

A body-wearable antenna system is described that comprises at least two antenna elements (2, 4) arranged to be mountable in a substantially equi-spaced distributed array around a user's body. Each antenna element is a directional type antenna and the antenna system is configurable such that when worn the antenna elements operate in phase to deliver a combined, higher gain, omnidirectional performance radiating away from the user's body, compared to one or more conventional body-worn omnidirectional antennas.

Each PIFA may feature at least one slot cut into the radiating top plate or at least one parasitic radiator, or a combination of both, to allow operation within distinct frequency bands and with predetermined impedance bandwidth.
