摘要： Methods and associated apparatus and programs for computers for operating geolocation devices are provided. The methods include determining the duration of a time interval during which the device is configured to remain active, responsive to a comparison between an estimate of benefit of remaining on for that time interval and an estimate of cost of remaining on for that time interval. The estimates of cost and benefit may be determined in response to user-selected parameters where by the end-user may effect a trade-off between battery life and receiver sensitivity. The methods also include varying the maximum duration of each listening period whereby to conserve battery power.

摘要： A method of processing a temporal sequence of base images from a synthetic aperture system such as a synthetic aperture radar is provided that simplifies the task of identifying moving objects. The method comprises the steps of firstly temporally filtering a plurality of the base images to form a reference image, and secondly normalising the reference image with a base image to form a change detection image. The change detection image has the property that all moving objects are emphasised. Further processing can optionally be performed on the change detection image to remove false targets based on characteristics of the highlighted areas or on a temporal track taken over a plurality of change detection images. The invention allows detection of moving objects without requiring a Doppler return from a target. The invention extends to a system adapted to implement the method, and a computer program.

摘要： The present invention relates to an imaging system which employs the same principles as coded aperture imaging. High angular resolution coded aperture imagers require a small aperture size and relatively large spacing between the coded aperture array and the detector. At such high resolutions diffraction effects can start to dominate and can degrade image quality. The present invention provides a detector array (8) which receives radiation from a scene (4) via a coded diffractive mask (6). The coded diffractive mask is designed such that its diffraction pattern at the waveband of interest is a well conditioned coded intensity pattern having a strong autocorrelation function with low sidelobes. Thus radiation reaching the detector array is diffracted by the diffractive mask (6) but in a defined way and it is the diffraction pattern of the mask which provides the coding. The scene image can then be reconstructed using the same techniques as for conventional coded aperture imaging but using the diffraction pattern of the mask as the aperture function. The coded diffractive mask may be a binary or greyscale mask, may operate in reflection or transmission and may be an amplitude or phase modulating mask.
摘要翻译：本发明涉及采用与编码孔径成像相同的原理的成像系统。高角度分辨率编码孔径成像器需要小的孔径尺寸和编码的孔径阵列和检测器之间相对较大的间距。在这种高分辨率下，衍射效应可以开始占主导地位并且可能降低图像质量。本发明提供了一种经由编码衍射掩模（6）从场景（4）接收辐射的检测器阵列（8）。编码的衍射掩模被设计成使得其在感兴趣的波段处的衍射图案是具有较强自相关函数且具有低旁瓣的良好调节的编码强度图案。因此，到达检测器阵列的辐射由衍射掩模（6）衍射，但是以限定的方式衍射，并且是提供编码的掩模的衍射图案。然后可以使用与常规编码孔径成像相同的技术来重建场景图像，但是使用掩模的衍射图案作为孔径函数。编码衍射掩模可以是二进制或灰度掩模，可以在反射或透射中操作，并且可以是幅度或相位调制掩模。

摘要： A multicore optical fibre includes a microstructured cladding material formed from a plurality of cladding elements (101) arranged in an array and each cladding element comprising at least two different materials each having different refractive indices, and a plurality of core elements (11) formed within interstitial regions (10) between adjacent cladding elements (101) . A fibre so formed may have a large number of cores per unit cross-sectional area as compared with prior art fibres, and thus allows the fibre to have relatively short distances between adjacent cores for a given required inter-core isolation. A fibre so formed has utility in many areas requiring high core density, such as inter-chip optical communication, or optical communication between circuit boards.
