Abstract: A non-circularly-symmetric intensity distribution is formed on a quadrant photodetector by coherently mixing two optical signals propagating in selected modes of different order. These modes are chosen either such that a change in relative phase of the two signals produces solely a rotation of the orientation of that intensity distribution, or such that a change in relative states of polarization produces this rotation.

Abstract: An optically addressed optical fiber sensor system in which light is employed to excite an optical fiber cantilever (6) into mechanical oscillation at a frequency f.sub.o. This oscillation modulates the amplitude of the light launched into the cantilever. The sensed parameter controls the displacement of the free end of the cantilever with respect to the end of the fiber (2) from which light is launched into the cantilever. The magnitude of this displacement affects the magnitudes of the components of modulated light at frequencies f.sub.o and 2f.sub.o. From an analysis of these components a measure of the displacement is obtained, and also a measure of the magnitude of the sensed parameter.

Abstract: In a semi-custom integrated circuit, e.g. a bipolar analogue array, underpass areas are so configured as to permit operation as capacitors by suitable configuration of a user determined interconnection pattern. Typically each underpass comprises a highly doped region disposed over a buried layer. A thin oxide layer is applied to the surface of the underpass. Suitable configuration of polysilicon and metal masks provides either a cross-over or a capacitor.

Abstract: Encapsulated optical fibres (FIG. 1A), for e.g. a submarine cable have their encapsulation removed by high velocity hot air blowers (6,7), leave free the acrylate coated fibres for splicing/jointing. An automated equipment moves the blowers progressively along the fibres to free between 0.75 and two meters.

Abstract: An aerial optical fiber cable comprises a glass-fibre-reinforced plastics core member (1) having a slot (2) with a zero lay angle accommodating loose-tubed optical fibres (3, 3A) and sheathed with a longitudinal tape (13) bound with a binder (915) and over-sheathed with a plastics extrusion (14). The cable is self-supporting and completely non-metallic and is suitable for telecommunications and data transmission services alongside overhead power transmission systems. An alternative embodiment (FIG. 2) is not self-supporting but is similar in design and adapted for support from a support wire, and another embodiment has a rectangular slot housing one or more ribbon elements. The cable is simple and cheap to make.

Abstract: A sequential decorrelator arrangement for an adaptive antenna array comprising a plurality of antenna elements the outputs of which feed a cascaded beamforming network having a succession of stages, each stage having one less decorrelation cell than the preceding stage and the first stage having one less cell than the number of antenna elements.The network includes means for applying weighting to the signals applied as inputs to the cells of at least the first stage. The decorrelation cells in each stage comprise means for applying simple rotational transforms to the input data in accordance with a weighting factor common to all the cells in a stage, each stage further including means for deriving said weighting factor from the weighting factor deriving means of the previous stage and the output of one cell of the preceding stage. Each stage includes means for scaling the output of each cell in the stage by a scaling factor calculated from the weighting factor deriving means of the stage.
