摘要： A radar reflector comprises a pair of opposed colinear solid dielectric lens reflectors (10) and two corner reflectors (11) between to provide substantially uniform and high reflectivity in the plane of the reflector elements. Radar energy strikes the outer convex surface of a first converging lens element (12) of relatively high dielectric constant and is then transmitted through a second lens element (17) of material having a relatively lower dielectric constant to a reflecting metallic coating (18) on the outer convex surface of the second lens element (17). The surfaces of the two lens elements (13, 14, 18) are formed such that their respective radii of curvature decrease with distance from the axis of symmetry (15). The first lens (12) is preferably silica flour in a polyester resin with a dielectric constant substantially equal to 3.4 while the second lens element (17) is an expanded foam polystyrene with a dielectric constant substantially equal to 2. Preferably the corner reflectors (11) are trihedral reflectors.

摘要： A large area liquid crystal display comprises a layer of liquid crystal material between two cell walls. One cell wall has a common sheet electrode. The other cell walls comprise a plurality of addressing tiles electrically connected together. Driver circuits at the display edges apply addressing voltages. Each addressing tiles comprises a series of m data electrodes and n gate electrodes arranged to form an m x n matrix array of electrode intersections. At each intersection is a pixel patch electrode and a non linear element connected to adjacent source and gate electrodes and to the pixel electrode. The data and gate electrodes continue across the tile surface and around its edges. Adjacent tiles are electrically connected together by an anisotropic glue, or by solder bumps, or electrical bridges. The liquid crystal material may be encapsulated in a polymer matrix or be a non-encapsulated layer. Dyes may be incorporated in the liquid crystal material. The pixel electrode may be formed as a group of three independently addressed electrodes each providing a different colour so the display may be a multi-colour display.

摘要： A dynamical system analyser (10) incorporates a computer (22) to perform a singular value decomposition of a time series of signals from a nonlinear (possibly chaotic) dynamical system (14). Relatively low-noise singular vectors from the decomposition are loaded into a finite impulse response filter (34). The time series is formed into Takens' vectors each of which is projected onto each of the singular vectors by the filter (34). Each Takens' vector thereby provides the co-ordinates of a respective point on a trajectory of the system (14) in a phase space. A heuristic processor (44) is used to transform delayed co-ordinates by QR decomposition and least squares fitting so that they are fitted to non-delayed co-ordinates. The heuristic processor (44) generates a mathematical model to implement this transformation, which predicts future system states on the basis of respective current states. A trial system is employed to generate like co-ordinates for transformation in the heuristic processor (44). This produces estimates of the trial system's future states predicted from the comparison system's model. Alternatively, divergences between such estimates and actual behaviour may be obtained. As a further alternative, mathematical models derived by the analyser (10) from different dynamical systems may be compared.

摘要： Apparatus for the physical vapour deposition of an alloy whose constituent elements have widely differing vapour pressures comprises an inner evaporation crucible (1) surrounded by a second evaporation crucible (2) having an array of nozzles (9) angled towards collector (5). In use of the apparatus, a charge (3) of relatively low volatility is evaporated from inner crucible (1) using an electron beam (7) focussed by magnet (8). Charge (4) in second crucible (2) is of much higher volatility and is evaporated by radiant heating. The nozzles (9) direct the vapour from charge (4) along pathways which intersect the vapour rising from charge (3) such that the combined vapour stream reaching collector (5) is an intimate mixture of constituents. The nozzles (9) may also serve to control the flow rate of vapour from the second crucible (2).

摘要： A Double Barrier Resonant Tunnelling (DBRT) diode (44) within a mixer and capable of acting as a gain element within a circuit suitable for handling microwave and millimetre wave frequencies. The mixer is adapted to receive an oscillating input signal (R.F.), a local oscillator signal (L.O.) and a DC bias voltage (D.C. Bias) where the DBRT is biased either at, or near, the peak or valley of a Negative Differential Resistance (NDR) region and the amplitude of the local oscillator signal is sufficient for part of the local oscillator voltage cycle to be within the NDR region, then the DBRT operates in a fundamental mode. Typical optimum DC bias voltages for peak and valley voltages of 1 V and 1.5 V respectively are between O V and 2.0 V.

摘要： A digital processor for simulating operation of a parallel processing array incorporates digital processing units (P1 to P8) communicating data to one another via addresses in memories (M0 to M8) and registers (R11 to R41). Each processing unit (e.g. P1) is programmed to input data and execute a computation involving updating of a stored coefficient followed by data output. Each computation involves use of a respective set of data addresses for data input and output, and each processing unit (e.g. P1) is programmed with a list of such sets employed in succession by that unit. On reaching the end of its list, the processing unit (e.g. P1) repeats it. Each address set is associated with a conceptual internal cell location in the simulated array (10), and each list is associated with a respective sub-array of the simulated array (10). Data is input cyclically to the processor (40) via input/output ports (I/O5 to I/O8) of some of the processing units (P5 to P8). Each processing unit (e.g. P1) executes its list of address sets within a cycle at a rate of one address set per subcycle. At the end of its list, each of the processing units (P1 to P8) has executed the functions associated with a conceptual respective sub-array of simulated cells (12), and the processor (40) as a whole has simulated operation of one cycle of a systolic array (10). Repeating the address set lists with further processor input provides successive simulated array cycles.

摘要： Apparatus for producing refractory material filaments comprises an enclosure (11), means for heating the constituents of the refractory material, non-contacting means to support a drop (17) of molten material such as silicon, being one of the constituents of the refractory material within the enclosure and means to transport a filament (10) such as carbon, being a second constituent of the refractory material, through the drop of molten material in use. A levitation coil and/or an inert gas jet is used to support the drop of molten material and a silica glass or other refractory tube (13) is used to direct the gas jet. The enclosure has opposed side arms (15, 16) respectively for entry and exit of the filament (10) or the filament may be passed vertically through the molten silicon drop. An inclined side tube may be provided through which grains of silicon may be introduced into the enclosure for addition to the molten drop. In one form, initial heating of the silicon prior to levitation is achieved by providing a resistively heated silicon nitride platform on which the silicon is melted, the platform then being moved from the field of the levitation coil to leave a levitated silicon drop.

摘要： Intelligent signal processing circuits typically involve complex circuitry with large numbers of wire interconnections and tend to have high power requirements. An intelligent digital signal processing circuit is proposed which comprises: a) a digital signal processor (DSP); b) the interfacing of a plurality of serial data channels to the DSP with each channel being capable of converting a received analogue signal to a digital signal; c) a power supply for each channel where the power supply is modulated by a common clock signal and each channel possesses means to separate the clock signal from the power supply. For the purposes of data transmission wiring can be limited to 3 wires per channel, one for serial data, one for power and a timed pulse to synchronise data transmission and one as an earth return. Circuits produced according to the invention can handle multiple signals, real-time signal processing of incoming signals and the output of filtered signals in digitally multiplexed format.

摘要： Light from a laser (10) is divided by a beam splitter (12) to provide signal (15) and reference (14) channels. The signal channel light is expanded (11) to illuminate an acousto-optic (AO) device (13). This leads to a spatial distribution of Doppler shifted frequencies. This spatial distribution then illuminates a spatial light modulator (SLM) (19) such that a number of parallel and discrete optical channels (112) emerge. In a local area network (LAN) the optical signal channels are coupled into a single mode optical fibre (22) and then heterodyned to the reference laser light from a further optical fibre (23) in an optical coupler (25). In a receiver the modulated light is detected (32) and the detected signal connected to the transducer of an AO device (35). The AO device (35) is illuminated by a receiver laser light (36) and the emerging modulated light is incident on a focal plane detector array (39) where each detector (310) then receives light corresponding to each of the transmitted channels (311). A secure free space communications system is possible by separate transmission of a delayed (43) unmodulated reference signal. The receiver is then arranged to include an identical delay (55) in the signal channels before coupling together the signal and reference channels (56) for modulating the AO cell (35). By this means the transmission delay lines (43) and the reference delay lines (55) must have delays which are equal within the coherence length of the source laser.
