Abstract: An electrical circuit arrangement includes a conductive link through an insulating layer separating two conductive layers. This link is formed by placing an evaporable plug on a first conductive layer, forming the insulating layer around it and then vapourising the plug. The resulting gap is then infilled with conductive material and a second conductive layer formed on the insulating layer.

Abstract: Compression of digitized pictorial data is achieved by comparing a data block of a predetermined size with a group of patterns relevant to that size held in a library. If a match is found the data block is represented by an output signal by a code identifying the pattern. If no match is found the data block is sub- divided into smaller blocks which are compared with another group of patterns. This sub-division process continues until the data is matched or a predetermined minimum size of data block is reached, when the data itself is applied to the output signal. The compressed data may be reconstituted and displayed or used to monitor the progress of a vehicle.

Abstract: In a method of driving a matrix of ferroelectric liquid crystal devices in a TDM mode, each strobing signal comprises first and second pulses (29, 21) of opposite polarities and of different amplitude, together with a dc voltage (26) which is applied from the end of the second pulse to the be­ ginning of the first pulse of the next strobing signal on the same strobe line to cancel the dc level which would be caused by the unequal pulses. Data ON signals applied selectively to data lines of the matrix comprise two consecutive pulses (22, 23) of opposite polarities. Data OFF signals (24, 25) may be the inverse of the data ON signals or may comprise a constant dc level. The combination of the two pulses with a dc level to form each strob­ ing signal means that only two strobe pulse time slots per frame are re­ quired for addressing each strobe line, as compared with the conventional systems in which four time slots per frame are required.

Abstract: A liquid crystal display comprises a body of a nematic liquid crystal host material (1) which contains a pleochroic fluorescent dye and which is supertwisted. Parameters of the display are selected such that the display has a transmission wavelength spectrum which encompasses the emission spectrum of the fluorescent dye. In a backlit mode, the display op­ erates in transmission and the light from an electroluminescent panel (11) excites the fluorescent dye in the liquid crystal. In high ambient light levels, the display operates in a reflective mode and the fluorescence is excited by ambient blue or ultraviolet light. The absorption and the fluorescence of the dye are anisotropic, so that switched segments appear dark. In unswitched regions of the display, however, the fluorescence is excited and gives a bright background to the display. Hence, the effect of the fluorophor is to improve the brightness of the display.

Abstract: In a synthetic aperture radar system the radar pulse echo return signals are sampled, which samples are correlated with a replica of the original signal to produce range line samples with increased resolution in the range direction. To increase resolution in the azimuth direction, a series of range lines are correlated or combined in some other way with Doppler or other reference coefficients.
A problem with this is that there is relative movement between any particular point on the ground and the radar system, and the samples in the range lines corresponding to that position lie on a slant line such as 103 (skew axis y). To utilise the incoming data, the skew axis is arranged in a saw-tooth form. To facilitat processing data is fed into an input sequence of data storage location in for example a buffer 51, at a variable starting position which moves corresponding to each discontinuity in the zig-zag, so that the discontinuities are transparent to the processor. In one embodiment, azimuth processing can take place along columns in bands 83 in a two-dimensional memory 53 corresponding to swaths on the ground 101.

Abstract: In a method and apparatus for the location and recognition of a simple (e.g. polyhedral) object (2), relative movement between the object and a video camera (1) is achieved by scanning of the camera or movement of the object. The object is surveyed by the camera, and pixels representing at least three successive images (3) generated by the camera are stored. The pixels are processed to locate edge-representing pixels (edgels). Visual motion vectors are computed at the edgels in the central one of the three images. The edgels are notionally linked into strings (18-36) representing edges of the object interconnected at vertices (12-17), to form a vertex-edge graph, which is subsequently segmented into topologically connected subgraphs. For each subgraph the distances of the vertices from the camera and their velocities relative to the camera are computed, and a partial wireframe of the object is derived from those distances. The partial wireframe is then compared with stored data relating to wireframe models to determine whether there is correspondence between the shape of the object and the shape represented by any of the models.

Abstract: In a method of forming a field-induced emission device, a cathode (3) is provided on a substrate (4), for example by etching away the substrate to leave a pointed projection. The projection may be covered with a metallic layer (5) to enhance the field-induced cathode emission. A first insulating layer (7) is formed over the substrate, with an aperture therein corresponding to the cathode position. An apertured control grid layer (9) is formed over the first insulating layer and an apertured second insulating layer (15) is formed thereon. A tunnel (18) formed by the apertures in the insulating and conductive layers is filled with a plug (19) of soluble material. An anode strip (21) is formed on the second insulating layer (15) and over the plug, and the plug is then dissolved through gaps at the edges of the anode strip, thereby leaving an unsupported area of anode strip over the cathode. The tunnel (18) may then be evacuated or may be filled with gas and the gaps at the edges of the anode strip will then be sealed to retain the vacuum or gas. If a diode structure is required, the control grid layer and the second insulating layer will be omitted. A switching device may be constructed by associating a number of the cathodes on the substrate with a common control grid and a common anode. The anode, grid and cathode structures may be so dimensioned as to form a transmission line.

Abstract: An electric switch having a contact arm (15) mounted for movement about one end (17) whose contact (19) is disengaged from a fixed contact (5) of the switch by movement of the armature (45, 47) of an electromagnetic actuator (1). The actuator armature is arranged to contact the arm only after the armature has travelled some distance and thereby gained appreciable momentum, and the point of contact between the armature and contact arm is further from said one end of the arm than the contact on the arm, thereby more effectively to open the contacts in the event of any minor welding together of the contacts.
