Patent GB-2244620-A (GB)
Title: Error analysis in direction and position finding
Inventor: ALCOCK ROBERT NICHOLAS
IPC: G01S5/04
Filed: 1990-06-01
Abstract: The invention relates to analysing clusters of bearings (A, B, C and D) taken of distant sources by an array of direction finding stations. Each bearing has an error +/-E and a triangulation process is used to fix the position of the sources. A combination of bearings are taken one each from the stations. Each bearing of the combination is taken in turn as a spoke (30) directed at a source. The triangulation process generates a bar (31, 32, 33) of intersection points along the spoke for each other bearing of the combination, each bar corresponding to the error +/-E of each other bearing. The number of overlaps between pairs of bars along a spoke is total led to give a spoke score. The spoke scores for all spokes of the combination is summed to form a fix confidence score for a source which may be associated with the combination, or cluster, of bearings. Methods are also provided for rejecting redundant fixes associated with subsets of bearings within a cluster. <IMAGE>

Abstract: A stream of signatures which are effectively thicker along one edge than an opposite edge are conveyed in a stream in an edge-standing condition with the thicker edges being upright by belts 40 of conveyor 19 on each side of the signatures, the belts on opposite sides are operated at different speeds to compensate for skewing of the signatures induced by the thickening upstanding edges. The lower belt of three on each side are shorter than those above, so that it lies adjacent the skid (38 figure 3 not shown) on which the signatures rest (figure 8 not shown). The conveyor is in a known signature bundling machine in which shingled signatures are raised to stand on edge at 12A, consolidated by conveyor 18, and separated into groups before bundling. <IMAGE>
Patent GB-2247798-A (GB)
Title: Optical receiver
Inventor: GOODCHILD GATH
IPC: H04B10/69
Filed: 1990-09-06
Abstract: An optical receiver with extended dynamic range includes an optical detector (3), a transimpedance amplifier (1, 2) and a variable impedance network (D, Tr1). The d.c. component of the detector output is employed to control the variable impedance such as to prevent overload of the detector and the transimpedance amplifier front end (1). The a.c. and d.c. components of the feedback signal are separated by a capacitor (C2) so that only the a.c. component is coupled to the front end. The voltage drop across resistor r due to the d.c. component of the detector output serves to switch on transistor Tr1 at high input light levels, a.c. components being removed by a filter network (R3, C3), and permit diode D to conduct excess current away from the detector and the front end. The FET first stage of the transimpedance amplifier is replaced by a bipolar device for bit rates in excess of 30 MBits/s. <IMAGE>
