Patent EP-0384556-A2 (EP)
Inventor: SCARR ROBERT WALTER ALISTER
IPC: G06V10/88
Filed: 1990-01-04
Abstract: A holographic optical correlator includes a matched optical filter and control means therefor including a memory. In use, searching for occurrences of an item to be found is carried out by the control means controlling the input and Fourier transform planes of the filter and a coherent light source for parallel optical processing of the memory content and the output plane of the filter provides information to the control means as to the location in the memory of occurrences of said item. The item and the memory as input to the input plane are coded by means of an M out of N code, where M is a constant in order to solve threshold tolerance problems. Specifically a sparse code (3 out of 13) is used for octet data. Preferably the item recognition is a two stage process. In a first stage, individual characters of a string are matched and in a second stage there is recognition of the correct relative juxtaposition of characters in the string.

Abstract: Disclosed is a method of obtaining data to determine a rotation matrix  R , for rotating the axes (x,y,z) of an analogue probe coordinate system (PCS) onto the axes (X,Y,Z) of a machine coordinate system (MCS). The head (14) of the machine is driven to bring a measuring tip (16) of a stylus (12) supported by the probe for movement relative to the head (14) into engagement with a kinematic location (20). With the tip (16) fixed in the location (20) the head is then moved to six different locations. The coordinate positions of the head (14) in the machine coordinate system (MCS), and the stylus (12) in the probe coordinate system are used to set up six simultaneous equations and thus determine the rotation matrix  R .

Abstract: First and second signals, with given bias levels are applied to respective inputs (out 1, out 2) of a non-additive mixer (NAM) circuit (100) through respective switches (SW1,SW2) which can be in a low-cost CMOS switch (30) to provide a cost effective switch for television signals. Each input of the NAM circuit is biased at a reference level (through R1,R3) in the absence of applied signal to it. The input receiving signal plus bias is enabled thereby to convey its respective signal to the output (40) of the NAM circuit (100), and the input receiving the reference bias level is prevented from conveying its respective signal to the output (40) of the NAM circuit (100).

Abstract: A fixing cartridge (20) is mounted on the slide of a linear-movement unit. The slide can be moved and positioned on at least one guide rod (8). The fixing cartridge (20) contains two clamping members (34r, 34l) of identical design orientated symmetrically to one another with regard to a surface disposed perpendicularly on the guide rod. The clamping members (34r, 34l) have head pieces (38r, 38l) sitting on the guide rod (8) and control surfaces (50l) which are remote from the head pieces (38r, 38l) and via which the clamping members are expanded by an expanding pin (48) so that the head pieces hold fast on the guide rod (8). The expanding pin (48) is held by an annular sleeve (46) which surrounds the clamping members and against which a pressure member (54) acts against the preloading force of a helical spring (44). The pressure member is located at the base of a cylindrical housing into which a fluid line leads.

Abstract: A light pipe (100) used for backlighting liquid crystal displays (D) has a planar front surface (110) and a stepped or faceted back surface (112). Light is injected from the ends (105) of the light pipe from cold or hot cathode, apertured, fluorescent lamps (108). The cold cathode lamps are preferably insulated to raise their operating temperature. The back surface has a series of planar portions (114) parallel to the front surface connected by facets (116), which are angled so that the injected light reflects off the facets and through the front surface. A reflector (126) having a planar, highly reflective, highly scattering surface or a sawtoothed or grooved upper surface is located adjacent to and parallel with the light pipe back surface to reflect light escaping from the back surface back through the light pipe to exit the front surface. The axes any grooves are preferably slightly skewed from the facet axis to reduce moire pattern development. A low scattering or loss diffuser (111) is located adjacent to and parallel with the light pipe front surface to reduce moire pattern development. The liquid crystal display (D) is located over the low scattering diffuser. A separate injector (104) may be located between the lamp and the light pipe to better couple the light into the light pipe.

Abstract: An optical fiber coil (16) in a fiber optic gyro is formed by a single mode optical fiber (16a) and two polarization retaining optical fibers (16b, 16c) of the same length and connected to both ends of the single mode optical fiber. The polarization optical fibers and an optical fiber coupler (14) are connected, and clockwise and counterclockwise light beams are distributed and supplied by the optical fiber coupler to the optical fiber coil, and the both light beams having returned to the optical fiber coupler are thereby caused to interfere with each other. The lengths of the X-axis and Y-axis components of light are displaced apart in phase to such an extent as not to interfere with each other, by the birefringent property induced in the coil of the single optical fiber and the birefringent property of the polarization retaining optical fibers themselves.

Abstract: An asynchronous, fiber optic, ring network (10) includes a number of nodes where data enters and exits the network. Each of these nodes has its own clock (640) to provide timing needed by equipment at that node. So that synchronous data can be transmitted between predetermined nodes, a master node (100, 200) provides timing information which may be used at any node to synchronize its clock. Timing information comprises the propagation delay around the ring (ring latency) as measured by the master node. This measure of propagation delay is transmitted by the master node as an information packet (310) available at all nodes. Synchronization of any other node (110,300) with the master requires that the other node perform its own measurement of propagation delay, compare its measurement with that of the master node, and make adjustments to its own clock that tend to decrease the difference between these measurements.
