Patent MX-9708451-A (MX)
Title: Optically diffractive structure.
Inventor: STORK WILHELM
IPC: G06K19/16
Filed: 1996-04-24
Abstract: The invention relates to a structural arrangement consisting of one or more surface regions having optically diffractive structures, especially for visually identifiable security devices for valuable documents, e.g. bank notes, credit cards, identity papers or cheques or similar objects to be protected. To make it even more difficult to forge and especially copy such a structural arrangement, the invention proposes to form the structure in such a way that, to generate certain optical information in certain viewing directions, there are partial regions (10, 12, 14, 32, 34) in one or more of the surface areas (8, 30) with an identical structure (16, 18, 20; 36, 38) as far as the structure parameter of the optical depth, and that the optical depth of the structure (16, 20; 36) is constant over the extent of a partial region (10, 14; 32) but different from the optical depth of the structure (18; 38) of another partial region (12; 34).

Title: Optical switched selector.
Inventor: FATEHI MOHAMMAD TAGHI
IPC: H04Q11/00
Filed: 1997-12-17
Abstract: A gain optical selector is realized by employing an optical rare earth-doped fiber optical amplifier as the switching element per se. Each of the optical rare earth-doped optical amplifiers acts as an ON/OFF switch. Also, the gain-switched optical selector of this invention is a natural fit into today's optically amplified optical communications systems. In one embodiment, this is realized by employing a pump select circuit in conjunction with a plurality of pumps and a plurality of corresponding rare earth-doped fiber optical amplifiers. The particular pump and corresponding optical amplifier are selected by use of a monitor arrangement to determine which signal is to be selected and routed to an output. In another embodiment, a so-called tuned pump arrangement is employed in conjunction with a plurality of filters and a corresponding plurality of rare earth-doped fiber optical amplifiers. A pump tuning arrangement is employed to control the tunable pump in order to select the appropriate one of a plurality of optical input signals at any of a plurality of given wavelengths.

Title: Distributed magnetomotive force sensing
Inventor: GLENN ANDREW WILSON
IPC: G01V3/30
Filed: 2016-08-18
Abstract: A disclosed formation monitoring system includes a casing that defines an annular space within a borehole. A distributed magnetomotive force sensor is positioned in the annular space and configured to communicate with the surface via a fiber-optic cable. A computer coupled to the fiber-optic cable receives said measurements and responsively derives the location of any fluid fronts in the vicinity such as a an approaching flood front to enable corrective action before breakthrough. A disclosed formation monitoring method includes: injecting a first fluid into a reservoir formation; producing a second fluid from the reservoir formation via a casing in a borehole; collecting magnetic field measurements with a distributed magnetomotive force sensor in an annular space between said casing and said borehole, communicating measurements to a surface interface via one or more fiber-optic cables; and operating on said measurements to locate a front between the first and second fluids.

Patent NL-7909178-A (NL)
IPC: G06F11/10
Filed: 1979-12-20
Abstract: A multi-processor computer system is distributed over error-isolation areas, each of these areas containing a processor element (12, 14, 16 or 18), an encoder (20, 22, 24 or 26), a section (28, 30, 32 or 34) of a memory and an information-reconstruction section (54, 56, 58 or 60) which are connected in this order in a cyclic path. The processor elements work in parallel on the same data-word, which has a certain length. When the result of the processing has to be stored in the memory, each encoder (20, 22, 24 or 26) forms a code-symbol of shorter length, on the basis of the data-word. The set of code-symbols formed on the basis of the data-word forms a code-word with a larger bit length than the data-word mentioned. By means of an error-correcting code at least one erroneous code-symbol in the code-word can be corrected. The code symbols are stored in the respective memory sections (28, 30, 32 or 34). If the data-word concerned has to be further processed, all corresponding code-symbols are fed to all information-reconstruction sections (54, 56, 58 or 60). Peripheral equipment can be connected in the cyclic path, with implementation of distinctive levels of redundancy.
