Patent EP-0598356-A2 (EP)
Inventor: HAMADA HIDENOBU
IPC: G01R33/032
Filed: 1993-11-12
Abstract: The objective of the present invention is to provide a current sensor that does not depend on the frequency of a current to be measured. 
     A current sensor of the present invention is composed by arranging along the optic axis, successively from the side of incident light, a first polarizer (17), a Faraday cell for detection (18), a Faraday cell for modulation (1), and a second polarizer (2). A magnetic field proportional to a current to be measured is impressed on the Faraday cell for detection (18), and a periodic magnetic field for modulation that varies the angle of Faraday rotation by nπ radians, where n is a positive integer, during each period and that has a frequency higher than the magnetic field impressed on the Faraday cell for detection is impressed on the Faraday cell for modulation (17), and the current to be measured is determined based on a phase change in the intensity of the light emitted from the second polarizer of said polarization state detector. 
     A current to be measured is determined accurately from DC to high frequency without being influenced by the external environment.

Abstract: This invention relates to a crosstalk detecting apparatus for detecting crosstalk which may occur upon reading an FM-modulated signal recorded on a recording medium. This crosstalk detecting apparatus outputs a crosstalk amount from an adjacent track based on a signal read by a pickup. On a medium from which this crosstalk detecting apparatus can detect crosstalk, an image signal and an identification signal are FM-modulated and recorded on each of three tracks adjacent to one another, and the FM-modulated identification signal is recorded on each of the three tracks such that initial phases of the FM-modulated identification signals are all made equal. Also, the crosstalk detecting apparatus comprises a timing pulse generator (3) for generating a pulse at a predetermined time within the identification signal period; a phase detecting means (4) for detecting the phase difference between the signal read from the central track and a crosstalk-free signal; and a sampling circuit (5) for sampling the output from the phase detecting means (4) when a timing pulse is generated by the timing pulse generator (3).

Abstract: An improved optical low-coherence reflectometer[100,200,300,400] is disclosed for use in measuring the strength and location of optical reflections. The invention utilizes a reference signal comprising multiple copies of a light signal to increase the range of distance measurements over which the reflectometer[100,200,300,400] operates. Each copy of the light signal is delayed by a different amount. Embodiments in which the copies are generated with a ring resonator[151,251], a Fabry-Perot cavity[351], and multiple fiber delay lines[350] are described.

Abstract: Images are printed using marks formed in pixel arrays by a scanning print head. Certain special techniques well-suited for plain-paper printing have been found undesirable for use with plastic media; these techniques include so-called "resolution-enhanced technology", bidirectional printing (particularly of black), and optical-density controlled printing speed. At top and bottom of each page or sheet of printing medium, where it is undesirable to operate with the pen partly off the edge of the sheet, and where also the printing medium is constrained from only one direction rather than being held taut beneath the pen, the print mask is rotated while the printing medium is held stationary -- thereby entirely avoiding reliance upon accuracy of print-medium advance.

Abstract: A method and apparatus for improving an OCR process for recognizing unidentified characters through the creation of sets of like unidentified characters in a scanned image, deducing what the unidentified characters are with a spell checking procedure and replacing only those unidentified characters which are unambiguously determined. The order for identifying characters is strategically performed so the unidentified characters which are easier to recognize are processed before those that are more difficult to recognize. As characters become identified, relationships defined by corresponding sets allow replacing the same character in related but different textual components. As characters become recognized, other characters become more recognizable by virtue of belonging to the same textual component, such as a word, or to a related textual component such as an-other word containing the same character.

Abstract: A compact neural network architecture (10) is trainable to sense and classify an optical image (Figs 3, 6) directly projected onto it. The system is based upon the combination of a two-dimensional array (12) of amorphous silicon photoconductors (18) and a liquid-crystal spatial light modulator (20; Fig. 2). Appropriate filtering of the incident optical image upon capture is incorporated into the network training rules, through a modification of the standard backpropagation training algorithm. Training of the network (10) on two image classification problems is described: the recognition of handprinted digits (Fig. 3), and facial recognition (Fig. 6). The network (10), once trained is capable of standalone operation, sensing an incident image and outputting a final classification signal in real time.
