Drive control system for a fiber-based plasma display

A full color fiber plasma display device includes two glass plates sandwiched around a top fiber array and a bottom fiber array. The top and bottom fiber arrays are substantially orthogonal and define a structure of the display, with the top fiber array disposed on a side facing towards a viewer. The top fiber array includes identical top fibers, each top fiber including two sustain electrodes located near a surface of the top fiber on a side facing away from the viewer. A thin dielectric layer separates the sustain electrodes from the plasma channel formed by a bottom fiber array. The bottom fiber array includes three alternating bottom fibers, each bottom fiber including a pair of barrier ribs that define the plasma channel, an address electrode located near a surface of the plasma channel, and a phosphor layer coating on the surface of the plasma channel, wherein a luminescent color of the phosphor coating in each of the three alternating bottom fibers represents a subpixel color of the plasma display. Each subpixel is formed by a crossing of one top fiber and one corresponding bottom fiber. The plasma display is hermetically sealed with a glass frit. The sustain and address electrodes are brought out through the glass frit for direct connection to a drive control system.

News recommendation method and device based on ontology model library

The invention provides a news recommendation method and device based on an ontology model library. The method comprises the following steps: (1) carrying out preprocessing which includes punctuation, word segmentation, part-of-speech tagging and the like; (2) carrying out news ontology identification: identifying news ontology information in an input news text; (3) carrying out key information mining: combining with the identified news ontology information to mine key information (including keywords, key ontologies and the like) in an input news discourse; (4) carrying out attribute acquisition: on the basis of the information obtained in the previous steps, inquiring a knowledge graphto obtain knowledge point attribute information, carrying out expansion according to the relationship of the mapping knowledge domain, and further mining the attribute information; (5) carrying out dimension generation: on the basis of the information (including the ontology, the keyword, the attribute and the like) obtained in the previous steps, generating a recommendation dimension; and (6) carrying out recommendation knowledge recalling: on the basis of the recommendation dimension, obtaining the recommendation knowledge in a news document library and the knowledge library.

Portable Braille reader

The invention belongs to the field of Braille readers and relates to a portable Braille reader which is convenient for the blind to use for reading e-books. An enclosure (1) is provided with a full-page-type Braille dot display screen (15), functional keys and a USB interface J2. A hardware control system is installed in the enclosure (1) and composed of an FPGA master control module (11), a USB communication module (10), a power management module (9), a high-voltage driving module (13) and a Braille dot matrix driving module (14). By operating the functional keys, selection is made as required, data information in a U-disk can be transferred to the FPGA master control module (11) through the USB communication module (10), corresponding software is executed, a corresponding function is completed, and thus the blind can read fast and conveniently through the Braille dot display screen (15). The portable Braille reader is small in size and convenient to carry; the portable Braille reader accords with the operation habit of the blind and thus is convenient for the blind to use for recognizing and reading; the reading cost can be reduced for the blind, the portable Braille reader is good for the blind to participate in the society equally, the living standard is raised, and the portable Braille reader has good public welfare.

Method for filtering and monitoring behavior of program

The invention relates to a method for filtering and monitoring the behavior of a program. The method for filtering the behavior of the program comprises the following steps: constructing a behavior sample database which comprises behavior samples collected from a plurality of program samples, and the weight of each behavior sample calculated based on the frequency of occurrence of the behavior sample, wherein the weight can be an inverse document frequency index, the probability of occurrence and the like; acquiring the behavior of the program to be processed, judging whether a behavior sampleidentical to the behavior of the program exists in the behavior sample database, if the behavior sample identical to the behavior of the program does not exist in the behavior sample database, keeping the behavior of the program; and if the behavior sample identical to the behavior of the program exists in the behavior sample database, judging whether the weight of the behavior sample falls intoa preset filtering threshold range, if so, filtering the behavior of the program, otherwise, keeping the behavior of the program. The method can reduce the interferences to monitoring or analysis caused by non-characteristic behaviors, reduce the treating capacity, and improve the accuracy.
