Running road recognition device

Abstract: PROBLEM TO BE SOLVED: To provide a running road recognition device capable of correctly recognizing a type of multiplex division line. SOLUTION: The running road recognition device 2 includes a white line detection ECU 6 for detecting a lane boundary (a white line) in a multiplex division line, based on the picked-up image of the multiplex division line in front of a vehicle. The storage part 16 of the white line detection ECU 6 previously stores a plurality of patterns for collation including: a template being information of the combination (the number and thickness of the lines) of respective marking lines which constitute the multiplex division line; and lane type information being information of the lane types (a solid line and a dashed line) of the respective marking lines. The white line detection ECU 6 extracts the multiplex division line from the picked-up image of the multiplex division line, determines the line type of each marking line constituting the multiplex division line, based on the extraction, determines whether a section is the section of the multiplex division line or not, collates the results with the patterns for collation, and then, identifies the type of multiplex division line.

Area division analog resistance film touch panel

Abstract: PROBLEM TO BE SOLVED: To solve problems caused by increase in the number of wiring patterns due to area division for improving reliability in an area division analog resistance film touch panel. SOLUTION: On a glass plate 111, wiring patterns 119-1 to 119-4 are formed between dispersed relay electrodes 118-1 to 118-4 and aligned external connection terminals 120-1 to 120-4. Four upper division transparent conductive film parts 133-1 to 133-4 on the lower face of a film 130 are connected to the relay electrodes 118-1 to 118-4 individually. No wiring pattern is formed on the film 130. COPYRIGHT: (C)2006,JPO&NCIPI

Color wheel and motor having the same

Abstract: PROBLEM TO BE SOLVED: To provide a color wheel that enables reliable identification of front and back, effectively obstructs a mistake in installation, enables the easy formation of an optical film, and can be manufactured at low costs and to provide a motor having the color wheel. SOLUTION: The color wheel comprises a plurality of division color wheel bodies formed in a fan shape so that disk shape whose center section has a mounting hole is achieved; the different optical films formed on the surface of the division color wheel body; an identification means for identifying the front and back of the division color wheel body; and a support for supporting the division color wheel body in the disk shape.

method and device for analyzing data

Abstract: A rule present between a plurality of data values is extracted through data mining to output the rule and the information showing the reliability of the rule. A set-division evaluation-value S-ratio and a t-value showing the clearness of division when dividing a set constituted of a plurality of data values into two subsets are defined as the information showing the reliability of a rule. S -ratio=(( S 1+ S 2 )/2)/ S 0 wherein, S 0 is sum of squares of purpose variables of set before divided, S 1, S 2 are sums of squares of purpose variables of each subset after divided.

Apparatus, system and method for managing solid-state retirement

Abstract: A storage controller is configured to determine a reliability metric of a storage division of a solid-state storage medium based on one or more test read operations. The storage division may be retired based on the reliability metric and/or the age of the data on the storage division. A storage division comprising aged data may be marked for post-write reliability testing, which may comprise determining a post-write reliability metric in response to grooming and/or reprogramming the storage division. The storage controller may project the reliability metric of the storage division to the end of a predetermined data retention period. Portions of a storage divisions that exhibit poor reliability may be removed to improve the reliability of the storage division without taking the entire storage division out of service.
