Patent Name: Hydraulic boosting steering system and direction locking method Abstract: The invention claims a hydraulic boosting steering system and direction locking method; it is to set a tyre pressure monitoring instrument in vehicle tyre for detecting the abnormal signal of tyre pressure; the tyre pressure monitoring instrument can rapidly wirelessly transmit the detected abnormal signal to electronic control unit (ECU) which sends out an electric signal to simultaneously activate two electric magnets through leads, control the on-off operation of the oil path of said two two-bit two-way electromagnetic valve and prevent the flowing of hydraulic oil through said hydraulic one-way valve to realize the direction locking. This invention has no effect on any direction changing by the driver, but timely locks the driving direction of guiding tyre under the circumstances of abnormal tyre pressure, especially when tyre explodes. Furthermore, the valve core of said two-bit two-way valve in this invention is set to be spherical structure, which avoids the friction with the hole wall and greatly decreases the dumping effect of hydraulic oil to decrease the power of electromagnet without any blocking. Claims: 1 A hydraulic boosting steering system comprises steering control valve controlling the flowing direction of hydraulic oil and boosting cylinder; wherein the steering system further comprises a direction locking device set between the steering control valve and boosting cylinder; said direction locking device comprises two two-bit two-way electromagnetic valves and two hydraulic one-way valves; wherein each two-bit two-way electromagnetic valve have serial connection with one hydraulic one-way valve and then are respectively connected to the oil path in vehicle steering system; the on-off of said two-bit two-way electromagnetic valve is controlled by the electronic control unit. 2 The hydraulic boosting steering system according to claim 1, wherein the v

Patent Name: Flat panel display and manufacturing method, manufacturing device, image quality controlling method and device Abstract: This invention claims a flat panel display and manufacturing method, manufacturing device, image quality controlling method and device for reducing recognition degree of defect pixel and electrically compensating the charging characteristics of defect pixel. In the flat panel display, the display panel has linking pixel; several data lines and several scanning lines cross together and form several pixels and the defect pixel is electrically connected to the normal pixel near it. The memory stores the position data expressing the position of said linking pixel and the compensation data compensating the charging characteristics of said linking pixel. The compensation circuit regulates the digital video data to be displayed on the linking pixel according to the position data and compensation data. Claims: 1 A flat panel display comprises display panel with linking pixel to make several data lines and several scanning lines cross together and form several pixels, near which the defect pixel is electrically connected to the normal pixel; memory, storing the position data expressing the position of said linking pixel and the compensation data compensating the charging characteristics of said linking pixel; compensation circuit, regulating the digital video data to be displayed on the linking pixel according to the position data and compensation data. 2 The flat panel display according to claim 1, wherein the normal pixel near the defect pixel displays the color same as the color displayed by defect pixel. 3 The flat panel display according to claim 1, wherein said compensation data is differently set according to gray scale of data to be displayed on linking pixel. 4 The flat panel display according to claim 1 also comprises several switch components formed in the area confirmed by the cross between the data line and sca

Patent Name: Method of establishing symbol patterns, obtained symbol patterns, method and system of finding out the position of symbol patterns and computer program product operating the method Abstract: This invention claims a method of establishing symbol patterns, obtained symbol patterns, method and system of finding out the position of symbol patterns and computer program product operating the method, related to a method of establishing dimensional symbol patterns which can be used for confirming the position in large area covered by said patterns, e.g. used for recording handwritten information by pen analogous tools. The invention is useful for establishing symbol patterns with expected property able to accurately confirm positions, namely, any big enough observing part of the pattern is unique. The symbol pattern is based on non-repeated sequence of symbol value Sk, each of which is corresponding to the fixed linear combination of coefficient of the monomial in xkmodP(x); wherein, P(x) is arbitrary polynomial of degree n in field Fq. Symbol patterns are generated through folding sequences according to wrap plan. The invention also claims a method and system for finding out the position of a group of observing symbol values in said symbol patterns and a computer program product operating said methods. Claims: 1 A method of establishing dimensional symbol pattern Pw; said dimensional pattern has the following properties, namely, any subset with a symbol value of m observed in said symbol pattern is unique; the method comprises defining the non-repeated sequence S of symbol value Sk, each of which is corresponding to the fixed linear combination of coefficient of the monomial in xkmodP(x), wherein, P(x) is arbitrary polynomial of degree n in field Fq; defining mask patterns with defining shape and generating mask vector B with said observed m symbol values; and defining wrap plan W for folding said sequence to be said dimensional pattern Pw.
