An ultra-high-density vertical cross-point array comprises a plurality of horizontal line layers having horizontal lines interleaved with a plurality of vertical lines arranged in rows and columns. The vertical lines are interleaved with the horizontal lines such that a row of vertical lines is positioned between each consecutive pair of horizontal lines in each horizontal line layer. Each vertical line comprises a center conductor surrounded by a single or multi-layered memory film. Accordingly, when interleaved with the horizontal lines, two-terminal memory cells are integrally formed between the center conductor of each vertical line and each crossing horizontal line. By configuring the vertical and horizontal lines so that a row of vertical lines is positioned between each consecutive pair of horizontal lines, a unit memory cell footprint of just 2F2 may be realized.

The disclosed invention reduces the power consumption of a liquid-crystal device. A shift register section includes DX selection circuits and shift registers, which are divided into blocks. An X clock signal is supplied to a block in which the image data values do not match between horizontal lines which are adjacent in a data time-series manner, and is not supplied to a block in which the image data values match.

For this reason, it is possible to reduce electric power for driving an X clock signal supply line and an image data supply line.

A two-dimensional fast Fourier transform is carried out on a block of sample points by executing a one-dimensional fast Fourier transform on all vertical lines of sample points, storing the resulting values at one or more specified positions in each vertical line in an internal buffer, and then executing a one-dimensional fast Fourier transform on each resulting horizontal line of transformed data. This entire process is repeated, the specified positions being changed at each repetition, until all horizontal lines have been processed. The necessary amount of buffer memory is reduced because the internal buffer only has to store intermediate results for a limited number of horizontal lines.

The invention provides a real-time lane line detection method. According to the real-time lane line detection method, an interested area is determined through the position of a current frame vanishing point, and an upper half image where no lane lines exist is removed, and therefore, the processing time of each frame of image can be decreased; edge point scanning is performed at two directions from inside to outside of the interested area, and what is detected every time is the inner side of a lane line which is most adjacent to vehicles on a lane, and except for the interference of other edge points, jigger will not be generated because of the width of the lane line, and since an image is divided into two half parts of detection lane lines from the position of the vanishing point, a situation that two detected straight lines are located at one side of the vanishing point when the entire image is detected can be avoided, and thus, the accuracy of the detection can be improved; and further, when Hough transform lane line detection is performed, only straight lines in a range of straight lines which can form a certain included angle with a horizontal line are selected, and therefore, the accuracy of the detection can be improved, and time for calculating Hough weight of straight lines that are not in the range of the straight lines can be saved. With the real-time lane line detection method of the invention adopted, lane line detection at highways and rural areas where roads are in good condition can be realized rapidly, accurately and stably.

The disclosed method and system may be used for creating advanced protection means for various categories of documents (e.g. bank notes, identity documents, certificates, checks, diploma, travel documents, tickets) and valuable products (e.g optical disks, CDs, DVDs, CD-ROMs, prescription drugs, products with affixed labels, watches) hereinafter called “secure items”. Secure items are authenticated by shape level lines. The shape level lines become apparent when superposing a base layer comprising sets of lines and a revealing layer comprising a line grating. One of the two layers is a modified layer which embeds a shape elevation profile generated from an initial, preferably bilevel, motif shape image (e.g. typographic characters, words of text, symbols, logo, ornament). In the case of an authentic document, the outline of the revealed shape level lines are visual offset lines of the boundaries of the initial bilevel motif shape image. In addition, the intensities, respectively colors of the revealed shape level lines are the same as the intensities, respectively colors of the lines forming the base layer sets of lines. By modifying the relative superposition phase of the revealing layer on top of the base layer or vice-versa (e.g. by a translation or a rotation), one may observe shape level lines moving dynamically between the initial bilevel motif shape boundaries and shape foreground centers, respectively background centers, thereby growing and shrinking. In the case that these characteristic features are present, the secure item is accepted as authentic. Otherwise the item is rejected as suspect. Pairs of base and revealing layers may be individualized by applying to both the base and the revealing layer a geometric transformation. Thanks to the availability of a large number of geometric transformations and transformation parameters, one may create documents having their own individualized document protection. The invention also proposes a computing and delivery system operable for delivering base and revealing layers according to security document or valuable product information content. The system may automatically generate upon request an individually protected secure item and its corresponding authentication means.

An apparatus for processing passive acoustic signals received on a horizontal line array that were either emitted from an underwater object or echo returned from an object, is proposed to track the motion (bearing change and range change) of an object (target) relative to the receiver horizontal line array. Adaptive array processing for a moving object is biased for a moving source when the number of data samples is limited by the stationariness condition. Motion compensation can be carried out in the beam domain by beam shifting for a bearing changing object and frequency shifting for a range changing object. The method includes receiving acoustic signals from the target, determining the beam covariance matrices, determining the target bearing rate and range rate, processing the beam covariance matrices by compensating for the target motion, and producing a beam power plot versus time. Interference signal is suppressed when the interference source does not have the same motion (bearing and range rate) as the target. The method does not need detailed environmental acoustic information of the sound channel normally required to model the sound propagation.

The bipod support includes lockable controls for selectively limiting panning, tilting and canting in a manner which lets the shooter or user easily respond to changing situations when in the field.
