Three-dimensional position information of each of feature points in a left and a right image is calculated based on a disparity between the left and right images; a lane marker existing on a road surface is detected from each of the left and right images; based on three-dimensional position information of a lane marker in a neighboring road surface area, by extending the lane marker to a distant area, a lateral direction position, and a depth direction position, of the extended lane marker in the distant area are estimated; an edge segment of a certain length or more is detected from feature points in the distant area in each of a plurality of images; three-dimensional position information of the edge segment is calculated; and, based on the three-dimensional position information of the edge segment, and on the extended lane marker information, a road incline in the distant area is estimated.

A bucket assembly is provided with a kit that includes a base plate for permanent connection to a lower part of the bucket, and sacrificial, impermanent replaceable wear edge segments for the forward lip and corner leading edges of an excavator or loader bucket. These segments form a set of “bolt on” cast wear members and wing wear segments. The base plate and wear plates are drilled and machined to accommodate the precision fitting bolting on of the replaceable lips and cast wing segments. The cast lip segments are of both left and right hand configurations and come in a variety of widths that, in combination, may tend to fit a large number of different commercially available bucket sizes. The lip top and bottom faces are shaped in a profile that may tend to result in relatively uniform wear and a reduction in friction when digging into various materials.

The invention discloses a method and apparatus for modifying, as appropriate, the geometries of a polygon. Based on various attributes associated with the polygon and its surroundings, modification of the location of the edge segments may conditionally occur. Additionally, if these modifications occur, a method to minimize the introduction of short edges during the modification is provided.

A method of image processing is provided which includes non-recursive hysteresis thresholding in Canny edge detection. The non-recursive hysteresis thresholding reduces computational complexity and eliminates the potential for call stack overflow. More specifically, hysteresis thresholding is performed in a raster-scan order pass over the image data to connect edge segments to form continuous edges.

A touch screen comprising a flexible sheet comprising a substantially planar surface and integral compressible spacer dots formed thereon, where each spacer dot comprises a base cross section in the substantially planar surface of the flexible sheet defined by a first point or set of connected points intersecting an axis in the substantially planar surface, a second opposed point or set of connected points intersecting the axis, and first and second continuous edge segments connecting the first and second points or end points of the first and second sets of points on opposite sides of the axis, wherein the spacer dot has a variable height perpendicular to the substantially planar surface along the axis, and wherein the surface of the spacer dot extending above the base cross section is not equidistant from the mid-point of the axis between the intersections of the first and second points or sets of connected points and the axis.

A CMOS structure is disclosed in which a first type FET contains a liner, which liner has oxide and nitride portions. The nitride portions are forming the edge segments of the liner. These nitride portions are capable of preventing oxygen from reaching the high-k dielectric gate insulator of the first type FET. A second type FET device of the CMOS structure has a liner without nitride portions. As a result, an oxygen exposure is capable to shift the threshold voltage of the second type of FET, without affecting the threshold value of the first type FET. The disclosure also teaches methods for producing the CMOS structure in which differing type of FET devices have their threshold values set independently from one another.

A fuser assembly for an electrophotographic imaging device includes a heater including a substrate, a resistive trace disposed and running along a length of the substrate for generating heat for fusing toner to a sheet of media when a current is passed therethrough, and at least three conductors for passing current through the resistive trace. The at least three conductors include a first conductor connected to a first end portion of the resistive trace, a second conductor connected to a second end portion of the resistive trace, and a third conductor connected to the resistive trace at a location between the first end portion and the second end portion thereof. A temperature sensor senses a temperature of an edge segment of the substrate. Based upon the temperature sensed, circuitry selects between the first conductor and the third conductor for passing current through the resistive trace.

A method of manufacturing a plurality of secondary containment panels and assembling and installing the panels in a secondary containment system of an above-ground liquid storage tank or other retention facility includes forming a plurality of flexible substrate pieces. A liquid impermeable coating is applied to the upper surface of each piece such that an edge segment of the piece remains uncoated. The coating is applied to the substrate piece in an indoor enclosure. The coated pieces are delivered to the site of the tank and extended across the ground adjacent to the tank. At least a pair of the pieces are juxtaposed relative to one another such that a first one of the pieces overlaps the uncoated segment of the second piece to form a seam. An adhesive substance is then applied to the seam to fasten the first and second pieces together.

An edge detecting method detects edge segments by searching all of the search lines forming an image from an end of the image in a direction perpendicular to the edges. If a line whose edge segment cannot be detected exists, a search is made in all of the search lines from the vicinity of the center of the image toward the end of the image, whereby edge segments are detected. A linear edge is determined from edge segments. A plurality of edge candidates are obtained from the edge segments for all of the search lines, and an optimum candidate is selected from among the edge candidates. Ruled lines are extracted from the source document in the image, and an optimum candidate is selected based on a comparison with a ruled line. As a result, an edge of the source document can be detected with high accuracy even if an image on a background side is unstable, or if materials of the background and the source document are similar.

Automated techniques to correct certain rule violations with respect to non-design geometries are used, simplifying and automating the design layout of an electronic circuit, whether embodied as a design encoding or as a fabricated electronic circuit. Correcting minimum width rule violations of non-design geometries is accomplished by forming one or more cutting areas adjoining one or more erroneous edges of a non-design geometry, and deducting the cutting areas form the non-design geometry, splitting the non-design geometry into two or more remaining non-design geometries. Any slivers of remaining non-design geometries, i.e., any pieces that are smaller than a minimum size amount, are removed. Cutting areas are formed by stretching ends of erroneous edge segments by a minimum width rule amount and sizing the stretched edge segments which are inside the non-design geometry outward by a minimum spacing rule amount.
