3266 results about "Diagonal" patented technology

In geometry, a diagonal is a line segment joining two vertices of a polygon or polyhedron, when those vertices are not on the same edge. Informally, any sloping line is called diagonal. The word diagonal derives from the ancient Greek διαγώνιος diagonios, "from angle to angle" (from διά- dia-, "through", "across" and γωνία gonia, "angle", related to gony "knee"); it was used by both Strabo and Euclid to refer to a line connecting two vertices of a rhombus or cuboid, and later adopted into Latin as diagonus ("slanting line").

Backlight for correcting diagonal line distortion

A backlight apparatus has a collimating waveguide with a light input end, a top surface, a bottom surface, opposing sides, a far end opposite the light input end, and a total internal reflection critical angle for the material of the waveguide. A plurality of first facets are formed in the bottom surface distributed along the waveguide between the light input end and the far end. Each of the first facets has a first facet bottom surface which converges toward the top surface in a direction away from the far end relative to the top surface. A light scattering and reflective surface is disposed adjacent the far end of the collimating waveguide. The first facet bottom surfaces cause light rays entering the light input end to be totally internally reflected to the far end of the collimating waveguide wherein the scattering and reflective surface at the far end reflects and scatters light rays incident thereon back toward the light input end. The first facet bottom surfaces then cause the light rays reflected from the far end to exit the top surface. The first facet bottom surfaces may be formed either as straight facets or as curved surface facets and may also be alternatively formed having a reflective material layer thereon.

Payline system for multiline slot play using an erasing/exposure feature

A method of playing a virtual or virtual / mechanical multireel slot game. A grid of at least 3 rows×3 columns, but preferably 3 rows×5 columns, is presented on a screen, with a second, opaque blanketing layer of color or graphics over the grid, so as to hide symbols on the reels below. After the wager, reels on the bottom layer spin (or are virtually and randomly positioned in any manner), hidden from the player by the blanketing layer. An “erasing” indicium then glides from outside the grid (preferably across the top row of 5 reels, from left to right), over the blanketing layer, erasing the color layer to expose the symbols on the reels below. The indicium preferably (or always) moves in one direction only until it hits the end of a row, the top or bottom of a column, or a revealed symbol that alters movement of the indicium. When the indicium encounters this situation, it may hesitate for a moment, then randomly pick a direction in which to continue. It may continue in the same direction or turn 90° clockwise or 90° counterclockwise. It may even move diagonally. If the indicium turns and continues over the reels, more symbols are revealed until the indicium again reaches a turning point. Payouts are awarded according to a predetermined paytable for single special symbols and / or for sets such as multiple same symbols shown, whether the symbols are contiguous or not.

Golf club with diagonally reinforced contoured front wall

A golf club head composed of a forged metal material has a striking surface that is supported by diagonal stiffening regions that extend from a central region of the face toward the heel-sole quadrant, heel-crown quadrant, toe-crown quadrant, and toe-sole quadrants of the face. The diagonal stiffening regions are smoothly contoured to blend into the back surface of the face so as to avoid any stress concentrations. By extending the stiffening regions diagonally from the center of the club face to the four quadrants, a more uniform stress distribution can be obtained and therefore more uniform performance. Additionally, since the diagonal stiffening regions are greater in length than vertical or horizontal stiffening region could be made, the center of the face can deflect a greater amount without exceeding the yield strength of the material and, therefore, there is a more efficient transfer of energy from the club head to the ball.

7FAstage 1 abradable coatings and method for making same

A method of applying a profiled abradable coating onto a substrate in which an abradable ceramic coating composition is applied to a metal substrate using one or more coating application techniques to produce a defined ceramic pattern without requiring a separate web or grid to be brazed onto the substrate. The invention is particularly designed to withstand the higher operating temperatures encountered with the stage 1 section of 7FA+e gas turbines to allow for increased coating life without significant deterioration in structural or functional integrity. Typically, the grid pattern coating begins approximately 0.431″ after the leading edge of the shroud, and ends approximately 1.60″ before the trailing edge of the shroud. In the case of diamond-shaped patterns, the grid pattern will be about 0.28″ long and 0.28″ wide, with an overall thickness of about 0.46.″ The coatings thus provide the required levels of abradability and leakage performance and may be applied as a chevron or diamond pattern with the shape oriented such that the diagonals run perpendicular and parallel to the sides of the shroud.

Rear-mounted aerodynamic structure for truck cargo bodies

This invention provides a foldable / retractable and unfoldable / deployable, rearwardly tapered aerodynamic assembly for use on the rear trailer bodies and other vehicles that accommodate dual swing-out doors. The aerodynamic assembly includes a right half mounted on the right hand door and a left half mounted on a left hand door. Each half is constructed with a side panel, top panel and bottom panel, which each form half of an overall tapered box when deployed on the rear of the vehicle, the bottom panels and top panels being sealed together at a pair of overlapping weather seals along the centerline. The panels are relatively thin, but durable, and are joined to each other by resilient strip hinges. The top and bottom panels are also hinged to form two sections along diagonal lines to facilitate folding of all panels in a relatively low-profile stacked orientation. This low profile allows the doors to be swung through approximately 270 degrees to be secured to the sides of the body in a manner that does not interfere with adjacent doors or bodies in, for example a multi-bay loading dock. A swing arm assembly and gas spring biases the panels into a deployed position that can be refolded by grasping the side panel and rotating it inward toward the door surface. The top and bottom panels are partly inwardly folded when deployed to define external valleys using a stop assembly. This ensures that the panels fold readily when desired without the two sections of the panels “locking up”.

The subelements making up the elements in of the subarrays is preferably quadrilateral. Adjacent subelements in each element are electrically connected via an interconnect portion such that the interconnect portion connecting each pair of adjacent subelements in each element is substantially linear and is aligned with the diagonals of the adjacent subelements. A preferred acoustic lens is curved in both azimuth and elevation directions, whereby the subarrays are independently focusable. By transmitting in one plane and simultaneously receiving in a different, orthogonal plane, a system including the array can image a 3-D region of interest (ROI). In a volumetric embodiment of the invention two orthogonal B-mode images of a structure within the ROI are displayed simultaneously. The user may then trace the outlines of the images and the system therefrom calculates the volume of the structure.

Forward error correction for burst and random packet loss for real-time multi-media communication

This invention relates generally to a packet recovery algorithm for real-time (live) multi-media communication over packet-switched networks, such as the Internet. Such multi-media communication includes video, audio, data or any combination thereof. More specifically, the invention comprises a forward error correction (FEC) algorithm that addresses both random and burst packet loss and errors, and that can be adjusted to tradeoff the recoverability of missing packets and the latency incurred. The transmitter calculates parity packets for the rows, columns and diagonals of a block of multi-media data packets using the exclusive or (XOR) operation and communicates the parity packets along with the multi-media data packets to the receiver. The receiver uses the parity packets to recover missing multi-media data packets in the block. The FEC algorithm is designed to be able to recover long bursts of consecutive missing data packets. If some parity packets are missing, they too can be recovered using an extra single parity packet, so that they can be used to recover other missing data packets. The invention applies to both one-way real-time streaming applications and two-way real-time interactive applications, and to both wired and wireless networks. The invention retains backwards compatibility with existing standards governing FEC for professional video over IP networks.
