Abstract: A locking assembly for locking a ground engaging tool such as a shroud to a bucket lip. The bucket lip has a C-shaped boss fixed thereto. The ground engaging tool has a recess to receive a lock, the recess having an opening which is shorter in axial length than the recess. The lock is arranged to pivot about the boss as the ground engaging tool is slid rearwardly relative to the bucket lip. When the lock is located entirely within the recess, it can be accessed through a rear tunnel and tightened to hold the assembly in place.

Abstract: A low-complexity method of converting 2D images/videos into 3D ones includes the steps of identifying whether each pixel in one of the frames is an edge feature point; locating at least two vanishing lines in the frame according to the edge feature point; categorizing the frame into the one of close-up photographic feature, of landscape feature, and of vanishing-area feature; if the frame is identified to have the vanishing-area feature or the landscape feature to generate a GDM; and apply a modificatory procedure to the GDM to generate a final depth information map; if the frame is identified to have the close-up photographic feature, distinguish between a foreground object and a background information in the frame and define the depth of field to generate the final depth information map.

Abstract: A low-complexity panoramic image and video stitching method includes the steps of (1) providing a first image/video and a second image/video; (2) carrying out an image/video alignment to locate a plurality of common features from the first and second images/videos and to align the first and second images/videos pursuant to the common features; (3) carrying out an image/video projection and warping to make the first and second coordinates of the common features in the first and second images/videos correspond to each other and to stitch the first and second images/videos according to the mutually corresponsive first and second coordinates; (4) carrying out an image/video repairing and blending for compensating chromatic aberrations of at least one seam between the first and second images/videos; and outputting the stitched first and second images/videos.

Abstract: The present invention provides an integrally configured flow channel system for application in the basic structure of a paintball gun, which enables increasing speed of vaporization to produce a high working pressure. The structure is solid, and maintains high safety for the operating mechanism. The system mainly includes a gun main body having a long rectangular shape and provided with heat conducting properties, and is longitudinally defined with a bolt. A chamber is defined parallel to the bolt, and a pre-vaporizer is longitudinally defined close to the chamber and the inner surface bordering on the exterior of the gun main body. One end of the pre-vaporizer affords passage to the chamber, and another end is joined to a pressure source through a lead-in port. The pre-vaporizer effectively uses the heat effectively exchanged from the heat stored by the gun main body.

Abstract: Provided is a spreading code generating apparatus using a jacket matrix, a method thereof, and a code channel spreading device using the same. The present research provides an apparatus for generating a spread quasi-orthogonal function, which is a spreading code, by using a jacket matrix and a known short bent sequence, a method thereof, and a code channel spreading device that can acquire a minimum level of transmission power and a fine multiple access error probability in a multi-user system. The apparatus includes: a spreading code generating block for generating a spreading code by using a jacket matrix; and a spreading block for spreading external user data by using the spreading code, wherein the jacket matrix is an orthogonal matrix where an inverse matrix for a square matrix of a predetermined size having elements without zero includes inverses and transposes on an element basis.

Abstract: Provided are a method for generating a two-dimensional orthogonal variable spreading code and a Multiple Input Multiple Output (MIMO) system using the same. The MIMO system can increase a communication capacity in an asynchronous multiple user system as well as a synchronous system in a wideband-Code Division Multiple Access (CDMA). The MIMO system includes: a transmitting block for temporally and spatially encoding a plurality of user data, spreading the user data into orthogonal channel signals, and transmitting them to antennas; and a receiving block for receiving the orthogonal channel signals and performing temporal and spatial decoding and despreading on them. Herein, the transmitting block includes: a space time code (STC) encoding unit for generating and outputting a predetermined number of STC streams; and a jacket orthogonal variable spreading function (JOVSF) channel code spreading unit for spreading the STC streams into orthogonal channel signals by using a JOVSF.
