Abstract: A multi-functional table and chair device has a base, two opposite chair sets mounted on the base, and an adjustable table. Each chair set has at least one chair, and each chair has a supporting bracket, a seat, a backrest and a footrest. The adjustable table is mounted on the base between the chair sets and has a bottom bracket, an elevation mechanism and a table board. When the backrest of one chair is pivoted backward and the footrest is unfolded, the chair is changed into a deck chair. When the footrests of two opposite chairs of the chair sets are pivoted upward and unfolded to be horizontal and the adjustable table is raised to hold the footrests, the two opposite chairs and the adjustable table form a bed.

Abstract: A foldable leg rest has a base, a first folding assembly and a second folding assembly. The base has a mounting board and a first stage drive mechanism mounted on the mounting board. The first folding assembly is pivotally connected to the base and has a first frame and a second stage drive mechanism mounted in the first frame. The second folding assembly is pivotally connected to the first folding assembly. In use, the first stage drive mechanism is operated to drive the first folding assembly to pivot relative to the base and the second stage drive mechanism is operated to drive the second folding assembly to pivot relative to the first folding assembly. Therefore, the legs of a sitter can be stretched and placed on the folding assemblies so as to enhance comfort and minimize fatigue.

Abstract: A chair assembly has a seat, a backrest and an expandable leg supporting device. The seat has a front end and a rear end. The backrest is connected to the rear end of the seat. The expandable leg supporting device is mounted on the front end of the seat and has a base, at least one extension frame and a frame driving device. The base is mounted securely on the front end of the seat. The least one extension frame is connected to the base. The frame driving device is mounted on the base and is connected to the at least one extension frame to pivot the at least one extension frame relative to the base. Accordingly, the chair assembly can be expanded to support legs of a user in an expanded condition.

Abstract: A decorative object in the general form of a figurine having a body portion made of opaque metallic sheet and a head, including a face portion made of a transparent material such as a transparent plastic which permits passage of light therethrough. The figurine is decorated by a network of lights installed at the edges of the body of the figurine and rear of the face portion. In the dark the nature of the figurine is recognizable from its illuminated head/face portion even if the body portion is not illuminated.

Abstract: A two-wheel vehicle is provided which is secured in stationary position but wherein the front and the rear wheels of the vehicles are provided with a string of lights which twinkle annularly and thus impart the appearance that the wheels are rotating and the vehicle is in motion while in stationary mode.

Abstract: A method for aligning gesture features of image is disclosed. An input gesture image is captured, and then a closed curve formed by a binary contour image of the gesture image is determined by processing the gesture image. A curvature scale space (CSS) image of the gesture image is drawn based on the closed curve. A convolution operation is performed with respect to the sequence of a coordinate-peak set formed by the CSS image and a predefined function to designate the coordinate with maximal value of integration as a basis point for obtaining a feature parameter of the gesture image. Finally, comparing the feature parameter of the gesture image with each feature parameter of a plurality of reference gesture shapes, thereby determining a gesture shape corresponding to the gesture image.

Abstract: A chain shape illumination assembly is provided having a plurality of inter-connecting rings wherein each ring comprises a frame member defining a housing portion and a cover for said housing portion. At least one electrical lamp is secured in each housing and an electrical wire having one end electrically connected to each lamp and another end which passes through an opening in the ring and enters through an opening in an adjacent ring wherein it is connected to the lamp in said adjacent ring.

Abstract: A method for extracting and matching gesture features of image is disclosed. An input gesture image is captured, and then a closed curve formed by a binary contour image of the gesture image is determined by preprocessing the gesture image. A curvature scale space (CSS) image of the gesture image is drawn based on the closed curve. Feature parameters of a plurality of sets of the gesture image are determined by extracting first plural peaks from the CSS image as basis points, and each feature parameter of the plurality of sets of the gesture image is compared with each feature parameter of a plurality of reference gesture shapes represented as a basis point of the maximal peak, thereby determining a gesture shape corresponding to the gesture image.

Abstract: A lock structure. The lock structure includes a first element, a second element, a guiding element and a fixing pin. The first element has a guide hole and a first through hole located under the guide hole. The second element is deposed under the first element and has a second through hole that is co-axially aligned with the first through hole. The guiding element rotates and is movably disposed in the guide hole. The guiding element has a third through hole aligned with the first through hole. The fixing pin is inserted through the third through hole, guide hole, first through hole and second through hole and has a first retaining portion. The first retaining portion is formed on the lower portion of the fixing pin and located under the second element.

Abstract: A method of operating a fuzzy inference system to simplify a mesh capable of producing a high-quality approximate mesh and retaining good characteristics and appearance so that a good visual effect emerges. The invention utilizes a fuzzy inference system to integrate mesh attributes and estimate the cost in removing certain data, which serve as a criteria for mesh simplification. Hence, the invention is suitable for progressive meshes, multiresolution modeling rendering and progressive transmission on a network.
