Abstract: A painting device, which is used for painting a plurality surfaces including curvature surfaces is invented. The painting devices have various shaped paint rollers that comprising the cone-shaped, V-shaped, I-shaped, wave-shaped, trapezoid-shaped, protrude-shaped, waist-drum-shaped and etc. These shaped rollers can be used singularly or by joining two or more together to form another shaped roller. Furthermore, the covered area of the roller can be changed by varying the length of the shaped rollers and the working surfaces of some of the rollers are covered by a flexible material that allows the length to be changed. These joined surfaces (corners), round rods, rectangular beams and other such structures can be finished efficiently with these rollers, respectively. The advantages of these paint rollers are painting complex structures that have multiple surfaces or various curvature surfaces with one stroke.

Abstract: A method and apparatus for fabricating a three-dimensional object from porous solid preform layers and at least a pore-filling material.

Abstract: A solid freeform fabrication process and apparatus for making a three-dimensional object. The process comprises the steps of (1) operating a material deposition sub-system for dispensing droplets of solidifiable liquid compositions on demand onto selected spots of an object work surface, for using a focused heat source to maintain a heat-affected zone on the work surface, and for creating a weld pool of molten materials on this work surface by injecting selected powder particles into this heat-affected zone and (2) during the material deposition process, moving the deposition sub-system and the work surface relative to each other in an X-Y plane defined by first and second directions and in a Z direction orthogonal to the X-Y plane so that the materials are deposited to form a first layer of the object. The material in the weld pool solidifies after the heat-affected zone moves away to build portions of a layer. These steps are repeated to deposit multiple layers for forming a three-dimensional shape.

Abstract: This is a method and apparatus for giving an accurate vehicle location and route from one location to a desired destination. This is done by catching signals from a fixed local information source through a receiver system placed in the vehicles. The present invention is called LPS (Local Position System) navigation system because it is based on a local information system instead of getting information from a satellite or city beacon. This system has two main units. The first of these units is the Address Code, this is an emitter or carrier which is placed on roads all over the nation. This unit can provide digitized and standardized road information. The second of these units is the Receiver, which can receive signals on the road and search them in a database. This database is set in the vehicle and tells the accurate location of the vehicle. It then can give precise directions to a location based on user's input. Therefore, a system user will know where he is and exactly how to get where he wants to go.

Abstract: A process and apparatus for making three-dimensional, composite material objects of a predetermined shape by sequentially depositing multiple layers of continuous reinforcement fibers and solidifying matrix material on a base member in a desired pattern.
