Abstract: A method for manufacturing a pickleball racket includes the following steps: (a) impregnating a composite material with resin; (b) wrapping a core mold, made of PolyMethylMethAcrylimide (PMI), with at least one location to form an elastic layer; wrapping the composite material around the elastic layer and the core mold to form a composite material layer, to form a semi-finished product; (c) placing the semi-finished product into a mold and heating the mold to a predetermined temperature to form internal pressure within the semi-finished product; (d) stopping heating and cooling the semi-finished product to solidify it; (e) removing a pickleball racket from the mold. The pickleball racket forms an integral structure in the order of a core mold, an elastomer layer, and a composite material layer. The pickleball racket is light in weight and has strength and rigidity. The striking surfaces of the pickle racket has hitting elasticity, and shock absorption.

Abstract: A manufacturing method and structure for a composite material racket frame includes the following steps: (a) Resin impregnation: Impregnate a composite material with resin; (b) Wrapping the core mold with composite material: Use a core mold in the shape of a racket, made of polymethacrylimide (PMI) or expanded polypropylene (EPP) material; then wrap the composite material around the core mold to form a composite material layer. The mutually wrapped composite material layers and core mold together form a semi-finished product; (c) Heating and pressurizing: Place the semi-finished product into a mold with a cavity, and heat the mold to a preset temperature. After heating, the core mold expands due to heat, forming internal pressure within the semi-finished product; (d) Cooling and curing: Stop heating and allow the semi-finished product to cool until it reaches a cured state, and (e) Finished product formation: Remove a finished racket frame from the mold.

Abstract: A linear light-emitting diode (LED)-based solid-state universal lamp comprising integrated arc and shock prevention switches normally operates with either an electronic ballast or AC mains. When such a universal lamp is installed in or uninstalled from a linear tube lamp fixture, the integrated arc and shock prevention switches can work with an electronic ballast to prevent electric arc from occurring inside the lamp, thus eliminating any possible internal fire hazard while maintaining electric shock free for installers.

Abstract: A sun tracking system includes a first, and a second photo sensors, separately mounted on a solar panel on two positions apart from one another and symmetrical with respect to a center of the panel. A first sleeve surrounds the first photosensor; a second sleeve surrounds the second photosensor. Each of the sleeves has an inclined opening with reference to the surface of the panel.

Abstract: A golf practice assembly includes a first surface which has three target areas displayed thereon and the target areas are located in a vertical axis passing through a center of the first surface. A ball has a second surface which can be attached with the first surface of the golf practice assembly. The users use different golf clubs to send balls toward the first surface. The lower target area is designed for the lower number of golf club or for shorter distance between the position that the users stand and the first surface.

Abstract: A golf practice assembly includes a target having a first surface which has three target areas displayed thereon and the target areas are located in a vertical axis passing through a center of the first surface. The users use different golf clubs and try to hit the target areas. The lower target area is designed for the lower number of golf club or for shorter distance between the position that the users stand and the first surface. A ball has a second surface which can be attached with the first surface of the golf practice assembly.

Abstract: A method of managing a print job from a computer includes the steps of transmitting print job information to a printer, storing the print job information in a storage device separate from the printer, prompting a user to enter identification information at the computer, which is separate from the printer, and comparing the identification information with information stored in the storage device. The method can also include the steps of validating the identification information, displaying the print job information at the computer, editing the print job information at the computer, updating the storage device with edited print job information, and transmitting to the printer the edited print job information. The method can be implemented using a remote manager residing on a computer connected to the printer via a network. A computer program product, and a graphical user interface for managing a document server print job are also disclosed.
