Abstract: A method for fabricating a solid-state lighting body, which differs from a conventional solid-state lighting body doping lighting powder in a filling material during a high-temperature calcining process, and mixes lighting powder with either organic powder or inorganic powder to form liquid mixture, thereby fabricating the solid-state lighting body in pour molding. The method is performed at a lower temperature without the high energy consumption and high equipment cost. The solid-state lighting body is easily molded at a low temperature without damaging the structure properties of the lighting powder and decreasing the lighting efficiency. As a result, the solid-state lighting body of the present invention has very good heat-resistant abilities and efficiently prevents lighting elements from high-temperature cracking resulted from long-term illumination, so as to increase use life and reliability.

Abstract: The present invention proposes substrate material favoring via hole electroplating to overcome the conventional problem that the polymer-based printed circuit board is hard to conduct electricity and likely to have poor electroplating quality. The present invention adds a conductive material to a polymeric material and controls the proportions and structure thereof to form a substrate material so as to improve the affinity of the substrate material to the metal electroplated inside the via hole with the resistance of the substrate material remaining in an allowable range. Thereby is increased yield and efficiency and saved time and cost in fabricating printed circuit boards. Further, the present invention reduces the proportion of the polymeric material with the mechanical strength remaining in an allowable range so as to decrease the overall expansion rate and obtain a fire-proof effect. Therefore, the substrate material can be used to fabricate precision products.

Abstract: A braking system is mounted on a rollator or a transport chair and includes a braking part and an operating system. The braking part is mounted adjacent to a wheel of a rollator or a transport chair. When the operating system is unactuated, the braking part abuts a corresponding wheel to avoid a rotation of the corresponding wheel. When a user wants to walk and move the rollator or the transport chair, the user can press the operating system such that the braking part departs from the wheels and releases a brake. When the user wants to sit on the seat cushion and rest, the user can keep the braking system actuated without pressing the operating system, and accordingly the rollator or the transport chair would not be slidable when sat on, thereby avoiding danger. In addition, when the user walks on a slope, the user can release their hands from the rollator or the transport chair without making the rollator or the transport chair slide down the slope.

Abstract: A mobile power supply with a data backup function and a data recovery method thereof are introduced. The mobile power supply supplies power to a portable electronic device installed with an Android operating system via a USB port. The mobile power supply copies a predetermined datum from the portable electronic device to a memory unit in the mobile power supply in conjunction with a control unit to perform first-stage data backup. Then, the USB port is electrically connected to a computer apparatus, such that the computer apparatus copies the predetermined datum from the memory unit to the computer apparatus while recharging the mobile power supply to perform second-stage data backup. Accordingly, the portable electronic device or the mobile power supply performs a data backup operation easily and quickly while being recharged.

Abstract: A linear solar energy concentrator includes a fastening rack, a concentrating lens, and a line-shaped solar panel. The concentrating lens is fastened on the fastening rack. When sunlight irradiates on and penetrates through the concentrating lens, the light is concentrated onto a focal line parallel to a direction of the linear geometric structure of the concentrating lens. The solar panel is installed under the concentrating lens and located at the focal line, wherein when an incident angle of sunlight constantly changes, the light irradiating on and penetrating through the concentrating lens still is able to be concentrated onto a same location or onto locations slightly shifted each other along the focal line on the solar panel, so as to perform an energy conversion from solar energy to electricity at a substantially same amount of light without being affected by the incident angle of sunlight.
