Abstract: A generator control system is coupled to a motor generator. The system includes a DC port, a first switch unit, a DC bus, a first power conversion circuit, a second power conversion circuit, and a second switch unit. The first power conversion circuit has a first side coupled to the DC bus and a second side coupled to the first switch unit. The second power conversion circuit has a first side coupled to the DC bus and a second side coupled to the motor generator. One end of the second switch unit is coupled to the first power conversion circuit and the first switch unit, and the other end of the second switch unit is coupled to the DC port.

Abstract: A mesh material for fabricating hunting blinds, tents, and other similar flexible structures. The material is durable, water-resistant, and partially light-transmissive such that persons or objects inside or behind the structures are not easily seen from outside the structures. The material is also semi-permeable to air flow for ventilation purposes. The mesh material is fabricated from an interwoven polyester, polyurethane, or polyvinyl chloride (PVC) fabric that is coated with acrylic and a mixture of silicone and ethylene vinyl acetate (EVA). Patterns and/or colors are printed on both sides of the fabric with a heat transfer paper printing process to provide a desired level of light transmissivity.

Abstract: A hat comprises a crown, a brim extending outward from an edge of the crown, and a first transparent liquid-proof layer disposed over the crown or the brim. The first transparent liquid-proof layer and the crown, or the first transparent liquid-proof layer and the brim, define an enclosed space containing a liquid and decorations. By forming the enclosed space that allows a user to see through it on the hat and disposing the liquid and the decorations into the enclosed space, the hat may present special visual effects different from that presented by conventional hats.

Abstract: A mailbox including a box having a box door, a first box door, a photocell circuit, and a cartridge. The box door is pivotally connected to a first wall of the box. The cartridge includes a light source and an electric power source. The light source illuminates an interior surface of the box. The photocell circuit includes a photocell panel. The photocell circuit charges the electric power source using energy acquired by the photocell panel. The electric power source powers the light source. The cartridge is removably mounted to a second wall of the box to electrically connect and disconnect the cartridge to the photocell circuit.
