Abstract: A helmet has a memory foam member and an impact dissipating member in moulded together. A process for forming such a helmet is also provided. A helmet has a memory foam member and an impact-dissipating member. The memory foam member is formed from a memory foam material and the impact-dissipating member is formed from an impact-dissipating material and has an impact-dissipating member inner side and an impact-dissipating member outer side opposite the impact-dissipating member inner side. The memory foam member is in-moulded with the impact-dissipating member. Also, a process for forming a helmet by in-moulding a memory foam member and an impact-dissipating material together. The in-moulding process permanently binds the memory foam member outer side to the impact-dissipating member inner side.

Abstract: A thin-film solar cell contains: a lens material layer, a conductive contact layer, a first n-p semiconductor layer, a second n-p semiconductor layer, an insulation layer, a transparent conducting layer, a substrate, multiple first vias, multiple insulators, and multiple electrical conductors. A respective first via passes through the lens material layer, the conductive contact layer, and the first n-p semiconductor layer. The multiple insulators are accommodated in the respective first via, a top of a respective insulator is connected with the second n-p semiconductor layer, and a bottom of the respective insulator is connected with the insulation layer. The respective insulator includes a respective second via. A respective electrical conductor is formed in the respective second via, a top of the respective electrical conductor is connected with a respective transparent conducting layer, and a bottom of the respective electrical conductor is connected with the substrate.

Abstract: A helmet contains a convex, hard outer shell, a concave, impact-dissipating inner layer, a shield, and a shield cover. The concave, impact-dissipating inner layer is fitted to the convex, hard outer shell and contains a front portion having a shield indentation, a back portion, a top portion a right side portion, and a left side portion. The left side portion is opposite the right side portion. The shield is pivotably attached to the helmet via a fulcrum and pivots about the fulcrum. The shield also partially occludes the shield indentation. The shield cover is fixably attached to the helmet and at least partially occludes the front portion. The shield cover also at least partially occludes the shield.

Abstract: An improved bicycle helmet includes an inner layer having a concave shape, an outer layer having a convex shape, and a sun visor. The outer layer covers the inner layer and includes an outer layer attachment member and an outer layer lock member. The sun visor includes a shade member and a sun visor attachment member connected to and distal to the shade member. The sun visor attachment member is adapted to rotatably engage with the outer layer attachment member to form a fulcrum. The sun visor lock member is adapted to operatively engage the outer layer lock member so as to releasably lock the sun visor into a fixed position. The sun visor lock member and the outer layer lock member operatively engage so as to allow the sun visor to be releasably locked into one of a plurality of fixed positions. the sun visor attachment member and the outer layer attachment member rotatably engage via a snap fit fastener.

Abstract: A helmet(10) has a memory foam member(20) and an impact-dissipating member(26). The memory foam member(20) is formed from a memory foam material and the impact-dissipating member(26) is formed from an impact-dissipating material and has an impact-dissipating member inner side and an impact-dissipating member outer side opposite the impact-dissipating member inner side. The memory foam member(20) is in-moulded with the impact-dissipating member(26). Also, a process for forming a helmet(10) by in-moulding a memory foam member(20) and an impact-dissipating material together. The in-moulding process permanently binds the memory foam member outer side to the impact-dissipating member inner side.

Abstract: A helmet contains a convex, hard outer shell, a concave, impact-dissipating inner layer, a shield, and a shield cover. The concave, impact-dissipating inner layer is fitted to the convex, hard outer shell. The concave, impact-dissipating inner layer contains a front portion having a shield indentation, a back portion opposite the front portion, a top portion joining the front portion and the back portion, a right side portion joining the front portion, the back portion, and the top portion, and a left side portion joining the front portion, the back portion, and the top portion.

Abstract: A ratchet paw module structure is disclosed.

Abstract: A ratchet paw module structure is disclosed. The module comprises a ratchet block seat and a ratchet seat, the ratchet block seat including a ratchet block module and the ratchet seat having a series of ratchet teeth corresponding to the ratchet paw module allowing the ratchet seat to engage or disengage correspondingly, characterized in that the ratchet block seat includes at least two groups of ratchet block modules, and each of the ratchet blocks of the ratchet block module have a distance, and the ratchet block is positioned in adjacent to the ratchet block module and the engaging position of the ratchet teeth on the ratchet seat is displaced eccentrically within the range of one ratchet teeth width; whereby when the ratchet block engages the ratchet teeth, the subsequent ratchet block is displaced eccentrically within the range of the ratchet teeth to minimize the reverse distance of rotation.

Abstract: An adjustable register includes a frame member having an air passage therethrough, a plurality of slats connected pivotally to the frame member, a slat connecting member connected to each of the slate a slat-controlling linkage connected pivotally to one of the slats, a toggle-joint mechanism connected pivotally to the slat-controlling linkage on the frame member, and a plurality of blocking bars on the frame member. As the toggle-joint mechanism is operated, the slat-controlling linkage is driven to drive one of the slats. All slats move concurrently between a closed position where the slats contact closely the blocking bars, and an open position where the slats allow air flow through the air passage. In the closed position, the air-tight effect of the register is ensured.
