Abstract: The present invention provides a power generation device for exercise equipment including a fixing seat, a swinging seat and a power generating component. The joint and positioning end of the swinging seat has a hinge connection part to be connected with the fixing seat, and the power generating component is configured on a preset position on the swinging seat. A magnetic lifting component is configured to cause magnetic repelling between the swinging end of the swinging seat and the fixing seat, so that the swinging end of the swinging seat can be elastically lifted. The driven part of the power generating component will constantly maintain tight contact with the flywheel of exercise equipment. The magnetic lifting component can exert a magnetic repulsing function without elastic fatigue and solid abrasion.

Abstract: A microfibrous fuel cell structure of elongated form with a longitudinal axis. Such microfibrous fuel cell includes electrocatalyst layers supported by a fiber network formed of unidirectional or substantially unidirectional conductive fibers. The conductive fibers of such fiber network are oriented parallelly or substantially parallelly to the longitudinal axis of the fuel cell, therefore allowing such fiber network to conform to the curvature of the microfibrous fuel cell along the radial direction but without causing overbending of the individual fibers.

Abstract: The present invention relates to a gas storage and dispensing system, which comprising a carrier material for a target gas and multiple microtubular elements in contact with such carrier material. Each microtubular element comprises a tubular wall that defines a bore side and a shell side that are sealed from each other, preferably by one or more potting members. The carrier material is either at the bore sides or at the shell sides of the microtubular elements, and it can be either a solid sorbent material for the target gas, or a liquid carrier therefor. Such gas storage and dispensing system is particular useful for hydrogen storage, when the carrier material can be a hydrogen-sorbent that contains hydrogen gas, or liquefied hydrogen, or an organic hydrogen solution, or a metal hydride solution capable of generating hydrogen gas. Such microtubular elements can further be designed as microfibrous fuel cells, while each microfibrous fuel cell comprises a carrier material at its bore side.

Abstract: An image reading device is activated by the light interference of a light path. The image reading device comprises at least an image sensing element, a picture and an image changing mechanism such as a picture conveying module, picture rotating module, a hole or a soft button with a picture in the inner side. The user may use a finger or other objects to interfere with the image generated in the image sensing element. By detecting the changes of the image, a predetermined activation process of the image reading device is therefore started.

Abstract: A process for the delacquering and detinning of a metal substrate is presented comprising the fully electrochemical removal of both an outer polymeric coating and an inner tin coating from a metal substrate. The disclosed method provides a clean metal substrate, and results in wastes which are easily disposed of with minimal cost and minimal environmental impact. In one embodiment, the present invention comprises a one-stage process for removing an outer polymeric coating and an inner tin coating from a metal substrate in a single electrolyte bath through electrolytic removal of both the polymeric and tin layers from the metal substrate. An electrically conductive container having the electrolyte bath therein acts as an anode in the process, and the removed tin is plated out on the cathode. In another embodiment, the present invention comprises a two-stage process for removing an outer polymeric coating and an inner tin coating from a metal substrate.
