  • Patent number: 11975296
    Abstract: A pore-filled ion exchange polyelectrolyte composite membrane from which the surface ion exchange polyelectrolyte has been removed and a method of manufacturing the same are provided. The ion exchange polyelectrolyte composite membrane exhibits low film resistance and low in-plane-direction swelling degree, and has a smaller film-thickness than a commercial film, and thus, can be used for various purposes. In addition, since the pore-filled ion exchange polyelectrolyte composite membrane is continuously manufactured through a roll-to-roll process, the manufacturing process is simple, and manufacturing costs can be greatly reduced.

  • Patent number: 8855732
    Abstract: In a non-invasive human metabolic condition measuring apparatus and method, a micro-light source emits an incident light having a wavelength from 329 nm to 473 nm to trigger a mitochondrial metabolite of a human mucosa tissue, and the metabolite is excited to generate a fluorescent signal having a wavelength from 405 nm to 572 nm, and the fluorescent signal is filtered by an optical filter, received by a micro receiver, and amplified by an amplification circuit sequentially, and then a filter circuit and an analog/digital conversion circuit of a microprocessing unit are provided for filtering and performing an analog/digital signal conversion respectively, so that the metabolite content can be calculated by the computation to provide human metabolic conditions, and a combination of micro components and circuits is used for miniaturizing the apparatus to provide a convenient carry of the apparatus.

  • Publication number: 20050036320
    Abstract: An apparatus for manufacturing a surface light source apparatus in which a light guide pattern portion is formed on a light guide panel includes a pattern design system to which data about a pattern to be formed on the light guide pattern is input. A control system is connected to the pattern design system and transmits a position signal matching a coordinate value of each pattern to be formed on the light guide panel. A header moving portion mechanically moves vertically and horizontally according to the position signal received from the control system. A laser system outputs a laser beam according to a pulse signal synchronized with a movement of the header moving portion. A lens portion allows a laser beam output from the laser system to pass the header moving portion and to be focused on a scanning surface of the light guide panel. A warp prevention unit prevents the light guide panel from warping due to a local heating by the laser beam.
