摘要： The present invention discloses an optical system with multiple optical lens having capability of auto-focus calibration, instead of conventional scheme of manual operations. Furthermore, achieve purpose of obtaining more accuracy in sharpness and magnification calibration than the conventionally scheme, and of upgrading yield rate of the system. The optical system disclosed by the invention basically includes a lot of home-sensors and micro-sensors, lots of lens, an image sensor, an imaging control motor, a lens switch motor for switching the lens, and a base control motor for switching base of the optical system. By using the imaging control motor and the base control motor to control motions of the imaging device and the lens, auto sharpness and magnification calibration is easily achieved.

摘要： A lens switching apparatus for a dual-lens optical scanner includes a base, a plurality of magnetic elements, a plurality of electromagnetic elements, a guiding assembly and a slide block. Two optical lens with different magnification are mounted on the slide block. The slide block may be moved and positioned in one direction when one of the electromagnetic element attracting one adjacent magnetic element while another electromagnetic element repulsive another adjacent magnetic element. The dual-lens mounted on the slide block thus can be switched as desired for scanning process.

摘要： An improvement of transparent window glass holding structure for an optical scanner includes a first rack fixedly disposed in the case. The first rack has a plural number of clamps for holding and gripping the transparent window glass securely without gluing the originals table to the case as does a conventional scanner. The originals table can be easily installed and removed to facilitate the repairs and maintenance of the scanner.

摘要： A first polymer is coated with a second polymer by placing the polymers separately in the barrels of a double-barrelled extruder, and extruding the polymers through a common orifice into a coagulation solution. For example, a core of an absorbent, thermoplastic polyurethane hydrogel can be coated with gelatin to form an absorbent fiber.

摘要： A two component interpenetrating polymer network (IPN) wound dressing material is formed of a biocompatible, hydrophilic first component such as gelatin or polyvinyl alcohol and a biocompatible elastomer such as HydroThane (trademark) by dissolving the components in a common solvent, initiating cross-linking of at least one of the components in the solution, and forming a film, fiber, bead or mesh from the solution. When the first component is a methacrylated gelatin aged for an extended period, e.g. 1 to 8 weeks, the resulting IPN is more stable with a higher tensile strength. Heating of the methacrylated gelatin during aging and/or freeze-drying of the product also increase tensile strength of the product.
