Abstract: A method for recognizing arteries and veins on a fundus image includes: executing a pre-process operation on the fundus image, so as to obtain a pre-processed fundus image; generating a fundus spectral reflection dataset associated with pixels of the pre-processed fundus image, based on the pre-processed fundus image, and a spectral transformation matrix; obtaining a plurality of principle component scores associated with the pixels of the pre-processed fundus image, respectively; and determining, for each of the pixels of the pre-processed fundus image that has been determined as a part of a blood vessel, whether the pixel belongs to a part of an artery or a part of a vein.

Abstract: A method is provided to make a bipolar plate of a flow cell. The two insulating frames traditionally cladding the graphite plate is changed. Through injection-molding, an acid-resisting insulating material is molded on the graphite plate to form an integrated bipolar plate. Composite channels are designed around the graphite plate. Thus, the binding force between the acid-resisting insulating material and the graphite plate is increased and the risk of electrolyte leakage is reduced. In order to reduce shunt currents, branch channels are also made in the frame through injection-molding. By using the bipolar plate thus made accordingly, not only the possibility of electrolyte leakage but also the number of components and the time for processing assembly can be significantly reduced. The cost of processing and assembly is effectively decreased. Accordingly, the present invention simplifies the structure of bipolar plate with cost reduced.

Abstract: A bezel assembly includes a bezel, a button, a rotating member, and an elastic member engagable with the bezel and the rotating member for restoring the rotating member. The bezel defines a through hole therein, and the button is installed in the through hole. The rotating member is mounted to an inside surface of the bezel, and the rotating member is engagable with the button and rotatable upon manipulation of the button for controlling a functional component behind the bezel.
