摘要： A vision system is provided to determine a positional relationship between a semiconductor wafer on a platen and an element on a processing machine, such as a printing screen, on a remote side of the semiconductor wafer from the platen. A source directs infrared light through an aperture in the platen to illuminate the semiconductor wafer and cast a shadow onto the element adjacent an edge of the semiconductor wafer. A video camera produces an image using light received from the platen aperture, wherein some of that received light was reflected by the wafer. The edge of the semiconductor wafer in the image is well defined by a dark/light transition.

摘要： A system and method for automated determination of position and movement of a contact lens with respect to a subject wearer's eye based upon a complimentary pair of images, acquired in rapid succession, in which one image of the pair is acquired using light that allows viewing of the pupil and/or limbus through the lens and the other image is acquired using light that is absorbed by the lens to generate an opaque image with a defined edge relative to the surrounding sclera. The images of the pair are acquired in close enough temporal proximity to ensure that eye movement in the interval therebetween is insignificant and both images are in the same approximate reference frame. Thus, the location of the pupil and limbus in one image can be accurately compared with the location of the contact lens edge in the other image.

摘要： A slow release apparatus for slowly releasing a compound in a nasal passage. The apparatus comprises a connection mechanism, two expansion mechanisms, and two release mechanisms; two ends of the connection mechanism are respectively integrally or detachably connected to the two expansion mechanisms that are symmetrically arranged in nasal passages at two sides; and the two release mechanisms are symmetrically arranged, and each release mechanism is correspondingly provided in one of the expansion mechanisms. The slow release apparatus is convenient to carry, and capable of slowly releasing a compound in the nasal passage and synchronously expanding the nasal passage to ensure smooth breathing, while considering functionality, practicability and comfort.
