    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 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 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 ultraviolet 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 motor with a variable-speed torque converter is disclosed. A rotor of the motor has a common permanent magnet structure. Permanent magnets are disposed on the rotor. The variable-speed torque converter includes a wheel disc, a wheel ring, a roller, a transmission gear II, a transmission gear III, a round wheel, an annular gear, a driving gear, turning discs, a transmission shaft, and an output shaft. The driving gear fixedly connected to the transmission shaft of the motor drives the transmission gear. The transmission gear is in contact with the annular gear. The transmission gear rotates around the driving gear to drive the wheel disc to rotate together. The wheel disc is fixedly connected to the output shaft to drive a driving wheel to rotate. Therefore, a working capability of the motor is enhanced. The converter can be applied to an electromotor, a generator, or any other power device.
