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.

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 system and method for generating golden template images in a vision system to inspect an acquired runtime image of an object with a multi-layer printed pattern is provided. The system and method performs a registration process on runtime images using registration models each trained on respective canonical layer mask images, and outputting poses. Based upon the poses, warped layer masks are generated. Combination masks are computed based upon differing combinations of the warped layer masks. Intensity values for pixels of the foreground regions for the combination masks are estimated. The estimated intensity values are then blended associated with the combination masks to generate a golden template image. This golden template image can be used to compare with a runtime image. An exemplary application of this system and method is in print inspection on flat and non-flat surfaces.
