摘要： An uninterruptible power supply (UPS) system and control method thereof is provided. The system contains a plurality of UPS modules connected in parallel, and each module is equipped with full uninterruptible power supply capabilities, and redundant control logic and functional capabilities for self-initiated role detection, master arbitration and parallel processing. The UPS system is self-initialized through a master arbitration process to elect a virtual master among the peers for maintaining inter-unit signaling between parallel UPS modules and controlling the parallel operation. If the virtual master is failed, other UPS modules will initiate the role detection and master arbitration to re-elect a new virtual master. Parallel operation is accomplished without any external controller; the system can be operated with only one UPS module; distribution of adequate resource to each module is properly arranged, thus the risks of system-level single-point failure are much reduced.

摘要： A modular AC power supply system with fault bypass and the method of switching output modes is provided. The system architecture allows a plurality of uninterruptible power supply (UPS) modules connected in parallel to share the loads and tripped for fail independently. A virtual control center is automatically installed in one of the UPS modules at system initialization, used for controlling all UPS modules connected over the UPS network. When a disorder is detected in any UPS module, the virtual control center first collects the operation data from other parallel UPS modules through a high speed communication line, and then decides to send a command to the failing module to trip and shutdown, or to send a command to all parallel UPS modules to switch to the bypass mode through a high speed communication line. The system also employs a low priority interrupt with the falling edge of sync clocks to enhance the overall system reliability and the usage of system resources.

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.
