Abstract: Motor control architecture including a travel, a hoist, and a controller is disclosed. The travel disposed on a main rail having an auxiliary-encoder includes a master-driver and a slave-driver for driving two motors. Each motor has a main-encoder. The hoist drives a rope and calculates a rope length continuously. The controller calculates an anti-sway position command based on the rope-length and a position command. The two drivers perform a full closed-loop computation based on a feedback of one main-encoder, a feedback of the auxiliary-encoder, and the anti-sway position command. Wherein, the master-driver controls one motor based on a speed command generated by the full closed-loop computation and the slave-driver follows the speed command and a torque command of the master-driver to drive another motor; or the two drivers compensate the torque command based on an error value between the feedback of one main-encoder and the feedback of the auxiliary-encoder.

Abstract: An electronic device includes a light emitting layer, a light conversion layer and an adjustable structure. The light emitting layer has a plurality of light emitting units for emitting light. The light conversion layer converts the wavelength of the light emitted by at least one light emitting unit to provide converted light. The adjustable structure is controlled to adjust a light penetrating area to correspond to the affected part to be treated, wherein at least one of the light and the converted light passes through the light penetrating area to irradiate the affected part.

Abstract: A method of applying a riblet structure coating on the internal surface of a pipe includes coating the internal surface of a pipe with a resin layer and applying a cavity mold having a reverse riblet pattern structure to the coated internal surface of the pipe. A flexible air bag is inserted into the interior of the pipe and charged with air to hold the mold against the coated internal surface of the pipe. The air bag may be charged with air for a sufficient amount of time to allow the coating to cure in the riblet shape of the mold. Afterwards, the air bag and the mold are removed from the pipe to yield a pipe coated with an internal riblet structure.
