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: A backlight module includes a light source, a first prism sheet disposed on the light source, and a light type adjustment sheet disposed on a side of the first prism sheet away from the light source and including a base and multiple light type adjustment structures. The multiple light type adjustment structures are disposed on the first surface of the base. Each light type adjustment structure has a first structure surface and a second structure surface connected to each other.

The angle of the first base angle is different from the angle of the second base angle.

Abstract: A clock de-skewing delay locked loop circuit is revealed. In the clock de-skewing delay locked loop circuit, a timing control circuit generates a first and a second clock signals according to an external and an internal clock signal. A clock delay line delays the first clock signal or the external clock signal to generate delay signals. A delay mirror circuit synchronizes the internal clock signal with the external clock signal. A phase adjustment circuit inverts the internal clock signal according to the phase difference. An inverting buffer circuit buffers the external clock signal or the first clock signal for adding an initial delay time so as to make a duty cycle of internal clock signal and of the external clock signal complement each other. Thus the duty cycle of the external clock signal in the proposed circuit is not necessarily 50%.

Abstract: The present invention discloses an ocular-protection projector device, wherein the projector is additionally equipped with an image-capture unit. When the projector projects information onto a screen, the image-capture unit captures the human-shape image of a user. An image-processing unit, which is arranged inside the projector or an external electronic device, receives the human-shape image, creates a human-shape black mask, and outputs the human-shape black mask via the projector onto an area of the screen corresponding to the user's position. Thereby, the present invention can effectively protect the user's eyes from the harm of intense light.
