Abstract: A passive compliance mechanism includes a fixing member, a base and a stiffness adjustment assembly. The base is installed on the fixing member, and includes two notches and an elastic slice. A first end of the elastic slice is connected with the base. A second end of the elastic slice is located near the outer periphery of the fixing member. The stiffness adjustment assembly includes a linear guide, a sliding block and two stopping blocks. The linear guide is installed on the fixing member. The sliding block is movably installed on the linear guide. The two stopping blocks are disposed on the sliding block and synchronously moved with the sliding block. The two stopping blocks are contacted with two opposite sides of the elastic slice to clamp the elastic slice. A stiffness of the base is adjustable according to a clamped position of the elastic slice.

Abstract: An illuminating and air-conditioning assembly composed of a lampshade, an illuminating unit, and a ventilating unit. The lampshade is provided with a receiving space. The illuminating unit is mounted to the receiving space. The ventilating unit is also mounted to the receiving space. Therefore, illuminating and air-conditioning assembly includes the double features of illumination and auxiliary air-conditioning, takes less internal space, and enhances the comfort of the people located below the lampshade.

Abstract: A ceiling fan includes a mounting unit for fastening to a ceiling, a power unit, which has a motor fastened to the mounting unit and a fan member coupled to and rotatable by the motor, and a shade, which is fastened to the mounting unit to accommodate therein the power unit so as to kept the power unit from sight. The shade has a plurality of slots for guiding air flow induced by the fan member out of the shade.

Abstract: A direct-type backlight module with photo sensors has a plurality of lamps, a plurality of the photo sensors for detecting illumination of corresponding lamps, a comparative and arithmetic unit for processing signals generated by the photo sensors, and a main lamp driving loop for receiving feedback signals generated by the comparative and arithmetic unit and adjusting a lamp current voltage outputted by a minor lamp driving loop of each lamp, so as to achieve an uniform illumination of each lamp.

Abstract: A ceiling fan includes a connecting rod assembly, a motor, a housing, a cover shell, and a vane assembly. The connecting rod assembly includes a fixing seat secured to a ceiling and a connecting rod suspended beneath the fixing seat. The motor is mounted beneath the connecting rod. The housing encases the motor and is rotatable by the motor with respect to the connecting rod assembly. The cover shell is semi-spherical and is secured beneath the housing. The vane assembly is connected with the cover shell and includes a plurality of vanes and vane brackets. Accordingly, the ceiling fan is provided with a preferably centralized mass at its rotation circle to enhance the rotation stability and the whole model design and to reduce the production cost.
