    • In an apparatus and method for receiving light using multiple light receiving sensors, a light receiving apparatus includes a light receiving unit comprising multiple light receiving sensors to receive an optical signal; an analyzing unit to extract a highlighted area; a light receiving controlling unit to activate a first light receiving sensor corresponding to the highlighted area, and to determine the first light receiving sensor to be a part of a first sensor group; and a data processing unit to demodulate an optical signal received by the first sensor group into data. A method for receiving an optical signal including extracting a highlighted area; activating a light receiving sensor corresponding to the highlighted area; receiving light through the first light receiving sensor; grouping the first light receiving sensor into a first sensor group; and demodulating an optical signal received by the first sensor group into data.

    • A hand truck includes a frame body and a wheel assembly including two wheel units spacedly supported at the frame body to switch between a first operation position and a second operation position for enabling the frame body to be tilted backward to transport a load. At the first operation position, the wheel units are switched in parallel for enabling the frame body to move at a back-and-forth direction, and at the second operation position, the wheel units are switched to align with each other for enabling the frame body to move at a left-and-right direction. Therefore, the hand truck provides two modes of movement for a two-dimensional movement.
    • 手推车包括框架体和车轮组件,其包括两个轮单元,两个轮单元间隔地支撑在框架体上,以在第一操作位置和第二操作位置之间切换,以使框架体能够向后倾斜以输送负载。 在第一操作位置,车轮单元被平行切换以使框架体能够在前后方向上移动,并且在第二操作位置,车轮单元被切换成彼此对准以使框架 身体在左右方向移动。 因此,手推车为二维运动提供两种运动模式。
