Abstract: Distance measuring is disclosed. In one example, a distance measuring device includes a ToF (time of flight) sensor, a distance calculation unit, a mode switching unit, and an estimation unit. The ToF sensor has a sensor clock that controls a photographing timing. The sensor clock is a device-specific clock different from a light source clock that controls a modulation frequency of a light emission pulse of a light source. The ToF sensor performs photographing by reflecting, on a surface of an object, emission light of the light source that emits pulse light. The distance calculation unit calculates a distance to the object based on image data captured by the ToF sensor. The estimation unit estimates the modulation frequency of the light source generated from the light source clock based on pieces of image data captured in an operation mode switched by the mode switching unit.

Abstract: A cross-section of a main shaft of a photovoltaic tracking support is of a compact cross-section. This cross-section includes four planar segments and four arc segments. The four planar segments and the four arc segments are alternately arranged circumferentially to form a square tubular structure. Widths of the four planar segments are equal, and radians of the four arc segments are also equal, making the square tubular structure formed by the four planar segments and the four arc segments centrally symmetric about an axis of the main shaft. A ratio of the width x? of the planar segment to a wall thickness t of the main shaft, i.e., a width-to-thickness ratio x?/t, falls within a range of 20 to 25, which achieves a balance and compromise between torsional strength and bending strength, thereby providing better stability.
