Abstract: The present disclosure relates to a belt driven system. The belt driven system may include a master pulley, a slave pulley, a belt around the master pulley and the slave pulley, a tension pulley configured to tension the belt, and a position adjusting device configured to automatically adjust a position of the tension pulley based on an interaction of the tension pulley and the belt.

Abstract: The present disclosure provides a method for adjusting a position of a photosensitive chip of an image acquisition device. The method may include determining a first symmetrical axis and a second symmetrical axis of the photosensitive chip. The first symmetrical axis may divide the photosensitive chip into a first portion and a second portion, and the second symmetrical axis may divide the photosensitive chip into a third portion and a fourth portion. The method may further include adjusting the position of the photosensitive chip from an initial position to an adjusted position. When the photosensitive chip is at the adjusted position, a first image resolution corresponding to the first portion may be substantially equal to a second image resolution corresponding to the second portion, and a third image resolution corresponding to the third portion may be substantially equal to a fourth image resolution corresponding to the fourth portion.

Abstract: The present disclosure relates to a stand. The stand may include a supporting component, a rotation component, a rotation limiting component, and an adapter ring. The rotation component may be rotatably connected to the supporting component and may be configured to rotate about a first rotation axis. The adapter ring may be placed between the rotation component and the rotation limiting component. The rotation component may include first ratchet teeth on a first side of the rotation component. The rotation limiting component may include second ratchet teeth on a second side of the rotation limiting component facing the first side. The adapter ring may include third ratchet teeth and fourth ratchet teeth on a third side and a fourth side of the adapter ring, respectively. The third ratchet teeth may be engaged with the first ratchet teeth and the fourth ratchet teeth may be engaged with the second ratchet teeth.
