Abstract: There is provided eyeglasses with adjustable light penetration including two lenses, a power source and a control device. The two lenses respectively include two electrodes and a liquid crystal layer sandwiched between the two electrodes. The power source is electrically coupled to the two electrodes of the two lenses through the control device. The control device is configured to control an electrical signal provided from the power source to the two electrodes thereby adjusting a light penetration rate of the liquid crystal layer.

Abstract: The present disclosure is related to an optical encoder which is configured to provide precise coding reference data by feature recognition technology. To apply the present disclosure, it is not necessary to provide particular dense patterns on a working surface. The precise coding reference data can be generated by detecting surface features of the working surface.
