A lens measuring device and method applied therein. The lens measuring device includes a light source, a first polarizer, a second polarizer, and an image analysis module. The method includes enabling the light source to orderly pass through the first polarizer, a lens to be measured, and the second polarizer to generate a light beam to be measured, and then enabling the image analysis module to analyze image-related information of the light beam to be measured, consequently deducing the structural center and energy distribution of the lens to be measured, and then further analyzing errors in polarity and skewness of the lens to be measured. By applying a common light source, the method is spared complicated correction that is otherwise required when a conventional collimating laser light source is applied, and the method can also easily and simultaneously test a plurality of lenses to be measured.

Lens measuring device and method applied therein

An artificial sphincter system having: (1) a hollow object, which has the ability of contraction and expansion; (2) a shape memory alloy (SMA), which is connected with the hollow object, changes its shape to imitate the motion of human muscle by applying different electric current; (3) an electric power to provide different amounts of electric current to the shape memory alloy and let it contract or expand to control the motion of the hollow object to imitate the motion of human muscle; and (4) a photo resistor added between the electric power and the shape memory alloy, which senses the brightness of surrounding light and controls A/D (analog-to-digital) values of the electric power to cause different conditions of contraction and expansion of each part of the shape memory alloy.
