Abstract: The invention provides a method for eliminating the noise of an optical switch, wherein the optical switch includes a cantilever, a flexible coupler and a joint. The joint is designed to connect the cantilever and the flexible coupler so as to perform a phase conversion by the cantilever. The method for eliminating the noise of the optical switch includes a step of damping generation so that the vibration of the cantilever can be eliminated during the phase conversion.

Abstract: A magnetic flux detection apparatus and a system with the magnetic flux detection apparatus are provided. The magnetic flux detection apparatus includes the magnetic material, at least one heated or cooled magneto caloric effect material (MCEM), a permanent magnetic element, at least one magnetic sensing element, and at least one amount of magnetic flux or magnetic flux path. The heated or cooled magneto caloric effect material is disposed to the magnetic material. The amount of magnetic flux or magnetic flux path is formed and passing through the permanent magnetic element, the cooled magneto caloric effect material, and the first portion of the magnetic material. A magnetic sensing element senses the amount of the magnetic flux or the magnetic flux path for outputting a sensing voltage and a corresponding sensing voltage value so as to apply the best thermal energy-applying algorithm into the magnetic system to output power efficiently.

Abstract: An optical shutter for a projection system includes a shutter element and an actuator. The shutter element includes a light-shielding portion and a linkage portion. The light-shielding portion is disposed on the optical pathway of the projection system and is connected with the linkage portion. The light-shielding portion is bent toward the linkage portion and there is a pre-determined angle formed between the light-shielding portion and the linkage portion. The light-shielding portion faces the linkage portion with a predetermined angle. The actuator is coupled with the linkage portion to drive the shutter to swing.
