Patent number: 9197790Abstract: An optical scanning projection module includes a scanning light component including a plurality of sub light sources and at least one light-splitting element, a main light reflective element, a scanning element and a photosensitive element. Sub light beams of the sub light sources are converged to form a main light beam. One of the sub light beams travels to the light-delivering element to form a partial reflective light beam and a partial penetrating light beam. With a scanning manner, the partial reflective light beam or the partial penetrating light beam is reflected by the scanning element to be an inspection light, and the main light beam is reflected by the scanning element to be a projection light. The photosensitive element outputs a sensing signal according to the inspection light. Thus, the optical scanning projection module controls the operation of the scanning light component according to the sensing signal.Type: GrantFiled: January 3, 2013Date of Patent: November 24, 2015Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Ming-Chieh Chou, Han-Wei Su, Yao-Hui Lee, Yu-Jen Wang

Patent number: 7731003Abstract: An axially actuating device having an elastic joining portion is provided, which is used for carrying an object and actuating the object to move axially, and comprises a fixed portion, a moving portion, and a joining member. The joining member is used to combine the fixed portion with the moving portion, such that the fixed portion and the moving portion are axially coupled with each other. Moreover, the fixed portion and the moving portion are respectively a fixed magnet and a coil, such that when a current is applied to the moving portion, the moving portion generates a relative displacement with respect to the fixed portion according to the current, so as to provide an axial displacement. Meanwhile, the moving energy is generated due to the repulsive interaction of the magnetic field, and thus a shock proofing efficacy is also provided.Type: GrantFiled: December 12, 2006Date of Patent: June 8, 2010Assignee: Industrial Technology Research InstituteInventors: Han-Wei Su, Wen-I Wu, Chao-Chang Hu, Yu-Han Chien
