Patent number: 10618534Abstract: A monitor vehicle for a rail system includes a wheeled trolley, an overhead vehicle, a supporting structure, and a first sensor. The wheeled trolley is above a rail of the rail system, is operable to move over the rail, and has a bottom surface. The overhead vehicle body is suspended by the wheeled trolley and below the rail. The supporting structure connects the wheeled trolley and the overhead vehicle body. The first sensor is on the bottom surface of the wheeled trolley and is configured to detect a first parameter of the rail of the rail system.Type: GrantFiled: November 4, 2019Date of Patent: April 14, 2020Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventors: Shih-Hung Chien, Jen-Ti Wang, Fu-Hsien Li, Chih-Hung Liu, Yung-Lin Hsu

Patent number: 9891103Abstract: A spectrometer comprising a waveguide module, a diffractive component, and a light sensor is provided. The waveguide module has a first reflective surface, a second reflective surface opposite to the first reflective surface, and a light channel between the first reflective surface and the second reflective surface. The diffractive component has a diffractive surface and a plurality of strip-shaped diffractive structures located on the diffractive surface. The sharpness of the profile of the strip-shaped diffractive structures on a first side of the diffractive surface is greater than that on a second side of the diffractive surface. When viewed along a direction perpendicular to the second reflective surface, the first side of the diffractive surface is positioned between the first reflective surface and the second reflective surface with a distance away from the second reflective surface. A method for assembling the spectrometer and an assembling system are also provided.Type: GrantFiled: January 21, 2016Date of Patent: February 13, 2018Assignee: OTO PHOTONICS INC.Inventors: Meng-Hua Wang, Shih-Hung Chien, Jyh-Jau Chen, Jan Liang Yeh

Patent number: 7283685Abstract: The invention provides a device that appends a recognition point for image joining to the extracted image and a recognition element thereof. The device is to provide a plurality of holding slots on a holding platform. Besides, a plurality of positioning slots is provided at the sidewall of each holding slot so that the holding slot can accommodate and fasten an object to be image-taken. Then, when the image of the object is extracted by the segmented extractions, the image of the positioning slot can also be extracted so as to obtain an image with a recognition mark. Thus, the recognition mark can be used as a benchmark for image joining in order to obtain a whole image of the object. Moreover, the recognition element is to provide a positioning opening concavely at the side edge of a sheet-body, and the positioning opening is tiny. Therefore, the invention can achieve an effect of easy, rapid, and precise image joining.Type: GrantFiled: September 23, 2003Date of Patent: October 16, 2007Assignee: Microtek International Inc.Inventors: Shih-Hung Chien, Ping-Jung Fan
