Abstract: A system includes an image capturing device, a subject reference marker disposed adjacent to a subject, a tool reference marker disposed on a treatment tool, a display device mounted on an operator, an operator reference marker disposed on the display device, and a processor. The image capturing device includes two image capturing modules that simultaneously and respectively capture two images of the operator, the subject, and the treatment tool. The processor receives the images, analyzes the images to obtain spatial locations of the reference markers, and transmits coordinate information and auxiliary information.

Abstract: In a proposed surgical navigation method for a surgical operation to be performed on an operation target, a mobile device stores 3D imaging information that relates to the operation target before the surgical operation. Then, an optical positioning system is used to acquire spatial coordinate information relating to the mobile device and the operation target, so that the mobile device can obtain a relative coordinate which is a vector from the operation target to the mobile device, obtain a 3D image based on the relative coordinate and the 3D imaging information, and display the 3D image based on the relative coordinate, such that visual perception of the operation target through the mobile device has the 3D image superimposed thereon.

Abstract: A Universal Serial Bus (USB) controller with a VIDS pin to set up a plurality of vendor identification which can be accompanied with interface and software program. Thus, one chip can achieve Vendor ID/Product ID (VID/PID) of 2N types (N is a positive integer equal to or greater than 1) in accordance with various USB manufactures and products.
