摘要： A radio frequency (RF) positioning system comprises transceivers, positioning tags, processing units and a computing host. One or multiple positioning tags are attached to a target object being located. When the transceivers first generate and transmit transmission signals, one or multiple tag antennas in the positioning tag receive the transmission signals and transmit back modulated signals. The transceivers then receive and transmit the modulated signals to the processing units. The processing units are configured to obtain received signals, and calculate frequency differences based on the received signals and the transmission signals. The computing host calculates position coordinates of tag antennas based on the frequency differences, and then calculates the orientation of the target object being located according to the position coordinates of the tag antennas.

摘要： A system for register operating space includes a first positioning mark, a local camera, a second positioning mark, a global camera and a computer system. The first positioning mark is set on a patient. The local camera captures a first image covering the first positioning mark. The second positioning mark is disposed on the local camera. The global camera captures a second image covering the second positioning mark. The focal length of the global camera is shorter than the focal length of the local camera. The computer system is communicatively connected to the local camera and the global camera to provide a navigation interface based on the first image and the second image.

摘要： A ceramic surface treatment method includes the following steps. An antibacterial ion and a sol-gel solution containing a silane compound are mixed to form a treatment solution. Next, a ceramic substrate is placed in the treatment solution to perform a treatment bonding reaction such that the antibacterial ion in the treatment solution can be grafted to the surface of the ceramic substrate via the silane compound. Next, a sintering condensation reaction is performed on the ceramic substrate after the treatment bonding reaction to form a protective film on the surface of the ceramic substrate. The protective film is attached to the surface of the ceramic substrate via a hydrophobic layer, and the antibacterial ion is spread on the hydrophobic layer.

摘要： A system for registering operating space includes a back bracing, a computer system and a robotic arm. The back bracing includes positioning marks which can be imaged in a computer tomography (CT) image, and the back bracing is used to be worn by a patient. The computer system computes image coordinates of the positioning marks in an image space. A base of the robotic arm is connected to the back bracing in an operating space after the CT image is generated. The robotic arm contacts the positioning marks in the operating space and meanwhile the computer system obtains arm coordinates of the robotic arm in an arm space. The computer system generates conversion models among the image space, the operating space, and the robot arm space according to the image coordinates and the arm coordinates.
