  • Patent number: 10399851
    Abstract: A master tool is provided with an ink pattern on a major surface thereof. The ink pattern is formed by a screen printing process. A stamp-making material is applied to the major surface of the master tool to form a stamp having a stamping pattern being negative to the ink pattern of the master tool. The stamping pattern is inked with an ink composition and contacted with a metalized surface to form a printed pattern on a metalized surface of a substrate according to the stamping pattern. Using the printed pattern as an etching mask, the metalized surface is etched to form electrically conductive traces on the substrate.

  • Publication number: 20170156571
    Abstract: An ultrathin endoscope auxiliary system includes an overtube (110) and a mouth piece (150). The overtube (110), which allows the ultrathin endoscope (160) to be inserted therein, includes a transparent cap (112), a side opening (114), a deflecting member (180) and a positioning member (120). The transparent cap (112) is disposed at the front end of the overtube (110); the side opening (114) is disposed on the overtube (110) and approximates to the front end of the overtube (110); whereas the deflecting member (180) is disposed within the overtube (110) and the positioning member (120) is disposed outside the overtube (110) and approximates to the side opening (114). The deflecting member (180) is capable of deflecting the ultrathin endoscope and thereby allows the ultrathin endoscope (160) to be extended outside the overtube (110) through the side opening (114). The mouth piece (150) works with the overtube (110) to adjust the length and the axial orientation of the overtube (110) in the subject.

  • Patent number: 9572545
    Abstract: The present invention provides a radiotherapy system that can monitor a target location in real time. The radiotherapy system includes a remote control system operable to actuate a real-time image capturing device to acquire images in real time for monitoring the target location. The system also includes an image registration system that can register the acquired image with an image previously captured for the treatment plan, whereby it can be determined whether the patient's tumor is in the beam's eye view of the treatment plan. By confirming that the tumor is in the range of the beam's eye view, the accuracy of the treatment can be improved, and the irradiated area can be reduced, which makes the radiation treatment safer.
