  • SYSTEM AND METHOD FOR TREATING ENDS OF OPTICAL FIBERS FOR USE IN AN ENDOSCOPE
    Publication number: 20220197008
    Abstract: Treated ends of optical fibers for use in an endoscope are disclosed. An end of an optical fiber, either raw cut or polished, is coated with an optical material that enables the end to be aligned without the need for conventional flush mounting techniques.

  • SYSTEM AND METHOD FOR TREATING THE END OF AN OPTICAL FIBER BUNDLE TO REDUCE LIGHT REFLECTION
    Publication number: 20210405293
    Abstract: A system and method for treating the end of an optical fiber bundle to reduce light scattering/reflection is provided. After the end of the optical fiber bundle is formed, it has a raw end. A material is applied to the raw end to form a treated end that provides a substantially smoother surface then the raw cut end, which reduces the amount of light rays reflected from the end.

  • Program event recorder and data processing system
    Patent number: 3931611
    Abstract: Disclosed is a method and apparatus for program event recording in a data processing system and is used, for example, in debugging programs. A program event occurs whenever an address in the data processing system falls within a range between a control lower address (DTCL) and a control upper address (DTCU). The system detects a program event without degrading system performance using carry-lookahead adder structures which implement four inequality relationships.
