The modern laparoscope relies on Hopkins’ glass rod lenses, a fiber-optic light source, a video camera, and external cables. This paper discusses the feasibility of developing an experimental prototype of a completely wireless laparoscope by making use of the latest in electronic and optic miniaturization. Design requirements were defined to mimic a standard 10 mm adult laparoscope. An 8 mm diameter (CMOS) camera was used, which delivered standard definition TV resolution at an image refresh rate of 30 Hz. A wide-angle lens was chosen, and a focusing mechanism was designed. Instead of a fiber-optic cable, illumination was achieved using four miniature LED lights. A 2.4 GHz wireless transmission with adequate range for use in an operating theater was chosen. A wireless receiver on a standard personal computer was used to drive a video monitor using off the shelf image processing software. A built-in rechargeable battery powered the wireless laparoscope. Flicker-free in vitro wireless video transmission was achieved. The laparoscope was made waterproof with a front cover lens and can be gas or chemically sterilized. The prototype laparoscope weights 78 g as compared with 900 g for a typical 10 mm laparoscope, camera, fiber-optic, and camera cables. Drawbacks of the prototype include reduced resolution of the video image as compared to high definition (HD) TV quality available on the most recent commercial camera systems. This experimental prototype has illustrated the feasibility of wireless endoscopy systems. The expected benefits include improved ergonomic maneuverability, reduced weight, and decreased electric power requirements.

This paper discusses the development, processing steps, and evaluation of a smart build-plate or baseplate tool for metal additive manufacturing technologies. This tool uses an embedded high-definition fiber optic sensing fiber to measure strain states from temperature and residual stress within the build-plate for monitoring purposes. Monitoring entails quality tracking for consistency along with identifying defect formation and growth, i.e., delamination or crack events near the build-plate surface. An aluminum alloy 6061 build-plate was manufactured using ultrasonic additive manufacturing due to the process’ low formation temperature and capability of embedding fiber optic sensing fiber without damage. Laser-powder bed fusion (L-PBF) was then used to print problematic geometries onto the build-plate using AlSi10Mg for evaluation purposes. The tool identified heat generation, delamination onset, and delamination growth of the printed L-PBF parts.

Large screen display system has good prospects for the formation of gaps that have been published. The introduction of this thesis programming before large-screen display system on the current development of software technology involved in a more comprehensive overview and discussion. In introducing the structure of the remote large screen systems design and related implementation techniques, the article discusses the big screen remote system software development, and details of video programming. Due to time and capacity constraints, only the planning and design to complete a thesis as part of the program inside the actual function, but also be further improved.
