Latest Patents

One of his latest patents is a combustor applied in a thermophotovoltaic system. This invention comprises a combustion device and a reversed tube covering the combustion device. The combustion device includes a combustion body made of a transparent and temperature-resistant material, along with a burning unit disposed within it. By utilizing a burning-supported medium during combustion, the radiant intensity is increased. The reversed tube further redirects the hot product gas to reheat the outer wall of the combustion body, resulting in uniform illumination and enhanced radiant intensity. This innovation allows a photovoltaic cell plate connected to the combustor to effectively transform light into electricity, fully utilizing a micro system and miniature energy to provide advanced electricity.

Another significant patent is the Low-Cost Continuous-Wave Laser Digital Particle Image Velocimetry system. This invention proposes a system that employs basic low-cost equipment, including a continuous-wave laser in mixed mode, a CCD camera, a photo-multiplier tube, an image-processing card, and a personal computer. The system features an add-on alternating-color planar laser-sheet generating facility to achieve planar velocity measurements. The laser beam is transformed into a planar laser sheet with alternating colors at a designated frequency. The CCD camera captures alternating-color images of the flow field seeded with small particles, which are then analyzed on a personal computer to determine the magnitude and direction of the velocity distribution using the cross-correlation method.
