Abstract:
A combined projector structure having a diverse stable display effect of the scene includes a holding space, in which freely-moving living organisms can be kept, an image device mounted on the edge of the holding space and facing toward the holding space. The image device can include a mounting element installed on the edge of the holding space, a kaleidoscope connected to the mounting element and facing toward the holding space, a photographic unit connected to the other end of the kaleidoscope. The photographic unit can record the scenes that appears in the other end of the kaleidoscope, and a projection unit connected to the photographic unit. Through the kaleidoscope, the displacement of the moving living organisms located in the holding space can be displayed in a diverse visual effect.
Abstract:
The instant disclosure provides a Power Factor Correction (PFC) boost converter including a PFC converter unit and a control unit and a frequency switching modulation method thereof. The control unit outputs a pulse width modulation (PWM) signal to the PFC converter unit for adjusting an electronic power output to a voltage converter. As the output load of the PFC converter unit increases, the control unit increases the frequency of the PWM signal. Conversely, as the output load of the PFC converter unit decreases, the control unit reduces the frequency of the PWM signal. Consequently, the switching loss of the PFC converter unit is reduced.
Abstract:
The preset invention relates to a promoter to target a fluorescent protein to the muscles of fish, such as A. nigrofasciatus, for ornamental purposes, which is a Mlc3 (myosin, light polypeptide 3, skeletal muscle) promoter. The Mlc3 promoter has the nucleotides of tilapia (Oreochromis niloticus) myosin light chain 3 (Mlc3) promoter region, which is potential to be a tilapia Mlc3 promoter to enhance protein expression in muscle of fish, particularly for the generation of ornamental fish.
