Abstract:
A display system adaptable to changes in video signals and a method thereof display a video signal, which has a first display aspect ratio, in a display system, which has a second display aspect ratio. The display system includes a receiving unit for receiving the video signal, a detecting unit for detecting the first display aspect ratio of the video signal and a comparing unit for comparing the first display aspect ratio with the second display aspect ratio according to the first display aspect ratio detected by the detecting unit, and determining whether at least one covering structure is enabled in the display system so as to show the video signal corresponding to the display system.
Abstract:
A hot water and steam generator includes a base, a first seal plate mounted on the base, a container mounted on a side of the first seal plate, a second seal plate mounted on the base, a mounting ring mounted between and sealed by the first seal plate and the second seal plate, and a rotation wheel rotatably mounted in the mounting ring. Thus, the hot water and steam generator increases the water temperature rapidly due to collision and friction of water molecules by rotation of the rotation wheel so as to produce hot water and steam easily, rapidly and conveniently.
Abstract:
An image capturing system may include a first image capturing apparatus, a second image capturing apparatus and a securing apparatus. When in use, the user can rotate the first image capturing apparatus and/or uses its APP interface to adjust the shooting angle. Meanwhile, the second image capturing apparatus is configured to control the securing apparatus to rotate based on the adjustment made on the first image capturing apparatus, until the desired image sent by the second image capturing apparatus is shown on the screen of the first image capturing apparatus. The user then presses the shutter in the APP of the first image capturing apparatus and the command is sent to the second image capturing apparatus to actually take the picture or video and pass it back to the first image capturing apparatus for the user to review.
Abstract:
An electromagnetic pen with an amplitude-controlled inking function is provided, including a DC voltage source with a high voltage output source and a low voltage output source, a pen tip switch and a programmable LC circuit. The electromagnetic pen outputs an electromagnetic signal. The pen tip switch requires only a small amount of pressure to switch to high voltage output source and trigger the output electromagnetic signal so that the user feel comfortable in writing. The writing and drawing of the electromagnetic pen is controlled by the amplitude of the output electromagnetic signal, which corresponds to the pen tip pressure.
Abstract:
A hot water and steam generator includes a base, a first seal plate mounted on the base, a protruding container mounted on a side of the first seal plate, a second seal plate mounted on the base, a mounting ring mounted between the first seal plate and the second seal plate, and a rotation wheel rotatably mounted in the mounting ring. Thus, the hot water and steam generator increases the water temperature rapidly due to collision and friction of water molecules by rotation of the rotation wheel so as to produce hot water and steam easily and rapidly.
