Abstract: A double-sided display device includes a first panel, a second panel, a light guide plate and a light source. The second panel is arranged opposite to the first panel. The light guide plate is arranged between the first panel and the second panel, and includes a main body portion including a first surface and a second surface, a first pattern arranged on the first surface, and a second pattern arranged on the second surface. The light source is arranged adjacent to the light guide plate. The first pattern is different from the second pattern.

Abstract: A smart toilet and an ozone assembly thereof are provided. The ozone assembly is provided for being connected to a water pipe of a water spraying assembly. The ozone assembly includes an ozone electrolyzer for being assembled to the water pipe and an ozone circuit module that is electrically coupled to the ozone electrolyzer. The ozone electrolyzer is configured to generate an ozone gas to be mixed into the water transported toward the water spraying assembly so as to form ozone water. The ozone electrolyzer is configured to maintain an ozone concentration of the ozone water to be within a range from 0.05 ppm to 0.3 ppm. The ozone circuit module is configured to drive the ozone electrolyzer while the water spraying assembly performs a water drawing process.

Abstract: An adjustable Venturi tube is provided and includes a water outlet segment and a water inlet segment. The water outlet segment has a gas inlet space therein and includes a chamber, a water flow selector disposed on the chamber, and a gas inlet pipe. The chamber has a gas inlet opening and a plurality of liquid-gas exits, which are in spatial communication with the gas inlet space. The water flow selector has a plurality of selective channels respectively facing the liquid-gas exits. The water outlet segment has a space and a water channel that is in spatial communication with the space. The water inlet segment and the water flow selector are configured to be moved relative to each other so as to allow the space to selectively be in spatial communication with at least one of the selective channels through the water channel.

Abstract: A computer system rescue method uses the AMtek iTablet Recovery to diagnose, unfold, restore an operating system with a Windows Pre-install Environment (WinPE) component and back up or recover an operating system or data with a Windows APIs image component. Firstly, in the low-level disk formatting, a disk area is selectively partitioned into three primary sectors and n logical partitions, or is unconfigured for installation of Linux. After installing the Windows system and the operating system used by the user in one primary sector, the AMtek iTablet Recovery is particularly installed in another sector or a mass storage device such as a plug-and-play portable hard drive, and then all the old data of the user is moved to the Windows.
