Abstract: A dyeing method for functional contact lenses includes the following steps: providing a dry lens body, including hydrogel with 0-90% water content, silicone hydrogel with 0-90% water content, or a combination thereof; preparing an amphoteric polymethyl ether prepolymer, combining the amphoteric polymethyl ether prepolymer with a hydrophilic monomer to form a masking ring material, and attaching the masking ring material to an inner surface of the dry lens body to form a masking ring layer; dropping a colorant onto the inner surface, making the masking ring layer surround the colorant, irradiating the colorant with an ultraviolet light and then heating and fixing the colorant to form a dyed layer on the inner surface; and placing the dry lens body in water to hydrate and removing the masking ring layer to obtain a wet lens body.

Abstract: In view of existing mobile devices which have the limitation of relatively small area of the touch screen, the present invention describes a virtual touch sensing method based on computer vision technology. The method includes the steps of using more than one sensor to detect the coordinates of an indicator in a virtual touching area, and calculating the respective screen coordinates according to the coordinates of the indicator, where the area of the operation surface of the virtual touching area is independent to the area of the screen. The present invention also disclosed a corresponding virtual touch sensing system which provides a predictive control interface, where the area of the control interface is independent to the area of the actual screen.

Abstract: A flush apparatus includes a control module, a solar cell and a rechargeable battery. The control module is used for controlling the flush apparatus to flush or not. The solar cell and the rechargeable battery are electrically connected to a power output terminal in parallel. The power output terminal is electrically connected to the control module for providing power to the control module.

Abstract: A power managing system includes a battery, a solar cell, a detecting circuit and a control module. The solar cell transforms a received light into a voltage and the battery is charged by the solar cell. The detecting circuit detects the voltage and correspondingly generates a detecting signal. The control module controls a pathway between the battery and the solar cell according to the detecting signal.

Abstract: A controlling device and a controlling system. The controlling device transmits controlling signals to an electronic device and receives operation statuses thereof through a power line. The controlling device includes a Human-Machine Interface (HMI) device for displaying the operation statuses of the electronic device. The controlling device includes a controller, an HMI device connected to the controller, a power supply for providing an electric power to the controller and the HMI device, and a power line network signal transmit/receive module connected to the controller.
