Abstract: An axial flow impeller includes a hub, at least three base blades, and a cover blade detachably mounted to each base blade. When the impeller is applied in a medium environment having a high density and viscosity, the impeller will meet the requirement only by virtue of the base blade with the cover blade being removed. When the impeller is applied in a medium environment having low density and viscosity, the cover blade can be mounted in the front and/or rear of the base blade in order to improve the efficiency of the impeller. In this case, the consumption of electrical power can be reduced significantly while producing an equivalent propulsive force, thereby being advantageous for energy conservation. Therefore, the impeller can be adaptable to different medium environments and efficiency requirements, and thus can have good adaptability, need minimal investment cost and can be convenient to use.

Abstract: Image scanning and encoding technologies can be utilized to authenticate devices to virtual desktops and to transfer virtual desktop sessions between devices. One device (e.g., PC or laptop) may encode certain information into an image that is displayed on a display screen, while another mobile device equipped with a digital camera (e.g., mobile phone or tablet) can be used to scan the image on the display screen. Once the image is scanned, it can be decoded by the mobile device to get the information encoded in the image (e.g., device ID, session ID, etc.). The information obtained from the image can be used to authenticate a device or to transfer a virtual desktop session between the devices.
