Abstract: A plasma-activated gas disinfection device includes a plasma generating unit, a disinfection chamber, an air pump and a fluid control module, where the plasma generating unit works in a first working mode during a first time period, and generates a first plasma active gas in the first working mode; the plasma generating unit works in a second working mode during a second time period, and generates a second plasma active gas in the second working mode; and the first time period is before the second time period, and alternatively, the first time period is after the second time period, such that a disinfection object in the disinfection chamber is disinfected. The plasma generating unit in the present disclosure is a simple device, and only one discharge module is used for generating different plasma active gases.

Abstract: A multi-monitor computer system includes a plurality of display devices communicating with at least one computing device executing an application management procedure. The application management procedure enables an application window available on one display device to be moved entirely to another display device by selecting the other display device from a dialog box displayed in response to a pointer-dragging input gesture on the application window.
