Embodiments relate to systems and methods for instantiating and operating a virtual appliance monitor in a cloud. An alternating current of a frequency, which is lower than stationary frequency, is inserted periodically into the alternating current of stationary frequency. The lens module and the charge-coupled device module are arranged on the two planes of the supporting device, respectively. The invention, used with or without the present subcombination apparatuses, enables stable and precise positioning of personal electronic devices in almost any situation where rapid, impromptu, or reversible deployment is desired.
