A drone formation control apparatus for controlling a plurality of drones included in a drone formation includes: an input unit which receives a drone control command which is a command for controlling the plurality of drones together; a movement command generating unit which generates a drone movement command which is a command to move the plurality of drones to a specific destination, based on the drone control command; and a movement command transmitting unit which transmits the drone movement command to at least one drone of the plurality of drones.

Apparatus and method for controlling drone formation

An average current controller configured for connection to display-components through a power switch. The average current controller includes first, second, and third comparators, an integrator, and a reference current generator. The first comparator compares a peak current level of reference current with a load current level of load current and outputs a first comparison result. The load current denotes current flowing through the display-components. The second comparator compares the peak current level of reference current with an average current level of the load current and outputs a second comparison result. The integrator integrates the second comparison result. The third comparator compares the integral value of the integrator with a predetermined value and outputs a third comparison result. The reference current generator sets the peak current level based on the first comparison result and the third comparison result and generates the reference current with the set peak current level.

Average current controller

A mobile terminal is presented. The mobile terminal includes a main display unit comprising a first display unit, a transparent display unit comprising a second display unit, the transparent display unit being attached to the main display unit such that the transparent display unit may be viewed at an angle in comparison to the main display unit, and a controller controlling a three-dimensional (3D) and a two-dimensional (2D) image to be output by selectively displaying an image on at least the first display unit or the second display unit while the main display unit and the transparent display unit are positioned at an angle.

Mobile terminal and controlling method thereof

A driver circuit is configured to drive light-emitting elements. The driver circuit includes a light-emitting element, a power switching element, a control circuit, and a charge pump circuit. The power switching element includes a first terminal connected to the light-emitting element and turns on and off the light-emitting element. The control circuit is connected to a second terminal of the power switching element and controls a switching operation of the power switching element. The charge pump circuit is connected between the control circuit and a power source for the light-emitting element and supplies current to the control circuit for driving the control circuit.
