Abstract:
An unmanned aerial vehicle is disclosed. The unmanned aerial vehicle includes a memory, a sensor unit, a camera, a moving unit, and a processor. The sensor unit is configured to sense the unmanned aerial vehicle or a surrounding object. The camera configured to take an image. The moving unit configured to generate power to move the unmanned aerial vehicle. The processor is configured to determine whether a user makes contact with the unmanned aerial vehicle. The processor is also configured to control the moving unit to allow the unmanned aerial vehicle to hover at a second location when the unmanned aerial vehicle is moved from a first location to the second location by an external force of a predetermined magnitude or greater while the contact is maintained.
Abstract:
An integrated circuit configured to detect a variation in a supply voltage using a phase of an input clock signal dependent on the variation in the supply voltage may include a clock delay circuit configured to delay the input clock signal output from a clock generator using each of different delay cell chains and generate a first delay clock signal and a second delay clock signal; and a phase controller configured to control a first phase so that a difference between the first phase and a second phase is 180 degrees, the first phase being a phase of the first delay clock signal, the second phase being a phase of the second delay clock signal.

Abstract:
A clock signal generating method includes receiving a duty code that represents a duty of a clock signal, and a period code that represents a period of a clock signal, and normalizing the duty code to the period code to output a normalized duty code. The clock signal generating method further includes controlling a rising timing of a clock signal in response to the period code, and controlling a falling timing of the clock signal in response to the normalized duty code to generate a timing-controlled clock signal.
