Abstract: An electronic apparatus includes a first communicator, a second communicator and a controller. The first communicator has one of a first operation mode for a first communication with an external apparatus, and a first idle mode for pausing the first communication. The second communicator has one of a second operation mode for a second communication different in standard from the first communication with an external apparatus, and a second idle mode for pausing the second communication. The controller controls the first communicator and the second communicator to adjust a length of a simultaneous operation section where the first operation mode and the second operation mode are simultaneously implemented, in accordance with a degree of interference between the first communication and the second communication. With this, performance of wireless communication is more efficiently improved.

Abstract: An apparatus for providing feedback on a user input and a method of providing the same are provided. The apparatus includes: a user input receiver which receives a user input; a signal generator which generates a composite signal including at least one of a sound signal and a vibration signal; a thin film speaker which is attached under the user input receiver and generates a feedback signal on the user input according to the composite signal generated by the signal generator; and a controller which controls the signal generator to compose the sound signal and the vibration signal.

Abstract: A stone bed includes: a stone mat having a wood frame which a sheet is covered around, the wood frame wherein a copper plate, a protective insulating material, a plane carbon heating element, a first protection film, a second protection film, an electromagnetic wave shielding, a third protection film, a far infrared ray nonwoven fabric, and a natural stone are sequentially laid from a bottom, the wood frame having controllers and anion emitters on its both top ends, the controller comprising a power display unit, a selection switch, a temperature control switch, and a temperature display lamp, and a power input cord which is shielding processed; and a bed body having a top surface which the stone mat is mounted on.
