Abstract: An encoding/decoding apparatus and method for controlling a channel signal is disclosed, wherein the encoding apparatus may include an encoder to encode an object signal, a channel signal, and rendering information for the channel signal, and a bit stream generator to generate, as a bit stream, the encoded object signal, the encoded channel signal, and the encoded rendering information for the channel signal.

Abstract: A motion pillow includes an air bag connected to an air pump through an air hose, an inner cover to wrap the air bag, an outer cover to wrap the inner cover at the outside of the inner cover, and a noise reduction device between the air pump and the air bag. The noise reduction device includes a housing, a first connector to protrude from one end of the housing, connected to the air pump, and having an inner diameter smaller than that of the housing, a second connector to protrude from the other end of the housing, connected to the air bag, and having an inner diameter smaller than that of the housing, a sound absorbing material filled in a partial space inside the housing, and a vibration-proof material filled in the remaining space inside the housing where the sound absorbing material is not filled.

Abstract: A motion pillow according to an embodiment of the present disclosure includes a body, a motion system, a connector, and a valve. The body includes a plurality of airbags provided therein. The motion system includes a pump allowing air to enter and exit the airbags, a sensor measuring air pressures of the airbags, a sound receiver receiving sound from around the body, and a controller controlling operating mode in accordance with measurements of the sensor. The connector connects the airbags and the motion system. The valve opens and closes the connector. When at least one airbag among the plurality of airbags is pressed and air is introduced to the sensor through the connector, the controller is configured to switch the operating mode from standby mode to active mode. Significantly improved convenience and satisfaction of sleep are provided to users.

Abstract: The present invention provides an external force detecting system and a method for driving an external force detecting system. The external force detecting system according to one embodiment of the present invention comprises: a body unit including a plurality of identical air bags therein; a driving unit including an electric pump for inflating the air bags by injecting air thereinto or deflating the air bags by discharging air therefrom, and a processor for controlling an operation of the electric pump and detecting an air bag that is pressurized by an external force applied to the body unit; a plurality of ventilation paths provided in the same number as the air bags and having one end portion thereof individually connected to each air bag of the body unit and the other end portion thereof connected to the driving unit; and an air pressure sensing unit, disposed between the one end portion and the electric pump, for measuring air pressure for each air bag in which the same amount of air is injected.
