Abstract: PURPOSE: A method and an apparatus for sensing meal activity are provided, which can sense accurately a meal behavior by using date sensed by plural pressure sensors. CONSTITUTION: A sensor data collecting part(110) collects data detected by a plurality of pressure sensors installed at a smart dining table mat. A filter(120) filters collected data. A controller(130) analyzes filtered data, measures pressure variation amount through analyzed data, and judges meal behavior through the measured pressure change amount. A data transceiver(140) transmits the meal behavior information according to the meal behavior to the information processing device.

Abstract: A visual enhancement device for a visually-handicapped person is provided to detect accurately information about the current location and distance of an obstacle by using an ultrasonic beam forming method. A visual enhancement device for a visually-handicapped person includes a recognition unit(10) and a stimulation unit(20). The recognition unit detects the current location of an obstacle and a distance from the obstacle through an ultrasonic beam forming method. The stimulation unit receives obstacle information from the recognition unit and stimulates the skin of a user according to intensity and intervals corresponding to the obstacle information. The recognition unit includes a spectacle frame(11) having a wireless communication part(11a) for transmitting the obstacle information of the stimulation unit and a lens part(12) having an ultrasonic sensor array(12a) for converting received ultrasonic waves to the obstacle information through an ultrasonic beam forming algorithm.

Abstract: An apparatus and a method for detecting fall-down, and a system and a method for emergency aid using the same are provided to allow elderly persons to enjoy their safe life irrespective of a place and a time by using a portable terminal. An apparatus for detecting fall-down includes a storing unit, an angular velocity measuring unit, an acceleration measuring unit, an acceleration extracting unit(15), and a fall-down determining unit(16). The storing unit stores fall-down data vectors. The angular velocity measuring unit measures an angular velocity value. The acceleration measuring unit measures an acceleration value. The acceleration extracting unit extracts a kinetic acceleration value and a gravitational acceleration value by filtering the acceleration value measured by the acceleration measuring unit. The fall-down determining unit converts the angular velocity value which is measured by the angular velocity measuring unit, and the kinetic acceleration value and the gravitational acceleration value which are extracted by the acceleration extracting unit, into a fall-down data vector, and determines a user's fall-down by comparing the converted fall-down data vector with the fall-down data vector stored in the storing unit.
