Abstract:
Provided is a method for load balancing using statistical information in a base station in a wireless communication system. The method comprises the following steps of: measuring a load of at least one cell managed by the base station; exchanging the measured cell load information with one or more neighboring base stations; determining one or more MLB application candidate cells necessary to change CIO using the load information; determining one or more MLB application targeted cells among the MLB application candidate cells; performing a CIO change procedure with the MLB application targeted cells; selecting one or more terminals to be noticed of the CIO change; and notifying the selected terminals of the CIO change.

Abstract:
The present invention relates to a method and a system for preventing loss using the state of a hearing aid and, more specifically, to a method and a system for preventing loss of a hearing aid, capable of determining the separation of the hearing aid from a user by using sensing information of a sensor changing according to the movement of the hearing aid. A change value due to changes in movement of the hearing aid is measured from at least one sensor among an acceleration sensor, a temperature sensor, and a light sensor of the hearing aid, and the separation state of the hearing aid from the user is determined by using the measured change value.

Abstract:
An ultrasonic probe and a manufacturing method thereof are provided. The ultrasonic probe improves performance by separating first tiles, which transmits ultrasonic beams, and second tiles, which receive the ultrasonic beams, from each other. The ultrasonic probe comprises: the n number of the first tiles which transmit ultrasonic beams to an object; and the m number of the second tiles which receive the ultrasonic beams fed back from the object.
Abstract:
PURPOSE: A transmission and reception apparatus in an FM-UWB communication system to reduce power consumption controls modulator and the demodulator to operate when a pulse signal is inputted, and thereby power consumption can be reduced. CONSTITUTION: An edge detector (31) produces a predetermined pulse signal at each generation time of edges of digital signal indicating transmission data. FSK (frequency shift keying) modulator (32) outputs a modulated signal wherein the digital signal is modulated with different frequencies according to the digital signal's value. A FM frequency modulator (33) outputs a modulated signal wherein the modulated signal is modulated with different waveforms according to a modulated signal's frequency outputted from the FSK modulator in sections where the produced pulse signal is present. In the rest sections of the sections where the pulse signal is present, power supply to the FM modulator is blocked. [Reference numerals] (31) Edge detector; (32) FSK modulator; (33) FM modulator; (34) Amplifier; (AA) Digital signal; (BB) Ultra-wideband signal
Abstract:
PURPOSE: A lighting device is provided to obtain 360 degree beam-raider angle by a simple structure. CONSTITUTION: A light emitting unit(130) comprises a printed circuit board(132) in which many light emitting devices(134) are installed. Heat radiating units(140) are arranged along the circumference of an outer side of the light emitting unit and spaced from each other to emit beams to different directions. The heat radiating unit(140) emits heat to outside. The heat radiating unit(140) emits heat from the light emitting unit to outside. The light emitting units(130) are arranged in the heat radiating unit to be overlapped with each other.
