Abstract:
A monitoring device according to an embodiment of the present invention includes a master device which generates first sensing data by detecting an output voltage or an output current of a first photovoltaic array; and at least one slave device which is connected to the master device by a serial expansion port, generates second sensing data by detecting an output current of a second photovoltaic array, and transmits the second sensing data to the master device. The master device transmits the first sensing data and the second sensing data to a wireless network.
Abstract:
Disclosed are an apparatus and a method for recognizing a human in an image, which find a robust human feature and recognize human based on the found feature. The apparatus according to the present invention includes a learning unit and a human recognition unit. The learning unit calculates a boundary value between human and non-human based on feature candidates extracted from a learning image, detects a feature candidate for which an error is minimized as the learning image is divided into the human and the non-human using the calculated boundary value, and determines the detected feature candidate to be a feature. The human recognition unit extracts a candidate image where human may be present from an acquired image, and determines whether the candidate image corresponds to human based on the feature that is determined by the learning unit.
Abstract:
Provided are an apparatus and a method for checking a store visit in real time and providing a reward according to the store visit without using a chargeable communication channel which is included in a mobile communication device carried by a customer. The provided apparatus includes a sound signal receiving unit which receives a sound signal transmitted from a mobile communication device of a customer and restores an identifier from the received sound signal; and an information processing unit which generates check-in information by extracting customer information, a check-in date, and time information from the identifier restored in the sound signal receiving unit and combining the extracted information with store information and device information stored in the corresponding check-in apparatus, and then transmits the generated check-in information to a check-in server.

본 발명은 HR-WPAN을 지원하는 무선 디바이스에서의 서비스 품질보장 및 경로 다이버시티를 제공하기 위한 무선 메쉬 네트워크에서 프레임 에러율(FER:Frame Error Rate) 기반의 서빙 PNC(Piconet coordinator) 선택 방법 및 이를 이용한 무선 디바이스 장치에 관한 것으로서, 상기 무선 디바이스가 서빙 PNC를 결정하여 데이터 통신을 수행하는 도중에 주기적으로 주변의 PNC들의 FER을 확인하여 최적의 채널 상태를 갖는 PNC를 재 선택하여 통신하도록 함으로써, 효율적인 통신 시스템을 실현한다. 피코넷 코디네이터(PNC), 프레임 에러율(FER), 무선 메쉬 네트워크(WMN), pPNC, cPNC
Abstract:
A home appliance controlling device, a home appliance controlling system, and a method thereof are provided to determine whether to control home appliances by using a lot of sensing information, and to notify a user of the results or to automatically control the corresponding home appliances. A wireless sensor node unit(100) senses living spaces and states around the living spaces, and transmits sensing information to a home appliance controller(200). The home appliance controller(200) collects the sensing information delivered from the node unit(100), and determines a home appliance to be controlled and a controlled operation of the home appliance on the basis of the sensing information and pre-stored control information, then provides the results to a user or delivers a control signal to the corresponding home appliance.
