Abstract:
A sound wave based wireless network wake-up control method and a wireless sensor network using the same are provided. An embodiment of the present invention relates to a wireless device composing a wireless sensor network capable of receiving data with an external device or capable of transmitting the data by operating the external device with sound wave transmission. The sound wave based wireless network wake-up control method controls the wake-up with the sound wave using the small microphone and the speaker in order to minimize power in the wireless sensor node by minimizing the waiting time of a transceiver.

Abstract:
Provided is a wireless power transmission system for operating an energy zone. The wireless power transmission system comprises one or more wireless power transmission devices and one or more wireless power receiving modules. The wireless power transmission devices wirelessly transmit power to the inside of the energy zone capable of charging one or more mobile devices. The wireless power receiving modules are installed in the mobile devices, respectively. The wireless power receiving modules charge the mobile devices by using the power which is wirelessly received from the wireless power transmission devices. The present invention is provided to wirelessly charge the mobile devices in the energy zone, thereby enabling users to conveniently charge the mobile devices at the outside.

Abstract:
PURPOSE: An image based wireless sensor network system and a method thereof are provided to efficiently use the wireless resource and power. CONSTITUTION: An event is detected(S610). Data related to the detected event is transmitted to a control center(S620). An image is created by photographing surroundings(S630). The created image is stored(S640). The property of the image is extracted(S650). The property of the extracted image is transmitted to the control center(S660).
Abstract:
PURPOSE: A low power smart key system using a low power wireless sensor network is provided to perform power transmission in different power by the kinds of the data. CONSTITUTION: A wireless network module(160) communicates with a control box(200) by the mode of a wireless network communication. A control unit(150) controls the wireless network module. A first signal is transmitted to a first power under the control of the control unit. A second signal is transmitted to a second power under the control of the control unit.
Abstract:
PURPOSE: A method for controlling an embedded store is provided to enable s user to check and control of product state information through the web server about a product purchased through a web server. CONSTITUTION: A flowerpot which has an embedded system is registered and sold on a web server(S110). The web server manages each flowerpot by inputting identity information per every flowerpot(S111). A user purchases the flowerpot through the web server(S120). The user purchased an item interlinked to the flowerpot through the web server. The user controls the flowerpot by checking product state information of the flowerpot and delivering information of the flowerpot through the item. If the delivery of the flowerpot is completed, the flowerpot is arranged to a predetermined space(S121). Based on a personal information of a user, the web server checks whether the purchased flowerpot and the flowerpot which the user wants to identify coincides(S130).
Abstract:
PURPOSE: A sensor node and a portability processing method thereof are provided to reset a routing route by letting a sensor node to determine portability. CONSTITUTION: Beacon signals are received from a router node(S11). The average of the received signal strength of the beacon signals is calculated(S18). Whether or not a portability trend exists is determined, and Whether or not the routing path is reset is determined(S19). If difference between the receiving signal strength of a parent router node and the receiving signal strength of other router nodes is higher than a predetermined threshold value, the connection to the other router nodes is requested to the corresponding router node(S21).
