Abstract: An apparatus for providing information about an available service using a proxy server and a method thereof. The apparatus includes an available service checker, a database, an available service searcher, and an available service broadcaster. The apparatus may provide information through the proxy server regarding available services of a device that is not currently connected to a basic service set (BSS), thereby preventing generation of excessive amount of traffic.

Abstract: Disclosed is a message communication method of transmitting and receiving a certain message, independently of any network, without privacy invasion issues. The method includes generating vendor specific data on the basis of input information, adding the generated vendor specific data to a P2P information element of a probe request frame, and transmitting the probe request frame to another message communication apparatus. Thus, an apparatus conforming to a Wi-Fi Direct standard may transmit/receive a certain message to/from another terminal independently of a use region, a use environment, and a network of a large telecommunication vendor, without privacy invasion issues.

Abstract: A cost-cognitive base station apparatus, a cost-cognitive user terminal, and a cost-cognitive network method, in which by recognizing costs based on network congestion, a user may select and receive appropriate network services, thereby reducing telecommunication expenses and inducing the user to a less congested network, which leads to improved network management efficiency.

Abstract: The present invention relates to smart glasses, and the smart glasses include: a frame mounted with lens; a pair of temples extended in one direction from both side ends of the frame so as to face each other; a rear camera mounted at an end of the temple and configured to photograph a rear image of a wearer; a display unit installed at one side of the lens and configured to display the rear image photographed by the rear camera; and a control device configured to control an operation of each of the constituent elements, thereby enabling a user to check a situation in the rear view without turning his/her head.

Abstract: An apparatus and a method for managing instant connection based on a wireless local area network are provided. The method includes: creating, by an accessed terminal, connection information required for setting connection therewith; creating, by the accessed terminal, a management frame by using the connection information; transmitting, by the accessed terminal, the created management frame to a peripheral terminal; receiving, by the peripheral terminal, the management frame and extracting connection information from the received management frame; and setting, by the peripheral terminal, connection with the accessed terminal by accessing the accessed terminal by using the extracted connection information to rapidly access a desired terminal without performing a device discovery process.

Abstract: Disclosed herein are an apparatus and method for informing a bus driver of a user's intention to get on or off a bus. The apparatus for informing a bus driver of a user's intention to get on or off a bus includes a getting-on information collection device. The getting-on information collection device includes a getting-on information reception unit, an arrival-expected bus identification unit, and a transmission information transmission unit. The getting-on information reception unit receives getting-on information entered by a passenger who desires to get on a bus at a bus stop via a getting-on information transfer device of the bus stop. The arrival-expected bus identification unit identifies a bus expected to arrive having the earliest expected arrival time at the bus stop based on a bus number. The transmission information transmission unit transmits the transmission information to the getting-on information notification device of the bus expected to arrive.

Abstract: There is provided a communication middleware apparatus for a host device, including: a profile manager configured to receive specification information of a guest device through a Low-rate Wireless Personal Area Network (LR-WPAN) module; an application program manager configured to search for an application program for a host device that has to be newly installed or updated, based on the specification information of the guest device, and to install or update the found application program for the host device in the host device; and a firmware manager configured to search for firmware for the guest device that has to be updated based on the specification information of the guest device, and to transmit the found firmware for the guest device to the guest device through the LR-WPAN module.

Abstract: A second harmonic laser beam is generated by passing a fundamental frequency laser beam through a single second harmonic generator (SHG) crystal more than two and preferably four times, to increase the amount of power converted from the fundamental beam into the second harmonic beam and to increase the overall efficiency of the conversion.
