    Abstract: Disclosed is a system and method for searching and registering a wearable Bluetooth device in a surrounding area. The searching Bluetooth device broadcasts a session description protocol (SDP) request message by executing the SDP. When the SDP request message broadcast by the searching Bluetooth device is received, a surrounding Bluetooth device executes the SDP, generates an SDP response message, and transmits the SDP response message to the searching Bluetooth device. When the SDP response message is received, the searching Bluetooth device requests that the server provide the detailed information file of the surrounding Bluetooth device, based on server access information included in the SDP response message. When the detailed information file of the surrounding Bluetooth device is received from the server, the searching Bluetooth device stores the detailed information file.

    Abstract: In one embodiment, an integrated light transmission/reception optical system module includes a light receiving lens, a light source, and a light transmitting mirror. The light receiving lens receives light, concentrates the received light on a light detector disposed at a rear position, and has an optical path groove formed to be directed from a circumference to a central portion and formed to expose a front side. The light source outputs a pulse laser along the optical path groove from the circumference of the light receiving lens toward the central portion of the light receiving lens. The light transmitting mirror is disposed within the optical path groove, is located on a path of the pulse laser, and reflects in a front direction the pulse laser outputted from the light source. Other embodiments are also possible.

    Abstract: A high-efficiency high-integrated receiver is provided. The radar receiver according to an embodiment of the present disclosure includes a receiver configured to receive a radar signal, a processor configured to attenuate a magnitude of a low frequency band of the received signal of the receiver, a filter configured to perform a low pass filtering on an output signal of the processor, and an ADC configured to A/D convert the output signal of the filter. Accordingly, it is possible to demodulate all the signals being reflected from targets in various distances when even using a low resolution ADC, thereby reducing the manufacturing cost and power consumption.

    Abstract: A hybrid type transceiver for broadband large area beamforming is provided. A communication device includes: antennas; first phase shifters (PSs) configured to adjust respective phases of reception signals received via the antennas; and a first time delay (TD) configured to adjust delays for the reception signals the phases of which are adjusted at the first PSs. Accordingly, in designing a broadband communication system using a large area array antenna, the structure of the system can be simplified, a size can be reduced, power consumption can be reduced, and a resolution of the system can be enhanced.
