Abstract: Provided is a Raman scattering measurement apparatus including a light source which emits light to smoke particles, a filter configured to block light which is incident to the smoke particles and passes through the particle and to allow Raman scattered light to pass therethrough, and a photodetector which detects the Raman scattered light passing through the filter in order to distinguish fire smoke generated due to a true fire from non-fire smoke generated due to daily life or industrial activity. The present invention also provides a fire determination apparatus including a unit which reads a Raman shift from Raman scattered light detected by the photodetector of the Raman scattering measurement apparatus, estimates a smoke component from the read Raman shift, and determines fire/non-fire from the estimated smoke component and a method thereof.

Abstract: An apparatus and a method for filtering a broadcast message in a wireless network access equipment is discussed. The method includes searching for a registered communication terminal that should respond to a received broadcast message; checking whether the received broadcast message forwarding to the searched communication terminal requires a response; and transmitting a response instead to the communication terminal when the received broadcast message requires a response.

Abstract: Provided are a photographing method and apparatus using face pose estimation. The photographing method includes: detecting a face area from an input image; estimating pose information in the detected face area; and determining a face direction based on the estimated pose information and recording the input image according to the face direction. Accordingly, when a face of a subject looks at something other than a camera, a picture is not taken, and thus a failed photograph is prevented.

Abstract: A wireless network for sharing flexible data between one master and at least two slaves in real time.

Abstract: A method and apparatus for image processing includes detecting a face area in an input image, detecting an eye in the detected face area, determining a center point based on the detected eye, and performing warp processing on the input image based on the center point. Accordingly, it is not necessary to manually set areas for the warp processing.

Abstract: Disclosed is a digital signal processing apparatus of a communication terminal for adaptably transmitting voice data to allotted uplink channels and a voice data transmission method thereof. The digital signal processing apparatus comprises a plurality of speech coders for compressing the sampled voice data with each compression rate predetermined according to the number of packet channels capable of being allotted, a plurality of channel coders for channel-coding each set of voice data, compressed by each speech coder, according to respective predetermined codes, and a switching section, for outputting voice data which are compressed and channel-coded corresponding to the number of the allotted packet channels when packet channels are allotted.

Abstract: A method of providing a group call service in a radio network is provided. A BS, which does not cover a GCA but is located in a radio network near to the GCA, generates extended group call service information including information about BSs that cover an NGCA and broadcasts the extended group call service information. Upon receipt of the extended group call service information, an MS selects a BS in the best service condition among BSs set in the extended group call service information as a BS from which to receive an extended group call service and receives group call paging information from the BS. The MS analyzes the group call paging information and decides whether the group call service is available from the BS. If the group call service is available, the MS registers and connects to the selected BS and receives the group call from the BS.

Abstract: Disclosed is an encryption code for encrypting data to be transmitted or received during short-distance communication, namely, an encryption key generator for generating an encryption key, in order to transmit the encryption key to an integrated mobile communication terminal and a service terminal during short-distance secure communication. The two terminals encrypt data using the encryption key and receive or transmit the data, thereby implementing authentication and secure communication.

After detecting the manual instruction, a registration is made with a second communication network when the mobile terminal moves into a coverage area of the second communication network. A detection is made, after the registration, as to whether the handover of the mobile terminal is possible, and a handover process is started.
