Provided is an apparatus and method for analyzing a concentration level of a driver, the method including analyzing quantitative data associated with a time at which a line of sight (LOS) of a driver is dispersed and a time at which the LOS of the driver is focused, analyzing a reaction speed of a human machine interface (HMI) when a command based on device input information, voice information, and gesture information is input, and evaluating a degree of LOS dispersion of the driver based on the quantitative data of the driver and the reaction speed of a user interface (UI) of the HMI.

Method and apparatus for analyzing concentration level of driver

Provided are an EMF model synchronization method and system. The system calculates a weight based on a hierarchy for an object identifier in a changed model, when the change of the model occurs in an EMF model which has an XML element path as an attribute. The system accumulates the calculated weight to a sum of weights. When the sum of weights becomes greater than the threshold value, the system simultaneously updates all models which are changed until the sum of weights becomes greater than the threshold value, thereby synchronizing change contents. As a hierarchy of an identifier changed on an XML path becomes higher, the weight is determined to have a larger value.

EMF model synchronization method and system

An Ethernet-MOST gateway apparatus for exchanging data between a MOST network transferring multimedia data within a vehicle and a packet network for a computer and Internet communications. The Ethernet-MOS gateway apparatus including: an Ethernet frame interface unit connected with a packet network to transmit and receive an Ethernet frame, and converting the Ethernet frame into a MOST frame; a MOST frame interface unit connected with a MOST network to transmit and receive the MOST frame, and converting the MOST frame into the Ethernet frame; and a switch fabric connecting the Ethernet frame interface unit and the MOST frame interface unit.

Ethernet-MOST gateway apparatus

Provided is a distributed and asynchronous implicit token carrier sense multiple access/collision avoidance (CSMA/CA) protocol guaranteeing quality of service for both real time and non-real time traffic. The implicit token CSMA/CA protocol allocates a band in an entire bandwidth to voice traffic and allows the remaining bands to be used for data traffic. The implicit token CSMA/CA protocol includes applying a token passing protocol to transmit voice traffic in real time by having a band in an entire bandwidth allocated using a predetermined data frame and applying a CSMA/CA mechanism to transmit data traffic in non-real time by employing remaining bands not allocated to the voice traffic using another predetermined data frame.

Hybrid implicit token carrier sensing multiple access/collision avoidance protocol

Provided is a network global positioning system (GPS) terminal. The network GPS terminal includes: a GPS receiver receiving GPS data; a GPS processor processing the received GPS data to a predetermined form; a network communication part communicating with an external apparatus through a network in order to receive a request for the GPS data from the external apparatus, and transmit the processed GPS data to the external apparatus in response to the request; a security access controller authenticating the external apparatus; and a network management part managing connection information and security information of the external apparatus, the network communication part simultaneously communicating with at least one external apparatus using a TCP/IP protocol. A method of providing GPS data using a network is also provided.
