  • Publication number: 20150223027
    Abstract: According to one embodiment of the present invention, a method for calculating the location of a terminal in a wireless communication system, which is to be performed by the terminal, comprises the steps of: transmitting, to a location server, a request for location estimation assist data for calculating the location of the terminal; receiving the location estimation assist data from the location server; and calculating the location of the terminal using the location estimation assist data. The location estimation assist data includes radio map information including a received signal strength (RSS) value from each access point collected at a plurality of location estimation reference points in a region having a predetermined range. The radio map includes information regarding the location estimation reference points (hereinafter, referred to as “update points”) which require an update of the radio map.

  • Publication number: 20140343838
    Abstract: The present invention relates to a method for calculating trip paths determined by a departure point and a target point by using traffic information in a terminal. The method includes the steps of: requesting traffic information related to a trip from a server; receiving the traffic information related to the trip from the server; and calculating the paths by using the received traffic information, wherein the received traffic information includes traffic events corresponding to information on disturbances in the traffic flow in an area or the path related to the trip, and performance parameters corresponding to information on traffic flow in a road segment within a constant radius from the departure point, and wherein the performance parameters can be received from the server in the case where there is congestion heavier than a predetermined level within a constant radius from the departure point.

  • Publication number: 20140118592
    Abstract: A CMOS imaging sensor with ernbedded feature extraction capability operatable in different modes by a method that includes the steps of: (a) operating the CMOS imaging sensor in a motion-detecting mode at a first power level using circuitry on the imaging sensor that generates motion data based on received images detected by pixels in the pixel array; (b) switching the imaging sensor from the motion-detecting mode to a feature extraction mode in response to detecting motion; and (c) operating the imaging sensor in the feature extraction mode at a second power level that is higher than the first power level.
