Filed: 2006-06-16
Abstract: <P>PROBLEM TO BE SOLVED: To provide a system and method of measuring the position of a terminal using a parameter of a wireless broadband signal, used for a hand-over.  <P>SOLUTION: Provided is a position measuring system and method using a Wireless Broadband (WiBro) signal. The position measuring system measures the position of a terminal using relative delay information that is a parameter of the WiBro signal, used for a hand-over. Since the position of a terminal is measured using a parameter for a hand-over of an existent Wibro system, additional data measurement is not required for the position measurement. Furthermore, efficiency in the use of a parameter of the WiBro system can be improved by using the parameter used only in the hand-over for position measurement.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Filed: 2006-06-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide a position-detecting system having a simple constitution, as well as, accurately synchronizable base stations.  <P>SOLUTION: The position-detecting system comprises a reference station 101, the base stations 102-104, a position calculator 105 and a communication terminal 106. The reference station 101 is disposed at equal distance from the base stations 102-104. The base stations 102-104 are triggered by a reference signal transmitted from the reference station 101 and receive a measurement signal transmitted from the communication terminal 106. The position of the communication terminal 106 is calculated, by aggregating the arrival time differences. Since the reference station 101 is disposed at an equal distance from the base stations 102-104, the time when the base stations 102-104 receive the reference signal 110 is the same among the base stations. Thus, the arrival times for the measuring signal are measured accurately at the base stations 102-104.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To effectively restrain a variation in engine speed immediately after an increase in electric load such as the transition of the electric load from an off-state to an on-state.  <P>SOLUTION: A cooling water temperature when an electric fan being the electric load is turned on, is estimated from a vehicle speed. Its estimated water temperature TWb is set as a value smaller by a predetermined quantity than the water temperature when the electric fan actually is turned on. When the actual cooling water temperature TWa reaches the estimated water temperature TWb, that is, before the electric fan actually is turned on, a rotational variation measure (for example, a quantity increase correction of the auction air volume and a fuel injection quantity) for restraining a rotational variation in an engine is performed (Step ST12 to ST15) to be prepared for an increase in a power generation quantity (torque) of an alternator when turning on the electric fan. By performing such a measure, the rotational variation at the transition of the electric fan from an off-state to an on-state can be effectively restrained.  <P>COPYRIGHT: (C)2008,JPO&INPIT
