| 20080234922 | Traffic-jam state calculation systems, methods, and programs - Systems, methods, and programs obtain probe information, the probe information comprising an average speed of probe cars traveling on each of a plurality of links in a predetermined area. The systems, methods, and programs detect, for each of the plurality of links, a first degree of a traffic jam corresponding to the link for each of a plurality of different thresholds by comparing the average speed with each of the thresholds. The systems, methods, and programs obtain traffic-jam information concerning the plurality of links, the obtained traffic information comprising a second degree of the traffic jam corresponding to each of the plurality of links. The systems, methods, and programs compare, for each of the plurality of links, the second degree of the traffic jam with the first degree of the traffic jam for each of the thresholds. The systems, methods, and programs select, for the predetermined area, a threshold from the plurality of thresholds for which the first degree of the traffic jam most matches the second degree of the traffic jam and utilize the selected threshold to determine a severity of the traffic jam for each of the plurality of links. | 09-25-2008 |
| 20080270013 | Vehicle position information providing devices, methods, and programs - Vehicle position information providing devices, methods, and programs acquire a first current position of a vehicle based on a radio signal received from a GPS satellite and acquire a second current position of the vehicle based on a signal received by a communication device that communicates over a mobile phone network. The devices, methods, and programs determine whether the first current position and the second current position coincide. If the first current position and the second current position do not coincide, the devices, methods, and programs cause the communication device to transmit information relating to the first current position to an information center. | 10-30-2008 |
| 20080270015 | Traffic situation determination systems, methods, and programs - Traffic situation determination systems, methods, and programs acquire a current position of the vehicle based on a radio signal received from a GPS satellite and determine a first travel path of the vehicle based on the acquired position of the vehicle. The systems, methods, and programs determine whether a road on which the vehicle is traveling has a traffic jam. If the road on which the vehicle is traveling has a traffic jam, the systems, methods and programs transmit first information relating to the first travel path from the vehicle to an information center. The systems, methods, and programs receive second information relating to a second travel path of the vehicle, the second information being received from a mobile phone communication center and being based on a mobile phone signal received by the mobile phone communication center. The systems, methods, and programs determine a road corresponding to the first travel path as having a traffic jam and determine a road corresponding to the second travel path, and not corresponding to the first travel path, as having no traffic jam. | 10-30-2008 |
| 20100309022 | DRIVING SUPPORT DEVICE, DRIVING SUPPORT METHOD, AND DRIVING SUPPORT PROGRAM - Information specifying an initial motion of a vehicle when travel is started on a road in a predetermined section is obtained, and information specifying an estimated motion, which is associated in advance with the initial motion, of the vehicle on the road in the predetermined section subsequent to the initial motion is also obtained. Based on the estimated motion, a guidance unit mounted in the vehicle provides guidance for supporting driving when traveling on the road in the predetermined section. | 12-09-2010 |
| 20100324806 | TRAVEL PATTERN INFORMATION OBTAINING DEVICE, TRAVEL PATTERN INFORMATION OBTAINING METHOD, AND TRAVEL PATTERN INFORMATION OBTAINING PROGRAM - Vehicle speed identification information for identifying vehicle speed of a vehicle on a road is obtained for a plurality of vehicles. Based on a distribution of the vehicle speed identification information, the vehicle speed identification information is classified into groups corresponding to motions of the vehicle. An occurrence probability of a motion of the vehicle is obtained based on the classification. | 12-23-2010 |
| 20110004370 | STOP HISTORY DATA ACCUMULATION SYSTEM, ACCUMULATION METHOD, AND ACCUMULATION PROGRAM - State information indicating an state of a vehicle is obtained. Based on the state information, group information is obtained that is formed from first stop information including a first stop position at which the vehicle stopped and formed from second stop information including a second stop position at which the vehicle stopped subsequent to the first stop position. Based on the group information, identification information for identifying a road zone including the second stop position is associated with the first stop position and accumulated. | 01-06-2011 |

| 20090068403 | POLYIMIDE FILM AND COPPER-CLAD LAMINATE USING IT AS BASE MATERIAL - To provide a polyimide film, which has excellent size stability and is suitable for a substrate for fine pitch circuits, especially COF (Chip on Film) being wired at a narrow pitch in the width direction of the film, and a copper-clad laminate using the film as a base material. | 03-12-2009 |
| 20090088551 | POLYIMIDE FILM - The objective of the present invention is to provide a polyimide film with decreased water absorption. A polyimide film, which is made of diamine and tetracarboxylic dianhydride, characterized in that tetracarboxylic dianhydride, which constitutes polyimide, contains tetracarboxylic dianhydride. | 04-02-2009 |
| 20100129605 | POLYIMIDE FILM AND METHOD OF MANUFACTURE THEREOF - The purpose of the present invention is to provide a polyimide film with excellent passage characteristic, especially in an automatic optical inspection system (AOI), not to mention running characteristic (easy slip characteristic) and adhesion. | 05-27-2010 |
| 20100241344 | TRAFFIC INFORMATION DISTRIBUTING APPARATUS - In a case where a CPU provided in an information distribution center has received, from a navigation apparatus, vehicle information together with a request command for requesting traffic information such as current traffic information, the CPU sets a road category that serves as a distribution target of the traffic information, based on one of a distance and a required travel time from a vehicle position to a destination. The CPU then extracts the traffic information that corresponds to the set road category and distributes it to the navigation apparatus. | 09-23-2010 |
