20100310206 | OPTICAL MODULATOR - A technical problem related to a traveling wave electrode type of optical modulator comprising a substrate having the electro-optical effect, optical waveguides formed in the substrate, and a traveling wave electrode formed above the substrate includes improvement of the characteristics such as optical modulation bandwidth, driving voltage, and characteristic impedance of the traveling wave electrode type of optical modulator. To solve the problem, the structure of ridge portions is optimized which is formed in such a manner that a part of the substrate at regions where electric field generated by a high frequency electric signal traveling through the traveling wave electrode is strong is reduced in thickness by digging. Further, a buffer layer is formed over the substrate where the ridge portions are formed and a conducting layer is formed over the buffer layer. The thickness of at least one part of the buffer layer along the normal line of a side surface of the ridge portions is less than the thickness of the buffer layer on a bottom surface between the ridge portions formed by digging and/or the thickness of the buffer layer on a top part of the ridge portions. | 12-09-2010 |

20090240398 | APPARATUS FOR CHANGING A VEHICLE SPEED SETTING OF CRUISE CONTROL - A vehicle speed setting of cruise control is changed based on an operation by a driver. At this time, it is determined whether the vehicle is traveling in a passing lane or a traveling lane (S | 09-24-2009 |
20090251355 | AUTOMOTIVE DRIVE ASSIST SYSTEM WITH SENSOR FUSION OF RADAR AND CAMERA AND PROBABILITY ESTIMATION OF OBJECT EXISTENCE FOR VARYING A THRESHOLD IN THE RADAR - An ACC system ( | 10-08-2009 |
20110050482 | OBJECT DETECTING DEVICE - The present invention is directed to provide an object detecting device which can reduce the influence of an error caused by temporal displacement between a detection result by a radar and a detection result by image processing and thus, the precision of object detection can be improved. An object detecting unit of an object detecting device comprises an image portion search means which searches image data captured by an image capture unit, referring to detection point data detected by a radar detecting unit, and detects an image portion corresponding to a target object to be detected; a detection point extracting means which extracts, from the detection point data detected by the radar detecting unit, detection point data corresponding to the target object to be detected, and an image portion correcting means which corrects, in accordance with the detection point data extracted by the detection point extracting means, the position of the image portion detected by the image portion search means. | 03-03-2011 |
20120176267 | OBJECT DETECTING APPARATUS - The judgment accuracy is enhanced to judge whether or not an object is actually exists. An object detecting apparatus includes an acquiring unit which acquires information of the object by means of a radar, an angle detecting unit which detects an angle of the object with respect to a subject vehicle, an extrapolating unit which extrapolates the information of the object, and a judging unit which judges whether or not the object actually exists on the basis of the information of the object acquired by the acquiring unit and the information of the object extrapolated by the extrapolating unit, wherein the judging unit relaxes a condition to judge that the object actually exists when the information, which is extrapolated if an amount of change of the angle is not less than a predetermined amount, is included in the information of the object to be used to judge whether or not the object actually exists, as compared with when the information, which is extrapolated by the extrapolating unit, is not included. | 07-12-2012 |
20130173132 | BRAKING FORCE CONTROL APPARATUS FOR A VEHICLE - In a braking force control apparatus which controls a braking force applied to a vehicle based on a relation thereof with an obstacle ahead of the vehicle, irrespective of a braking operation of a driver, a lateral force is predicted which can be generated in cases where avoidance steering is carried out by the driver, in order to avoid an obstacle which has been detected, and an actual braking force actually applied to a longitudinal direction of the vehicle is limited in accordance with a braking force which can be applied in the longitudinal direction of the vehicle and which is calculated based on the lateral force thus predicted. According to this, in the braking force control apparatus which controls the braking force of the vehicle, the lateral force for avoiding a collision with the obstacle by means of steering is obtained. | 07-04-2013 |
20140336917 | VEHICLE CONTROLLER - A vehicle controller includes: a collision preventing unit that performs a collision avoiding operation of a vehicle with an object around the vehicle, an operation of the collision preventing unit being suppressed when turning behavior of the vehicle is detected; and a control unit that controls the operation of the collision preventing unit so as not to suppress the operation of the collision preventing unit when the vehicle is decelerated.

20110130881 | CENTRAL AIR-CONDITIONING SYSTEM - Regarding rooms other than a room being targeted, a controller controls the rooms in energy-saving conditioning mode when a person is not detected in the rooms, even when the rooms are scheduled to be controlled in ordinary conditioning mode in a temperature control schedule. At this time, when the controller judges that the person has exited the room, the controller controls the targeted room in energy-saving conditioning mode, in rapid conditioning mode. As a result, the room is rapidly conditioned such that the temperature changes from an energy-saving temperature t to an ordinary set temperature by the time the person who has exited the room enters the room. As a result, unnecessary conditioning of the room set to be conditioning in ordinary conditioning mode can be reduced, and energy consumption can be reduced. In addition, comfort of the person entering the room can be ensured by prediction of the movement of the person. | 06-02-2011 |
20110231019 | CENTRAL AIR-CONDITIONING SYSTEM - A central air-conditioning system conditions a house having a plurality of rooms. When a person is not present in any of the rooms, each room is conditioned in energy-saving conditioning mode having a low load. On the other hand, when the person is detected in any of the rooms, a controller switches an operating mode for conditioning the room, in which the person is detected, from the energy-saving conditioning to rapid conditioning. Air-conditioner ducts respectively connected to the remaining rooms are closed. Therefore, cold air or warm air from an air-conditioning unit is supplied to the room in which the person is detected, while the cold air or warm air is not supplied to the rooms in which the person is not present. As a result, the room that has been switched from energy-saving conditioning to rapid conditioning is conditioned in a concentrated manner. | 09-22-2011 |
