20110035183 | DEVICE, METHOD, AND PROGRAM FOR DETECTING POSITION - Sonic wave speed at a part is calculated considering the environment surrounding the part, sonic wave speed around the part is measured, and the accuracy of the position detection is improved. An ultrasonic wave transmitting device is arranged at a robot hand tip, hexahedrons which can contain the tip are set, and the ultrasonic wave transmitting-receiving devices are arranged at the top points thereof. Upon detecting the tip position, a top point that is close to the tip is selected as a specific point, and sonic wave speeds from other top points to this specific point are calculated. Based on these sonic wave speeds, sonic wave speed along a route from the tip to the specific point is calculated. Based on this sonic wave speed value and spread time of ultrasonic waves between the tip and the specific point, distance from the specific point to the tip is calculated. | 02-10-2011 |

20100321704 | THREE-DIMENSIONAL SHAPE MEASURING SYSTEM AND THREE-DIMENSIONAL SHAPE MEASURING METHOD - Chirped light pulses, the color of which changes regularly with time, are generated and applied to an object to be measured. A reflected light image of the chirped light pulses reflected from the object is acquired. Then, three-dimensional information of the object is acquired using two-dimensional information, color information represented by the reflected light image of the chirped light pulses, and the field of vision of the three-dimensional information to be acquired is enlarged. | 12-23-2010 |

20150283644 | SEAM WELDING APPARATUS, SEAM WELDING METHOD, ROBOT CONTROL DEVICE, AND ROBOT CONTROL METHOD - The seam welding apparatus includes a pair of rotating electrodes, an electrode supporting frame, a distance measuring means, and a controller. The electrode supporting frame supports the pair of rotating electrodes. The distance measuring means is provided on the electrode supporting frame and measures a distance to an edge of the steel plate. The controller controls the robot to adjust a running direction of the rotating electrodes so that a deviation comes into zero when a distance actually measured by the distance measuring means deviates from a predetermined distance. Thereby, it is accomplished that the seam welding apparatus is downsized as well as uninfluenced by the surface state and/or shape of workpiece (steel plate). | 10-08-2015 |

20090190668 | DIGITAL BROADCAST RECEIVING APPARATUS - A digital broadcast receiving apparatus receives a digital broadcast signal, which consists of layers each obtained by dividing a transmission bandwidth into a plurality of segments and combining some of the segments, and outputs images and/or sound from one of the layers constituting the received digital signal. This apparatus is characterized by comprising broadcasting format retention means (channel to broadcasting format correspondence table database) for retaining the broadcasting format, for each layer, of each broadcast station and switching means (layer switching means) for switching the output layer based on the broadcasting format, for each layer, of each broadcast station retained in the broadcasting retention means. Thus, this apparatus can output images and sound without interruption. | 07-30-2009 |

20140282782 | BROADCASTING METHOD AND BROADCAST SIGNAL RECEIVING APPARATUS - A broadcasting method and a broadcast signal receiving apparatus is provided wherein auxiliary information, such as video and audio data for supplementing broadcast information presented through a broadcasting network in an interlocked manner can be watched and listened to by the viewer. Broadcast information received from a broadcasting network is temporarily stored in a storage means of a broadcast signal receiving apparatus and a recording medium for storing auxiliary information used as a supplement to the broadcast information is mounted on the broadcast signal receiving apparatus. The broadcast information and the auxiliary information are then played back in an interlocked manner with a predetermined timing. As a result, a function to present information which cannot be accommodated in a broadcast frame and a parental function can be implemented. | 09-18-2014 |
