20110051123 | OPTICAL FIBER SENSOR, PRESSURE SENSOR, END EFFECTOR AND SENSOR SIGNAL PROCESSOR - An FBG (Fiber Bragg Grating) sensor is equipped with a plurality of stress detection sensors made up from optical fibers in which gratings that reflect light of a specified wavelength are arrayed, and a stress direction converter that converts stresses applied from the exterior into stresses of a direction in which the gratings are arrayed, and which transmits the stresses to each of the gratings. Consequently, the stress direction converter can transmit stresses, which are applied from a body, to a plurality of gratings. | 03-03-2011 |

20090147119 | OPTICAL SENSOR CIRCUIT AND IMAGE SENSOR - An optical sensor circuit has a photodiode PD, a MOS transistor Q | 06-11-2009 |
20090285521 | OPTICAL FIBER SENSOR - An optical fiber sensor which functions as a tactile sensor includes a plurality of shearing stress sensor sections including respective optical fibers and a plurality of gratings for reflecting light beams having predetermined wavelengths. The gratings are disposed in the optical fibers and arrayed along a plane parallel to the direction in which a shearing stress is applied from an object to the shearing stress sensor sections. The sensor also includes a perpendicular stress sensor section including an optical fiber and a plurality of gratings for reflecting a light beam having a predetermined wavelength. The gratings are disposed in the optical fiber and arrayed along a plane parallel to the direction in which a perpendicular stress is applied from the object to the perpendicular stress sensor section. Preferably, stress direction converting means such as elastic members for converting the direction of an applied stress are mounted on the optical fibers. | 11-19-2009 |
