Title: Fiber optic sensor usable over wide range of gage lengths
Inventor: CHERPILLOD THIERRY
IPC: G01D5/353
Filed: 2002-02-21
Abstract: A fiber optic sensor includes two reflective elements in series. The first reflective element is formed as a partially mirrored surface on the end of a single-mode optical fiber lead which is bonded into a ferrule. A sleeve is used to join the ferrule to a second ferrule which is turn is bonded to a length of single-mode optical fiber. The second reflective element is a partially mirrored surface on the cleaved end of the second fiber. The second fiber may be affixed to or embedded in a structure to be monitored and changes its optical path length in response to a condition of the structure. Light introduced into the sensor is reflected from the first or second reflective element and thus follows two optical paths. The path length difference between the two optical paths is twice the optical path length of the second fiber.

Inventor: YAMAZAKI KOUICHI
IPC: G11B31/00
Filed: 2001-05-02
Abstract: La présente invention concerne un dispositif électronique, qui comprend une carte de circuit imprimé, une plaque de protection, placée sur ladite carte, ainsi qu'un régulateur à trois terminaux. Ce dispositif est pourvu d'un dissipateur thermique, qui est placé sur la face extérieure de ladite carte de circuit imprimé et est connecté audit régulateur à trois terminaux. La chaleur du régulateur à trois terminaux rayonne à partir du dissipateur thermique, ce qui permet d'empêcher la plaque de protection de chauffer. Ainsi, des éléments de dispositif électronique qui ne résistent pas très bien à la chaleur, tels que des unités de capteur optique, peuvent être montés directement sur la plaque de protection, de façon que la chaleur du régulateur à trois terminaux est efficacement dissipée et que la taille des dispositifs électroniques peut être réduite.

Patent CA-2396410-A1 (CA)
Inventor: HAMANAKA KENJIRO
IPC: G02B6/32
Filed: 2002-07-29
Abstract: An object beam divided by a light dividing means 12 is caused to enter a photo-refractive polymer layer 6 through an optical fiber 23. On the other hand, a reference beam divided by the light dividing means 12 is irradiated on the photo-refractive polymer layer 6 through a lens 13 from the opposite side. In this manner, the object beam is superimposed on the reference beam in the photo-refractive polymer layer 6 to provide an interference fringe or pattern. Since a photo-refractive polymer has a specific characteristic whereby the refractive index changes according to the intensity of irradiation light and the change is fixed after the irradiation light is stopped, a diffraction grating 5 corresponding to the interference fringe is recorded on the photo-refractive polymer layer 6. This diffraction grating 5 exhibits a specific characteristic whereby the object beam emitted from the optical fiber 23 is emitted in the direction of the reference beam.
