Abstract: A kitchen grip or implement for kitchen use is composed of a water-resistant and stain proof material having temperature control characteristics. Such a material forms the implement from at least one sheet having a textured, recessed or irregular surface providing a non-slip contact surface while the opposite surface of the sheet is composed of a close fabricated fabric which is affixed to the sheet of non-slip contact surface material. The fabric sheet may be a sheet of nylon/polyester composition which is affixed to the non-slip contact surface sheet which may be composed of a chloride rubber. The sheets are die cut to the shape of a useful implement such as a hand mitt, a trivet, a lid holder or the like. A two-piece implement such as a hand mitt requires that two sheets of the fabric and chloride rubber composition be sewn together by means of a zigzag lock stitch employing nylon thread. One surface of the mitt may include a cross-cut textured recessed imprint providing a non-slip or gripping contact surface while the opposite exposed surface of the mitt may take the form of the smooth nylon/ polyester fabric.

Title: Tunable optical add/drop device and method
Inventor: LIOU KANG-YIH
IPC: H04B10/43
Filed: 2001-01-10
Granted: 2003-03-25
Abstract: Data loss is reduced and bandwidth efficiency improved while tuning an optical add/drop device comprising a hitless wavelength-tunable optical filter. The hitless wavelength-tunable optical filter includes a broadband reflective surface and a tunable filter surface, the reflective surface and filter surface positioned adjacent to each other. Hitless tuning of the device is accomplished by changing the point at which an optical beam strikes the filter surface along a constant wavelength channel track whenever the beam is incident to the filter surface region. Realignment to a position associated with a new wavelength channel track is performed with the optical beam incident to the reflective surface region. Repositioning the optical beam to the filter region occurs at a location corresponding to the new wavelength to be added/dropped and subsequent optical beam realignment within the filter region is along the new wavelength channel track.

Abstract: L'invention concerne un nécessaire pour la préparation d'une greffe implantable, en particulier, d'une greffe osseuse composite implantable. Le nécessaire comprend un substrat stérile, biocompatible, poreux et un réceptacle configuré de manière à maintenir ledit substrat et à permettre l'écoulement, à travers celui-ci, d'une suspension cellulaire, en particulier d'une suspension de moelle osseuse prélevée par ponction. L'invention concerne également un procédé utilisant un tel nécessaire pour la préparation d'une greffe osseuse composite implantable. Le procédé consiste à préparer une suspension de moelle osseuse prélevée par ponction, et à faire passer ladite suspension de moelle osseuse à travers un substrat poreux, biocompatible, implantable, en vue d'obtenir une greffe osseuse composite présentant une population enrichie de cellules souches de tissus conjonctifs. La greffe osseuse composite préparée par le présent procédé renferme une population enrichie de cellules souches de tissus conjonctifs et un plus grand nombre de cellules souches de tissus conjonctifs par unité de volume que celui trouvé dans la ponction de moelle osseuse initiale. L'invention concerne en outre une greffe de moelle osseuse composite préparée conformément au présent procédé.

Abstract: Un interféromètre (1) est conçu pour former un premier diagramme de franges d'interférence comprenant au moins dix franges d'interférence. Une image dudit diagramme de franges d'interférence est enregistrée. Le trajet optique dans l'interféromètre (1) est perturbé, de manière qu'un deuxième diagramme d'interférences comprenant au moins dix franges d'interférence soit formé. Une image dudit deuxième diagramme d'interférences est combinée à l'image enregistrée du premier diagramme de franges d'interférences, de sorte qu'une autre image comprenant un diagramme de franges de moiré résultant de la ou des différences entre les premier et deuxième diagrammes d'interférences soit produite. La phase de combinaison consiste à soustraire (4) des images numériques. Différentes longueurs d'onde et interféromètres sont utilisés, dont, entre autres, des interféromètres de Michelson, de Fizeau et de Twyman-Green. Avec cette nouvelle approche, toutes les erreurs d'un système de mauvaise qualité et mal aligné, sont acceptées puis éliminées par le procédé de combinaison, ce qui permet la production d'un diagramme de franges de moiré. Ledit procédé permet aux système optiques à très grande ouverture pour interféromètres classiques et ceux utilisés en génie, d'être construits à partir de composants basiques et peu coûteux.

Granted: 2006-01-24
Abstract: In an all optical switch an imaging system is interposed between the micro lens array and the moveable micro mirrors of a MEMS device to which, or from which, the light beams are directed. This causes an image of the micro lens array to be formed at the MEMS device, or vice-versa, thus effectively eliminating the distance between the micro lens array and the MEMS device. The imaging system may be a telecentric system. The size of the arrangement may be reduced by compacting the optical path, e.g., using appropriate conventional mirrors, and/or employing folded arrangements, i.e., arrangements in which there is only one MEMS device stage that does double duty for both input and output through the use of at least one conventional mirror.  The overall system is arranged to account for any inversions introduced.

Abstract: Lors de l'utilisation d'écrous papillon vides par exemple, pour le montage et le démontage des abris d'auto ainsi que tout objet fixé par des écrous papillon vides, un problème survient. Il n'existe aucun outil pouvant s'installer sur une perceuse ou tout autre porte outil pour visser ou dévisser des écrous papillon vides sur les boulons retenant les pièces ensemble, nous devons donc les visser à la main ce qui rend moins efficace la solidité des écrous papillon vides, ou endommage les écrous papillon vides causant ainsi des risques de démembrement de l'objet lors de mouvement. Dans la présente invention l'outil facilite le vissage et le dévissage des écrous papillon vides en s'ajustant parfaitement à la forme des écrous papillon vides diminuant ainsi le temps de travail. Elle peut être adaptée aux différents formats de la tige de la perceuse ainsi qu'aux différents formats des écrous vides.
