| 20090069833 | DISPOSABLE LANCET - The disposable lancet mainly contains a resilient needle body with two arms extended forward into a Y shape with a needle between the two arms. The two arms and the needle of the needle body are housed inside a sleeve member and the combination is slidably installed inside an enclosure. When the lancet is not yet used, the arms are blocked by two wedges of the sleeve member and the needle is hidden and protected inside the sleeve member. By compressing the sleeve member into the enclosure, the arms are forced out of the blockage and the needle body is driven forward by its resilience to penetrate through the sleeve member to draw blood. As the needle body retreats back into the sleeve member, the sleeve member is locked by the enclosure and cannot return to its un-used state. | 03-12-2009 |

| 20100183258 | Fiber sensing system with self-detection mechanism - The present invention discloses a fiber sensing system with self-detection mechanism which utilizes a central office to control secondary ring architecture formed by fiber sensor, remote node and optical coupler primarily. The secondary ring architecture is connected serially to form a primary ring architecture. The central office has a tunable laser light source that can deliver the light source to the fiber sensor. Since the fiber sensor has reflective ability, all light source signal sent by the tunable laser light source will be detected and measured by the fiber sensor. Thus central office can detect all signals reflected by the fiber sensor and produce a spectrum for analyzing fault point locations. The present invention can greatly enhance survivability and sensing capacity of all fiber sensors, so that when a fault point caused by environmental change within the fiber, it will not effect the overall operation of the sensing mechanism. The application of fiber sensor can also reduce cost and complexity of the overall fiber network topology. | 07-22-2010 |
