  • Patent number: 8244403
    Abstract: A visual navigation system and method based on structured light are provided. The visual navigation system at least includes at least one projector for generating a specific path pattern formed by structured light, and a visual server. In addition to facilitating the visual navigation system to detect an obstacle, the pattern formed by the structured light provides a specific path pattern followed by robots during the navigation. In the visual navigation method, when detecting the obstacle, the visual server routes a virtual path and issues a movement-control command to the robots, which in turn follow the virtual path. The present invention is capable of raising the accuracy for the robot navigation and reducing operation burden of the visual server by using the structured light to guide the robots.

  • Patent number: 7679748
    Abstract: The present invention discloses a coupled waveguide-surface plasmon resonance biosensor, comprising: a grating layer formed of a transparent material, the grating layer comprising a first periodic grating structure; a waveguide layer formed on the first periodic grating structure, the refractive index of the waveguide layer being larger than the refractive index of the grating layer; a plasmon resonance layer formed on the waveguide layer, capable of being optically excited to cause a plasmon resonance wave; and a ligand layer formed on the plasmon resonance layer; capable of being bound to react with receptors of a sample to be tested.

  • Patent number: 7187107
    Abstract: Provided is a closed-loop feedback control positioning stage comprising at least one block formed therein, a plurality of hinge mechanisms for attaching the block in the stage, at least one actuator formed in the block, the actuator adapted to bend for moving the block in at least one direction, and a plurality of strain gauges each attached in a corresponding hinge mechanism for measuring its strain. The invention can repeatedly position the block at the moved location for carrying out a highly precise positioning of the stage.
