85 results about "Unique object" patented technology

The unique object method involves the distribution of an object that is different, interesting and easy to remember and that the person may want to have and carry with her. Next, in the survey questionnaire, we ask the participant if s/he has received that object and if s/he can show it at the moment of the interview.

Distributed file system and data access method thereof

The invention provides a distributed file system and a data access method thereof. The system comprises at least one client server, a metadata central server, at least one metadata server and at least one object server, wherein the at least one client server is used for receiving an access request from a client; the metadata central server is used for returning a currently available global uniquemetadata server identifier of the metadata server to the client server according to the access request of the client; the at least one metadata server is used for receiving file information transmitted according to the global unique identifier of the metadata server by the client server, and returning a currently available global unique object server identifier of the object server to the client server according to the file information; and the at least one object server is used for generating an access result in response to access contents transmitted according to the global unique identifier of the object server by the client server, and returning the access result to the client by the client server. The distributed file system and the data access method thereof greatly improve the reliability of the system at the same time of not influencing the data transmission efficiency.

Visual positioning system

A system determines an otherwise unknown position and orientation of a camera in a working environment, relative to an associated coordinate system, based on visually identifiable unique objects in images taken by the camera. The system utilizes a database that includes or may be updated to include position coordinates for unique objects of interest. The system identifies a plurality of objects within one or more images taken by the camera at a given location, and enters the database either to determine position coordinates for the respective identified objects or to add position coordinates to the data base for the respective identified objects, or both. The system may also update the database to include newly identified unique objects and objects that are altered between images, to determine position and orientation of the camera in a changing environment. Sensors may be included to add additional information relative to the position and orientation of the camera.

Device for characterizing unique objects

An examination method of a unique object including: forming a coherent radiation beam using a coherent source, illuminating the object by the coherent radiation beam, focussed using a focussing mechanism positioned directly in contact with the object or in a very close position to the object, and forming, using a detection mechanism, the optical Fourier transform image of the light diffracted by the object.
