The dominant mode of the coupled-cavity laser appears in one output port of the coupler, while the adjacent mode comes out from the other output port of the coupler. The resonant frequency interval of the sensing cavity is slightly larger or smaller than one half of that of the reference cavity. Part of the sensing cavity is the sensing section which is covered by an analyte. The refractive index change of the analyte will cause the lasing mode of the coupled cavity to switch to an adjacent mode, resulting in a π-phase change in the phase difference between the two output ports of the two resonance cavities. By applying the Vernier effect, the power ratio of the two output ports of the coupler will change and the refractive index change of the analyte can be derived.

20120164018 | METERING PUMP WITH SPECIAL-SHAPED CAVITY - The invention discloses a metering pump with a special-shaped cavity, which comprises a housing, a rotor and two cover plates. The housing is a cylinder with a special-shaped surface inner cavity, an inlet and an outlet, and the special-shaped surface inner cavity is formed by combining a circular arc surface with a non-circular arc surface. The rotor comprises a rotor body and two pairs of combined sliding plates, wherein the rotor body is a column body processed with a transmission shaft, a centering shaft and crisscross guide grooves, and the combined sliding plates are mounted in the guide grooves. The cover plates are flat plates processed with bearing holes. The two end surfaces of the housing are matched with the cover plates for constituting a sealed cavity. In the sealed cavity, the rotor is matched with the bearing holes on the cover plates through the transmission shaft and the centering shaft. External driving force couple is acted on the transmission shaft so as to enable the rotor to rotate. When the rotor rotates, the non-circular arc surface of the special-shaped surface inner cavity can enable the two pairs of the combined sliding plates to slide in a cross manner so as to suck in fluid from the inlet and press out the fluid from the outlet. When the rotor rotates one cycle, four standard volumes are formed in a cavity body and the equal quantity of the fluid flows by the cavity body when the rotor rotates every one cycle. The flow rate of the fluid is metered by counting the number of rotation cycles of the rotor. | 06-28-2012 |

20120066236 | METHOD FOR SEMANTIC SERVICE REGISTRATION AND QUERY BASED ON WORDNET - A method for semantic service registration and query based on WordNet is disclosed. The method includes the following steps: (1) semantic service registration: a service provider registers a service and uploads the Web Service Description Language (WSDL) document corresponding to the service, and a system parses the WSDL document to form a service description tree, then constructs a WordNet ontology tree according to the input of the service, performs a semantic annotation on the input/output of the service to form a Web Service Semantic Description Document (WSDL-S), and finally stores it in a register library; (2) semantic service discovery: a service requester inputs the information of service type, semantic information of the service input/output and other user-defined information to the register library to retrieve the services meeting the requirements; and (3) similarity sorting: the services meeting a certain threshold are sorted in descending order. The method has the advantages of the combination of WordNet ontology library and the semantic description language of WSDL-S, and definite semantic meaning. | 03-15-2012 |
