Abstract:
Various methods are described for using a local trust level and/or a general trust level to control access of data in PSN. Any PSN user can select other users with at least a minimum level of local and/or general trust for secure communications. The users with a trust level below a minimum trust level cannot access the data sent from him/her. The general trust level is controlled by access keys that are generated and issued by a trusted server. The local trust level controlled access keys are generated by each PSN device. Each PSN device issues the corresponding personalized secret keys to those users that satisfy the decryption conditions related to local trust level evaluated by PSN user itself. Both sets of keys can be applied at the same time to secure communication data in PSN controlled by both the general trust level and the local trust level.
Abstract:
Embodiments of the present disclosure relate to substance detection technology, and to signal extraction circuits and methods for ion mobility tubes, and ion mobility detectors, which can solve the problem with the conventional technologies that it is difficult to design and manufacture the leadout circuit for the pulsed voltage on the Faraday plates. A signal extraction circuit for an ion mobility tube includes an DC-blocking module configured to remove a DC voltage contained in a voltage extracted, by a signal leadin terminal, from the Faraday plate, and to output, by a signal leadout terminal, a pulsed voltage contained in the voltage extracted from the Faraday plate. An ion mobility detector includes the signal extraction circuit for an ion mobility tube according to the present invention. A signal extraction method for an ion mobility tube includes extracting a voltage on a Faraday plate in the ion mobility tube, removing a DC voltage contained in the voltage extracted from the Faraday plate, and outputting a pulsed voltage contained in the voltage extracted from the Faraday plate. The present invention is used to extract a pulsed voltage from the Faraday plate.

Abstract:
The present invention relates to semiconducting compounds, materials prepared from such compounds, methods of preparing such compounds and semiconductor materials, as well as various compositions, composites, and devices that incorporate the compounds and semiconductor materials. The semiconducting compounds can have higher electron-transport efficiency and higher solubility in common solvents compared to related representative compounds.
Abstract:
A sample feeding device for a trace detector is disclosed. The sample feeding device comprises: a sample feeding chamber disposed in the sample feeding device to desorb a sample from a sample feeding member; and a valve assembly configured to fluidly communicate the sample feeding chamber with a drift tube of the trace detector during feeding sample. With the above configuration of the present invention, for example, the sensitivity of the detector can be increased by improving the permeation ratio of the sample. In addition, interior environment of the drift tube is isolated from exterior environment to avoid a drift region of the drift tube from being polluted. The important parameters, such as sensitivity, a position of a peak of a substance, a resolution, of the detector can be kept constant. As a result, operation reliability and consistency of the detector can be achieved.

Abstract:
If retrieved information from a storage area network resource does not enable simple and direct mapping of the respective unknown type of storage area network resource to a known type of storage area network resource with sufficient certainty (because the collection of data does not match any known unique groupings of data associated with known types of resources), then a mapping function attempts to automatically map the storage area network resource to a respective known type of storage area network resource. For example, the mapping function attempts to identify the specific identity of the storage area network resource in question. After repeating a process of mapping and determining identities of one or more different resources in a storage area network environment, an advisory process applies a set of configuration rules to identify whether an arrangement of resources will work properly.
Abstract:
A golf club head includes a golf club head body and a weight member. The golf club head member has a recession in which the weight member is mounted. The weight member is securely mounted in the recession of the golf club head body by a welding procedure that uses a welding material. The weight member is made of a material having a melting point higher than that of the golf club head body, avoiding melting of the weight member during the welding procedure. Only a portion of the golf club head body fuses with the welding material while using the welding material for proceeding with the welding procedure for the weight member.
