Abstract: A device for accurately measuring bending strain of a superconducting strand is provided. The bending strain precision measuring device includes a support frame. A driving mechanism is installed on the upper part of the support frame. An output end of the driving mechanism is sequentially connected with a weighing sensor and a pressure transmission module from top to bottom along the vertical direction. A bending strain module is installed on the lower part of the support frame. In a case that the output end of a driving mechanism moves downwards, the pressure transmission mechanism is capable of applying pressure to the superconducting strand placed on the bending strain module.

Abstract: Disclosed in the invention is a lithium battery production process, which comprises: through sequentially implemented processes of pre-compounding, winding for lamination, cutting, reclaiming material, continuously processing and assembling finished products, each electrode and separator are laminated, processed and formed, and finally assembled into a battery prefabricated product. The lithium battery production process is simple and efficient to implement, and it may realize continuous production of lithium battery products, thereby greatly improving battery production efficiency, and correspondingly simplifying the entire process flow to reduce the labor intensity of the staff. Also disclosed is a lithium battery production equipment for the above lithium battery production process.

Abstract: The present disclosure is to provide a synchronization method and device for a cloud storage system. The method includes receiving an operation request for a file object initiated by a client; calculating a hash value corresponding to the file object according to the operation request; acquiring the partition which the file object is stored according to the hash value; acquiring corresponding storage devices of each copy of the file object according to the partition which the file object is stored; initiating a write request to the storage devices to store the copies of the file object to the corresponding storage devices; and calculating a new hash value of the partition and transmitting the new hash value to an adjacent storage device. With the synchronization method and device of the present disclosure, it may reduce the network overhead and the synchronization delay.

Abstract: The disclosed subject matter relates to an architecture that can facilitate safety-oriented navigation through a local environment that presents emergency dynamics. The architecture can facilitate monitoring of deployed sensors constituting a sensor network, even for cases in which sensor locations are not known in advance such as for rapid or random deployment.

Abstract: A system and method for RFID privacy-preserving authentication is disclosed. The method first has a reader sending a request and a first random number to a tag. The tag then generates a second random number. A plurality of hash values are then computed at the tag. Each hash value uses the first random number, the second random number and at least one part of a key of the tag as inputs. The second random number and the computed hash values are then sent to the reader. Lastly, the reader identifies a validity of the tag from the received values. The hash values are all generated in parallel and are independent to each other.
