System for protection of goods against counterfeiting

In order to verify the authenticity of manufactured goods, a smart tag is attached to the goods containing encrypted authentication information, such as a serial number, a description of the good's physical appearance or chemical decomposition, its color, or digital images of the good etc. The encryption procedure comprises public / private key encryption with zero-knowledge protocols. Zero knowledge protocols allow a smart tag to be authenticatable and yet be duplication resistant by allowing the verifying agent to convince him / herself that the smart tag is authentic without revealing its authentication information. The verification procedure can be done using a reader at a point of sale (POS) machine equipped with the appropriate public key and zero-knowledge protocols to decrypt the authentication information. A printed version of the serial number or other authentication information may be placed on the goods in human readable form to quickly verify the information electronically read from the smart tag. With the present invention, only the manufacturer can create such smart tags with the associated data thus making it virtually impossible to pass off a counterfeit good as authentic. In addition to authenticating counterfeit goods, the present invention can be used to detect authentic goods being sold in a parallel market.

Quick prototype design method and platform for gas path fault diagnosis for aeroengine

The invention discloses a quick prototype design method for gas path fault diagnosis for an aeroengine. The quick prototype design method comprises the following steps of: building an adaptive model of the engine; designing a gas path fault diagnosis logic in the full service life of the aeroengine, and implementing abnormal monitoring and gas path performance on-line estimation; and designing a quick prototype design platform for gas path fault diagnosis for the engine, and checking abnormal monitoring and gas path performance on-line estimation functions of the platform. The adaptive model of the engine is built by a compound interference method; an engine on-board adaptive model is used for estimating performance parameters; an engine adaptive base line model is used for monitoring abnormities and performs off-line period updating; and the quick prototype design method is used for checking the engine gas path fault diagnosis logic. The invention also discloses a corresponding quick prototype design platform. The method and the platform are relatively high in capacity of monitoring abnormities and estimating the performance in the overall service life of the engine and have great significance for shortening the development period and reducing the test risk and the test cost.

Under-actuated surface vehicle trajectory tracking control system based on self-adaptive fuzzy observer

The invention discloses an under-actuated surface vehicle trajectory tracking control system based on a self-adaptive fuzzy observer. A sensor module collects position and course information y of a surface vehicle and outputs the position and course information y to the self-adaptive fuzzy observer; the self-adaptive fuzzy observer receives output of a controller, obtains position and heading estimation, speed estimation, slow varying disturbance force estimation and unknown nonlinear term estimation (please see the expressions in the specification) and respectively transmits the position and heading estimation, the speed estimation, the slow varying disturbance force estimation and the unknown nonlinear term estimation to a trajectory tracking error generator and the controller; a guide system obtains expected speed and accelerated speed information in a hull coordinate system through calculation and respectively transmits the expected speed and accelerated speed information to the trajectory tracking error generator and the controller; the trajectory tracking error generator obtains error information of all states of trajectory tracking and transmits the error information to the controller; the controller calculates a longitudinal thrust and course changing torque control instruction of the current moment and transmits the control instruction to a thrust system, and the thrust system executes the control instruction. The under-actuated surface vehicle trajectory tracking control system can perform fast tracking under the conditions that only the position and the heading angle are measurable and a model has indeterminacy.

Continuous data protection method

The invention provides a continuous data protection method. Data can be recovered to any time point; data mounting in a short time can be realized; and the fast verification, write-in and immediate use of the data are realized. The method comprises the following steps that: initialization synchronization is executed at first; the initial state of production host block equipment is synchronized to a backup host; meanwhile, a data variation capturing module is started for capturing the data variation and transmitting the data variation to the backup host; the data variation is written into a mirrored volume; original data of a data variation address is written into a journal volume; the timestamp, the offset, the length and the storage address are recorded; and the recording of any data variation is realized. The reconfiguration of a virtual volume is used; the actual data access is redirected to the mirrored volume, the journal volume and a write time volume through a virtual volume index block; and the data read-out and the data write-in are realized. The data recovery is realized by using data read-out. Obsolete data can be deleted only through finding and deleting all of the journal volume and journal volume metadata files with the ending timestamp before the time point.

Physical examination information management system based on radio frequency identification (RFID) and cloud computing

The invention relates to the application field of the radio frequency identification technology and provides a physical examination information management system based on radio frequency identification (RFID) and cloud computing. The system comprises medical examinees, examination instruments, a relay server and a cloud server, wherein each of persons to be examined is provided with an RFID tag, and each of examination instruments is provided with an RFID reader. During examination, after the verification of RFID tags by RFID readers is successful, persons to be examined are examined by examination instruments, examination results are read to RFID tags through RFID readers and transmitted to the relay server through the internet by examination instruments, the relay server transmits identification information and examination information to a database of the cloud server through the internet and the identification information and the examination information are shared. By the aid of the RFID technology, the identification of persons to be examined is verified quickly. By the aid of the relay server, the examination data can be collected in real time. By the aid of the cloud computing technology, the information is shared and the management of users is facilitated.
