A secure system for authenticating the identity of ADS-B systems, including: an authenticator, including a unique id generator and a transmitter transmitting the unique id to one or more ADS-B transmitters; one or more ADS-B transmitters, including a receiver receiving the unique id, one or more secure processing stages merging the unique id with the ADS-B transmitter's identification, data and secret key and generating a secure code identification and a transmitter transmitting a response containing the secure code and ADSB transmitter's data to the authenticator; the authenticator including means for independently determining each ADS-B transmitter's secret key, a receiver receiving each ADS-B transmitter's response, one or more secure processing stages merging the unique id, ADS-B transmitter's identification and data and generating a secure code, and comparison processing comparing the authenticator-generated secure code and the ADS-B transmitter-generated secure code and providing an authentication signal based on the comparison result.

A system and method for verifying the face of a user using a light mask are provided. The system includes a facial feature extraction unit for extracting a facial feature vector from a facial image received from a camera. A non-user Gaussian Mixture Model (GMM) configuration unit generates a non-user GMM from a facial image stored in a non-user database (DB). A user GMM configuration unit generates a user GMM by applying light masks to a facial image stored in a user DB. A log-likelihood value calculation unit inputs the facial feature vector both to the non-user GMM and to the user GMM, thus calculating log-likelihood values. A user verification unit compares the calculated log-likelihood values with a predetermined threshold, thus verifying whether the received facial image is a facial image of the user.

A method of forming a joint between the ends of two fiber composite laminates (13,15) comprises cutting a first set of teeth (19) in the end of the first fiber composite laminate cutting a second set of teeth (21) in the end of the second fiber composite laminate, the second set of teeth being matingly aligned with the first set of teeth; spatially aligning the first fiber composite laminate and the second fiber composite laminate so as to produce a bond line (23) having a variable thickness therebetween, the thickness being defined as a marginal distance between the first set and the second set of teeth; wherein the bond line is thickest near the tips of the teeth and thinnest near the midpoint of the teeth; disposing an adhesive in the bond line; applying a cover piece (123a,123b) over at least one surface of the joint, the cover piece being adapted to provide a visual indication of a level of strain in the joint; and curing the adhesive.

The invention discloses a bearing disassembling tool with a hammering function, and relates to tools for disassembling bearings. The bearing disassembling tool is characterized in that the middle of across beam (6) is connected to the two sides of the upper end of an internal ribbed tube (24), upright rods (11) are arranged at the positions close to the two ends of the cross beam respectively, the upper ends of two vertical arms (10) are hinged to the two sides of the lower part of the internal ribbed tube respectively, the inner ends of two pushing rods (15) are hinged to the lower ends of the two vertical arms respectively, the middle parts of the two pushing rods are located in long round holes (16) formed in the lower parts of the two upright rods respectively, springs (12) sleeve theparts, located between the vertical arms and the upright rods, of the two pushing rods respectively, hook pieces (18) are arranged on the opposite sides of the lower ends of the two vertical arms, and the middle part of a screw rod (2) is located in inner threads (7) of the internal ribbed tube. According to the bearing disassembling tool, the two vertical arms are used for clamping a bearing, asmall hammer is used for auxiliarily hammering two hammering heads, and meanwhile, handles is used for controlling the internal ribbed tube and the screw rod to rapidly take down the bearing.
