摘要： The present invention is directed to sealable rock bolts (30) that prevent water leakage through the bolt, a kit containing portions of such bolts prior to assembly, installation, and use, and a method of using such sealable rock bolts. Such rock bolts are fastened in place in a roof, wall, or bottom of an underground region via pressure fitting or the like. The rock bolt contains a sealing unit (31) that contains a liquid water activated, expandable hydrophobic pre-polymeric resin (34). The sealing unit has side, top, and bottom portions that are degradable by water to permit the resin to expand upon contact with water and to seal the bolt to prevent water passage through the bolt.

摘要： The present invention describes a system and method for securely identifying and authenticating devices in a symmetric encryption system. An RFID tag can generate indicators using encryption state variables and a symmetric key. An RFID reader, after receiving the encryption state variables from the tag, may identify the tag by performing an exhaustive key search in a key database. Each key in the database may be tested by using the key and encryption state variables to perform an encryption operation similar to that performed by the tag. The result is then compared with the received tag indicators to determine if the tag has been identified. A rotor-based encryption scheme provides for a low cost key search while providing resilience against cloning, tracking, tampering and replay attacks.

摘要： An orthopedic implant system is disclosed for use in correcting or reducing the progression of scoliosis. The orthopedic implant system can be inserted laterally or posteriorly and comprises an elongated flexible member secured to a user's spinal column via a plurality of vertebral body screws. Typically, the width of the elongated flexible member is significantly wider than the height, creating a flattened cross-sectional aspect. The vertebral body screws comprise a screw head with a slot sized to accept the elongated flexible member, or a slot and space sized to accept an insert, and a screw base. Typically, the elongated flexible member is positioned within the slot and space via an insert, and is allowed to slide within the screw head or insert as needed, as the user moves. However, at the apex of the user's scoliosis curve, the elongated flexible member is fixed within a vertebral body screw head.

摘要： A dispensing device and method, especially adapted for use in sealing high pressure fluid leaks, is disclosed. Such use requires high pressure dispensing of sealant. Such sealants are formed by an exothermic reaction of at least two liquid substances that generates high pressures within the dispensing device. Such pressures could potentially harm the feeding system of the device due to pressure backflow. This problem is solved by providing a check valve (14) in the mixing and reaction chamber of the device to protect the feeding system. A static mixer is disposed within the chamber to enhance mixing and reaction of the substances.

摘要： The described system and method provide for an encryption and authentication technique that achieves enhanced integrity verification through assured error-propagation using a multistage sequence of pseudorandom permutations. The method generates intermediate data-dependent cryptographic variables at each stage, which are systematically combined into feedback loops. The encryption technique also generates an authentication tag with minimal post processing that is the size of the state. The size of the state is dependent on the number of pseudorandom permutations and the size of the LFSR. The authentication tag provides a unique mapping to the plaintext for any number of plaintext blocks that is less than or equal the size of the state. In addition to being a stand alone encryption algorithm, the disclosed technique is applicable to any mode that uses pseudorandom permutations such as, key dependent lookup tables, S-Boxes, and block ciphers such as RC5, TEA, and AES.
