| 20120077501 | METHOD, DEVICE, AND SYSTEM FOR DERIVING KEYS - Method, device, and system for deriving keys are provided in the field of mobile communications technologies. The method for deriving keys may be used, for example, in a handover process of a User Equipment (UE) from an Evolved Universal Terrestrial Radio Access Network (EUTRAN) to a Universal Terrestrial Radio Access Network (UTRAN). If a failure occurred in a first handover, the method ensures that the key derived by a source Mobility Management Entity (MME) for a second handover process of the UE is different from the key derived for the first handover process of the UE. This is done by changing input parameters used in the key derivation, so as to prevent the situation in the prior art that once the key used on one Radio Network Controller (RNC) is obtained, the keys on other RNCs can be derived accordingly, thereby enhancing the network security. | 03-29-2012 |

An adjusting member is received into the bore, and a contact surface of the adjusting member engages the movable magnet. When the adjusting member is axially displaced, the contact surface causes a corresponding displacement of the movable magnet relative to the stationary magnet, eventually causing the magnetic flux field of each magnet to expand in a radial direction away from the longitudinal axis of each magnet. The stationary magnet and the movable magnet may be either axially-magnetized samarium-cobalt magnets or axially-magnetized neodymium magnets. | 03-03-2011 |
