Abstract: A technique performs authentication. The technique involves performing, by processing circuitry, a set of authentication operations in response to a set of authentication requests, and updating a set of velocity metrics which identifies authentication performance for a set of authentication request sources that originated the set of authentication requests. The technique further involves, after updating the set of velocity metrics, receiving, by the processing circuitry, an authentication request from an authentication request source. The technique further involves providing, by the processing circuitry, an authentication result in response to the authentication request from the authentication request source. The authentication result (i) is based on the set of velocity metrics and (ii) indicates whether the authentication request is considered to be legitimate.

Abstract: A tool for trimming a bolt protruding through a nut includes a housing, a motor, a cutting wheel, and a wrench attachment. The cutting wheel is disposed within a first plane and is disposed at a first longitudinal position. The wrench attachment is disposed within a second plane spaced from the first plane. A wrench head of the wrench attachment is disposed at a second longitudinal position that is further away from the housing than the first longitudinal position such that the wrench head is longitudinally offset from the cutting wheel. The cutting wheel is configured to be longitudinally moved relative to the wrench attachment toward the wrench head. The tool may also include a bumper attachment that is interchangeable with the wrench attachment for use when cutting a frozen nut.

Abstract: A technique performs user authentication. The technique involves receiving, by processing circuitry, an authentication request which includes a set of authentication factors and which identifies a particular user. The technique further involves performing, by the processing circuitry, an authentication operation to generate an authentication result in response to the authentication request, the authentication result being based on (i) the set of authentication factors of the authentication request, (ii) a user authentication profile which profiles the particular user, and (iii) a lockout state identifying a lockout condition of the particular user which existed at the time of receiving the authentication request. The technique further involves providing, by the processing circuitry and as a response to the authentication request, an authentication action based on the authentication result.

Abstract: Authentication employs a classification that monitors content of authentication requests and results and assigns and records risk values identifying low-risk sources making normal authentication requests and high-risk sources making abnormal authentication requests indicative of fraud activity. Then for low-risk sources, a normal authentication process is employed having differential success/fail behavior exposing information about an enumerable system resource, such as a user account. Example differential behavior includes (a) granting access when a request identifies a valid user account, and (b) otherwise denying access, enabling an attacker to learn whether a guessed value identifies an existing account.

Abstract: A minimum diameter full-strength pipe connection of low cost is disclosed for all services.

Abstract: Conventional box and pin threads are machined with equal thread pitches and radial interference so when they are assembled, the pin elongates and the box contracts axially, causing a mismatch in the thread pitch which in turn, reduces sealing and best load transfer capacities between mating threads. This invention teaches how to improve both sealing and load transfer capacities.

Abstract: A long felt need for more reliable and safer pipe threads is provided which teaches (1) how to offset the mismatch of pipe threads that occurs due to elongation of the pin and contraction of the box during assembly; (2) how to prevent separation of mating pipe threads independent of radial thread interference; (3) a swaged box connection that is as strong as the pipe; (4) a thread that stabs easily without damage.

Abstract: A six wheel, three axle, bogie type main landing gear for an airplane is retractable as a unit and is provided with a rearward set of wheels or a forward set of wheels that is steerable with respect to the non-rotatable bogie beam. The set of wheels turns in response to steering of the nose wheel past a given angle. A wheel assembly is mounted for rotation with respect to a vertical shaft supported by a fork extending longitudinally of the beam, and a pair of hydraulic cylinders turns the wheel axles with respect to the beam.

Abstract: A hydraulic aircraft nose landing gear steering actuator includes a coaxial stator and rotor ring assembly mounted on the fixed outer cylinder of a nose landing gear shock absorber strut. Hydraulic vanes protruding radially inwardly and outwardly from the rotor and stator, respectively, form semi-annular pressure chambers between the stator and rotor rings which may be selectively hydraulically pressurized. A torsion link connects the steering actuator to the landing gear wheels. The steering actuator is capable of providing a constant steering torque to the landing wheels over a total steering displacement angle of approximately 150.degree..
