Abstract: Systems, methods, and devices can be utilized to verify wireless local area networks (WLANs) using fingerprints. An example method includes identifying a received fingerprint comprised in an advertisement message that is received by a user equipment (UE) at a time and within a coverage area. A source of the advertisement message is determined to be a rogue WLAN by determining that the received fingerprint is different than a verified fingerprint transmitted by an authorized WLAN at the time and in the coverage area. The UE outputs an alert indicating the rogue WLAN.

Abstract: A system for starting a vehicle has a first apparatus having a microprocessor, a first data repository, a normally open electrical imposed between positive vehicle battery voltage and a keyed ignition switch, and a second electronic apparatus comprising a second microprocessor executing second coded instructions from a non-transitory medium, the second microprocessor coupled with the first microprocessor, a second data repository coupled to the second microprocessor and storing a list of identities of drivers authorized to operate the vehicle, and an input mechanism enabling a candidate driver to identify to the second microprocessor. The candidate driver identifies to the second microprocessor by the input mechanism, the second microprocessor, executing the second coded instructions, determines if the driver identity matches an identity on the list drivers authorized to operate the vehicle, and if so, causes the first microprocessor to close the normally open contact.

Abstract: The present invention relates to an expandable prosthetic implant device for engagement between vertebrae generally comprising an inner member, outer member, and gear member positioned coaxial with respect to each other such that the inner and outer members are moveable relative to each other along an axis. The gear member is axially fixed to the outer member and freely rotatable with respect to the outer member and the gear member threadedly engages a threaded portion of the inner member to translate inner member along the axis. The implant is configured to engage the vertebrae in a predetermined alignment and the gear member includes gear teeth exposed to the exterior and configured to be accessible by a tool member at a plurality of angular positions around the perimeter of the implant device.

Abstract: A method of firing a firearm includes compressing a main spring to rotate a latch pin lever; forcing a latch pin forward by the latch pin lever to force a cylinder forward toward a barrel; sealing or substantially sealing the barrel and the cylinder; and releasing a hammer to strike a cartridge while the barrel and the cylinder are sealed.

Abstract: A method includes receiving summary messages summarizing respective aggregated traffic metadata packets output from the at least one traffic management device and an engine. Each summary message identifies an origination pair having a traffic management device and an aggregation engine and a sequence number. The method further includes tracking per subinterval of a series of sub-intervals, highest and lowest sequence numbers and a count of summary messages received for each unique origination pair from the beginning of the subinterval. The method further includes accumulating, per interval, accumulated highest and lowest sequence numbers and an accumulated count of summary messages for each unique origination pair from the beginning of the interval and for all previous subintervals for tracking dropped aggregated traffic metadata packets for the interval.
