Abstract: Systems and methods for linking an authentication account to a device may include processor(s) to maintain a plurality of authentication profiles, each authentication profile corresponding to a respective user and including at least one profile image, an immutable identifier, and authentication data used to authenticate the respective user. The processor(s) may receive a request including the device key, an immutable identifier, and a biometric image captured by a camera of a client device. The processor(s) may identify a subset of authentication profiles having respective immutable identifiers that match the immutable identifier from the request. The processor(s) may compare feature(s) extracted from the biometric image of the request to features extracted from the a profile image of the subset of authentication profiles, and link the device key of the client device with an authentication profile in a data structure to register the client device with the authentication server.

Abstract: Systems and methods for user verification may include processor(s) to maintain a plurality of authentication profiles for respective users, where each authentication profile includes profile image(s) and a device key linked to a respective client device. The processor(s) may receive a request including the device key of the client device and a biometric image captured during the session by a camera of the client device. The processor(s) may identify the authentication profile corresponding to the user based on the device key included in the authentication profile matching the device key included in the request. The processor(s) may compare feature(s) extracted from the biometric image to feature(s) extracted from the profile image(s), and store the biometric image in the authentication profile based determining that the feature(s) from the biometric image match feature(s) from a profile image of the authentication profile.

Abstract: Systems and methods for reversibly remediating security risks, which monitor a network or system for security risks, and upon detection of one or more of risks, apply a remedial action applicable to at least partially remedy or mitigate the one or more detected risk. The network or system is monitored for a change to the detected risk(s), and upon detection of a change to the detected risk(s), the applied remediation action is automatically reversed.

Abstract: A method for fueling a rail system fuel tender which comprises a chassis and one or more fuel containers, with each fuel container adapted to contain a quantity of pressurized fuel, where the method comprises storing fuel at a fuel source storage facility located distant from the fuel tender, delivering fuel by a fuel delivery means from the fuel source storage facility to the fuel tender, and fueling the fuel tender by a fuel filling means.

Abstract: A system for fueling a rail system fuel tender which comprises a chassis and one or more fuel containers, with each fuel container adapted to contain a quantity of pressurized fuel, where the system comprises a fuel source storage facility located distant from the fuel tender, a fuel delivery means for conveying fuel from the fuel source storage facility to the fuel tender, and a fuel filling means for placing pressurized fuel into the fuel tender.

Abstract: An improved rail system fuel tender for use with one or more railroad locomotives capable of transporting a plurality of fuel containers suitable for containing pressurized fuel and suitable for directly fueling the one or more locomotives. The improved fuel tender may be powered by the locomotives to increase tractive effort, and the fuel containers may be separately fillable and separately removable from the fuel tender.

Abstract: A road block for preventing unauthorized vehicles from entering a secured area comprises a pit, a span covering the pit, collapsible support members supporting the span at the trailing end of the plate with respect to the direction of vehicle access, devices for collapsing the support members, and a triggering mechanism for actuating the collapsing devices in response to the approach of an unauthorized vehicle.
