Abstract: A lift and tow module for use with a trailer and method of towing a trailer with a truck. The module has an arm having a connection point for securing to a tow vehicle and a lift body having a connection point for securing the lift body to a trailer. The connection point comprises at least two connection mechanisms spaced apart on the main body for connection to corresponding mechanisms on the trailer. A support plate is extendable from and operably supported by the main body and the lift body is movable in reciprocal directions. Mechanical actuators are operably coupled to the body and the arm for controlling respective movement, which allows the module to jack up a trailer, connect to a trailer, and/or tow a trailer.

Abstract: Methods and systems are described for verifying an identity of a user through contextual knowledge-based authentication. The system described uses contextual knowledge-based authentication. By verifying an identity of a user through contextual knowledge-based authentication, the verification is both more secure and more intuitive to the user.

By verifying an identity of a user through contextual knowledge-based authentication, the verification is both more secure and more intuitive to the user. For example, by relying on confidential and/or proprietary information, the system may generate verification questions, the answers to which are known only by the user.

Abstract: Methods and systems are provided for an integrated low-profile reflex sight for a firearm. In one example, a system for a sight includes a housing including a collimating lens positioned before a front lens and an illumination assembly projecting a reticle on the collimating lens. A plurality of trajectory adjustment elements are coupled to the illumination assembly and a single side of the housing. The housing is shaped such that a slide of a firearm coupled to the sight may be removed without removing the sight from the slide, and a reticle of the sight and iron sights of the firearm may be co-witnessed.

Abstract: A sorting and sizing machine is disclosed having a frame comprising laterally spaced opposing guide rails. A plurality of sizing members are disposed between a top and bottom of each opposing guide rail. Within the opposing guide rails, individual members of a plurality of sizing brackets are disposed between individual members of a plurality of sizing spring members. A plurality of sizing rollers are disposed between opposing guide rails. Each of the sizing rollers is rotatably coupled to and disposed between an opposing pair of sizing brackets.

Abstract: A filter frame that includes a hinge structure for coupling a series of like filter frames together such that the series of filter frames may be folded together. Moreover, the filter frame includes a series of separable sub-sections that correspond to standard filter sizes. This enables an original filter frame to be "broken down" to a number of smaller standard sizes.
