Abstract: Embodiments of the present disclosure include a walker equipped with one or more sensors, an onboard controller, powered wheels and associated motor controllers. The walker can sense its distance from the user and activate the powered wheels when commanded by the controller. The controller can execute programming including an automatic feedback control algorithm that regulates the distance between the walker frame and the user. In this manner, the walker automatically follows the user, keeping the user from having to expend energy to pull the walker along. The walker can then be utilized by the user solely for balance and support.

Abstract: A system, device and method provide a glide kit that can attach to a conventional mortar round to create a glide-enabled round. The glide-enabled round can fit within a mortar tube. When the munition exits the mortar tube, it sequentially deploys wings and canards to initiate the glide maneuver and increase the mortar range. A state estimator subsystem can be employed with a canard control subsystem to actively guide the mortar to a fixed location. The combination of the estimator and canard control subsystems improves the tracking precision of the mortar round.

Abstract: Embodiments of an escort drone device, system and method provide one or more autonomous or semi-autonomous escort drones capable of being summoned by an individual to a first location, wherein the escort drone(s) includes a payload with threat deterring components and wherein the threat deterring components can be engaged by a remote operator at a different location from the first location. In embodiments, the system can employ intelligent mesh networking to allocate one or more escort drones to one or more specific locations.
