Abstract: The present disclosure includes a biomechanical weight-bearing crutch that may replace conventional crutches in use today. Unlike conventional crutches, the crutch of the present disclosure enables a user to immediately walk in a hands-free fashion. The biomechanical weight-bearing crutch is a form fitting device that can be worn inside or outside of the user's clothes. The movement of the crutch is automatically and synchronously performed as part of the gait motion, instead of today's cumbersome crutch motion where the users have to physically lift and move the crutch.

Abstract: Presently disclosed are systems and methods for location-based fuel distribution. One embodiment takes the form of a method of delivering fuel to a vehicle, including a fuel mobile app that registers the vehicle location and requests the fuel service, a gateway and authentication server, a location server, a dispatch server, a real-time fuel price server, a back-end server, and a database. These systems communicate with an application associated with a fuel service vehicle that then dispatches and delivers fuel to the vehicle. Additionally, the back-end server may be configured to bill a customer for the receipt of fuel.
