Abstract: A self-contained multi-station registration system for registering users at a point of registration is disclosed. The registration system provides a registration web page to registration stations at the point of registration. The registration system further receives registration information from the registration stations, wherein the registration information is associated with the users. The registration system then prints the registration information at the point of registration and saves the registration information for later use. Also, the registration system requires no access to public or corporate networks.

Abstract: A method for determining a road slope in an electric vehicle including determining the energy consumed or generated by a propulsion motor of the electric vehicle, determining the speed of the electric vehicle, and computing the road slope using samples of energy and speed of the electric vehicle. The method further including determining an optimal speed at which the vehicle should be driven for achieving maximum utility of energy.
