Abstract: A hybrid electric vehicle having alternate fuel sources is shown. The hybrid vehicle includes an AC/DC converter for storing a direct current voltage in a storage device such as a battery. A fuel converter converts a composition combustible fuel into a combustible fuel preferably hydrogen. The combustible material is stored in a combustible fuel storage device. The charging of a battery and the storage of the combustible fuel occur at prior to the starting of or the operation of the hybrid electric vehicle. A driving system includes a direct current motor and a combustible fuel engine. A control device enables the driving system to be powered by the direct current voltage or the combustible fuel. Preferably the combustible fuel is hydrogen. A hydrogen fuel cell is responsive to hydrogen to produce a direct current voltage for charging a battery or driving the direct current motor.

Abstract: A retractable step for use with a vehicle comprises a stepping member having a stepping deck, a first arm, a second arm, a motor and a stop. The first arm has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member. The second arm also has a first end pivotally attached to the vehicle, and a second end pivotally attached to the stepping member.

Abstract: The retractable foot gear 10 includes a sole 12 and a retractable wheel, ball, blade, or similar low friction element 16 which normally projects from a recess formed into the shoe's sole 12. The low friction element 16 retracts into a recess 14 when a predetermined amount of force is exerted on the low friction element 16. The low friction element 16 is additionally biased so as to automatically return to an extended position when the predetermined force is relieved. The retractable foot gear 10 assists persons with difficulty in walking, standing, or maneuvering. Moreover, the protruding low friction element enables one to slide one foot along a walking surface while minimizing the tendency of one to slip and fall.
