Abstract: A portable compression device for compressing at least a portion of a mammal's limb is provided. The portable compression device can use mechanical compression to apply an external pressure to the portion of the limb to thereby propagate blood flow return in the direction of the mammal's heart. In at least one embodiment, the portable compression device can accomplish this mechanical compression through the use of at least one frame, actuator, drum, and flexible elongate member. The actuator can move the drum between a first position and a second position. The flexible elongate member can be engaged with at least a portion of the drum and can at least partially circumscribe a portion of the limb of the mammal, such that the movement of the drum between the first and second positions can apply tension to the flexible elongate member to thereby apply a compressive force to the limb.

Abstract: Steering mechanism that increases adjustability. The steering mechanism can have different gear ratios between the input rotation from the user and the output rotation on the drive wheel. The steering device will allow users to employ a pushing or pulling motion for steering instead of pushing to turn in one direction and pulling to turn in the opposite direction. Users with weaker torso strength may not be able to maintain their balance when they pull on a steering tiller. Allowing users to choose the type of motion for steering, and to supplement one motion with the other, creating flexibility and support for users with various abilities. Lastly, the steering system should not impede a user transferring into and out of the personal vehicle.

Abstract: A personal vehicle comprises a frame with a seat, two large, non-drive wheels connected by an axle at one end of the frame, an elongated swing arm attached to the axle, a pair of caster wheels connected to the frame opposite the large, non-drive wheels and a main drive wheel mounted to a fork and connected to the swing arm. The main drive wheel is located central the vehicle frame, intermediate the frame sides and intermediate frame front and rear sections.
