Powered single-wheeled self-balancing vehicle for standing user

A powered, gyroscopically balanced unicycle device to be used while standing, having leg contact surfaces which are made of a yielding, slightly soft material whose mild friction against the user's legs allows stable, precise control of the device without restraining the legs in any way. In one embodiment a single hubless wheel is driven by a friction drive mechanism which transmits torque from a motor through a drive wheel positioned below the foot platforms and in contact with the inner rim of the wheel. Various structures are provided for supporting the wheel and keeping it in place as it spins; absorbing small vertical movements of the wheel to prevent them from being transmitted to the foot platforms; enabling folding of the foot platforms; and facilitating carrying of the device by hand. Other embodiments are described and shown.

Bicycle user interface system and method of operation thereof

A bicycle is disclosed having a control system with a user interface and an active suspension system. The control system includes a one or more sensors arranged to measure and transmit a signal indicative of the terrain over which the bicycle is being ridden. The active suspension system includes a valve box that is fluidly coupled to each chamber of the lower cylinder. An orifice in the valve box is changed in size in response to a signal from a sensor associated with the front wheel that changes the response of the suspension system due to changing terrain conditions. The user interface includes a selection device mounted to the handlebars that allows the user to change parameters of the active suspension system during operation of the bicycle.

Bicycle damping enhancement system

A bicycle shock absorber for differentiating between rider-induced forces and terrain-induced forces includes a first fluid chamber having fluid contained therein, a piston for compressing the fluid within the fluid chamber, a second fluid chamber coupled to the first fluid chamber by a fluid communication hose, and an inertial valve disposed within the second fluid chamber. The inertial valve opens in response to terrain-induced forces and provides communication of fluid compressed by the piston from the first fluid chamber to the second fluid chamber. The inertial valve does not open in response to rider-induced forces and prevents communication of the fluid compressed by the piston from the first fluid chamber to the second fluid chamber.

Vehicles and methods using center of gravity and mass shift control system

InactiveUS7350787B2Eliminate inadvertent shiftsPassenger cyclesChildren cyclesControl systemGravity center
A center of gravity (C / G) control system for a vehicle includes sensors to measure the center of gravity shift and mass shift of the human body in relation to the vehicle, a controller to determine outputs, a dynamically adjustable vehicle system, and a power supply. The sensor measures the direction and rate of shift of the center of gravity and mass shift of the human and creates a representative input signal. The controller determines the appropriate outputs in response to the relative center of gravity shift data received. The dynamically adjustable vehicle system receives the controller output and performs the expected action.

Control of a personal transporter based on user position

A controller for providing user input of a desired direction of motion or orientation for a transporter. The controller has an input for receiving specification by a user of a value based on a detected body orientation of the user. User-specified input may be conveyed by the user using any of a large variety of input modalities, including: ultrasonic body position sensing; foot force sensing; handlebar lean; active handlebar; mechanical sensing of body position; and linear slide directional input. An apparatus that may include an active handlebar is provided for prompting a rider to be positioned on a vehicle in such a manner as to reduce lateral instability due to lateral acceleration of the vehicle.

Adjustable Bicycle Seat Post Assembly

An adjustable-height bicycle seat post assembly comprises a hollow seat post for supporting a bicycle seat slidably on plastic guides or shims inside a hollow tube. The hollow tube clamps into the frame of a bicycle. A mainspring forces the post upward, but a locking mechanism interconnects the post with the tube in various fixed positions relative to the tube. The locking mechanism includes a housing, which supports a plunger for reciprocating movement into and out of engagement with holes on the post. The locking mechanism is affixed to the outside of the tube to bear shearing forces on the plunger. An endcap on the locking mechanism and a topcap on the tube protect the assembly from foreign debris. The locking mechanism may be manipulated remotely using a magnetic switch assembly or manually using a mechanical assembly. A lost motion coupling is integrated into the locking mechanism and / or actuator assembly to enable the remote actuator to be moved or deployed while the latch remains trapped under the influence of a dominant shear load. The lost motion coupling is also effective to allow an operator to deploy the remote actuator at any convenient time prior to a desired change in seat height.

Bicycle rear wheel suspension system with controlled variable shock rate

The present invention is a bicycle including a bicycle frame and a rear wheel suspension system that is attached to the frame. The rear wheel suspension system includes a rear wheel swingarm and a shock absorber that is engaged to the swingarm to control the motion of a rear wheel of the bicycle. A change in the vertical wheel travel (ΔVWT) of the rear wheel is related to a change in the length of the shock absorber (ΔSL), providing a shock rate (SR) according to the relationship:SR=ΔSL / ΔVWT. The shock rate (SR) changes throughout the vertical wheel travel of the rear wheel, such that the change in the shock rate dSR / dVWT has a change in sign as the rear wheel travels through its vertical wheel travel. The shock rate may at first decrease in value and subsequently increase, or initially increase in value and subsequently decrease throughout the vertical wheel travel of the rear wheel. In various exemplary embodiments the swingarm may be attached to the frame at a single pivot point or through a linkage system.
