A vehicle power control that includes a throttle mounting portion and a throttle that is movably mounted to the throttle mounting portion and configured for manipulation and operation by a rider. The power control also includes a sensor in contactless association with at least one of the throttle and throttle mounting portion. The sensor is configured for sensing a position of the throttle with respect to the mounting portion, in the contactless association, and generating a signal based on the sensed position for controlling motive power of a vehicle.

Vehicle with contactless throttle control

A vehicle that includes a vehicle body and a vehicle support assembly. The vehicle body has a longitudinal axis and is configured for supporting a rider thereon. The support assembly includes first (A) and second (B) tilting wheels disposed respectively at different lateral positions with respect to the longitudinal axis, a tilt-mechanism () supportively associating the vehicle body from the tilting wheels to enable the vehicle body to tilt through a first tilt range with respect to a surface on which the tilting wheels are disposed, and a tilt-limiter () operably associated with the tilt-mechanism () to restrict the tilting of the vehicle body to less than the first tilt range, and releasable to allow the tilting through the first tilt range.

A vehicle frame that includes first and second frame portions. The first frame portion has a plurality of struts associated with each other to form a first framework. The second frame portion is associable with the first frame portion in a stiffening association for significantly increasing the stiffness of the first frame portion. The associated first and second frame portions are configured to support a rider sitting on the vehicle frame. The associated frame portions also define an interior cavity dimension for housing a component of the propulsion system for propelling the vehicle. The associated frame portions also comprise attachments for supportedly connecting two wheels of the vehicle, a seat disposed on the frame, and other vehicle accessories and systems.

A regenerative braking system for an electric vehicle having front and rear wheels, and includes a drive wheel, an actuating device, a regenerative braking control circuit, and a power electronics circuit. The regenerative braking control circuit includes a potentiometer ir transducer, a process sensor, and a microprocessor. The system applies a regenerative braking torque to the drive wheel when the rider commands regenerative braking, and the process sensors signal a drive wheel velocity greater than zero. The present invention also relates to a throttle for actuating regenerative braking and reversing feature.

Regenerative braking system for an electric vehicle

A two-wheeled electric scooter principally powered by batteries which together provide more than 100 volts. The scooter carries an onboard recharging system to replenish the battery supply. Accordingly, the onboard recharging system is not called upon to provide the main power source for acceleration and other operating conditions. A recharging system is implemented either as a fuel cell which trickle charges the battery, or an internal combustion engine which recharges the battery through a mechanical charging unit such as an alternator or generator. Regenerative braking is provided so as to further conserve energy by back driving the motor to recharge the battery pack during braking. Connections are provided for an external power source such as an AC outlet to be plugged into the scooter so as to provide an alternate mechanism to recharge the batteries.

The present invention discloses an electric vehicle frame having a lower portion and an upper portion. The lower portion includes a base and integral sidewalls. The sidewalls extend from the base to form an open cavity. The upper portion detachably joins to the lower portion such that the upper portion covers the cavity and forms a frame assembly which defines an enclosed chamber therein. The strength of the assembly is substantially greater than the strength of each of the portions prior to being joined. The lower and upper portions are formed of cast aluminum. The present invention further includes a method of assembling an electric vehicle, which includes using the frame and a plurality of subassemblies, and the electric vehicle formed therefrom, particularly in the form of a motor scooter.

Electric vehicle and frame therefor

An electric scooter employs an equalization circuit for charging a plurality of series connected batteries used to power the scooter. The equalization circuit has a number of cell circuits, each connected across the terminals of a corresponding battery. Each cell circuit includes two voltage detectors, a first implemented as a modular voltage monitor for detecting a low voltage across the battery terminals, and the second implemented as a Zener diode to detect a high voltage across the battery terminals. Both voltage monitors are enabled by an optocoupler switch. When the switch is turned on and either a low or a high voltage condition is detected, the cell circuit outputs a signal reflective of this condition through a second optocoupler. During a constant current charging phase, a high voltage condition causes the cell circuit to cause a portion of the charging current to bypass that battery, thus achieving equalization. A controller, which selectively enables the first optocoupler, also receives outputs from logic circuitry which tells whether any of batteries have low voltage and also whether the series connected batteries are fully charged. The scooter monitors the batteries for low voltage conditions during starting and also during quiescent states, i.e., low or no current draw, when it is being operated.

The invention herein is a method and apparatus for passively measuring and recording the thermal fluence from radiative heat sources. This is a non-electronic apparatus that includes a transducer whose sensing elements include a stack of thin sheets of stretched polystyrene. Each of the sheets of polystyrene are essentially opaque to infra-red radiation and upon exposure to a radiative heat source, soften and shrink as a function of the trapped bi-directional stresses within the sensing element material. These plastic elements integrate the time dependent thermal flux, i.e., they deform in direct proportion to the total incident fluence. This transducer is also direction dependent and has the ability to record the direction of the peak incident thermal fluence. Such a transducer is useful in mapping the incident heat input to large structures exposed to simulated nuclear and other types of intense thermal radiation.
