  • Patent number: 11046344
    Abstract: A gyroscopically-responsive power assisted moment arm is disclosed for use in connection with vehicles such as load carrying devices. A moment arm extends to a pivot point such that when a longitudinal force is applied at the moment arm, a sensor senses such force and outputs an energizing signal to a motor to drive a wheel. If a rotational or vertical force is applied to the moment arm, the motor need not be driven. According to the invention, therefore, a power assist can be provided to a user to drive a wheel in a desired direction of transport while not causing drive during tipping or unloading of the load carrying portion of the vehicle. Such an apparatus can be advantageously applied to a power assisted wheelbarrow, as one exemplary application.

  • Patent number: 10717493
    Abstract: A balancing transporter is provided to mitigate occurrence of undesired sudden turning and falling of a user by virtue of various mechanisms that control the source/cause of mistakes and implement post-mistake remedies. Two adjusting members are operated by the user for turning control in a manner that interference between operations on the adjusting members and on handles is prevented. Maximum allowance of difference between wheel speeds is introduced to prevent sudden turns due to inappropriate operation. A rotational interlock unit mechanically enables the adjusting members to rotate in opposite directions to prevent sudden turns. Shock absorption and balance compensation mechanisms are introduced to keep the balancing transporter from tilting.

  • Patent number: 10625806
    Abstract: A scooter has a load-carrying deck, a steering rod for steering a front wheel, two outriggers arranged on opposite sides to be pivotable between retracted stowed positions and extended support positions. Each outrigger has a wheel mounted movably on the outrigger to move between a stowed position and a ground-contacting support position. The outriggers when in their support position form a wider loading surface than the deck alone. A control arm is attached to the steering rod for movement between a folded/stowed position lying adjacent to the rod and an operating position extending forward from the steering rod. A sensor detects movement of at least a section of the control arm and, in response thereto, provides control inputs to an electric motor driving a rear wheel.

  • Patent number: 10433479
    Abstract: A knife drive assembly for use in a harvesting header is disclosed. The knife drive may be mounted near the center line of the cutter bar of the header. Mechanical power from the power unit behind the header (typically the combine power output shaft) may be translated for application to two knife assembly sections in the cutter bar at the front of the cutter table. Movement of the two knife assembly sections with this apparatus can be fully synchronized and 180 degrees out of phase, to maximize cutting effectiveness and minimize vibration of the header. The unitary drive assembly may allow for rapid repair and manufacture, and the size and weight of the knife drive assembly may represent a significant weight and balance advantage over the prior art.
