  • Patent number: 10729066
    Abstract: A self-propelled machine includes a drive motor, a handle having two grips, an electromechanical converting device, and a speed adjusting element configured to move relative to the handle to adjust a rotational speed of the drive motor and configured to be operated by a user when the user holds one of the two grips with a single hand. The speed adjusting element is disposed between the two grips. The electromechanical converting device is configured to convert a positional change of the speed adjusting element into an electrical signal for adjusting the rotational speed of the drive motor. The speed adjusting element is movable between a first position and a second position. The rotational speed of the drive motor when the speed adjusting element is in the first position is greater than the rotational speed of the drive motor when the speed adjusting element is in the second position.

  • Patent number: 9365228
    Abstract: In one embodiment, a coast control system, or dead-man brake inhibitor, is associated with a tiller arm that is used for steering a vehicle. A spring acts upon the tiller arm when an operator releases a control handle attached to the tiller arm to move the tiller arm to a braking position which causes an electronically or mechanically actuated brake to be applied. Before releasing the control handle, the operator may actuate the coast control system to inhibit movement of the tiller arm towards the braking position when the control handle is released. The operator may vertically reposition the tiller arm while the coast control system remains actuated by overcoming the inhibiting force applied by the coast control system when the tiller arm is moved toward the braking position and by overcoming the spring acting on the tiller arm when the tiller arm is moved away from the braking position.

  • Patent number: 8467937
    Abstract: A power steering assist system for a hand-steered pallet truck includes a joint assembly having a pivot joint, handle biasing mechanism, and a torque sensing arrangement. The pivot joint includes a pair of needle bearings and pivot pin disposed within a pivot block that provides a flexible connection between a handle and a tiller arm. The handle biasing mechanism includes a cantilevered beam spring and two cam rollers that resists an operator steering force applied to the handle and further, centers the handle with respect to the tiller arm after the force is released. The torque sensing arrangement includes a magnet and a non-contact magnetoresistive (MR) sensor that measures movement of the handle relative to the tiller arm which is used to determine operator steering intent, i.e., the amount of steering force applied to the handle. The MR sensor provides accurate torque measurements regardless of the angle of the tiller arm.

  • Patent number: 8452464
    Abstract: A materials handling vehicle automatically applies a steer correction maneuver if an object is detected in a steer bumper zone in front of the vehicle. A controller detects whether an object is in front of the materials handling vehicle and automatically determines whether a steer correction maneuver should be to the right or left of the traveling direction of the materials handling vehicle. The materials handling vehicle automatically steer corrects the vehicle, e.g., at a determined steer angle that is opposite the direction to the detected position of the object, and accumulates the distance traveled by vehicle while steer correction is being performed. The vehicle then automatically counter steers the vehicle, e.g., by a determined steer amount, in the opposite direction as the steer correction for a percentage of accumulated steer distance traveled. After performing the counter steer maneuver, the vehicle may, for example, resume a substantially straight heading.

  • Patent number: 8380379
    Abstract: The present invention discloses a walking assistive system comprising a motion module, a current detecting module and a central control module. Each motion module includes omni-directional wheels, motors, shaft encoders and servo controllers. The omni-directional wheels are connected to and driven by the motors. The motors are connected to the shaft encoders, and the rotation speed values are generated corresponds to the rotation speed of the motors by the shaft coder. The servo controllers connected to the shaft encoders and the motors receive the rotation speed values and control the motors. The current detecting modules connected to the motors detect the current of the motors and generate current values correspondingly. The central control module connected to the motion control module and the current detecting module controls the platform compliant motion control modules according to the rotation speed values and the current values.

  • Patent number: 8333257
    Abstract: Systems and methods for moving objects facilitate quick and inexpensive relocation of the target objects. Operator safety is enhanced by eliminating the need to apply manual force to urge a target object into motion, and by inclusion of features such as automatic braking responsive to motor cut-off. Through use of the present system, a user may move a target object, for example a trailer intended for use behind a vehicle, into and/or out of a storage location in a simplified and more efficient manner.

  • Patent number: 8235152
    Abstract: A tow apparatus for moving an aircraft comprising a frame, a drive member, a contact wheel configured to engage with a nosewheel tire of an aircraft, a transmission portion, a shaft engageable with a nosewheel tire of an aircraft, and a torque arm rotatably supported by the frame. The transmission portion can be configured such that the drive wheels transfer and increase a rotational force produced by the drive member to the contact wheel. The shaft can be movable between a first position and a second position relative to the contact wheel so as to bring the contact wheel into contact with the nosewheel of the aircraft. The torque arm can substantially prevent the rotation of the tow apparatus relative to the nosewheel assembly of the aircraft when the torque arm is engaged with the nosewheel assembly of the aircraft. The drive member can have a portable power source.
