  • Patent number: 10780917
    Abstract: In a broad respect, vehicles that are capable of making a low- to zero-radius turn using the independent rotation of drive wheels and by turning the non-driving steerable structure or structures (such as wheels) with a steering input device (in some embodiments, the driving wheels also may be capable of being turned). This may be accomplished using a steering system, a speed control system and an integration device (together, a control system) that are configured to work together to provide correct steering in forward and reverse, and, in some embodiments, to reduce the speed of the outboard drive wheel of the vehicle when it enters an extreme turn under constant speed input. Different systems configured for use in such vehicles are included.

  • Patent number: 8011458
    Abstract: A ZTR vehicle includes true or proper ZTR steering in the forward and reverse directions. The vehicle has independently driven locomotive drives that drive the wheels to provide mobility and steering to the vehicle. A steering wheel is included that pivots one of two steering input members that rotate to independently shift the drive units. A speed and direction pedal is also included, which is communicated to provide direction and magnitude input to the drive units. The steering input and speed and direction inputs coordinate propelling the vehicle such the vehicle turns in the same direction when traveling forward as well as in reverse.

  • Patent number: 7365533
    Abstract: A system and method to detect angular rotation, linear displacement and/or surface deformations is presented. The method is based on the ability of a linear polarized light to interact with magnetic materials and to change its polarization angle due to Faraday effect. A basic structure of the system consists of a magneto-optic (MO) film with a two-domain structure and a single domain wall which are generated by gradient magnetic field produced by opposite polarity permanent magnets placed near the film. An AC magnetic field applied perpendicular to the MO film surface causes the magnetic domain wall in the MO film to oscillate at the same frequency. This leads to a detected output AC modulated signal. By measuring the temporal changes in this signal, information on angular rotation, linear displacement and/or surface deformation can be obtained.
