Abstract: TITLE INDEPENDENT STEERING AND PROPULSION SYSTEM FOR OFF ROAD VEHICLE ABSTRACT OF THE DISCLOSURE    A high mobility wheeled vehicle for transporting long loads, such as trimmed tree trunks or whole trees, over roadless terrain.          The vehicle has front and rear quad wheel assemblies pivotally connected to a centrally disposed elongated bed frame so as to permit lateral rotation of these assemblies about a roll axis disposed below and parallel to the longitudinal axis of the bed frame.  A linkage type roll control means interconnects the quad wheel assemblies and the bed frame to proportionately control the relative angular movement of the bed frame with respect to the quad wheel assemblies.  The roll control means includes a plurality of interconnected links plus a pair of power extensible links for selectively adjusting the steady state position of the vehicle bed relative to the quad wheel assemblies in either direction.    The quad wheel assembly incorporates a unique mounting for each of the wheels of the assembly which provides for individually controlled motors for driving each wheel, individually controlled brakes, and individually controlled, power actuated extensible links for steering each wheel.  Sensors are provided on each wheel assembly which generate signals proportional to the rota-tional velocity and direction of the wheel and proportional to the turning angle of each wheel.  A microprocessor receives all such signals and compares same with a desired turning angle and rotational velocity of the wheels in accordance with one of a plurality of modes of operation of the vehicle selected by the operator, and generates appropriate control signals to the individually controlled wheels to adjust the turning motion and the rotational velocity to that required to effect the desired movement of the vehicle.

Abstract: Abstract of the Disclosure There is disclosed herein a turn-signal system for vehicles wherein the turn-signal is automatically cancelled upon the steering device of the vehicle being returned to a predetermined position.  The system is particularly applicable to motorcycles.  The system includes a sensor which generates a signal representing a steering angle corresponding to the operation of the steering device, a noise eliminating circuit which receives the sensor signal and eliminates noises included in this signal as a function of running speed of the vehicle.  A peak hold circuit receives the output signal from the noise eliminating circuit and holds the peak value of the signal, and a comparator receives the output signal of the noise eliminating circuit as well as the output of the peak hold circuit, and compares these signals to generate a turn-signal cancelling signal when the steering device has been returned by a predetermined amount toward its normal position.
