Abstract: A motor control device controls driving of a motor, which outputs torque to a rack shaft as a load by rotation of a shaft fixed to a rotor. The motor control device has a rotation stress check unit for determining a rotation stress indicating a rotation stress, which is applied inversely from the load to a protection target member such as a shaft, bearing and oil seal related to the rotation of the shaft or torque transmission to the load. The rotation stress check unit determines the rotation stress is excessive based on that an absolute value of a rotation evaluation value exceeds a stress threshold value. The rotation evaluation value is a rotation angular velocity, a rotation angular acceleration or a related value corresponding to the rotation angular velocity or the rotation angular acceleration. The stress threshold value is set to be larger than an absolute value of an upper limit value realized in normal drive control.

Abstract: The Compound Torque Multiplying Lever Propelled Bicycle uses two force multiplying machines to generate a large amount of torque to be applied directly to the sprocket of the rear wheel. This machine uses a lever machine as a means of mechanical advantage and a two gear combination machine as a means of mechanical advantage. In this configuration, the input gear is always larger than the output gear or sprocket. Furthermore, because the load of each lever machine is moved away from the fulcrum and closer to the pedals, less material is needed to reinforce the lever machines from the inside; thus, they are lighter. Furthermore, because the sprockets used to increase torque and range are smaller in diameter, they are then lighter, which would result in a bicycle that is lighter, having consistent increased torque from pedal peak to pedal base with a substantial amount of range.

Abstract: Presented herein are adaptive power assist systems for manually-powered vehicles, methods for operating/constructing such systems, and motor-assisted, operator-powered vehicles with input torque filtering for adaptive power assist operations. A method for regulating a power assist system includes a vehicle controller receiving torque sensor data indicative of user-generated torque input. The vehicle controller then determines: if the torque input is less than a commanded motor torque generated by a tractive motor; and, if a calibrated motor decay time of the tractive motor is less than a scaled cadence time of the user's cadence speed. Responsive to both determinations being positive, the vehicle controller calculates a torque decay factor based on the current cadence speed, and modifies the commanded motor torque based on this calculated torque decay factor.

Abstract: A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and source.
