  • Patent number: 5865426
    Abstract: A human power amplifier includes an end-effector which is grasped by a human operator and applied to a load. The end-effector is suspended, via a rope, from a take-up pulley, winch or drum which is driven by an actuator to lift or lower the load. The end-effector includes a force sensor which measures the vertical force imposed on the end-effector by the operator and delivers a signal to a controller. The controller and actuator are structured in such a way that a predetermined percentage of the force necessary to lift or lower the load is applied by the actuator, with the remaining force being supplied by the operator. The load thus feels lighter to the operator, but the operator does not lose the sense of lifting against both the gravitation and inertial forces originating in the load. The operator has direct contact with the load (through the end-effector) there need be no switches, valves, keyboards, teach pendents, or pushbuttons in the human power amplifier to control the lifting speed of the load.

  • Patent number: 5855327
    Abstract: In a spinning reel for fishing, a fishline guide roller is rotatably supported on a bail support arm pivotably mounted on a rotor. The guide roller has a flattened shape such that a ratio of an axial length of the roller relative to a diameter thereof falls within 0.10-0.40. Further, the guide roller is formed with a narrow fishline guide groove so that a ratio of an axial length of the fishline guide groove relative to an axial length of the roller falls within 0.05-0.35. It is possible to make a fishline guide roller small in weight and size and to restrict axial motion of a fishline along the guide roller which, among other advantages, reduces line twist in the fishline.

  • Patent number: 5842684
    Abstract: A multi-speed winch is attached to a motor vehicle and is hydraulically powered by the vehicle's power steering system or other hydraulic source innate to the host vehicle. The winch operates in either a low-speed, high-torque mode for moving heavy loads, a high-speed, low-torque mode for quickly releasing or retrieving cable, a free-spooling mode for manually releasing cable, and a brake mode for holding the cable and load at a fixed position. The high-speed mode is enabled by coupling the drive shaft directly to the winch drum. The low-speed mode is enabled by coupling the drive shaft to the winch drum through a planetary gear assembly. In an alternate embodiment, high-speed mode is enabled by coupling the drive shaft to the winch drum through one of two planetary gear assemblies. Free-spooling mode is achieved by disengaging the drive shaft from the winch drum, and brake mode is achieved by engaging both the direct drive coupling and the sun and planet gear arrangement.

  • Patent number: 5833156
    Abstract: Backlash in a fishing reel is eliminated by automatically matching the reel discharge speed to the line speed. The drag on the reel is automatically adjusted so that the reel discharge speed does not exceed the line speed. The invention includes a reel, a mechanism for measuring the relationship between the line speed and the reel discharge speed, an electronically controlled braking device and a microprocessor for controlling the braking device in response to the relationship between the line speed and the reel discharge speed. When the reel discharge speed exceeds the line speed additional braking is applied. One alternative embodiment of the invention intermittently applies a very short pulse of braking action to the reel. The response to this pulse of braking action is detected and used to determine if the reel discharge speed exceeds the line speed.
