  • Patent number: 6147590
    Abstract: A treadle assembly provides an electrical signal to an electronic controlled engine. The assembly includes a treadle suspended in the operator compartment. The treadle is pivotally mounted to a lever which pivots in response to the operator imposed depression of the treadle which, in turn, actuates a rotatable gear. The gear is in operative engagement with the potentiometer and an electrical signal is sent to the engine in response to rotation of the gear. The lever and gear are preferably interconnected by a slot and pin connection to reduce manufacturing costs associated with the components and accommodate misalignment during assembly and tolerance stackup associated with assembling individual components together.

  • Patent number: 5712460
    Abstract: A multi-function control system to control a variety of operations associated with a powered surgical device such as an arthroscopic surgical shaver. The system has an ergonomically designed foot switch which has a plurality of discrete force sensitive transducers arranged in an arcuate pattern. The transducers have no moving parts and have a force sensitive element which produces a variable output which is a function of the force applied by a user. The foot switch is used in conjunction with a control console which enables a user to adjust the force sensitivity threshold of the transducers. The foot switch additionally has physically discrete and tactilely sensible areas enabling a user to activate selected functions with a minimal amount of foot movement.

    Abstract: An operator controlled variable electrical power delivery console and foot pedal controller are provided. The variable electrical power delivery console is designed to supply power to universal motors that are subjected to fluctuating loads that impact the performance of the motor. The invention combines two types of solid state electronic circuits including a selectable power booster circuit that responds to load changes that enables a motor to operate at high torque and another selectable solid state electronic circuit which allows the motor to operate at high speeds and lesser torque demands. The invention includes a selectable auxiliary foot pedal controller that is operator selectable for use with either of the two types of electrical circuits.

    Abstract: A variable power foot pedal controller for controlling electrical power to universal motors and which contains solid state circuitry that boosts the power to accommodate high torque performance from the motor in response to load changes. The foot pedal controller includes a steel cable linkage arrangement that interfaces with a slide type control variable resistor that provides the linear motion control for varying the resistance that biases the solid state circuitry that boosts the power being delivered to the motor. The linkage arrangement allows operator incremental power delivery control by manipulating the slide variable resistor and further activates and deactives switch elements according to positional states of the linkage to energize the solid state circuitry or bypass the solid state circuitry.

  • Patent number: 4281310
    Abstract: A round foot controller has a molded cover 75 attached to a molded base 11 by interengaging projections 79 and 16 extending in opposite directions toward each other from the rims of telescoping walls 77 and 13. The wall 77 is near the perimeter of the cover and is concentric with another wall 76 that surrounds the wall 77. The wall 13 concentrically surrounds another wall 14 in the base. The base has openings 96 and the cover has corresponding openings 97 left by the respective molds that form the undersides of the projections 16 and 79. The double-walled structure of the cover telescoping with the double-walled structure of the base prevents inadvertent access to the electrical components in the foot controller. However, the resistence of a variable resistor 21 or 103 in the controller, can be varied by pressure on any part of the cover 75.

  • Patent number: 4233587
    Abstract: A variable resistance controller for electrical braking systems and the like wherein the form on which the resistance wire is wound has spaced apart flats into which some of the coils are drawn during winding. This arrangement provides alternate lands and depressions over which a leaf spring type contact rolls. The preferred arrangement has only two coils per land to give increased contact pressure of the leaf spring therewith and to provide predetermined incremental increases in electrical output as the leaf spring rolls from one land to the other. In the preferred embodiment, the spacing of the lands is arranged so that the electrical output is proportional to the hydraulic actuating pressure.The preferred embodiment also includes a diode connected between the output of the controller and ground through a fusible link to permit the collapsing magnetic field of the controlled braking electromagnets to draw current through the diode on deactuation of the unit to bypass the wound resistor.
