  • Patent number: 7675399
    Abstract: Disclosed is a device for the remote operation of the variable audio controls of floor-mounted audio effects devices, such devices typical of those used by performing artists on stage. The vast majority of devices of this type are operated by a foot pedal-controlled on/off switch and rotary operated potentiometer switch(es) to vary the audio output. The present inventive concept uses a variety of mechanical connectors, which couple the rotary switches of the floor device to a hand-operated controller mounted on a microphone or accessory stand. In this manner a performer is able to operate the effects device, with his/her hand, from a more natural standing position during a musical performance, rather than having to crouch down during said performance.

  • Patent number: 5793016
    Abstract: A foot control for a TIG welding machine utilizes a timing belt that is tensioned between a pedal and an enclosure. The timing belt meshes with a timing gear that is fixed to a rotatable shaft. Pivoting the pedal on the enclosure causes the timing belt to travel past and rotate the gear and shaft. A potentiometer on the shaft also rotates to control the power output of the welding machine. The belt is tensioned by a relatively weak spring in a manner that biases the pedal in one direction on the enclosure. A stronger spring biases the pedal in the opposite direction. The pedal is hinged to the enclosure by resilient tabs on the enclosure having bosses that engage holes in the pedal. The tab bosses can be depressed to disengage the pedal holes and enable the pedal to be removed from the enclosure. A heavy base joined to the enclosure has plates that lie alongside the enclosure tabs such that the tab bosses cannot be depressed out of engagement with the pedal holes when the base is joined to the enclosure.

  • Patent number: 4915075
    Abstract: Pedal mounted sensors are useful in motor vehicles for delivering an electrical signal correlative to the position of the accelerator pedal. The electrical signal is then used by an engine controller to regulate the amount of fuel supplied to the engine. Some pedal mounted sensors deliver analog signals which are subject to fault conditions which an engine controller can not distinguish from valid operating conditions. Remotely mounted sensors are difficult to install and repair. The subject invention is directed to pedal mounted sensors which have a potentiometer and circuit board hermetically sealed and mounted on a pedal for delivering pulse-width-modulated signal having a duty factor responsive to the pedal position.
