Patent number: 4915075Abstract: 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.Type: GrantFiled: March 20, 1989Date of Patent: April 10, 1990Assignee: Caterpillar Inc.Inventor: Richard L.

Patent number: 4499449Abstract: A speed setting device for an industrial sewing machine comprises a lever pivotally mounted at one end thereof on a stationary wall and adapted to be pivotally moved in response to the foot pedal of the sewing machine. An arm is pivotally mounted at one end to the stationary wall and operatively engaged with the lever so that they rotate in unison about respective pivot points thereof. The pivot point of the second member is between the lever pivot point and the engagement point between the lever and arm. Thereby, the arm is rotated through an angle greater than the angle through which the lever is rotated in response to the angular displacement of the foot pedal. An angular displacement sensor detects the angular displacement of the arm to generate a speed setting signal.Type: GrantFiled: June 7, 1982Date of Patent: February 12, 1985Assignee: Matsushita Electric Industrial Company, Ltd.Inventors: Nozomu Shinozaki, Takashi Dohi, Shinji Yamazaki, Shigeo Neki

Patent number: 4476415Abstract: A transducer for generating a feedback signal representative of the position of a movable member includes a signal generating mechanism for providing an electrical feedback signal representative of the position of the movable member. The signal generating mechanism includes a first shaft portion having a first longitudinal centerline and a drive mechanism having a shaft member coupled in driving engagement to the first shaft portion. The drive mechanism is adapted to be cable connected to one of a plurality of movable members having maximum travel spans different one from the other. The shaft member has a shaft longitudinal centerline which is concentric with the first centerline, the centerlines defining a first axis. An alignment mechanism is coupled to the drive mechanism and the signal generating mechanism and permits limited movement of the first axis with respect to a reference axis. The alignment mechanism thereby isolates the signal generating mechanism from misalignment reaction forces.Type: GrantFiled: December 6, 1982Date of Patent: October 9, 1984Assignee: Johnson Service CompanyInventors: Thomas O.
