Abstract: A foot pedal control for a surgical system, e.g., an ophthalmic surgery system, that adjusts to a number of different sizes of user's shoes. The foot pedal control has a treadle on which a user places his or her foot and a sensor that tracks the movements thereof. Adjustable lateral guides mount to the treadle and conform to both sides of the foot. The guides are shaped and positioned to conform to a wide variety of feet or shoes, and may easily be adjusted between users. A retractable heel stop converts between up for reference and down to enhance movement of the user's foot. A convertible handle may be stowed in a down position parallel to a base or pivoted up over the treadle for protection and ease of movement of the foot pedal control. The foot pedal control may be wireless and have various other electronic controls, and may have a dual-control treadle.

Abstract: A pedal system containing a right foot pedal, a left foot pedal and a motion inverter mechanism. The right foot pedal is moveable from a right foot pedal neutral position to a depressed acceleration position. The left foot pedal is moveable from a left foot pedal neutral position to a depressed braking position. The motion inverter mechanism operatively couples to the right and left foot pedals, for movement of the right foot pedal or the left foot pedal in an opposite direction to a raised position upon depression of the other of the right foot pedal or the left foot pedal. Also disclosed is a method of preventing concurrent depression of the gas and brake pedal. The pedal system disclosed can allow left foot braking and can also prevent concurrent depression of the gas and brake pedals, and hence, avoid stalling an automobile. The pedal system may also be installed with “drive by wire” type automobiles.

Abstract: A treading type vehicle driving device includes a substrate, a first transmission assembly, a second transmission assembly, a treadle structure, a gear assembly and a position limiting plate. The straight-cut gear A can move reciprocally along the trenches of the slant-cut gears C1 and C2 so as to drive the straight-cut gear A to engage with the straight-cut gear B2 of the first transmission assembly (treading forwards), or to engage with the straight-cut gear D of the second transmission assembly 2A (treading backwards). When the pedal is treaded forwards and backwards, the vehicle moves forwards rapidly with less power. The straight-cut gear A will separate from the engagement of the straight-cut gear B2 or straight-cut gear D of transmission assembly since the teeth trench of the slant-cut gears moves on the slant-cut fan gear(forwards is C1 and backwards is C2); thereby, wheels rotate continuously.
