Abstract: A control device for an infinitely variable transmission includes a control lever that is movable along a guide slot and whose position within the slot indicates the commanded speed and direction. The control lever is moved forward from a zero speed position to a maximum forward speed position. Between the zero speed position and maximum forward speed position is a set point position corresponding to a set point speed. A set speed adjuster, such as a potentiometer, enables the operator to adjust the set point speed that is commanded when the control lever is placed in the set point position. The speed for positions of the control lever between the zero and the set point positions varies proportionally between zero and the set point speed. Likewise, the speed for positions of the control lever between the set point position and the maximum forward speed position varies proportionally between the set point speed and the maximum forward speed.

Abstract: A laser writing system includes a high reflector and an output coupler that define an oscillator cavity. A gain medium and a mode locking device are positioned in the oscillator cavity. A diode pump source produces a pump beam that is incident on the gain medium and an output beam is produced. A support holds a workpiece. Means are provided for directing the output beam across the workpiece.
