US Patent 7517163 Pressure pad engagement mechanism using sliding actuator

A slide track of a notched slider control can include a continuous path extending between two end points. A slider can be a graphical element able to move along the slide track. The end points can correspond to upper and lower extremes of a value range. Positions between the end points can represent values within the value range. The slide track can include at least one notch that is visually represented within the slide control as a deviation from a straight line segment having the two end points. The notch corresponds to a value within the value range. The notch can causes the slider to become fixed at a point along the slide track whenever a pointing device controlling the slider is moved in a direction of the deviation.
