The speed sensor has a mother body, a center position, a direction, and a range.
Figure 1 Speed Sensor
First, the sensor finds the closest a segment (or shell element) of sheet from the sensor center position. And a position of the segment (or shell element) is checked whether the position is in the range of sensor. If the position is in the sensor, the velocity of the closest position of the segment (or shell element) is computed and the sensor output is computed. As shown in Figure 1, if a sheet body passes to the range of the sensor, the sensor output can be computed from the following equation.
where,
: the result of sensor.
: the velocity of the closest
position of sheet segment (or shell element) in the range of the sensor.
: the velocity for the center
position of sensor.
: the specified direction of the
sensor.
