Abstract: A radar wave sensing apparatus including a rotation element, a nanosecond pulse near-field sensor and a control unit is provided. The nanosecond pulse near-field sensor emits an incident radar wave and receives a reflection radar wave of the incident radar wave hitting on a surface of the rotation element to obtain a repetition frequency variation of the reflection radar wave corresponding to the incident radar wave. The control unit calculates a vibration of the rotation element according to the repetition frequency variation.

Abstract: A document feeder for multifunction printers or scanners offers high reliability and speedy paper-picking, -separating and -feeding functions. It comprises a picking module, a separating module and a feeding module. Since the three modules take turns to deliver paper, the paper can be picked at a lower speed, separated at a medium speed and then fed at a high speed. In addition, the separating module comprises a clutch. When the paper was fed by the feeding module, the clutch is activated to provide an interval between papers and to prevent papers from plucking.
