Abstract: Methods, apparatus, and systems for communication over a multi-wire, multi-phase interface are disclosed. A clock recovery apparatus has a plurality of pulse generating circuits, a logic circuit and a delay flipflop. Each pulse generating circuit generates transition pulses in response to transitions in one of three difference signals representative of a difference in signaling state of a pair of wires in a three-wire bus.

The delay flipflop is configured to respond to each pulse in the combination signal by changing signaling state of a clock signal that is output by the clock recovery apparatus. The symbols may be sequentially transmitted over the three-wire bus in accordance with a C-PHY protocol.

Abstract: The present invention discloses a method of measuring longitude deformation of blades. The radiation and rotation speed of the blade are collected by an optical probe and a synchronized rotation sensor. The stretch of the blade is able to be determined by the obvious change in the light intensity detected by the optical probe. The precision servo motor keeps driving the optical probe to move upward. The collected radiation is compared with the radiation collected on the previous point. The stretch of the blade is calculated based on position of the blade tip which is determined by the time when the high level radiation from the blade is disappeared. The longitude deformation of the blade is calculated by plugging the stretch into the deformation equation. Mapping the calculated deformation with the number of the blade calculated with rotation speed synchronizing signals to achieve the deformation of all the blades.
