A digital isolator module for high level common mode transient immunity is provided, comprising a transmitter circuit (TX), a receiver circuit (RX) and an isolation barrier which is connected there in between, wherein the transmitter circuit is electrically connected to a first ground voltage level and the receiver circuit is electrically connected to a second ground voltage level. The receiver circuit further comprises a resistance set, a high speed detector and a demodulator. By employing the proposed circuit diagram of the invention, interferences occurring at the common mode are suppressed and an RX output signal is synchronized with its input signal without having propagation delay.

The present invention discloses a serial transmission driving method, wherein a serial transmission driving device (STD) is connected with a first terminal (FT) and a second terminal (ST) of an equivalent load capacitor through a first differential bus (FDB) and a second differential bus (SDB). FDB and SDB are respectively connected with a high-potential terminal (HPT) and a low-potential terminal (LPT) through a first equivalent resistor and a second equivalent resistor. STD receives a trigger signal (TS) appearing during the transition between a turn-on signal (Ton) and a turn-off signal (Toff), generates a first potential (FP) and a second potential (SP) greater than FP according to TS, and respectively applies FP and SP to SDB and FDB. FP and SP fast change the potential of FT to be greater than that of ST. HPT and LPT maintain potentials of FDB and SDB until Toff ends.

A non-contact type torque and angle of rotation sensing device consisting of a magnetic member, sensing members and a computing unit for measuring a torque being applied to rotate a transmission member and the angle of rotation of said transmission member in a first axial direction is disclosed. The magnetic member defines a first center, and is mounted on and rotatable with the transmission member. The magnetic member deflects relative to the transmission member in a nonparallel manner relative to the first axial direction when rotating with the transmission member. Sensing members induce a magnetic field variation to output respective electrical signals that exhibit a phase difference there between. The computing unit receives and calculates the electrical signals of the sensing member to obtain the amplitude and to further translate the amplitude into torque value and angle of rotation.
