What is an Optical Sensor?19 March 2021
An optical sensor is a sensing device applied to measuring tools. The optical sensor uses the optical principle of the sensor for measurement, and in the process of using the optical sensor, because the measurement is not contacted, and it will not cause damage on the scene during the measurement. Therefore, the measurement of the optical sensor is very accurate, and it is hardly interfered by other factors.

What is a Synchronous Motor?16 March 2021
A synchronous motor is an AC motor that generates torque by the interaction of the excitation magnetic field supplied by a direct current and the rotating magnetic field of the armature, and rotates at a synchronous speed.) is an AC motor that generates torque by the interaction of the DC-powered excitation magnetic field and the rotating magnetic field of the armature, which rotates at a synchronous speed.
Apple M1 Ultra -- The Technology Behind the Chip Interconnection12 March 2022
Nowadays, manufacturing high-performance microprocessors are becoming increasingly tricky and expensive. That's why developers must choose complex packaging technologies and designs for performance-demanding applications. Apple acknowledges that it had to fuse two M1 Max system chips together to build the M1 Ultra processor. But it did not say it had to use one of TSMC's most advanced packaging technologies to build the M1 Ultra.
