For more than three decades, Micro Electro Mechanical Systems (MEMS) have steadily transitioned out of research labs and into production forming a more than $10 billion market [1]. MEMS devices such as accelerometers, pressure sensors and microphones, to name a few, have seen immense utilization, pa ...

The concept of MEMS is attributed to Richard Feynman’s famous talk on December 29th, 1959 [2,3]. Dr. Feynman foresaw many aspects of future MEMS deve ...

台达的资料，给用的着的同学们。早期当各家 PLC 开发商纷纷建立自己的编程语言时，其各自不同的编程方式，对于用戶而言无疑是一个相当大的负担；有鉴于此，由国际组织 I.E.C.（International Electro-technical Commission）所制定与推动的 IEC 61131-3 标准便由此应运而生。其主要的特色在于统整各家的编程特点，并考虑用 ...

3-phase Sensor-less Fan Motor DriverAM2355NThe AM2355N is a 3-phase sensor-less DC fan motor driver IC. It senses the BEMF (BackElectro-Motive Force) of the motor in rotation and provides corresponding commutation current tothe motor. Rotation speed can be controlled by PWM input signal. The drivers ...
