1. Introduction RFID (radio frequency identification) is a non-contact automatic identification technology that emerged in the 1990s. It uses the characteristics of radio frequency signal prop...[Details]

Introduction Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]

Electronic systems are located at different points on the automotive power bus and therefore often need to operate under very stringent power requirements. These include load dump, cold crank, very lo...[Details]

1. Introduction Testing the temperature of steel billets before rolling is an important measure to ensure the quality of steel. Traditional manual testing is difficult to ensure product qu...[Details]

At very low temperatures, certain metals and alloys lose their resistance to electric current and become superconductors . Two parameters that are often measured are the transition ...[Details]

1. Disadvantages of choosing too high a voltage level Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]

Multimedia processors are often the most power-hungry devices in portable electronic devices. Common ways to reduce CPU power requirements are to reduce clock frequency or operating voltage, but th...[Details]

UDN2916LB is a two-phase stepper motor bipolar driver integrated circuit launched by SANKEN. It can drive dual-winding bipolar stepper motors and is particularly suitable for controlling dual-step ...[Details]

0 Introduction The load with impact (rapid change) power in the power system will cause the voltage fluctuation and flicker of the power grid, causing many electrical equipment to fail to wo...[Details]

This paper first proposed an elevator controller algorithm based on a finite state machine, and then designed a three-story elevator controller based on the algorithm. The correctness of the elevat...[Details]

According to the National Shipbuilding Industry Economic Research Center, the total shipbuilding capacity in my country last year was about 9×106t. The new ship orders exceeded 17×106t, accounting ...[Details]

1. Introduction Diesel engine test is the last key process in the diesel engine production process, which plays a very important role in the manufacturing quality of diesel engines. Its main c...[Details]

With the development of control, computer, communication and network technology, computer network integrated automation system has been widely used in modern industrial enterprises. The emergence o...[Details]

Conventional crystalline silicon solar cells are made on high-quality silicon wafers with a thickness of 350-450μm, which are sawn from pulled or cast silicon ingots. Therefore, more silicon materi...[Details]

In recent years, information technology based on microelectronics and computer technology has developed rapidly, and ultrasonic non-destructive testing instruments have also gained unpreceden...[Details]
