1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
introduction
MEMS is a high-tech that has flourished on the basis of integrated circuit production technology and dedicated micro-electromechanical processing methods. Pressure sensors develop...[Details]
We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
At present, how various communication technologies will evolve after 3G is a focus of great concern in the industry. Especially for TD-SCDMA, whether it can achieve smooth evolution to the next gen...[Details]
In order to prevent the lithium battery from being damaged by abnormal conditions such as overcharge, over discharge, and overcurrent, a lithium battery protection device is usually used to prevent...[Details]
Introduction
my country's rapid economic growth is mainly due to the development of manufacturing and the acceleration of urbanization. However, urbanization cannot be achieved at the expense ...[Details]
LonWorks fieldbus technology is widely used, for example, in intelligent buildings, industrial control, environmental protection, etc. Echelon's LonWorks system has been used in the products of tho...[Details]
Current sensing in automotive applications includes controlling the current through solenoids and injectors. For example, during diesel injection, we rapidly increase the current to the induction i...[Details]
