What are Motherboards?23 June 2021
The motherboard, also called the system board or mainboard, is one of the most basic and important components of a computer. The motherboard is generally a rectangular circuit board, on which is installed the main circuit system that composes the computer.
Hydrogen Fuel Cell: Features, Working and Applications21 June 2021
A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of electrolyzed water. Hydrogen and oxygen are supplied to the anode and the cathode respectively. After the hydrogen diffuses out through the anode and reacts with the electrolyte, electrons are released to the cathode through an external load.
Introduction to Optical Zoom and Digital Zoom19 June 2021
Optical zoom relies on the structure of the optical lens to achieve zoom, that is, the lens of the camera is moved to zoom in and out of the scene to be shot, and the resolution and image quality will not change. The greater the optical zoom factor, the more distant objects can be captured. Digital zoom uses the processor in the digital camera to increase the area of each pixel in the picture to achieve the purpose of magnification.
What are the Types of Camera Lenses?18 June 2021
The camera lens is an indispensable component in the machine vision system, which directly affects the quality of the image. Cameral lenses can be divided into short focal length, medium focal length, and long focal length. From the field of view, there are wide-angle, standard, and telephoto lenses. In terms of structure, there are fixed-aperture fixed-focus lenses and manual-aperture fixed-focus lenses, auto-iris fixed-focus lens, manual zoom lens, automatic zoom lens, auto-iris electric zoom lens, electric three-variable lens, etc.
Introduction to Wireless Router17 June 2021
The wireless router is a router with a wireless coverage function for users to surf the Internet. The wireless router can be regarded as a repeater, which forwards the broadband network signal from the wall at home to the nearby wireless network devices (laptops, wifi-enabled mobile phones, tablets, and all devices with WIFI function) through the antenna.
What is a Servo Drive?16 June 2021
Servo drive, also known as "servo controller" and "servo amplifier", is a kind of controller used to control servo motors. Its function is similar to that of frequency converters acting on ordinary AC motors, and it is part of the servo system. The servo drive is mainly used in high-precision positioning systems. Generally, the servo motor is controlled by three methods of position, speed, and torque to achieve high-precision transmission system positioning.
MEMS Basics: System Features and Classifications11 June 2021
MEMS, also called micro-electro-mechanical system or micro-system, refers to high-tech devices with dimensions of a few millimeters or even smaller. The internal structure of MEMS is generally on the order of micrometers or even nanometers. A micro-electromechanical system is a micro-device or system that integrates micro-sensor, micro-actuator, micro-mechanical structure, micro-power supply, micro-energy, signal processing and control circuit, high-performance electronic integrated device, interface, and communication.
How Fast is Wi-Fi 6?07 June 2021
Wi-Fi 6 ( IEEE 802.11.ax) is the sixth-generation wireless network technology and the name of the Wi-Fi standard. It is a wireless local area network technology created by the Wi-Fi Alliance based on the IEEE 802.11 standard. Wi-Fi 6 will allow communication with up to 8 devices with a maximum rate of 9.6Gbps.
What is UWB (Ultra-wideband)?04 June 2021
UWB (Ultra-wideband) technology is a wireless carrier communication technology, which does not use a sinusoidal carrier, but uses the non-sinusoidal narrow pulse of the nanosecond level, so the spectrum range is wide.
VRAM (Video RAM) Explained03 June 2021
VRAM (video RAM), also known as a frame buffer, is used to store the rendering data processed or about to be extracted by the graphics chip. Like computer memory, VRAM is a component used to store graphics information to be processed.
Bluetooth Explained: Characteristics and Applications02 June 2021
Bluetooth is a global specification of wireless data and voice communication, which is a special close-range wireless technology for setting communication environments for fixed and mobile devices. Bluetooth allows some of the current portable mobile devices and computer devices to connect to the Internet without a cable and can be wirelessly accessing the Internet.
What is a Wireless Network Adapter?01 June 2021
The wireless network adapter is actually a terminal wireless network device, which needs to be used for Internet access through the wireless connection network under the wireless coverage of the wireless local area network. With a wireless network adapter, it also needs a wireless network that can be connected, so it needs to be used with a wireless router or wireless AP.
