Recently, the team of academician Du Jiangfeng of University of science and technology of China has realized the room temperature solid-state spin programmable quantum processor for the first time by using the electronic spin and nuclear spin in diamond as two quantum bit systems. The researchers use green laser pulses to realize the initialization and […]

Application and principle analysis of intelligent water sensor
Water damage is one of the most expensive family insurance claims and the main cause of housing losses. However, the use of intelligent water sensors can reduce the impact of sudden water leakage and reduce losses. It can easily solve the problem of water leakage by sending you an alarm notice when it detects a […]
Which functions of embedded design software are more important
No matter what industry you are in, the competition is very fierce. Similarly, as an embedded software developer, sometimes it needs to bear great pressure, not only to complete the work faster than before, but also to be more effective than before. This means delivering software with higher performance and fewer “errors.”. Your ability to […]
Design of precise refueling system based on PIC Single Chip Microcomputer
I. Introduction At present, energy has become a bottleneck restricting the development of many countries, especially in the developing countries. The phenomenon of energy shortage is gradually emerging, and the competition for oil resources among countries in the world is increasing, even leading to local wars; As the largest developing country, China must strengthen the […]
Vishay releases High Performance CMOS analog switch with new technology
Vishay intertechnology, Inc. announced the launch of a new ± 15V precision single chip 4-way single pole single throw (SPST) CMOS analog switch with 1.5 Ω low on resistance – Vishay silicon dg1411, dg1412 and dg1413. Today’s device uses a new analog process, with a turn-on resistance of only 1.5 ohms. Compared with the previous […]
Gpu-z releases the latest version of 2.28.0 and supports a number of old ATI graphics cards
Gpu-z, a necessary tool for video card detection, released the latest version of 2.28.0 today. This upgrade is not large, but it’s very surprising that it also reminds me of a batch of old ATI video cards. The new version first fixes the core frequency identification error of the old ATI graphics card, and adds […]
What are the requirements of power system for circuit breakers
Control requirements of power system for circuit breakers 1. Closing and tripping are designed according to short-time energization; 2. The circuit breaker can be controlled manually by using the control switch; 3. All devices shall be equipped with electrical locking devices to prevent the short circuit breaker from tripping; 4. Position status monitoring; 5. There […]
Samsung launched T7 touch mobile SSD with up to four fingerprints
Generally speaking, there are only two things to improve SSD: speed and storage capacity. Obviously, it’s a little boring. At CES 2020 recently, Samsung announced a T7 touch external SSD which is very interesting. In addition to the conventional transmission improvement, it also added a fingerprint reading module to protect files. Samsung said that the […]
Analysis of the causes of PCB deformation
When the circuit board is reflow welded, it is easy to bend the board. If it is serious, it will even lead to empty welding of components and standing of monument. How to overcome it? 1. Damage of PCB board deformation In the automatic surface mounting line, if the circuit board is not flat, it […]
Simple implementation of a fully integrated 4-wire RTD temperature measurement system suitable for high-precision measurement applications
Author: Thomas brand, field application engineer, ADI company For a variety of products, the manufacturing process requires highly accurate and reliable temperature measurement technology. Temperature is usually measured by direct contact with the sensor, for example by immersion in a liquid or by contact with the surface of the machine. In addition to thermistors and […]
