People in Ginza basically sit in front of computers every day. When they get off work, they feel their eyes are extremely dry. What can you do to fight against radiation or long-term sitting in the of...
[table=98%] [tr][td]I am going to make an adaptive power supply recently. I need to make a 12V power supply to power the system chip for 12V battery and 24V battery. When the 12V battery is discharged...
It is customary to connect a 120Ω resistor between the RS485 interface AB and the CAN interface H and L. The warehouse only has 100Ω. Can 100Ω be used instead of 120Ω?...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
1 Overview
Drugs are like a "double-edged sword". They can treat diseases but can also cause serious adverse consequences. The dual nature of drugs depends on whether they are used rationally....[Details]
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
1 Overview
The BP01 pressure sensor is specially designed for monitoring blood pressure and is mainly used in portable electronic sphygmomanometers. It uses a precision thick-film ceramic chip and...[Details]
Emulation Features
Emulation provides a set of standard operations for integration and debugging. Some of its main features are as follows:
BreakpointsA

Portable devices with audio functions (such as portable media players and multimedia mobile phones) require long audio playback time, that is, long battery life. To extend the battery life of port...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m～1kHz), audio (20Hz～20kHz), video (20kHz～10MHz), radio fre...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
Among the many candidate standards for China's mobile TV, the CMMB standard proposed by the Broadcasting Science Research Institute of the State Administration of Radio, Film and Television is aime...[Details]
Power semiconductors and reactive components (capacitors and inductors) are ubiquitous in today's electrical equipment. In normal operation, they can cause two undesirable side effects on the AC line ...[Details]
1. Introduction
Rolling bearings are the most widely used general mechanical components in various rotating machines. Whether their operating status is normal often directly affects the perfo...[Details]
Introduction
As a kind of biometric identification, fingerprint recognition has incomparable advantages in identity recognition over other means: human fingerprints are unique and stable; wit...[Details]
Anyone who has owned a laptop computer will have noticed that when running on battery power, their portable device behaves differently than when running on AC mains power—the display dims, the proc...[Details]
Abstract:
This paper introduces the excitation system designed for 3/3 phase double winding induction generator, which is composed of DSP and FPGA. The interface circuit of the control sys...[Details]
