I once connected a 5.1V ZENER in parallel with the 3V LDO output for protection, and found that the output was pulled down to 2.3V.
Reason: I am designing for low power consumption here, the input cur...
A ventilator is an instrument that can replace or assist a person's respiratory function. It is suitable for artificial respiration of patients with respiratory failure or even respiratory arrest. I...[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]
Implantable Cardivoerter Defibrillators (ICDs) have been in common use for several years. ICDs apply a high voltage pulse between two electrodes connected to the heart, which detects cardiac fibrillat...[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]
Engineers who are new to wireless design and wireless product development need to master the basics of
RF measurement

Preface
In the analog era, due to the unchanged specifications and relatively simple device connections, as well as users' low requirements for image quality, the relatively simple environment...[Details]
introduction
In engineering practice, ultrasonic waves are often used to measure distances because of their strong directivity, slow energy consumption, and long propagation distance in th...[Details]
Fetal monitoring is an important means to ensure the safety of perinatal mothers and fetuses and achieve eugenics. Intelligent fetal monitoring is a monitoring method that analyzes the health stat...[Details]
1. What is fading?
In terms of scope, fading can be roughly divided into three types: large area fading, small area fading and indoor fading. As shown in Figure 1, large area fading refers t...[Details]
