Sleep apnea is a very common sleep breathing disease. According to research, about 24% of adult men and 9% of adult women, or more than 2 million people, suffer from this disease ...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
As the price of readers and tags decreases and the global market expands, the application of radio frequency identification (RFID) is increasing day by day. Tags can be powered by readers (passive ...[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]
Lithium-ion batteries have a high energy-to-weight and energy-to-volume ratio, no memory effect, can be recharged many times, have a long service life, and are becoming increasingly cheaper. A good...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[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]
Billboards are information display terminals for the public, with a wide range of civil and commercial values. However, most of the information displayed on billboards is currently solidified in th...[Details]
Focus shift problem
Visible light and infrared light have different wavelengths, so the imaging focus is not on the same plane, which results in a clear image under visible light condition...[Details]
After being widely adopted in applications such as backlighting of portable products with small and medium-sized screens, light-emitting diodes (LEDs) have entered the field of general lighting in ...[Details]
"Where am I? Where am I going? Where is he/she? How far is he/she from me?..." Do you often have such questions like me? In fact, who can deny that these are questions that we often think about, ev...[Details]
