ULTRASOUND PATCH CAN MEASURE BLOOD PRESSURE DEEP INSIDE BODY

Scientists at the University of California San Diego created a new wearable ultrasound patch that non-invasively monitors blood pressure in arteries deep beneath the skin such as the jugular vein and carotid artery. The new patch could be helpful in detecting cardiovascular problems earlier on and with greater precision. In a proof-of-concept study, the patch performed as well as some invasive means to meas ...

Tv remote controlled home automation system

Tv remote controlled home automation system using pic microcontroller. With the help of a TV remote, we would be able to control different loads. Each button on the remote will have different functionality i.e. will turn ON/OFF different loads .TV remote will send a unique/different IR signal on each button press. TSOP (IR Receiver) will catch the signal and output a binary waveform (unique for each button) ...

BUK9J0R9-40H – A Super Junction MOSFET with Low On-State Resistance

A MOSFET known as a metal-oxide-semiconductor-field-effect transistor is a special type of field-effect transistor which has an insulated gate where in this case the voltage determines the conductivity of the device. Just like conventional transistors, they are also used for switching and amplifying signals. MOSFETs are now more commonly used in digital and analog circuits than BJTs (bipolar junction transi ...

Howto generate color video signals in software – Introduction

This document describes how to generate composite color video signals in software using an SX microcontroller. First the document describes the video signal and after that how to do it in software. There is also a zippped PDF-version (1.54MB) of this document, that is better if you wnat to print it to paper. (Note: The PDF-file also contains the games pong and tetris with source, so you might not want to pr ...

How to generate video signals in software using PIC

Background During the Christmas holidays 1997-1998, I started on a small project, trying to generate a video signal with a PIC16C84. I had seen some video clock generating video signals in software, and thought it was a quite interesting idea, and wanted to take it a step further. I didn't know much about video signals back then, I basically just had seen how a single scan-line works. But during the spring ...
