Abstract: This paper considers a full-duplex relay-assisted system for covert communication, in which both the transmitter and the relay are the sender of covert messages. Different from current works ...

The RADIX2HD uses the Relay2 functionality to power on/off the voltage regulator for the video transmitter. This was working correctly in 4.4 but no longer works as expected in 4.5. By default, when ...

We are fascinated when we see machines work together, seemingly with minds of their own. The TV show “How It’s Made” became popular for simply showing how products are made in an automated factory ...

Fig. 1: Add this relay to prevent shorted transistors in the MW-1. Usually after a transmitter is discontinued, any hope of upgrades or improvements fades. Some enterprising engineers can’t help but ...

Members can download this article in PDF format. In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to ...

Emerson announced the release of the Rosemount 4051S Pressure Transmitter, a new industrial measurement solution with the ...

[Mr. Carlson] bought a Globe Scout Model 40A ham radio transmitter at a hamfest. The 40A was a grand old transmitter full of tubes, high voltage, and a giant transformer. It is really interesting to ...

Structural sensors are moving into the Information Age. Phase IV Engineering has introduced a new line of small, strain gauge sensor modules that use breakthrough technology—including the Internet of ...
