Monitoring Patient’s remotely really important especially for patients suffering from long-term disease. Vital signs such as pulse rate, Body temperature etc., needs be monitored regularly they are primary ...

<p class="Abstract">The continuous monitoring of cement-based structures and infrastructures is fundamental to optimize their service life reduce maintenance costs. In the framework EnDurCrete project (GA no. 760639), a remote system based on electrical impedance measurements was developed. Electrical measured according Wenner’s method, using 4-electrode arrays embedded in concrete during...

I had been running an APRS RF-tointernet gateway (an iGate) for a few months using a sound-card modem by Thomas Sailer, HB9JNX/AE4WA, (soundmodem).1 The software modem caused various problems and I have not found a suitable replacement. Eventually, I decided to try to implement my own sound-card-based software modem. The results have been very good, in spite of the fact that I do not have much ...

We demonstrate the successful transmission of Data Over Cable Service Interface Specification (DOCSIS) signals in the 600 MHz and 5.5 GHz frequency bands. Both signals are generated simultaneously using an optical harmonic up-conversion of the DOCSIS signal provided by a cable modem termination system (CMTS). The optical signal is transmitted over 10 km SSMF. After photo-detection, the wireline...
