Abstract

The COVID-19 pandemic has highlighted the need for a means of enforcing a spatial distance between individuals, of 1 meter or more (depending on the health policy of each country). Despite some urgent initiatives, nothing has really been conclusive. Currently, some devices have been implemented but using technologies that threaten individual freedom, are complex to implement and expensive (fixed camera or mobile robots with artificial intelligence). Thus, the objective is to design a rapidly functional prototype free of these problems. This article proposes a spatial distancing equipment using sensors (transmitter / receiver) with ultrasounds already existing in the trade, thus respecting the regulation in force on the acoustic emissions. The use of 4 sensors, connected to an Arduino microcontroller, allows to cover an area around the person of 360 degrees. When one of the sensors emits an acoustic wave, only the other 3 listen, avoiding the effects of reverberations. So, if one of the 3 perceives a wave, it means that another similar device is emitting in a radius too close and therefore that the recommended distance is not respected. The user will be warned by a sound or light signal. The prototype designed was quickly functional, adaptable for distances ranging from 20cm to 4m depending on the desired distance, and inexpensive. On the other hand, it is for the moment rather bulky but in the case of a marketing is quite possible to miniaturize it. [ABSTRACT FROM AUTHOR]

Abstract

A new ultrawide-band (UWB) antenna named the 'scissors antenna' has been designed specially for transient ultra-wide-band applications. The scissors antenna, which is composed of conducting wires, radiates ultrashort pulses with very low dispersion. The radiation of this antenna has been characterized by a transient measurement method suitable for characterizing UWB antennas with very low dispersion. After a presentation of the scissors antenna, this measurement method is described. The last part of the paper presents a comparison between the radiation characteristics of the scissors antenna obtained by the transient measurements and those obtained by the classical harmonic measurements. Index Terms--Transient measurements, ultrawide-band (UWB) antenna.

Abstract

Appeared since less than a decade, the Asian hornet invaded the Western Europe and has a direct impact on biodiversity as it contributes to the colony collapse disorder. The approach presented consists in a system of eradication based on their thermal weakness. As chemical pesticides and insecticides are prohibited in Europe, the method presented here, using electromagnetic microwave radiation is original and orientated to be environmental friendly and in favor of sustainable development.
