Abstract: A communication system includes a first communication gateway arranged proximate to a surface of a body of water and an underwater communication gateway. The underwater communication gateway is configured to receive data from a first underwater communication device using radio frequencies and the ethernet data link layer protocol, to convert the data received from the first underwater communication device from the ethernet data link layer protocol to the second data link layer protocol, and to transmit, using optical radiation and the second data link layer protocol, the data converted by the underwater communication gateway to the first communication gateway. The first communication gateway is configured to convert the data transmitted by the underwater communication gateway from the second data link layer protocol to the ethernet data link layer protocol, and to transmit, using the ethernet data link layer protocol, the data converted by the first communication device to a further communication device.

Abstract: An aerosol detection system for detecting airborne organic matter, the detection system including a corridor extending along a longitudinal axis and having first and second ends; an access gate connected to the first end of the corridor and configured to control access of an individual to the corridor; a person detection system located in the corridor and configured to determine the presence of the individual inside the corridor; and a testing set configured to generate an air puff, which directs an exhaled breath of the individual for determining a presence of the airborne organic matter. The corridor has a width wc that allows movement of a single individual past the testing set.
