Abstract

A rain and fog testing apparatus, comprising a fluid channel that runs between a first fluid shutoff coupler and a second fluid shutoff coupler and has at least one dispersion head fluidly coupled to the fluid channel. A liquid pump can be fluidly coupled to the fluid channel at an output end. A liquid heater may also be fluidly coupled to the system along with a controller that provides electrical control of the first fluid shutoff coupler, the second fluid shutoff coupler, the dispersion head, the liquid pump, and the heater. Further, the second fluid shutoff coupler is capable of fluidly coupling a first fluid channel to a plurality of fluid channels and the controller can adjust the orientation of the first fluid shutoff coupler, the second fluid shutoff coupler, the dispersion head, the liquid pump, and the liquid heater to create a simulation of a plurality of rain or fog events.

First claim

The invention claimed is:

1. A method of controlling a rain or fog testing apparatus and corresponding device under test, comprising:
placing a rain or fog testing apparatus on a body of water;
placing a transmitter at one end of the rain or fog testing apparatus, the transmitter oriented to transmit a signal through a rain or fog event generated by the rain or fog testing apparatus;
placing a receiver at a second end of the rain or fog testing apparatus, the receiver oriented to receive the signal transmitted through the rain or fog event;
receiving user inputs by a controller, where the user inputs determine a type of rain or fog event and when to transmit and receive the signal;
implementing the rain or fog event determined by the user inputs by engaging a series of valves and a series of pumps to create the corresponding rain or fog event;
initiating the transmitter to send the signal through the rain or fog event and receiving the signal with the receiver;
recording the signal sent by the transmitter and received by the receiver during the rain or fog event; and
disengaging the series of valves and the series of pumps to allow the rain or fog testing apparatus to become submerged under the body of water.
