Spatial Jobs Online News Bulletin
September 2014 Issue 61
Two watery articles in this news bulletin, one which is so important for this island continent of Australia.
We hear so much about drones, how useful they can be but on the flip side there is the discussion about invasion of privacy and possible misuse. And then there is the invention of two students from the University of Wollongong who have won an innovation award for using a quadcopter UAV to quickly deliver a floatation device to a distressed swimmer.
The UAV, designed by Nicolas Roach and Leo Stevens, uses magnets to carry a floatation device out to sea, releasing it via a remote switch operated by the lifesaver on-shore. This can buy crucial extra time before the manned rescue vessel can reach the swimmer.
“We custom built a housing which allowed the [rescue tube] to be fixed to the bottom of the drone and released on command using a radio signal,” said Mr Stevens. The two creators are hoping this state of the art drone will be dropping lifesaving floatation devices on Australian beaches this summer.
So to what is under the water. Four hydrographic surveyors at Sydney Ports keep an ever-vigilant eye on the bottom of the Harbour to make sure possible dangers in the depths do not disrupt water traffic on Port Jackson. We are looking for anything that can impact on shipping and shipping schedules,” Ms O’Connell said.
Among the items found was a brand new Toyota Landcruiser 4WD, 50 metres from the wharf at White Bay. “We still can’t figure out how it got that far out”. “It may have fallen off the back of a ship.” One would hope that is how it did end up out there!
