20090133313 | Angle-Based Filling Ratio Indicator - The invention relates to a filling ratio indicator for a trawl, Danish seine or a similar towable seine device with a net, comprising a main body arranged to be located on the surface of the net and with attachment devices for attachment to the net. The invention is characterised in that it comprises at least one angle sensor for measuring the angular position of the main body and thereby the angular position of an area of the net in the immediate vicinity of the sensor and a processing unit for providing, based on the said measurement, an indication of the filling ratio of the trawl, Danish seine or seine device. The invention also relates to a method and a system for providing an indication of the filling ratio of a seine device. | 05-28-2009 |
20120002507 | METHOD FOR DETERMINING DIFFERENCE IN DISTANCE - The invention consists of a method which comprises a plurality of steps for determining difference in distance from a reference point to at least two sensor modules | 01-05-2012 |

20150103631 | TRAWL HEIGHT INDICATOR - A trawl sensor device for monitoring trawl doors and the distance of the trawl to the boom during trawling operations comprises at least one acoustic transmitter and receiver, the transmitter being adapted to be positioned such that an acoustic signal is transmitted towards the seabed at a forward-pointing angle, and means for communication between the sensor device and a vessel. The transmitted acoustic signal is reflected from the seabed and is received at this position and the distance between the acoustic transmitter and the seabed is calculated based on the difference in time between transmission and reception of the acoustic signal and the forward-pointing angle. | 04-16-2015 |
