Fishing Position Detection by Wearable Sensing to Achieve Fishery Support

HeadRacer: A Head Mounted Wearable Computer with Ultrasonic Position Sensing∗

This demonstration is in three parts. Firstly we are showing a wearable computer built into a cycle helmet. This comprises a gumstix single board computer, an ultrasonic receiver module and a lithium polymer battery. The helmet interacts with an ultrasonic positioning system. This system requires no RF or infra-red synchronisation enabling fast and accurate performance. Lastly we are providing ...

Wearable pupil position detection system utilizing dye-sensitized photovoltaic devices

Detection of the line-of-sight (LOS) has a variety of applications, such as communication tools for elderly or disabled people, assisting drivers, nd effective location of traffic signs. To realize such promising applications, there is strong demand for an LOS detection system that does not estrict users’ activities and inflicts no mental stress. The LOS can be obtained by combining the directi...

A Sustainable Fishing Plan for the Farne Deeps Nephrops fishery

Compressed Sensing via Iterative Support Detection

We present a new compressive sensing reconstruction method ISD, aiming to achieve fast reconstruction and a reduced requirement on the number of measurements compared to the classical l1 minimization approach. ISD addresses failed cases of l1–based construction due to insufficient measurements, in which the returned signals are not equal or even close to the true signals. ISD will learn from su...

Disturbance of the Marine Benthic Habitat by Commercial Fishing: Impacts at the Scale of the Fishery

Commercial fishing is one of the most important human impacts on the marine benthic environment. One such impact is through disturbance to benthic habitats as fishing gear (trawls and dredges) are dragged across the seafloor. While the direct effects of such an impact on benthic communities appear obvious, the magnitude of the effects has been very difficult to evaluate. Experimental fishing-di...
