Programmable active pixel sensor to investigate neural interactions within the retina [PDF]
, 2009 Detection of the visual scene by the eye and the resultant neural interactions of the retina-brain system give us our perception of sight. We have developed an Active Pixel Sensor (APS) to be used as a tool for both furthering understanding of these ...

How should we assess the mechanical properties of lower-limb prosthesis technology used in elite sport?: An initial investigation [PDF]
, 2013 Despite recent controversy, it is not yet formally recognised how lower-limb prosthesis should be assessed for their performance. To assist in this process, experiments are undertaken to investigate the linearity, stiffness and assessment of feet based ...
