Patent number: 10140427Abstract: The analysis of compounds utilising the physical response of cellular networks is described. Typically, the electrical characteristics of the cellular network are monitored although other characteristics such as fluorescence may be monitored. In any event, the analysis utilises signal processing techniques to derive a set of features which may be evaluated against a library of known responses. The technique may be applied to both the detection and identification of unknown compounds and the detection of concentrations of known compounds.Type: GrantFiled: March 23, 2004Date of Patent: November 27, 2018Assignee: Midas Mediscience LimitedInventors: Richard D. A. Heal, Alan T. Parsons

Patent number: 7457197Abstract: Low frequency vibration induced noise is reduced in a towed sonar array of the type comprising a number of oil-filled modules joined end to end with each module housing a plurality of hydrophones by arranging that the signal output from each hydrophone in an array is equally weighted at low frequencies to form a single channel. Beamforming is then carried out by applying different weights to the different module channels.
