Acoustic transmissions were generated in aluminium and Carbon Fibre Composite (CFC) panels. The FBG receiver was coupled to the bottom surface opposite a piezoelectric transmitter. For the CFC, a second FBG was embedded within the layup for comparison. We show the transfer function, frequency response, and transient response of the acoustic communications channels. In addition, the FBG receiver was used to detect Phase Shift Keying (PSK) communications signals, which was shown to be the most robust method in a highly resonant communications channel. http://www.mdpi.com/1424-8220/11/1/455/ Tue, 04 Jan 2011 00:00:00 CET Sensors 2011-01-04 11 1 Article 455 471 1424-8220 A Fibre Bragg Grating Sensor as a Receiver for Acoustic Communications Signals 2011-01-04 doi: 10.3390/s110100455 Graham Wild Steven Hinckley http://www.mdpi.com/1424-8220/10/12/10663/ An experimental investigation was undertaken to ascertain the potential of using Helmholtz resonance for volume determination and the factors that may influence accuracy. The uses for a rapid non-interference volume measurement system range from agricultural produce and mineral sampling through to liquid fill measurements. By weighing the sample the density can also measured indirectly. http://www.mdpi.com/1424-8220/10/12/10663/ Tue, 30 Nov 2010 00:00:00 CET Sensors 2010-11-30 10 12 Article 10663 10672 1424-8220 The Use of Helmholtz Resonance for Measuring the Volume of Liquids and Solids 2010-11-30 doi: 10.3390/s101210663 Emile S.
