This paper presents the design of a multichannel stimulator ASIC for an implantable neural prosthesis to restore 3-D vestibular sensation. The stimulator can provide the three semicircular canals with biphasic current pulses at rates between 1 and 500 pps with current amplitudes up to 1 mA. The ASIC was implemented in 0.6 μm HV CMOS technology and post-layout simulations are presented.
The aim of this paper is to compare three recording methods for interference rejection from tripolar nerve cuffs by testing in a saline-filled tank. The three methods were: the quasi-tripole (QT), the modified-quasi-tripole (mQT) and adjusted true tripole (aTT). When the interfering electric field that surrounds the cuff is solonoidal and coaxial with the cuff, the mQT allows the interference that...
A novel, patented, mechanical rowing force sensor has been simulated, constructed and tested. The sensor was set in a modified oarlock together with electronic processing including a Bluetooth transmitter. A Bluetooth-enabled mobile telephone/ laptop with a Graphical User Interface written in Java was used to display the 2-dimensional force on an oar vs. time. The visual display to a coach of rowing...
