The Virtual Assistive Surgical Trainer (VAST) is an approach developed to train surgeons in minimally invasive procedures. It uses surgical instruments augmented with micro-sensors, and knowledge-based inference techniques to provide objective, data-driven feedback and performance assessment for complex exercises. The assessment is typically based on the expertise of senior surgeons and, thus, a single...
Today, the capability of the human olfactory system is still, in many ways, superior to that of the electronic nose. Although electronic noses are often compared with their biological counterpart, they neither mimic its neural architecture nor achieve its discriminating performance. Experimental studies on the mammalian olfactory system suggest that the nasal cavity, comprising of the mucous layer...
Today, the capability of the human olfactory system is still, in many ways, superior to that of artificial detection or the so- called electronic nose. Although electronic noses are often compared to their biological counterpart, they neither mimic its complex neural architecture nor achieve its performance in discriminating between complex odours. Recent developments in our understanding of the human...
Here we describe the component subsystems which comprise the first silicon-based olfactory system, each implemented in analog VLSI/MEMS. These include a biologically constrained neuronal model, chemical micro-sensor array and associated interface circuitry. We present a spiking olfactory bulb model, a reduced 70 element broadly-tuned chemosensor array (25 different chemsensor tunings), alongside details...
A programmable analog sensor interface integrated with an array of heterogeneous chemical FET/resistive sensors is presented. The sensory interface primarily addresses the problem of loss of measurement range due to large variations in baseline signals among sensors in the array. A circuit is proposed to cancel the baseline signals in the sensor array leading to improved measurement resolution. An...
