An implantable device can predict the onset of epileptic seizures using adaptive feature extraction filters. Binary decisions (act / don’t act) are then used to deliver therapy and terminate epileptic episodes prior to generalization. Similar methodologies are used to detect dynamic and clinical event onset.
Interventional Cardiology diagnoses and responds to the build up of plaque in coronary arteries. When intravascular ultrasound phase and amplitude are used, real-time feature extraction filters allow for automatic tissue identification. Similar to the neuroprosthesis application, a diagnostic tool can be converted to a therapeutic device by using real-time features to close the loop.
CLOSED-LOOP CONTROL SYSTEMS AND AUTOMATION
Whether you are controlling a lung aspirator, thermodynamic parameters, fluid flow, or a robotic prosthesis, control loops need to be stable, responsive and connected to the right signal sources. The example below shows EMG electrodes on five muscles that manipulate a single d.o.f. on a normal hand. A metacarpophalangeal (MP) joint depends on many sources that turn on and off.
Like any robotic problem, inverse kinematic and dynamic equations from the signal sources are required. The use of feature extraction, context data (orientation with respect to gravity) allows for predictable control and device training of the joint.
