Abstract: The invention is a method of automatically adjusting an electrode array to the neural characteristics of an individual subject. The response to electrical neural stimulation varies from subject to subject. Measure of impedance may be used to predict the electrode height from the neural tissue and, thereby, predict the threshold of perception. Alternatively, electrode height may be measured directly to predict the threshold of perception. Also, impedance measurement may be used to quickly identify defective electrodes and proper electrode placement.

Abstract: A method for efficiently determining whether a distributorless or hybrid ignition system is the origin of engine problems by consecutively disconnecting and reconnecting the primary connector from each coil of the ignition system. Once a single primary connector is disconnected from a coil and engine misfiring or roughness declines, the problem cylinder pair has been located. The method further includes measuring the firing line voltage of accessible spark plug wires for each cylinder to identify a single faulty cylinder, that may now be serviced.

Abstract: An improved device is described for measuring and registering lumbar spinal movement. The device, which is portable, is attached at an upper and lower portion of the lumbar region and measures multiple axis of motion by means of independent electric sensors. The device of the invention is an improvement over prior art devices because it provides appropriate compensation for errors induced through interaction of three axis only of rotational movement.
