Epilepsy affects approximately 1% of the world population. Antiepileptic drugs are ineffective in approximately 30% of patients and have side effects. We are developing a noninvasive, or minimally invasive, transcranial focal electrical stimulation system through our novel tripolar concentric ring electrodes to control seizures. In this study, we demonstrate feasibility of an automatic seizure control...
Epilepsy affects approximately one percent of the world population. Antiepileptic drugs are ineffective in approximately 30% of patients and have side effects. We are developing a noninvasive, or minimally invasive, transcranial focal electrical stimulation (TFS) system through our novel concentric ring electrodes to control seizures. Here we report on the development of a seizure detecting algorithm...
In order to research spark discharge, including the energy, electromagnetic radiation characteristics and its influence on surroundings, a spark discharge experiment was set up, voltage waveforms were recorded by an oscillograph and discharge energy was calculated when discharging. Physical models were founded using FEKO and different electromagnetic radiation patterns were simulated under a range...
We have reported a method to achieve small half-wave voltage for high-speed MMI-MZI GaAs/GaAlAs electro-optic modulators and switches with co-planar electrodes for polarization-insensitive operation. By biasing the devices at the reverse breakdown region, the voltage to achieve switching can be greatly reduced about 23 V to 3 V. Such a small half-wave voltage would be very important for high-speed...
