WORK HISTORY
Lead Asic and System Principal Engineer - R & d @Neuspera Medical Inc
San Jose, CA, US
Key Company Wide Achievements: • Found a technological root cause and conceived a solution to a major problem of a system control that caused significant reduction of system performance for some patients and resulted in temporarily halting the second IDE trial. Trial resumed after I addressed the root cause as solution was verified.• Identified and solved poor wireless transmitter battery charging circuit and fixed optimized the charging scheme. Significantly reduced battery charging field RMA cases.• Synthesized a novel ‘sacral phantom liquid’ for wireless and implant in a tank for performance characterization. Phantom mimics bodily dielectric properties of the sacral environment at 900 MHz energy transfer band, and also at the much lower stimulation frequency spectrum where the phantom impedance mimics the ~ 1 kOhm human figure.• Defined and extensively studied key maximum stimulation distance system variables such as radial, axial angles, offset, of the implant relative to its wireless transmitter energy source, impact of electrode array curvature and clocking relative to the implant’s antenna. Performed detailed specialized implant ASIC characterization of energy consumption and its impact on stimulation distance variation. All of these findings were confirmed by an independent technical audit firm.
