Latest Patents
One of Kuanfu Chen's latest patents is titled "Electrical charge balancing method and apparatus for functional stimulation using precision pulse width compensation." This invention presents an apparatus and method for electrical charge balancing during functional neural stimulation. It generates a stimulus pulse, either cathodic or anodic, and subsequently produces a charge compensating pulse of opposite polarity after a selected delay. The electrode circuit examines electrode voltage after the stimulus pulse terminates, using this voltage to determine the duration for extending the width of the charge compensating pulse. This method ensures accurate electrical charge cancellation, effectively removing residual charges from the electrode by precisely controlling the pulse width.
Another notable patent is the "Circuit architecture for high channel count high-voltage neural stimulator." This invention provides an external circuit that communicates power and data to a neural stimulator implant circuit. It allows data from external devices, such as image data from a camera in an epiretinal application, to be communicated to the implant. Multiple pixel circuits within each implant demultiplex the digital signals, outputting separate nerve stimulator outputs configured for connection to nerves. In some configurations, the implant circuits can be clustered in a master-slave arrangement to increase the number of available neural stimulation outputs.
