Latest Patents

One of his latest patents is a "Pacemaker with switchable circuits and method of operation of same." This invention involves a cardiac pacemaker or other implantable biomedical device that contains one or more switchable circuits. A control system, preferably incorporating a microprocessor, manages predetermined changes in the operating characteristics of these circuits. In a cardiac pacer embodiment, the input amplifier circuit can be switched to have different characteristics, such as filter settings and sensitivity, during specific portions of the pacer cycle. Additionally, the operation of a circuit can be monitored over multiple operating cycles, allowing for controlled switching of circuit characteristics based on cumulative monitored performance. A specific example of this invention includes changing characteristics of a filter circuit used in a pacer, which adjusts the pacer rate according to the determined stimulus-T wave time interval.

Another significant patent is the "CMOS Circuits with parameter adapted voltage regulator." This invention features a self-adjusting voltage regulator circuit on a CMOS chip, designed for use with both digital and analog circuits. It provides a voltage selected according to the chip's characteristics to optimally control the current operation of CMOS circuits. The voltage regulator circuit includes a reference CMOS pair with a predetermined geometry, and current means are provided to drive a current through the reference pair, adjusted to operate at a desired point of current-controlled operation. The voltage across the reference pair is utilized to provide the regulated voltage to other CMOS pairs, ensuring current-controlled operation based on their respective geometries.
