Latest Patents

One of Nelson's latest patents involves a **Magnetic Field Sensor**. This implantable medical device utilizes a solid-state sensor to detect the presence of an external magnetic field. The design incorporates first and second split-drain field-effect transistors (MAGFETs), which are cross-coupled in such a manner that an external magnetic field, aligned perpendicularly to the channel regions of the MAGFETs, results in an increase in current through one half of each MAGFET, while the other half experiences a decrease in current. Additionally, a high-gain differential amplifier is connected between the MAGFETs to detect variations in the current flowing through the respective split-drain halves, producing an output voltage responsive to the external magnetic field's application. This sensor is particularly efficient, operating at low power supply voltages and bias currents, making it ideal for integration into implantable medical devices like cardiac pacemakers.

Another significant innovation by Nelson is a **Low Cost Implantable Medical Device** designed to function under limited conditions. This device operates with synchronous circuits powered by an ultra-slow master clock signal, eliminating the need for a crystal oscillator. It can be programmed non-invasively with an externally applied programming magnet, which is detected by a solid-state magnetic sensor (MAGFET) circuit embedded in the device. The MAGFET circuit can differentiate between two polarity orientations of the programming magnet, allowing for the increase or decrease of programmable parameters based on the polarity detected. Furthermore, the device performs a threshold margin test upon initial placement, administering three asynchronous stimulating pulses to ascertain the current pulse width and amplitude settings.
