Latest Patents

One of her latest patents is a high temperature voltage regulator circuit. This invention includes a high voltage shunt regulator circuit that features a high voltage device with a predetermined reverse-conduction threshold. It is connected in series with a thermal compensation device comprising a plurality of gate threshold amplifiers. The high voltage device consists of a series of zener diodes, which provide high voltage regulation up to at least about 1600V. The thermal compensation device exhibits a negative temperature coefficient that offsets the positive temperature coefficient of the zener diodes, allowing efficient operation at temperatures as high as about 200°C.

Another notable patent is a logging tool for cement evaluation. This invention combines a gamma-ray tool and an acoustic logging instrument within an elongated housing. It includes a transmitter for sound and sound sensors located at predetermined distances above the transmitter. The design incorporates a lead-bonded steel tube that acts as a sound isolator bar, enhancing the tool's effectiveness in evaluating cement.
