Latest Patents

One of his latest patents is titled "System and method for providing the amplitude and phase delay of a sinusoidal signal." This invention discloses a system that provides an amplitude value and a phase delay value related to a sinusoidal signal to be measured. The method involves collecting phase values of a reference signal, which indicate when the signal to be measured exceeds or falls below the reference signal. These values are transmitted to a computation unit, which determines the amplitude and delay values. The system is designed to be cost-effective, particularly through the use of ASIC or FPGA circuits.

Another notable patent is "Electrical measurement circuit, gas detector and method for measuring a gas concentration." This invention features an electrical measurement circuit that includes an electrical reaction leg for forming an oscillator from a resonator. It also possesses a measurement leg supplied by the electrical reaction leg. The measurement leg contains an adjustable phase shifter, allowing for the adjustment of an additional excitation force applied to the resonator in phase quadrature with respect to the excitation force in the electrical reaction leg. This circuit is particularly suitable for creating a photoacoustic gas detector.
