Latest Patents

One of Luiz's latest patents is titled "Method for harmonic number determination in a microwave frequency counter." This invention provides a method and apparatus for determining a generalized harmonic number in a harmonic heterodyne converter. The technique reduces the likelihood of error in determining the harmonic number by ensuring a large separation between local oscillator frequencies. The method involves estimating the harmonic number using closely spaced local oscillator frequencies and then computing widely spaced local oscillator frequencies for a corrected generalized harmonic number. Variations of this technique cater to both high and low harmonic numbers.

Another notable patent is the "Single sampler heterodyne method for wideband frequency measurement." In this invention, an input signal of unknown frequency is applied to a sampler driven by a sampling signal. The sampling frequency varies in response to a randomly or pseudo-randomly varying signal, which causes the intermediate signal to also vary. Correlation techniques are employed to determine the harmonic number and sideband, enabling the calculation of the input frequency. This method effectively reduces errors in determining the harmonic number and sideband due to frequency modulation of the input signal.
