Latest Patents

One of Gaboury's latest patents is an illuminant discriminator that provides detection of high efficiency. This innovative device distinguishes a range of separate illuminants by modifying the frequency response of a signal output from a photodetector. The system employs a switchable high pass filter coupled to the photodetector, which has two filter sections. The first section is designed to pass signal components from various types of lighting, while the second section separates out the high efficiency components. The output is processed by a log amplifier to develop flicker frequency harmonics, allowing for the identification of the source illuminant through comparator stages. This technology effectively addresses the challenges posed by undersampling artifacts in mixed illuminant spectra.

Another significant patent is a photodiode amplifier circuit with improved sensitivity to high efficiency lighting. This amplifier features an input stage with a differential pair of transistors, which provides low input impedance. The design allows the photodiode to achieve a lower time constant, extending the system response into higher frequencies. This photodiode amplifier is particularly useful in illuminant discrimination applications.
