Latest Patents

One of Rui Protasio's latest patents is a method and apparatus for detecting a gas concentration with reduced pressure dependency. This invention relates to a method that makes the measurement of a trace gas concentration invariant or at least less affected by pressure variations in the gas and atmospheric pressure changes. The method neither requires a pressure sensor nor a pressure calibration routine. Furthermore, it can be applied to other gas species present in the background gas or to the background gas itself that cross-interfere with the target gas of interest. This allows for the removal of any pressure dependency of cross-interference parameters of other gas species and/or the background gas. The new method for accurately measuring a gas concentration is based on optimizing the wavelength modulation amplitude of the laser to minimize pressure dependency.

Another significant patent by Rui Protasio is related to a laser diode structure with an integrated temperature-controlled beam shaping element for gas detection. This invention features a hermetically sealed housing with electrical connections, a laser diode chip, and a temperature control system. A thermo element in the form of a Peltier element forms the temperature control system, ensuring optimal performance. The beam shaping element acts on a laser beam emerging from the laser aperture of the laser diode chip before it passes through the window, enhancing the accuracy of gas detection.
