A process is proposed for recovering disturbed digital signals, wherein the electrical signals pass through a feedback equalizer and an analogue control of the setting parameters of the equalizers is performed. The polysilicon gate electrode and the polysilicon gate pad have a larger width than the polysilicon gate line. The data is recreated using automated contextual delivery methods and processes. If the reflected sample spectrum contains the wavelengths of the absorption spectrum of the filter, the sample did not absorb the wavelengths and does not contain the substance. This can facilitate processing of numerous data elements, simplifying processing andor display requirements to achieve a given selection based on user criteria. The treatment device includes a neck bridge having a delivery configuration and a deployed configuration.
