Latest Patents
One of his latest patents is a "Telephone with a demodulator circuit with an improved local oscillator." This invention addresses the challenges posed by aging and drift of a local oscillator in mobile telephones. By shifting the frequency of the local oscillator upwards, Dugast ensures that base station logging-on signals are accurately measured, regardless of whether the drift is upwards or downwards. This innovation allows for better compliance with standards without requiring an oscillator with guaranteed frequency stability over time.
Another significant patent is the "Method of receiving voice signals by a mobile telephone." This method aims to conserve energy and extend the standby and talk time of mobile devices. By segmenting the activity of the mobile telephone, even during standby periods, the device only activates when the reception quality of surrounding signaling is adequate. This approach reduces energy consumption during communication, particularly when the other party is silent, by eliminating the processing of low-quality demodulated signals.
