Abstract: A method for determining a personalized anti-snoring solution for a patient includes performing an analysis of a sleep period of the patient in which snoring by the patient is occurring; advising the patient of an anti-snoring solution based on information obtained in the analysis; tracking a further sleep period of the patient in which the patient is employing the anti-snoring solution; and advising the patient of changes to the anti-snoring solution based on a comparison of information obtained in the tracking with data obtained in the analysis.

Abstract: An optical particle sensor has at least first and second threshold settings applied to an optical sensor or a sensor signal to obtain first and second optical sensor readings. The first and second optical sensor readings are processed to determine a parameter which is dependent on a type of pollution event. The parameter is used to determine from at least one of the first and second optical sensor readings a mass of all particles below a first particle size. In this way the mass of all particles below a desired size can be evaluated, even though the optical sensor may not be responsive to the smallest particles.

Abstract: A sensor system is provided for measuring particle concentration and mass concentration in an aerosol. An optical sensor (33) is used for measuring a particle concentration and a mechanical sensor (32) is used for measuring a mass of collected particles. A particle concentration in the aerosol is monitored using the optical sensor (33), until detection of a particle generating event. Upon detection of a particle generating event, a mass measurement using the mechanical sensor (32) is performed and the mass measurement is used to calibrate the optical sensor (33). This approach enables the lifetime of the mechanical sensor to be extended, because it is only used when events are detected. The optical sensor, which typically is less accurate for mass sensing, is calibrated by the mechanical sensor.
