Abstract: A method for calculating an augmented health risk score by a health risk system including a processor, including: receiving, by the processor, CO2 level data and location data for a user; receiving, by the processor, location data for the user; determining, by the processor, when the user is outdoors based upon the received CO2 level data and calculating an outdoor pollution exposure based upon pollution data for the user's location; determining, by the processor, when the user is indoors based upon the received CO2 level data, calculating a ventilation rate based upon the received CO2 level data and the local outdoor pollution levels, and calculating an indoor pollution exposure based upon pollution data for the user's location; and calculating, by the processor, the augmented health risk score based upon the outdoor pollution exposure, indoor pollution exposure, a medical history of the user, and demographic information of the user.

Abstract: The invention relates to a system and a method for providing an exacerbation risk score for a respiratory disease of a patient. The system measures a heart signal and/or a blood circulation signal of a patient and detects cough events and sneeze events in the measurement data. The cough events and sneeze events are indicative for an onset of a contagion and/or an allergy, which can rapidly exacerbate a respiratory disease of the patient. Thus, the system is configured for providing unobtrusively an exacerbation risk score to the patient and/or to a physician.

Abstract: Disclosed is an air purification system (10) comprising an air purifier apparatus (50) for removing a pollutant from air, a sensor (21, 23) for sensing a concentration of the air pollutant and a scent release apparatus (40) responsive to a scent release signal, wherein the air purification system further comprises a processor (31) adapted to monitor the pollutant concentration from sensor data received from the sensor and to generate the scent release signal upon the monitored pollutant concentration falling below a defined threshold. Also disclosed is a method of generating a scented atmosphere in a room housing an air purification apparatus (50) for removing a pollutant from the air in the room.

Abstract: A sleep monitoring system (10) for monitoring the sleep of a subject is disclosed. The system comprises a CO2 sensor (21) and a processor (31) communicatively coupled to the CO2 sensor, wherein the processor is adapted to monitor a CO2 concentration from sensor data produced by the CO2 sensor; and derive sleep pattern information from the monitored CO2 concentration, wherein the sleep pattern information comprises at least an indication that the subject is awake and an indication that the subject is asleep. A sleep monitoring method and computer program product are also disclosed.
