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.

Abstract: The invention provides a monitoring device for monitoring an air cleaning system for determining when a particle filter of the air cleaning system needs cleaning or replacement. The monitoring device is a remote unit for application to the air cleaning system when a periodic monitoring function is to be performed. It is used to monitor changes in the sound made by the air cleaning system over time to derive information relating to the filter status.

Abstract: A sleep monitoring system (10) for monitoring the sleep of a pair of subject comprises a pair of CO2 sensors (21,21′) for mounting in different sleeping regions within a space (1) and a processor (31) communicatively coupled to the pair of CO2 sensors. The processor is adapted to, for each CO2 sensor in a particular sleeping region, monitor (203) a CO2 concentration from sensor data produced by the CO2 sensor in said particular sleeping region to detect a presence of a subject in said sleeping region; to register (207) the monitored CO2 concentration upon detecting (205) said presence; to determine (303) a degree of crosstalk between said CO2 sensors upon detecting said presence; and to derive (305, 313) sleep pattern information for said subject from the registered CO2 concentration during said presence as a function of the determined degree of crosstalk, wherein the sleep pattern information comprises at least an indication that the subject is awake and an indication that the subject is asleep.

Abstract: An air purifier (10) uses an air purifier filter unit (12) and a sensor (26) for sensing the matter to be filtered by the air purifier filter unit. By monitoring (18) the performance of the air purifier combined with information about the air purifier filter unit, it is possible to determine a volume of the space in which the air purifier (10) is deployed.
