A sleep monitoring system () for monitoring the sleep of a pair of subject comprises a pair of CO2 sensors (') for mounting in different sleeping regions within a space () and a processor () communicatively coupled to the pair of CO2 sensors. The processor is adapted to, for each CO2 sensor in a particular sleeping region, monitor () 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 () the monitored CO2 concentration upon detecting () said presence; to determine () a degree of crosstalk between said CO2 sensors upon detecting said presence; and to derive () 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.

Sleep monitoring

Disclosed is an air purification system () including an air purification apparatus () comprising an air inlet (); an air outlet () for expelling air in a target direction () into a region and including an adjustment mechanism () arranged to adjust said target direction in response to a target direction adjustment signal from a control system for aiming the air outlet at the face of a person in said region; at least one pollutant removal structure () in between the air inlet and the air outlet; and an air displacement apparatus () for displacing air from the air inlet to the air outlet through the at least one pollutant removal structure, and a sensor () adapted to determine a breathing parameter of the person, wherein the air purification apparatus is configured to expel said air as a function of said breathing parameter. A computer program product for configuring such a control system is also disclosed.

A micro fluidics system includes a closed, expandable volume for mixing a fluid, and a flexible membrane for allowing mixing in the closed, expandable volume. The system further includes a surface having at least one channel for fluidically coupling a first side of the surface to the closed, expandable volume on a second side of the surface. The channel includes a first channel opening fluidically coupling the first side of the surface to the channel and a second channel opening fluidically coupling the channel to the closed, expandable volume. The expandable volume is defined by the flexible membrane closing the second channel opening when there is no fluid in the expandable volume.
