There is provided an apparatus () for detecting subjects with disordered breathing. The apparatus () comprises one or more processors () configured to acquire an acoustic signal from an acoustic sensor () in an environment, determine a plurality of acoustic signal components from the acquired acoustic signal and determine a plurality of signal envelopes or energy signals based on the acoustic signal components. One or more processors () are also configured to analyze the determined plurality of signal envelopes or energy signals to detect whether there are one or more subjects in the environment with disordered breathing.

A mandibular advancement device () includes a first brace member () structured to engage an upper dentition of a user, a second brace member () structured to engage a lower dentition of a user, and a number of coupling assemblies () each coupling the first brace member to the second brace member. Each of the number of coupling assemblies includes an actuating element () structured to automatically adjust a dimension () of the coupling assembly. The actuating element is selected from the group consisting of a biasing element () and a volume responsive material ().

A method of treating snoring among two users includes determining that snoring by at least one of the users is occurring, and responsive thereto, either: (a) determining that only one of the at least two users is snoring and responsive thereto generating a signal to produce an anti-snoring motion in an active pillow associated with the one user and generating another signal to produce a distracting motion in another active pillow associated with the other user; or (b) determining that both of the users are snoring and responsive thereto generating signals to produce anti-snoring motions in each of the active pillows.

An air purifier filter system comprises an air purifier filter unit and a machine readable identifier which provides information concerning the filter unit type and performance information specific to a target pollutant to be filtered by said air purifier filter unit from a plurality of different pollutants that can be filtered by that filter unit type. This information can be used to provide an end of life prediction for the filter unit or provide advice that the filter should be changed for other reasons. This enables the user to be given advance warning, and to be given instructions when it is time to change the filter unit. The instructions to change the filter unit may be more accurate than a simple timer as they can take account of the type of filter unit and the performance information. In some examples the use history of the filter unit may also be used to predict the time when it should be changed.

A method of characterizing a patient's disordered breathing during a sleeping period includes performing a first partial characterization of a time axis of an audio signal in order to learn the most prominent and highly relevant events. Only at a later stage, i.e., after sufficient observation of the highly relevant events, is a full segmentation of the entire time axis actually carried out. Linear prediction is used to create an excitation signal that is employed to provide better segmentation than would be possible using the original audio signal alone. Warped linear prediction or Laguerre linear prediction is employed to create an accurate spectral representation with flexibility in the details provided in different frequency ranges. A resonance probability function is generated to further characterize the signals in order to identify disordered breathing. An output includes a characterization in any of a variety of forms of identified disordered breathing.

A system determines a risk level of a respiratory attack of a user of the system. The system comprises part of a network of systems, and it reports information to, and receives information from, the network. The system comprises a local activity monitoring device for tracking the physical activity level of the user. Location information and activity levels in respect of other users of the network of systems are received, relating to when they have suffered a respiratory attack. A warning can then be given to the user which takes account of the location of the user and the activity level or planned activity level of the user, and the received location information and activity levels in respect of other users.

The present invention relates to a device, system and method for CO2 monitoring. To enable continuous monitoring at low cost and in a simple manner, the device comprises a signal input () for obtaining one or more monitoring signals () of a monitored area, a breathing monitor () for determining one or more breathing parameters () of one or more subjects present in the monitored area from the obtained one or more monitoring signals, and a CO2 estimation unit () for estimating the CO2 level () in the monitored area based on the determined one or more breathing parameters.

A mass sensor is provided for measuring a particle mass within an aerosol. The duration of a sensing cycle is set such that a pre-set change in mass resulting from particles deposited is caused. In the absence of cleaning, the lifetime of the sensor is dependent on the total mass deposited. As a result, the lifetime is made essentially constant by this approach, because each sensing operation is made to give rise to a constant amount of deposited particle mass. This means the lifetime can be predicted more accurately.

The invention describes a laser sensor module () for particle density detection. The laser sensor module () comprising at least one first laser (), at least one first detector () and at least one electrical driver (). The first laser () is adapted to emit first laser light in reaction to signals provided by the at least one electrical driver (). The at least one first detector () is adapted to detect a first self-mixing interference signal of an optical wave within a first laser cavity of the first laser (). The first self-mixing interference signal is caused by first reflected laser light reentering the first laser cavity, the first reflected laser light being reflected by a particle receiving at least a part of the first laser light. The laser sensor module () is adapted to reduce multiple counts of the particle. The invention further describes a related method and computer program product.

A method of dust processing comprises measuring (PC1) a first amount of particles of a first size (e.g. PM10), and measuring (PC2) a second amount of particles of a second size (e.g. PM2.5) smaller than the first size. In accordance with the invention, it is determined (&#x394;) whether the first amount exceeds the second amount by a predefined threshold. If so, a robotic vacuum cleaner (RVC) may be prompted to start cleaning a room.
