Abstract: An aspect concerns a gaseous fluid monitor for monitoring properties of a gaseous fluid, including particle size. The gaseous fluid monitor may include a detector configured to provide a detection of at least one of the properties of the gaseous fluid, which detector may include a particulate matter sensor configured to detect first particles and second particles suspended in the gaseous fluid and to provide, as part of the detection, a first concentration of the first particles, and a second concentration of the second particles. The gaseous fluid monitor may include a classifier configured to classify the detection into the pre-defined set of classes. Another aspect concerns a method for monitoring the properties of the gaseous fluid. The method may include detecting first particles and second particles, and may further include classifying the detection into a pre-defined set of classes.

Abstract: A detector is configured to be mounted to a container. The detector has a housing and a mounting arrangement for mounting the housing to a container. A sensor arrangement includes a sensor to monitor the container and to generate a sensor output signal in response to a sensed container event. A processor executes a machine learning algorithm trained to determine a class of the sensed container event for determining occupancy of the container from the sensor output signal, where the control system is configured to provide an output based on the class of sensed container event determined by the machine learning algorithm.

Abstract: There is described a method for identifying potential personal safety incidents of an individual (5), the method comprising the steps of receiving a sample data set comprising motion data and vital sign data from one or more sensors (14, 16, 18) associated with the individual, determining one or more motion features and one or more vital sign features, and determining whether the sample data set is indicative of a potential personal safety incident of the individual based on a model and at least one of the motion and vital sign features. The sensors can be provided by a fitness tracker and/or an activity tracker, such as a smartphone and/or a smart watch. The method can also include determining one or more responses such as alerting another party of the potential personal safety incident or triggering a deterrent mechanism.

Abstract: One embodiment relates to computer implemented method comprising: controlling an active reflected wave detector to measure wave reflections from an environment to receive measured wave reflection data that is obtained by the active reflected wave detector; determining an occupancy level indicative of how many people are present in the environment; and controlling, in dependence on the occupancy level, a fall detector that is operable to detect whether a person in the environment has fallen based on the measured wave reflection data.
