摘要： The invention provides a system for determining a risk level of a pollen-induced allergy of a user. The system comprises an input for receiving information relating to a pollen level in a location, an input for receiving information relating to a particulate matter level in the location and an input for receiving information relating to a sensitivity of a user to pollen allergen. The system further comprises a processor which is adapted to determine the risk level by taking account of the information relating to a pollen level, the information relating to a particulate matter level and the information relating to a sensitivity of the user to pollen allergen. A user interlace communicates the risk level in the location to the user.

摘要： A system is for estimating a remaining lifetime of an aldehyde filter. The system comprises aa aldehyde filter (14) through which at least a portion of the gas is to be passed for removing aldehyde (10) from the gas (12) and a detecting medium (16) through which at least a portion of the gas is to be passed comprising photoluminescent carbon-based dots (18), a light source for emitting an excitation light (E) through the detecting medium for exciting the carbon-based dots which thereby emit luminescent light (L), a detector (28) for detecting the luminescent light (L), the luminescent light (L) having a luminescence property; and a controller (30) for determining information relating to intensity of a red, a green or a blue component of the luminescence property and estimating a remaining lifetime of the aldehyde filter from the determined information.

摘要： The invention provides a system for alerting a second subject (e.g. a parent) based on a wellbeing state of a first subject (e.g. a child) when the first subject is sleeping in the same room as the second subject. An arrangement of sensors is used for sensing data from the first subject and a processor is configured to determine the presence of the first subject from the sensing data. Based on the first subject being present, the processor is further configured to determine the state of the first subject based on the sensing data from the arrangement of sensors and then determine whether to alert the second subject based on the state of the first subject. An alarm is provided for alerting the second subject.

摘要： A particle sensor is provided for sensing the number or mass concentration of particles within a particular particle size range, the particles having a particle size distribution. The sensor comprises a light source (14) for providing light which is scattered by the particles to generate scattered light; a light detector (16, 18) for detecting the scattered light to provide a light detector signal; and a controller (24) for analyzing the light detector signal to determine information relating to the particle size distribution. Based on that information relating to the particle size distribution, the controller selects a mode of operation of the particle sensor to sense the particles only within the particular size range.

摘要： A particle or pollen sensor comprises an array of relative humidity sensors. A change in relative humidity is representative of a particle or pollen in contact with one or more of the sensors. A size and/or shape of a particle or pollen in contact with one or more of the sensors is optionally also determined based on the number and/or configuration of sensors. From this information, a particle or pollen type is determined.

摘要： A particle sensing system is for sensing particles entrained in a fluid. The system comprises a flow channel having a longitudinal direction along which the fluid is to be passed, a heating arrangement for heating the fluid and thereby applying a positive thermophoretic force on the fluid in a direction perpendicular to the longitudinal direction of the flow channel and a first sensor for sensing the particles in the fluid after heating by the heating arrangement. The thermophoretic force increases the concentration of the particles at the first sensor.

摘要： A particle sensing apparatus is provided for determining particle concentration in a fluid, e.g. air. The apparatus is based on fluid-flow passageway having an upstream inlet to receive the fluid and a downstream outlet to exhaust the fluid. It also includes a recirculation passageway in fluid communication with the fluid-flow passageway. Between them, the fluid-flow passageway and the recirculation passageway define a recirculation loop. A first particle sensor is located in the recirculation loop, and other sensors may also be present at other options. A force applicator is included in the fluid-flow passageway to apply a force to the particles entrained in the fluid. The force is used to direct some or all of the particles into the recirculation loop. This provides a choice between increasing the detection limit or the detection range. A processor determines the concentration of particles in the fluid based on the concentration of particles detected at the first particle sensor.
