Abstract: 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.

Abstract: There is provided a lighting device (100) comprising a housing comprising a frangible light exit window (110) and a fitting (120) including a first electrical connector (122) inside said housing. Within the housing there is a carrier assembly (130) comprising a plurality of SSL elements (132), and a second electrical connector (134) in contact with the first electrical connector (122). The second electrical connector (134) is held in contact with the first electrical connector (122) by the light exit window (110). This lighting device is relatively safe as if the light exit window (110) breaks the electrical components of the carrier assembly (130) may not be live.

Abstract: The present application relates to an apparatus for purifying and/or humidifying air, and a related method for purifying and/or humidifying air. The apparatus comprises a rotary filter (1), a fan (9, 10) for passing air through the rotary filter (1), and a reservoir (4, 5), and wherein the rotation speed of the rotary filter (1) and the settings of the fan (9, 10) depend on the ambient relative humidity and ambient gas pollutant concentration. The apparatus combines the feature of chemisorption with the use of a rotary filter (1), thereby providing an apparatus which is able to purify air and/or regulate the ambient humidity based on humidity levels and levels of a target gas pollutant in the air. The invention removes the need for a pump for liquid transport, removes the need for frequent and expensive filter changes by the user, and instead only requires the user to periodically refresh the filtration solution in the reservoir (4, 5).

Abstract: A method comprising: providing a light source in the form of a luminaire or lamp operable to emit light into an environment, the light source being activated from a time at which the light source is first deployed into said environment to enable the light to be controlled via a first communication channel, but having a capability for the light to be controlled via a second communication channel being electronically deactivated at the time of deployment; then after the time of deployment of the light source into the environment, receiving a request to upgrade the light source; and in response to this request, sending activation data to the light source or a user of the light source, thereby enabling the capability for the light to be controlled via the second communication channel to be electronically activated.

Abstract: The invention describes a modular fluid sensing system comprising a fluid sensing terminal (150) and removable fluid channel units (101, 102, 103). The fluid channel units (101, 102, 103) comprise or can be combined with fluid treatment units as filters, sensors and seals. The fluid channel units (101, 102, 103) can be combined in accordance with the present needs of the user of the fluid sensing system. The invention therefore enables a reconfigurable channel system with reconfigurable measurement and treatment options within a fluid sensing system.

Abstract: An illuminating member (4) that, independent of any image content, comprises a central region (5) and an enclosing region (6), wherein said enclosing region (6) is adapted to emit light of lower quality than the light emitted by the central region (5). The illuminating member is adapted to illuminate a display panel (2) of a display device. By having the enclosing region emit light of lower brightness (dimming) a significant power reduction can be achieved for a wide range of typical images while largely maintaining the perceived image quality. Further, by using light emitting elements of lower quality for the enclosing region, manufacturing costs may be reduced while largely maintaining the perceived image quality.
