Abstract: The present invention relates to a control engine configured to control one or more UV-C light sources configured to emit UV-C light in a space. The control engine comprising circuitry configured to execute: a reference image acquiring function configured to construct a reference image using reference radar sensor signals received, at a first time-instance, from a plurality of radar sensors arranged in the space; a probing radar acquiring function configured to construct a probing image using probing radar sensor signals received, at a second time-instance at which the one or more UV-C light sources are inactive, from the plurality of radar sensors, wherein the second time-instance is after the first time-instance; and a control function. The control function is configured to obtain a difference metric between the probing image and the reference image. Upon the difference metric being smaller than a threshold, the control function is configured to activate the one or more UV-C light sources. Upon the difference metric being equal to or above the threshold, the control function is configured to issue an alarm event.

Abstract: A method for determining a position of each of a plurality of electronic devices belonging to a common system of electronic devices is disclosed. The method comprising, for each of the plurality of electronic devices: detecting presence of a person in a predetermined presence volume associated with the electronic device; in response to detecting presence of a person in the predetermined presence volume, wirelessly transmitting, from the electronic device, an ID-message comprising a device-ID of the electronic device; at a portable electronic device, receiving the ID-message and extracting the device-ID of the electronic device; and mapping a current position of the portable electronic device as a position of the electronic device for which device-ID has been extracted.

Abstract: A lighting system control engine for controlling a light environment at different locations is disclosed. The lighting system control engine comprising circuitry configured to: execute a light profile setting function configured to manipulate a template light profile describing illuminance and spectrum over a time period such that a first manipulated light profile associated with a first location and a second manipulated light profile associated with a second location are formed, said first and second manipulated light profiles are different, and said first and second locations are different; and execute a light source control function configured to, over time, control lighting at the first location in accordance with the first manipulated light profile and to, over time, control lighting the second location in accordance with the second manipulated light profile. Also, a lighting system including the control engine and a method for controlling light environments at different locations are disclosed.

Abstract: The present inventive concept relates to an illumination system and a method for controlling an illumination system configured to illuminate a zone, the illumination system being further configured to serve a plurality of individuals. The method comprising: identifying one or more individuals of the plurality of individuals present in the zone; for each individual present in the zone, obtaining a respective target light profile, each target light profile comprising time-resolved information about circadian stimuli and color temperatures of light that the respective individual is to be exposed to; assigning a priority to each individual of the plurality of individuals present in the zone based on the respective target light profile; determining a proportion of the plurality of individuals present in the zone; and upon the proportion of the plurality of individuals present in the zone is equal to or above a threshold: controlling the illumination system such that a circadian stimulus of light illuminating the zone is higher than a circadian stimulus of the target light profile associated with the individual having a highest assigned priority.
