Abstract: A system (10) includes a real-time locating system (RTLS) (12) configured to track locations of tags (14, 15) in a monitored area. A non-transitory storage medium stores, a map (30) of the monitored area; a nodes database (32) storing information on nodes (18); and a pathogen database (34) storing infectious transmission information. The non-transitory storage medium includes instructions readable and executable by an electronic processor to perform an infectious disease transmission tracking method (100) including: computing a pathway (35) on the map of at least one infected node using locations of the tag wherein an infected node has a non-zero infection likelihood; computing an infectious zone (36) on the map along the pathway; for each node contacting the infectious zone, adjusting the infection likelihood of the contacting node and designating the contacting node as an infected node if the updated infection likelihood of the contacting node satisfies an infected criterion.

Abstract: A method for modifying data from a Real-Time Location System (RTLS) involving: receiving building arrangement information having two locations and one or more identifiable characteristics of the two locations; obtaining identifying information of at least one tag and at least two sensors in the RTLS; generating a mapping of the identifying information with the one or more identifiable characteristics of the two locations; receiving location information of the at least one tag based on the mapping, the location information indicating a presence of the at least one tag in the two locations at separate times; determining that the location information includes at least one gap because the at least one tag cannot proceed directly between the two locations in the building arrangement information; and updating the location information based on an interpolation of the location information to fill in the at least one gap.

Abstract: The invention relates to a method and to an apparatus that enables the ambience of e.g. hospital rooms to adapt according the scheduled or non-scheduled activities throughout the day. The ambience generated by lights, sound devices, image, movie displays and other devices is controlled by an ambience controller (100) in dependence of day phases defined by a patient's day schedule or in dependence of other non-scheduled phases which may have been initiated in dependence of a trigger signal (215, 216) generated in response to activities such as the entering of a caterer.

Abstract: A lighting system comprises a light source having an exit window and an electrically controllable light processing arrangement, in the form of a grid of cells lying in a plane parallel to the exit window. Each cell has a cell wall formed as electrically switchable element which is switchable between at least two processing modes. The cell wall surrounds an opening, such that light emitted in a normal direction from the light source exit window is not processed, and light passing at an angle to the normal direction greater than a threshold angle is processed by the cell wall for color and/or intensity control.

Abstract: A lighting system uses an array of lighting elements which provide light in different directions. The intensity of the lighting elements is controlled in dependence on a time-varying parameter related to at least one of a position of a light emitting or light reflecting body, and an intensity, color or color temperature of the light emitted or reflected by the body, such that the system can simulate directional sunlight.

Abstract: A lighting system has a recessed panel (light source or window) and a side wall or a set of side walls around the recess. The side wall (or at least one of the side walls), is provided with a lighting arrangement for controlling the color of illumination and/or shape from which light is emitted from the side wall or side walls. This can be used to replicate the sharp lighting boundaries that arise on the recess walls from sun illumination through a skylight, or else they can be used to provide general illumination around a window.

Abstract: The invention relates to a user interface (100) for use by a patient, e.g. a stroke victim, for controlling video and images displayed on a patient display (170). The user interface includes display components (111-113) for displaying images and video created from visual object data. The display components are selectable by the patient so that by selection of display component, images or video displayed on the display component will be displayed in full on the patient display. The user interface is configured so that the display components resemble corresponding display units (171-173) of the patient display. The display components and other buttons may have a size and may be centered in the user interface (100) to ease use of the user interface for patients having a reduced ability to operate buttons on a user interface.
