Abstract: A method for routing a medical alert to a selected staff member 151-153, the method comprising receiving an alert signal generated by an alert generation device 121-126, obtaining the current location and identity of multiple staff members from a location tracking system 141-146 configured to track the locations of the multiple staff members, upon receiving the alert signal, selecting from the multiple staff members a selected staff member by at least determining that the distance between a location of the alert generation device and the location of the selected staff member is shorter than the distance between the location of the alert generation device and the location of at least one of the multiple staff members other than the selected staff member, and sending an alert signal to an individually addressable mobile device associated with the selected staff member.

Abstract: The invention relates to an identification sensor (100) which is configured with two passage sensors (101, 102) and with an ID receiver (103). The ID receiver is configured to receive wirelessly transmitted radio frequency signals from a personal transmitter 111. The radio frequency signal is an ID signal which contains ID information which can be used for identifying the person carrying the personal transmitter (111), e.g. by retrieving further ID information form a database (112). Passage signals generated by the two passage sensors (101, 102) are compared in order to determine the motion direction of the user relative to the sensors. An output signal containing information about the ID information and the motion direction is generated. The output signal can be used for controlling e.g. ambient light in a patient room to satisfy working conditions for a doctor who enters the room and to adjust light to create a suitable atmosphere for the patient when the doctor leaves the room.

Abstract: A lighting system comprises a set of light sources and a remote control unit. The remote control unit comprises a user interface through which a user may identify an area in an image and a light source. The identified image area is linked with the light source and color information of the identified image area is transmitted to the light source. The light source is thereby enabled to adapt its light output to the color information. A user is thereby enabled to pick the color to be outputted by a light source by selecting an area in an image displayed on the remote control unit. The remote control unit may be part of a mobile telephone, a tablet computer, an electronic photo frame, or a television screen.

Abstract: There is provides an illumination system which comprises a plurality of luminaries or light sources. Each luminary or light source comprises a light driver capable of receiving and storing a dynamic light effect pattern, and from the dynamic light effect pattern creating a light effect. The color and/or intensity of the luminary or light source is thereby dynamically varied. The light driver is further arranged to embed data in the light effect. Each luminary or light source further comprises a light emitter for emitting the light effect comprising the encoded data. A light detector is arranged to receive light emitted by other luminaries or light sources in the illumination system. A light decoder is arranged to decode data out of light received by the detector and arranged to determine the intensity of the light received.

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 (100) comprising a central lighting device (111), at least one satellite lighting device (121, 131), and a controller (141) for adjusting light settings, is provided. The controller is arranged for transmitting, in response to a user request (140), an association request over a first communication link (142). The central lighting device is arranged for receiving the association request and re-transmitting the association request over a second communication link by means of coded light (112). The satellite lighting device is arranged for transmitting, in response to receiving the association request, its identifier to the central lighting device. The identifier is only transmitted if an association process is enabled. The association process is enabled, in response to a user request, during a limited time period. The central lighting device is further arranged for associating, in response to receiving the identifier, the satellite lighting device with the central lighting device.
