  • Patent number: 10034340
    Abstract: A network switch (5) for example a PoE switch, is operable to control supply of electrical power to individual luminaires (1,2) in a lighting network. The luminaires receive both electrical power for operation and signals to switch on and off through a common cable connection (9) such as an Ethernet connection. When switched on, each luminaire sends a signal repeatedly towards the Po E switch until switched off and the switch (5) supplies power to the luminaire while successive signals are received within a period less than a predetermined shut off period (?). In this way, power to the luminaire can be disconnected to avoid consumption of standby power when not in use.

  • Patent number: 9979559
    Abstract: The disclosure relates to an application server which provides a user of a mobile device with a location based service controlling functionality of an environment external to the mobile device, where the control of the functionality is conditional on an estimated location of the mobile device as estimated by a positioning algorithm. A feedback module is configured to infer a quality of the estimation from the behavior of the user, based on a manner in which the user interacts or attempts to interact with the functionality of the location based service. The feedback module then sends feedback of the inferred quality to the positioning algorithm.
