Patent number: 9686030Abstract: Efficiency for mixing audio signals from one or more portable user devices in an audio system employing a number of docking station is achieved by a docking station that includes a controller for detecting the presence of an activated mixer associated with another docking station in the system. The controller activates its associated mixer when no activated mixer associated with another docking host in the system is detected. When its associated mixer is activated, the controller in the one docking station causes its associated mixer to be connected both to the audio sound system for supplying an input signal thereto and indirectly to the output(s) of the one or more portable devices. Transfer of mixing from one docking station to another in the same system upon the occurrence of a particularly defined event is also described.Type: GrantFiled: November 9, 2012Date of Patent: June 20, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Koen Johanna Guillaume Holtman, Walter Dees

Patent number: 9538616Abstract: The present invention defines a HTTP or CoAP request message that combines one or more HTTP or CoAP requests along with timing information (432-1). The message is sent by a control device (132) to a network proxy (i.e. a network router (112)) via a control network (120). The network proxy decodes the message and subsequently controls destination devices, in particular luminaires (L1, L2, L3, L4), in a timed manner using the HTTP or CoAP requests. The network proxy is application-independent and also enables control of third party HTTP-or CoAP-based devices that are not aware of timed requests. Improved timing performance is obtained by choosing the network proxy location “close by”, in terms of network hops and/or latency, to the destination devices to be controlled.Type: GrantFiled: July 25, 2013Date of Patent: January 3, 2017Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Esko Olavi Dijk, Koen Johanna Guillaume Holtman

Publication number: 20160203706Abstract: The invention relates to methods and devices for exchanging control information in mixed radio systems. Security is added in cases where a user of a first wireless device (102) wants to command a second wireless device (101) to perform a certain action. The first and second wireless devices use different radio systems or standards (e.g. WiFi and ZigBee/802.15.4) but their radios do operate on the same frequency band (e.g. 2.4 GHz). To add security, the second wireless device (101) will only accept certain commands if it can detect that the first wireless device (102) is physically close-by. To prove that the first device (102) is close-by, it emits a predetermined energy pattern, e.g., one or more packets (the contents do not matter, while their lengths/time spacing may) using its radio system. At the same time, the second wireless device (101) measures the energy in one or more of its overlapping radio channels to detect that the first wireless device (102) is close by and execute the commanded action.Type: ApplicationFiled: August 20, 2014Publication date: July 14, 2016Applicant: PHILIPS LIGHTING HOLDING B.V.Inventors: KOEN JOHANNA GUILLAUME HOLTMAN, BOZENA ERDMANN
