Patent number: 10545554Abstract: The resource metering system comprises: an end-point device (25) consuming a resource, in particular for usage in a building (2) or in an outdoor lighting system, said device comprising a detection unit that produces status information and an indicator of usefulness; a smart meter (20) comprising: a communication circuitry provided with an interface adapted for receiving from said device status information and said indicator of usefulness; a metrology device connected to a medium (17) that provides the resource to said device; and a control circuitry connected to the metrology device for collecting resource consumption data, the control circuitry being connected to the communication circuitry and adapted to produce monitoring data to be securely transmitted to a server (10) after processing the status information and said indicator. Monitoring data are used when determining consumption tariffs, so as to encourage energy efficient usage of the device.Type: GrantFiled: October 24, 2011Date of Patent: January 28, 2020Assignee: SIGNIFY HOLDING B.V.Inventors: Robert Paul Koster, Klaus Kursawe, Alphons Antonius Maria Lambertus Bruekers, Paulus Mathias Hubertus Mechtildis Anton Gorissen, Ileana R.

Patent number: 9185133Abstract: The invention provides methods, devices (102, 110, 124, 136) and communication systems (100) for establishing end-to-end secure connections and for securely communicating data packets. Such a communication system (100) comprises a first device (124, 136), an intermediate device (110) and a second device (102). The first device (124, 136) communications via a first network (120), which is based on a first transport protocol and a first transport security protocol with the intermediate device (110). The second device (102) communications via a second network, which is based on a second transport protocol and a second transport security protocol with the intermediate device (110). The intermediate device (110) modifies packets received via first network to packets suitable for communication via the second network, and vice versa. The first device (124, 136) is able to reconstruct a header of a received packet as if the packet was sent via the second network (108) and its transport and security protocols.Type: GrantFiled: July 24, 2012Date of Patent: November 10, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Sye Loong Keoh, Oscar Garcia Morchon, Sandeep Shankaran Kumar, Martina Brachmann, Bozena Erdmann

Publication number: 20150263861Abstract: The present invention relates to verification of the authenticity of a lighting device. There is provided a lighting device which is capable of emitting coded light. The lighting device has a challenge receiver, arranged to receive a challenge, and a response transmitter, arranged to generate and transmit a response to the challenge. The response is generated by means of the challenge and a secret key in combination. Furthermore, there is provided a corresponding verification device generating the challenge and providing it to the lighting device, and analyzing the response in order to check the authenticity of the lighting device.Type: ApplicationFiled: September 12, 2013Publication date: September 17, 2015Inventors: Sandeep Shankaran Kumar, Oscar Garcia Morchon, Sye Loong Keoh, Theodorusb Jacobus Johannes Denteneer, Lorenzo Feri
