Patent number: 8111021Abstract: A method of controlling a lighting system includes a learning procedure. The lighting system includes lighting modules and a controlling device. The lighting modules are arbitrarily arranged, and each lighting module can communicate with neighboring lighting modules via communication units arranged at sides of the lighting module. The learning procedure defines a lighting module arrangement and a communication network for communication between the controlling device and the lighting modules. During the learning procedure, a token is forwarded from one lighting module to another lighting module, while ensuring that all lighting modules are visited by the token. Further, geometric information about how the lighting modules are arranged in relation to each other is generated.Type: GrantFiled: November 28, 2006Date of Patent: February 7, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Pieter Jacob Snijder, Anthonie Hendrik Bergman, Gerritjan Henri Cowan

Publication number: 20100177909Abstract: A beamforming system (ASY) comprises a modular transducer assembly (MTA) composed of a plurality of transducer modules (TM1, TM2, TM3). A transducer module comprises a plurality of interfaces having different geometrical orientations. An interface allows the transducer module to be physically coupled to another transducer module. In a reconnaissance phase, the beamforming system identifies transducer modules that are present in the modular transducer assembly (MTA). The beamforming system further identifies a structure in accordance with which the transducer modules have been physically coupled to each other. In a configuration phase, the beamforming system defines a signal relationship between the transducer modules on the basis of identification data that has been obtained in the reconnaissance phase and a desired directional response pattern.Type: ApplicationFiled: June 4, 2008Publication date: July 15, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Ronaldus Maria Aarts, Pieter Jacob Snijder

Publication number: 20080309259Abstract: This invention relates to method of controlling a lighting system including a plurality of polygonal lighting modules and a controlling device, which are able to communicate with each other. The lighting modules are arbitrarily arrange able, since each lighting module is able to communicate with neighboring lighting modules via communication units arranged at several sides of the lighting module. The method includes a learning procedure for defining a lighting module arrangement and a communication network for communication between the controlling device and the lighting modules. During the learning procedure a token is forwarded from lighting module to lighting module, while ensuring that all lighting modules are visited by the token; and geometric information about how the lighting modules are arranged in relation to each other is generated.Type: ApplicationFiled: November 28, 2006Publication date: December 18, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Pieter Jacob Snijder, Anthonie Hendrik Bergman, Gerrit Jan Henri Cowan

Patent number: 7446744Abstract: The invention relates to a display device comprising a plurality of light emitting elements (1), wherein at least one of the elements has an associated capacitor (C1). The display device comprises pre-charging means (7;8) for generating a pre-charge signal for charging the associated capacitor (C1) at least partly. The pre-charging means (7;8) are adapted for generating a pre-charge signal comprising at least a first pre-charge signal in a first pre-charge stage and a second pre-charge signal in a second pre-charge stage. The pre-charge signal preferably comprises a current pre-charge signal followed by a voltage pre-charge signal. The combined pre-charge signal has the advantage of fast, but accurate pre-charging.Type: GrantFiled: November 4, 2003Date of Patent: November 4, 2008Assignee: Koninklijke Philips Electronics N.V.Inventors: Markus Heinrich Klein, Douwe Thomas De Jong, Serge Leon Gerard Toussaint, Adrianus Sempel, Remco Los, Pieter Jacob Snijder, Olaf Gielkens

Publication number: 20080265800Abstract: This invention relates to a LED lighting device having a plurality of LEDs, and a LED drive system. The LED drive system includes basic light circuitry for generating, for each LED, a basic current causing continuous basic light output of the LED. Additionally, the LED drive system includes flash light circuitry, for generating, for each LED, a momentary flash current through the LED, which causes a momentary flash light output. An average current amplitude of the flash current is higher than an average current amplitude of said basic current. Thereby flashes, or twinkles, will be observed by a person watching the LED lighting device.Type: ApplicationFiled: November 14, 2006Publication date: October 30, 2008Applicant: Koninklijke Philips Electronics, N.V.Inventor: Pieter Jacob Snijder

Patent number: 7009959Abstract: The multiple access communication system according to the invention comprises at least one primary station (2) and a plurality of secondary stations (32, 34, 36). The primary station (2) and the secondary stations (32, 34, 36) are interconnected via a network, e.g. a coaxial cable network or a hybrid fiber/coax network. The secondary stations (32, 34, 36) can transmit return signals in a return signal frequency band to the primary station (2). However, the secondary stations (32, 34, 36) are arranged for transmitting the return signals in only a part of the return signal frequency band containing relatively little noise, e.g. the upper part of the return signal frequency band. The network comprises means (40) for mapping the return signals of the secondary stations (32, 34, 36) onto the full return signal frequency band, e.g. by means of a frequency converter (48, 50).Type: GrantFiled: September 8, 2000Date of Patent: March 7, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Pieter Jacob Snijder, Carel Jan Leendert Van Driel, Robert Marinus Hanenberg
