Patent number: 9184497Abstract: A lighting device, such as a replacement lighting device, comprising a light source (LS), e.g. LEDs, for producing light along an optical axis (OA). A heat sink (HS) made of a material with an electrical resistivity being less than 0.01 ?m, e.g. a metallic heat sink being a part of the housing, transports heat away from the light source (LS). A Radio Frequency (RF) communication circuit (CC) connected to an antenna (A) serves to enable RF signal communication, e.g. to control the device via a remote control. Metallic components, including the heat sink (HS), having an extension larger than 1/10 of a wavelength of the RF signal are arranged below a virtual plane (VP) drawn orthogonal to the optical axis (OA) and going through the antenna (A). Hereby a compact device can be obtained, and still a satisfying RF radiation pattern can be obtained. The antenna can be a wire antenna or a PCB antenna, e.g. a PIFA or a IFA type antenna.Type: GrantFiled: June 4, 2010Date of Patent: November 10, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Bingzhou Chen, Guoping Zhang, Martijn Henri Richard Lankhorst, Roger Henri Denker, Jeroen Snelten, Dennis Johannes Antonius Claessens, Ludo Haenen, Jacobus Hubertus Anna Selen, Patrick Van Kooten

Publication number: 20100214827Abstract: A module comprises a bus invert encoder (24) for determining whether a set of data bits should be inverted prior to transmission over a communication bus. The bus invert encoder (24) produces a bus invert signal BI which controls a selective inversion means (28), for example a multiplexer. A partial fault detection encoder (32) determines one or more temporary check bits from the set of data bits, substantially in parallel with the bus invert encoder (24). Thus, the one or more temporary check bits are determined based on the assumption that the set of data bits are to be transmitted without inversion from the selective inversion means (28). A logic unit (34) is provided for correcting the one or more temporary check bits, if necessary, based on the bus invert signal produced by the bus invert encoder (24).Type: ApplicationFiled: August 19, 2005Publication date: August 26, 2010Applicant: NXP B.V.Inventors: Martijn Henri Richard Lankhorst, Franciscus P.
