Patent number: 9179516Abstract: This invention relates to a color controlled light source comprising a plurality of colored light elements, and a plurality of (filtered) photo detectors, having different spectral characteristics covering all or most of the total spectrum of the light elements. The (filtered) photo detectors detect the light output of the light source, and generate corresponding detection signals. The light source further has a color control unit for generating driving signals to the light elements on the basis of the detection signals and a predetermined target color point of the light output of the light source, and a modulator for individual signature modulation of the driving signal to each one of said light elements. A corresponding demodulator is provided for demodulation of the detection signals and extraction, from each detection signal, of actual values of the light outputs of the light elements.Type: GrantFiled: October 23, 2007Date of Patent: November 3, 2015Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Eduard J. Meijer, John B. Mills, Volkmar Schulz, Bernd Ackerman, Lorenzo Feri, Hans M. B. Boeve

Patent number: 8237436Abstract: Compensation coil functionality and flip coil functionality are combined into a single combination coil that is placed under an angle ? with respect to the length direction of a magneto-resistive sensor element. The angle ? substantially deviates from 0° and 90°. This configuration enables to reduce the width of the current line of the planar combination coil, to reduce the effective threshold for sensor element switching, and to include features to simplify a 2D sensor design.Type: GrantFiled: February 13, 2008Date of Patent: August 7, 2012Assignee: NXP B.V.Inventors: Hans M. B. Boeve, Teunis J. Ikkink, Haris Duric, Johannes P. M. Van Lammeren

Patent number: 7895002Abstract: Devices comprising sensor arrangements for providing first field information defining at least parts of first fields and for providing second field information defining at least parts of second fields are provided with updaters for updating parameters of the first and/or second fields via criterion-dependent iterations, to become more reliable and user friendly. The fields may be earth gravitational fields and/or earth magnetic fields and/or further fields. The parameters comprise magnitudes of the fields and dot products of the fields. The criterion-dependent iterations comprise magnitude functions and dot product functions. The magnitude functions define new magnitudes being functions of old magnitudes and of updated magnitudes and the dot product functions define new dot products being functions of old dot products and of updated dot products.Type: GrantFiled: April 27, 2006Date of Patent: February 22, 2011Assignee: NXP B.V.Inventors: Teunis J. Ikkink, Hans M. B. Boeve, Gerjan Van De Walle

Patent number: 7791937Abstract: The invention relates to a Magnetic memory system (1, 20) which comprises an information layer (13) and a sensor (2, 22) for cooperating with the information layer (13). The information layer (13) comprises a pattern of magnetic bits (4a, 4b, 4c, 4d, 24a, 24c, 24d) which constitutes an array of bit locations. A bit magnetic field (3a, 3b, 3c, 3d) at a bit location represents a logical value (LO, L1/2, L1). The sensor (2, 22) comprises a magnetoresistive element (6, 26) comprising a fixed magnetic layer (7) and a free magnetic layer (8). The free magnetic layer (8) has a magnetization axis (10) along which the free magnetic layer retains a free magnetization direction (1 Ib, 1 Ic, 21b, 21c).Type: GrantFiled: January 19, 2006Date of Patent: September 7, 2010Assignee: NXP B.V.Inventors: Friso J.

Publication number: 20100140146Abstract: Magnetic Particle Imaging (MPI) requires high-performing tracer materials that are highly magnetic monodispersed particles with fast remagnetization behaviour. Known separation techniques only allow for fractionation of magnetic particles based on differences in magnetic volume. Proposed is a separation method, which allows for separation of magnetic particles with respect to their dynamic response onto an oscillating high gradient magnetic field.Type: ApplicationFiled: February 13, 2008Publication date: June 10, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Denis Markov, Hans M.B Boeve

Patent number: 7660180Abstract: A thermally programmable memory has a programmable element (20) of a thermally programmable resistance preferably of phase change material, material and a blown antifuse (80) located adjacent to the programmable material. Such a blown antifuse has a dielectric layer (100) surrounded by conductive layers (90, 110) to enable a brief high voltage to be applied across the dielectric to blow a small hole in the dielectric during manufacture to form a small conductive path which can be used as a tiny electrical heater for programming the material. Due to the current confinement by the hole, the volume of the material that must be heated in order to switch to a highly-resistive state is very small. As a result the programming power can be low.Type: GrantFiled: November 24, 2005Date of Patent: February 9, 2010Assignee: NXP B.V.Inventors: Hans M. B. Boeve, Karen Attenborough, Godefridus A. M. Hurkx, Prabhat Agarwal, Hendrik G. A. Huizing, Michael A. A. In'T Zandt, Jan W. Slotboom

Patent number: 7579968Abstract: A data processing circuit comprises an encoder circuit for encoding a data word, wherein each digit may have any one of three or more digit values. The data word is encoded so that digit counts in the data word satisfy predetermined criteria (the digit counts are counts of the numbers of the digits in the encoded data word that assume respective digit values). The encoder defines at least two digit maps, each digit map defining assignments of each of the available digit values to a respective different output digit value. The encoder selects at least two groups of digits within the input data word. Each group is associated with a respective one of the digit maps, the groups being selected so that when each digit map has been applied selectively to the digits from its associated group, digit counts of the number of times respective digit values occur in the data word will satisfy predetermined criteria.Type: GrantFiled: July 19, 2005Date of Patent: August 25, 2009Assignee: NXP B.V.Inventors: Victor M.
