Publication number: 20110314897Abstract: A sensor chip (1030) for gas has cells (200) for emitting and receiving ultrasound and is configured for a sufficiently large frequency range and for measuring concentration of at least one of the gas components based on at least two responses within the range. The frequency range can be achieved by varying the size of cell membranes (230), varying bias voltages, and/or varying air pressure for an array (205) of cMUTs or MEMS microphones. The sensor chip can be applied in, for example, capnography. A measurement air chamber (515) is implemented in the respiratory pathway (400), and it and/or the pathway may be designed to reduce turbulence in the exhaled breath (120) subject to ultrasound interrogation. The chip (1030) can be implemented as self-contained in the monitoring of parameters, obviating the need for off-chip sensors.Type: ApplicationFiled: March 10, 2010Publication date: December 29, 2011Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Martijn Schellekens, Josephus Arnoldus Henricus Maria Kahlman, Martinus Gernardus Van Der Mark, Peter Dirksen

Patent number: 8059514Abstract: A visible pattern is obtained by modulating the digital sum value. Because the digital sum value modulation allows the choice of several different channel bits groups between DC control points, the selection of a group of channel bits resulting in a change of reflection. This creation of a visible pattern is highly suitable for Blueray as the parity preserving property of the channel code guarantees disparity inversion by the DC-control bit, which keeps the DSV excursions between hard limits. As a result only small DSV deliberate variations are required to produce a grating, which will not deteriorate the bit-detection margin of the optical disc.Type: GrantFiled: August 22, 2008Date of Patent: November 15, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Jacobus Maarten Den Hollander, Josephus Arnoldus Henricus Maria Kahlman

Publication number: 20110007178Abstract: A biosensing device for sensing brightness of a bio sample from frames of a video signal, has circuitry (40) arranged to receive the video signal and determine a brightness of a given area (110) of one or more of the frames in real time. A controller (50) adjusts boundaries of the given area, and uses the measures of brightness for different boundaries, to determine location of edges of the sample, then sets the boundaries according to the edges for subsequent measurements of brightness.

Patent number: 7852238Abstract: A coder is fed with pre-coded data such that the absolute value of the RDS of the code words as produced by the coder is limited. This is achieved by ensuring that in a group of 2 code words the RDS of the first code word is compensated by the RDS of the second conde word. The RDS at the end of the second code word is then zero and the excursions of the RDS from the start of the first code word until the end of the second code word are limited because there are only a limited number of bits that can contribute to an increase of the absolute value of the RDS. This principle can easily be applied to the 17PP coder.Type: GrantFiled: October 7, 2004Date of Patent: December 14, 2010Assignee: Koninklijke Philips Electronics N.V.Inventor: Josephus Arnoldus Henricus Maria Kahlman

Publication number: 20100267165Abstract: The invention relates to a microelectronic sensor device for the examination of target particles (1) that are bound to binding sites (3) at the binding surface (12) of a carrier (11). In a preferred embodiment, an input light beam (L1) is transmitted into the carrier (11), where a frustrated total internal reflection (FTIR) takes place at the binding surface (12). The amount of light in a resulting output light beam (L2) is detected by a light detector (31) and provides information about the presence of target particles at the binding surface. Moreover, an actuation unit (50) induces movements of the bound target particles (1) by an interaction with a magnetic field (B) or an electric field, particularly with a given modulation frequency (COIn), such that by a demodulation of the detector signal (S) effects of the target particles can be distinguished from background.Type: ApplicationFiled: October 31, 2008Publication date: October 21, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Dominique Maria Bruls, Johannes Joseph Hubertina Barbara Schleipen, Josephus Arnoldus Henricus Maria Kahlman, Menno Willem Jose Prins
