Patent number: 10379028Abstract: The invention describes a laser sensor module (100) which is adapted to detect or determine at least two different physical parameters by means of self-mixing interference by focusing a laser beam to different positions. Such a laser sensor module (100) may be used as an integrated sensor module, for example, in mobile devices (250). The laser sensor module (100) may be used as an input device and in addition as a sensor for detecting physical parameters in an environment of the mobile communication device (250). One physical parameter in the environment of the mobile communication device (250) may, for example, be the concentration of particles in the air (air pollution, smog . . . ). The invention further describes a related method and computer program product.Type: GrantFiled: July 15, 2016Date of Patent: August 13, 2019Assignee: PHILIPS PHOTONICS GMBHInventors: Johannes Hendrikus Maria Spruit, Alexander Marc Van Der Lee, Gerben Kooijman, Okke Ouweltjes, Joachim Wilhelm Hellmig, Arnoldus Johannes Martinus Jozeph Ras, Petrus Theodorus Jutte

Patent number: 10365197Abstract: An optical particle sensor has at least first and second threshold settings applied to an optical sensor or a sensor signal to obtain first and second optical sensor readings. The first and second optical sensor readings are processed to determine a parameter which is dependent on a type of pollution event. The parameter is used to determine from at least one of the first and second optical sensor readings a mass of all particles below a first particle size. In this way the mass of all particles below a desired size can be evaluated, even though the optical sensor may not be responsive to the smallest particles.Type: GrantFiled: June 6, 2016Date of Patent: July 30, 2019Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Michiel Johannes Jongerius, Gerben Kooijman, Koray Karakaya, Okke Ouweltjes

Patent number: 9918814Abstract: An apparatus (100, 100?) is configured such that passage of a fluid (30) through an open port of a distal tip (112, 112?) enables detection of a substance (116) that may be present on a surface (31, 33), e.g., a surface of a tooth, based on measurement of a signal correlating to a substance at least partially obstructing the passage of fluid (30) through the open port. The apparatus (100, 100?) includes a proximal pump portion (124) and at least one distal probe portion (110) configured to be immersed in another fluid (11), e.g., water in toothpaste foam. A corresponding system (3000) includes one or two such apparatuses (3100, 3200). A method of detecting the presence of a substance on a surface includes probing an interaction zone (17) for at least partial obstruction of flow of the second fluid medium (30) through a distal probe tip.Type: GrantFiled: December 20, 2013Date of Patent: March 20, 2018Assignee: KONINKLIJKE PHILIPS N.VInventors: Menno Willem Jose Prins, Johannes Hendrikus Maria Spruit, Petrus Theodorus Jutte, Mark Thomas Johnson, Olaf Thomas Johan Antonie Vermeulen, Okke Ouweltjes, Adrianus Wilhelmus Dionisius Maria Van Den Bijgaart, Martin John Edwards, Steven Charles Deane, Edgar Martinus Van Gool

Patent number: 9765516Abstract: A room divider (100) for dividing a room into two sub-portions (R1, R2) and for attenuating sound (S1, S2) travelling between the two sub-portions is provided. The room divider comprises hollow cylindrical elements (110) arranged periodically for dividing the room into the two sub-portions. At least some of the hollow cylindrical elements have a cylindrical shell (111) with at least one slit (112) extending in an axial direction (120) of the shell. The shell extends continuously along the perimeter of the corresponding hollow cylindrical element from one side (113) of the at least one slit to another side (114) of the at least one slit. Each of the at least one slit faces in a local elongation direction (130) of the room divider for increasing acoustic symmetry with respect to the two sub-portions. The use of destructive interference and resonance to attenuate sound allows for a less bulky/heavy acoustically absorbing room divider.Type: GrantFiled: November 11, 2014Date of Patent: September 19, 2017Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: Cornelus Hendricus Bertus Arnoldus Van Dinther, Ronaldus Maria Aarts, Gerben Kooijman, Okke Ouweltjes, Armin Gerhard Kohlrausch, Hendrikus Hubertus Petrus Gommans, Jasper Van Dorp Schuitman

Patent number: 9750589Abstract: An apparatus is configured such that passage of a fluid through an open port of a distal probe tip enables detection of a substance that may be present on a surface, e.g., a surface of a tooth, based on measurement of a signal correlating to a substance at least partially obstructing the passage of fluid through the open port. The apparatus includes a proximal pump portion and at least one distal probe portion configured to be immersed in another fluid, e.g., water in toothpaste foam. A corresponding system includes one or two such apparatuses. A method of detecting the presence of a substance on a surface includes probing an interaction zone for at least partial obstruction of flow of the fluid through the distal probe tip. The distal probe tip may have a structural configuration for preventing blocking of the open port. The distal probe tip may also have a non-uniform wear profile. The at least one distal probe portion may include two or multiple components to improve performance and reliability.Type: GrantFiled: December 20, 2013Date of Patent: September 5, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Johannes Hendrikus Maria Spruit, Mark Thomas Johnson, Menno Willem Jose Prins, Okke Ouweltjes, Steven Charles Deane, Edgar Martinus Van Gool

Publication number: 20160338635Abstract: A proximal body portion (210) of a detection apparatus for detecting the presence of a substance on a surface includes pump portion (124, 142) and a proximal probe portion (111, 120) in fluid communication with one another. A controller (225) processes signal readings sensed by the parameter sensor (P, P1 or P2) and determines whether the signal readings are indicative of a substance (116) obstructing the passage of fluid (130) through the open port of the distal tip (112, 112?) of a distal probe portion (110) of the detection apparatus (100, 100?, 100?, 100?a, 100?b, 100?c, 100?d, 100c). The controller (225) transmits a signal that changes dynamic pressure at the distal tip (112, 112?) upon determining that the signal readings are indicative of a substance (116) obstructing the passage of fluid (130) through the open port of the distal tip (112, 112?).Type: ApplicationFiled: January 21, 2015Publication date: November 24, 2016Inventors: MARK THOMAS JOHNSON, JOHANNES HENDRIKUS MARIA SPRUIT, MENNO WILLEM JOSE PRINS, STEVEN CHARLES DEANE, PIETER HORSTMAN, EDGAR MARTINUS VAN GOOL, OKKE OUWELTJES

Patent number: 9351071Abstract: An apparatus for determining a position estimate for an audio source comprises two microphones (M1, M2) and an acoustic element (203) providing an acoustic effect to sound from sound source positions to the first microphone (M1). The acoustic effect is asymmetric with respect to an axis (201) between the microphones (M1, M2). A position circuit (305) estimates two possible positions on different sides of the axis for the sound source in response to time of arrivals at the microphones (M1, M2). An estimator (307) determines an acoustic effect measure being indicative of a degree to which an acoustic effect of the first microphone signal matches an expected characteristic of the acoustic effect for sound sources on one side of the axis (201). Another circuit (309) determines the position estimate by selecting between the two possible positions in response to the acoustic effect measure.Type: GrantFiled: January 8, 2013Date of Patent: May 24, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Patrick Kechichian, Okke Ouweltjes
