Patent number: 11399926Abstract: The invention relates to a mouthpiece for performing a treatment of teeth such as teeth whitening. Accordingly, the mouthpiece may be arranged for cosmetic treatment. The treatment is based on illumination of the teeth of light with a suitable wavelength. The mouthpiece is designed so that light from light sources, e.g. LED's, is sufficiently homogenized so that the light irradiance at the teeth is sufficiently uniform to achieve good treatment results. Furthermore, the mouthpiece is designed so that the irradiance at the teeth is sufficiently high to achieve efficient treatment and so that heating of the teeth is minimized to an acceptable heating.Type: GrantFiled: September 6, 2018Date of Patent: August 2, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Nigel David Young, Gertrude Riëtte Bakker-Van Der Kamp, Paulus Cornelis Duineveld, Olaf Thomas Johan Antonie Vermeulen, Valentina Lavezzo, James Donald Gwyer, Zeynep Sabah

Patent number: 11284981Abstract: A smart lighting system for applying light to teeth in the context of tooth whitening and teeth that have been provided with a light-curable whitening varnish. The system includes a light-generating unit, a light-patterning unit, a mouth imaging unit, a mouth image sensing unit, and an image processing and control unit, and is adapted so as to allow the image processing and control unit to adjust the light-patterning unit on the basis of information obtained from the mouth image sensing unit. By doing so, prior to allowing the light-generating unit to emit light, it can be ensured that light emitted to assist tooth whitening, does not affect soft tissue.Type: GrantFiled: October 2, 2015Date of Patent: March 29, 2022Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Nigel David Young

Patent number: 10758330Abstract: The invention relates to a mouthpiece (100) for illumination of teeth, e.g. for teeth whitening. The mouthpiece comprises a slab shaped light guide (203), at least one light source arranged for injecting light into the light guide and an optically transparent element (101) arranged to contact the light guide. The optically transparent element has a lower refractive index than the light guide to enable total internal refection of the injected light. Light is coupled out of the light guide by an out-coupling structure (210) and through a part of the optically transparent part located between the light guide and the buccal side of the teeth to illuminated the teeth with uniform light.Type: GrantFiled: March 20, 2018Date of Patent: September 1, 2020Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Olaf Thomas Johan Antonie Vermeulen, Nigel David Young, Pascal Jean Henri Bloemen

Publication number: 20200146435Abstract: A method (800) for adjusting a user's oral care routine by an oral care device (10) based on interproximal spacing, the method including the steps of: (i) obtaining (820), using the oral care device, information about an interproximal space (66) in the user's mouth; and (ii) automatically adjusting (850), based on the obtained information, a parameter of the oral care device, wherein the dynamic adjustment is configured to improve oral care of the interproximal space.Type: ApplicationFiled: June 14, 2018Publication date: May 14, 2020Inventors: Amir Hussein RMAILE, Steven Charles DEANE, Nigel David YOUNG

Publication number: 20200085554Abstract: The invention relates to an oral care device for teeth whitening or other purpose. The device is designed to provide a uniform light intensity distribution at the teeth by use of a light mixing chamber of a mouthpiece comprised by the oral care device. The mouthpiece comprises a sealing structure with rims designed to connect to the gums of a user. At least apart of the rim and a closure of the mouthpiece surrounded by the rim are reflective. When light is emitted into the mouthpiece, the light will be reflected by the reflective rim, the reflective closure and the buccal side of the teeth. Accordingly, the light will be reflected multiple times, which makes the intensity distribution more uniform. Additionally, the mouthpiece may comprise light redirection structures arranged to redirect light rays from light injected into the mouthpiece.Type: ApplicationFiled: December 28, 2017Publication date: March 19, 2020Inventors: OLAF THOMAS JOHAN ANTONIE VERMEULEN, NIGEL DAVID YOUNG, PASCAL JEAN HENRI BLOEMEN

Patent number: 9700393Abstract: A delivery device (12, 140) includes a source (16) of pressurized fluid and a nozzle (24) which defines an outlet (22). A fluid pathway (20) fluidly connects the source of pressurized fluid with the nozzle outlet (22) for delivery of a spray of fluid from the nozzle outlet. A delivery mechanism (14) releases a dose (48) of particles (28) into the fluid pathway from an associated cartridge (32), such that the dose of the particles is carried by the pressurized fluid through the nozzle outlet in the spray. The particles include a dental care agent.Type: GrantFiled: December 20, 2012Date of Patent: July 11, 2017Assignee: KONINKLIJKE PHILIPS N.V.Inventors: David Andrew Fish, Nigel David Young

Patent number: 9468393Abstract: The appliance includes a brushhead having conductive fiber bristles by which a potential is applied to electrochemically activate a teeth whitening substance, such as peroxide, in the vicinity of the teeth. An impedance appliance system (62) or an optical appliance system (27) provides information concerning whether the conductive fiber bristles are adjacent a tooth surface or gum region. The impedance system uses an electrical signal through the fiber to determine the impedance of a circuit which includes the tooth or gum surface, the impedance being different, depending on whether a tooth or gum surface is in the circuit. The optical system generates a light beam which is directed to the mouth surface through a conductive fiber, the color of the returning light indicating whether the surface is a tooth or gum region. If a tooth is determined, the teeth whitening substance is activated at that bristle, while if gum tissue is determined, the teeth whitening substance is not activated at that bristle.Type: GrantFiled: June 30, 2014Date of Patent: October 18, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: David Andrew Fish, Nigel David Young, Jay Patel, Estelle Julie Dorothee Bernhard-Fichet, Peter Douglas Fairley

Patent number: 8581212Abstract: The monitoring of UV radiation has received increased attention recently due to the hazards of accelerated skin ageing and even cancer following excessive exposure. Personalized monitoring gives a more accurate reading than crude weather forecasts of the ‘UV index’. This invention answers both these needs in a personal UV monitor that is incorporated into an existing display. Minimal processing changes are made to an existing display in order to achieve this added functionality, which is therefore achieved at little additional cost.Type: GrantFiled: December 22, 2009Date of Patent: November 12, 2013Assignee: Chimei Innolux CorporationInventors: Nigel David Young, Peter Fairley

Patent number: 8399855Abstract: A photodiode (200), for instance a PN or a PIN photodiode, is disclosed. The photodiode receives incident radiation having first and second spectral distributions, where the first spectral distribution is spectrally shifted from the second spectral distribution. The photodiode has a first semiconductor layer (211) capable of absorbing incident radiation (231) having a first spectral distribution without generating a photocurrent, while simultaneously transmitting incident radiation having a second spectral distribution to the intrinsic layer (212) for generating a photocurrent (213). The photodiode may be used in connection with detecting the presence of target molecules that has been labeled with labeling agents, such as fluorophores or quantum dots. The labeling agents are characterized by the Stokes shift and, therefore, they emit fluorescent radiation having the second spectral distribution that is spectrally shifted from the illumination radiation having the first spectral distribution.Type: GrantFiled: July 5, 2007Date of Patent: March 19, 2013Assignee: Koninklijke Philips Electronics N.V.Inventors: Pieter Jan Van Der Zaag, Ian French, Nigel David Young

Patent number: 8076857Abstract: A display device comprises an illumination source (12), a display modulator (10) for modulating the light provided by the illumination source and an integrated light sensor arrangement (14) to detect a light level. Light sensor signals from a plurality of light sensors are processed such that localized shielding of the ambient light at the location of one or more of the light sensors is identified. An accurate estimate of the ambient light level can then be obtained.Type: GrantFiled: September 24, 2008Date of Patent: December 13, 2011Assignee: Chimei Innolux CorporationInventor: Nigel David Young
