Abstract: Disclosed in a method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation including shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.

Abstract: A method includes the following steps of (i) production with a 3D scanner, of a three-dimensional digital reference model of at least part of a dental arch of the patient, or “initial reference model”; (ii) acquisition, in actual acquisition conditions, by the patient or one of his or her close relatives, with a mobile phone, of at least three two-dimensional images of the dental arches of the patient corresponding to a front view, a right-side view and a left side view of the teeth of the patient, respectively, called “updated images”; and (iii) searching, through modification of the initial reference model, for a final reference model corresponding to the positioning and/or the shape of the teeth on the updated images.

Abstract: A method of making a colorimeter colour standard, including determining print parameters required to achieve a desired colour for the colour standard, printing the desired colour on a colour-receiving face of a first transparent piece using the determined print parameters and permanently affixing the printed first piece to a second transparent piece such that the colour-receiving face of the first transparent piece and a joining face of the second transparent piece are positioned at the interface between the first transparent piece and the second transparent piece.

Abstract: The present disclosure relates to a method for calibrating a projector. In one example, the method includes receiving by a processing element light field data corresponding to a calibration image projected by a projector and captured by a light field capturing device, and modeling by a processing element one or more intrinsic properties of the projector using the light field data and the calibration image. The calibration image may be projected by the projector directly into the light field capturing device.

Abstract: An illumination device comprises one or more emitter modules having improved thermal and electrical characteristics. According to one embodiment, each emitter module comprises a plurality of light emitting diodes (LEDs) configured for producing illumination for the illumination device, one or more photodetectors configured for detecting the illumination produced by the plurality of LEDs, a substrate upon which the plurality of LEDs and the one or more photodetectors are mounted, wherein the substrate is configured to provide a relatively high thermal impedance in the lateral direction, and a relatively low thermal impedance in the vertical direction, and a primary optics structure coupled to the substrate for encapsulating the plurality of LEDs and the one or more photodetectors within the primary optics structure.

Abstract: A method is provided for providing a set of ingredients for manufacturing of a dental prosthesis covering. The method comprises receiving a background colour value providing information on a colour of a background substrate on which the prosthesis is to be provided, receiving an appearance colour value providing information on an appearance colour of the prosthesis and receiving a thickness value providing information on a thickness of the dental prosthesis covering. In an electronic memory, a first ingredient record is looked up comprising first ingredient value, based on the measured background value and the measured appearance colour value. The first ingredient values are adjusted in an electronic processor adjusted based on the thickness value and through electronic output means, the adjusted ingredient data is provided. By adjusting ingredients for thickness, a more natural appearance may be achieved.

Abstract: An image capturing device includes: an illuminator configured to generate illumination light having wavelength bands and an illumination characteristic; an imager configured to generate an image signal by capturing light from a subject; and a processor configured to: control the illumination characteristic; set a piece of statistical data used for estimating a spectral characteristic of the subject included in the image signal; estimate the spectral characteristic of the subject included in the image signal based on the set piece of statistical data; define an illumination characteristic of illumination light in accordance with the estimated spectral characteristic of the subject; and determine whether or not the set piece of statistical data is an adequate piece of statistical data based on whether or not an image signal generated by the imager under the illumination light having the defined illumination characteristic satisfies a criterion for achromatic color.

Abstract: A meter for measuring UV light having wavelengths, preferably between 205 nm and 237 nm. The meter includes at least one UV sensitive photo diode adapted for detecting the wavelengths of UV light between a lower end and an upper end; a first filter that blocks the UV light having wavelengths below 237 nm down to at least the lower end that the UV sensitive photo diode can detect; a second filter that blocks the UV light having wavelengths above 230 nm up to at least 205 nm; at least one amplifier for amplifying a signal from the UV sensitive photo diode; an analog to digital converter; a microprocessor; a battery in electrical communication with the microprocessor. The microprocessor preferably being in communication with the amplifier and the analog to digital converter. The microprocessor provides a result for the UV light that the UV sensitive photo diode is exposed to.
