A method for applying an optical mark to a spectacle lens mounted in a spectacle frame includes determining an intended position of the optical mark at the spectacle lens based on the spectacle frame. The method further includes taking an image of at least a part of the spectacle frame and arranging the spectacle frame in a marking device having a marking appliance and adjusting the relative position of the spectacle frame and the marking appliance such that an actuation axis of the marking appliance intersects with the spectacle lens at the intended position of the optical mark. Additionally, the optical mark to the spectacle lens is applied at the intended position by using the marking appliance. The use of a spectacle frame as a positioning reference for an optical mark and a marking device are also disclosed.

A computer-implemented method for generating data to produce a spectacle lens adapted to a spectacle frame is disclosed. The method includes: (i) providing, on a storage medium, a first data set containing a centering value and a three-dimensional model of the spectacle frame; (ii) creating, using the first data set, a second data set containing a geometric value of a surface of the spectacle lens; (iii) creating, in order to produce the spectacle lens from a spectacle lens blank and to grind in and/or fit the at least one spectacle lens into the spectacle frame using the first and second data sets, a third data set stored on the storage medium, wherein the data values of each data set have a spatial relationship with respect to each other such that the data values of each data set are consistently specified in relation to a particular coordinate system.

Computer-implemented method for generating data in order to produce at least one spectacle lens, and method for producing a pair of spectacles

An apparatus and a method for optical measurement of an internal contour of a spectacle frame are disclosed. The apparatus contains an optical unit, which is configured to capture light reflected from an illuminated section of the inner contour of the spectacle frame. The optical unit is insertable into the inner contour of the spectacle frame and, when inserted as intended, is rotatable relative to the spectacle frame. The optical unit contains at least one light source, an objective, and at least one optical sensor, wherein the light source is configured to generate a light section, wherein at least one section of the inner contour is illuminable by the light section, wherein the objective is configured to image the illuminated section of the inner contour onto the optical sensor, and wherein the optical sensor is configured to capture the light reflected by the illuminated section of the inner contour.

The invention relates to a method and an apparatus for tracking a fundamental frequency of a voice signal. A sampling device samples a voice signal of a test person for a predetermined period of time (S), thus obtaining sampling data of the voice signal, forms a data packet from the sampling data (S), and sends the data packet to a calculating device (S). The calculating device receives the data packet (S) and calculates a fundamental frequency of the voice signal by means of the sampling data contained in the data packet (S). The sampling device sets a timer based on the fundamental frequency calculated by the calculating device and outputs a trigger signal upon expiration of the timer (S).
