A method for recycling of laminated glass is disclosed. The laminated glass comprises at least one glass layer and at least one polyvinyl butyral (PVB). The method comprises mechanical removal of at least part of the glass, placing residual waste with glass particles in a vat comprising a separation fluid to produce a mixture of glass particles and one polyvinyl butyral (PVB) pieces from the residual waste, from which the one polyvinyl butyral (PVB) pieces can be screened off, washed, and dried for reuse. The separation fluid comprises water and butyl diglycol.

The present invention relates to systems and methods for characterizing at least one anatomical parameter of an upper airway of a patient by analysing spectral properties of an utterance, comprising: a mechanical coupler comprising means for restricting the jaw position of the patient; means for recording an utterance; and processing means for determining at least one anatomical parameter of the upper airway from the recorded utterance and comparing the recorded utterance to a threshold value. In addition the present invention relates to the use of the above mentioned systems as a diagnostics tool for assessing obstructive sleep apnea.

An emitter system for the irradiation of laminated glass panels of different widths, a glass cutting device for processing laminated glass panels of different widths with such an emitter system, a manufacturing method for such an emitter system, and a use of such an emitter system for the irradiation of laminated glass panels of different widths. The emitter system includes a plurality of elongated emitters. The elongated emitters are arranged one behind the other on a common longitudinal axis. The elongated emitters each have two ends, which are angled in relation to the common longitudinal axis. The emitter system is arranged in a glass cutting device.

A method of field shaping a laminated glass structure is provided. The method includes providing the laminated glass structure comprising a flexible glass sheet having a thickness of no greater than about 0.3 mm laminated to a non-glass substrate by an adhesive material. The laminated glass structure is field cut using a handheld power tool thereby forming a shaped laminated glass structure. An edge strength of a cut edge of the shaped laminated glass structure at least about 20 MPa.

An apparatus for separating a composite safety glass panel along at least one predefinable dividing line, wherein the composite safety glass panel has at least one composite film and at least two glass panels, wherein the composite film is arranged between the glass panels and connects the glass panels to each other, the apparatus having at least one separating means for separating the glass panels along the at least one dividing line and at least one heating means for heating the composite film at least along the dividing line. The invention further relates to a method for separating a composite safety glass panel. A method and an apparatus for separating a composite safety glass panel, wherein the cycle times for separating are shortened, are realized in that the heating means has at least one laser device having at least one plurality of laser radiation sources arranged adjacent to each other, and wherein a plurality of adjacently arranged individual intensity profiles for heating the composite film at least along a portion of the dividing line can be produced by means of the laser device.

A method is disclosed for dividing a composite material in which a brittle material layer and a resin layer are laminated, including: irradiating the resin layer with a laser beam L1 oscillated from a CO.sub.2 laser source along scheduled dividing lines DL of the composite material to form a processing groove along the scheduled dividing lines; and irradiating the brittle material layer with a laser beam L2 oscillated from an ultrashort pulsed laser source along the scheduled dividing lines to form a processing mark along the scheduled dividing lines. In the resin removing step, in a region IS where the scheduled dividing lines intersect, the laser beam oscillated from the CO.sub.2 laser source is not irradiated multiple times, or an irradiation amount of the laser beam is decreased relative to an irradiation amount in a region other than a region where the scheduled dividing lines intersect.

Embodiments of the disclosure relate to a method of preparing a multi-piece laminated article. In the method a first glass ply and a second glass ply are co-sagged. The first glass ply is laser cut to form a first primary piece and a first secondary piece, and the second glass ply is laser cut to form a second primary piece and a second secondary piece. The first primary piece and the second primary piece each define a hole into which the first secondary piece and the second secondary piece, respectively, fit. The first primary piece and the second primary piece are laminated to each other to form a first laminated piece, and the first secondary piece and the second secondary piece are laminated to each other to form a second laminated piece. The method can be used to prepare, for example, automotive glazing.
