A method of cutting a glass sheet is disclosed. The method comprises heating a heating element to a heat temperature, which in turn heats a glass sheet along a desired cutting line, to a separation temperature. The glass sheet is subjected to non-destructive pressure at an edge on the cutting line. The non-destructive pressure may be applied by a tool with opposed sharp edges so long as the edges do not nick or otherwise score the glass sheet. A diagonal cutter may be utilized as the sharp-edged tool. After an adequate amount of heating time, the glass sheet will achieve the separation temperature and spontaneously separate along the heated cutting line.

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.

A cutting system (10; 10; 10) for slabs (50) which comprises: a longitudinal guide (20; 20; 20) comprising a pair of surfaces (23,24; 23,24; 23,24) opposite to each other, of which a lower surface (24; 24; 24) and an opposite upper surface (23; 23; 23); a suction cup (41; 41; 41) coupled to the lower surface (24; 24; 24) of the longitudinal guide (20; 20; 20) suitable to selectively adhere to a slab (50) and defining a contact surface of the longitudinal guide (20; 20; 20) on the slab (50); the longitudinal guide further comprising a pair of rails (231; 231; 231) parallel to each other coupled to the upper surface (23; 23; 23) of the longitudinal guide (20; 20; 20) and suitable for slidably coupling to a scoring slider (30; 30; 30). The rails (231; 231; 231) are arranged on opposite sides with respect to a median plane (A-A) of the suction cup (41; 41; 41) perpendicular to the contact surface thereof.
