The sensor for mandibular movement measurement is a distance sensor which
permits observation of mandibular movements. The signal given by this sensor
is known as Jawac, short for «Jaw Activity».
The monitoring of mandibular movements during sleep not only allows to iden-
tify the different sleep disturbances such as mouth breathing, snoring, apneas
(central, obstructive, and mixed) and hypopneas, but also to detect conditions
of upper airway resistance (UARS).
