Abstract: Mandibular repositioning devices have a mandibular piece having a first teeth covering and having a housing proximate each of a left molar portion and a right molar portion, a protrusive flange extending cranially from each housing, and a maxillary piece having a second teeth covering and having a housing proximate each of a left molar portion and a right molar portion. Each housing encloses a power source electrically connected an on-board circuit board and the housings of the maxillary piece further have the power source electrically connected to a motor operatively connected to a drive for anterior and posterior movements of the mandibular piece. The maxillary piece sits on the mandibular piece with the driver operatively engaged with the protrusive flange. The protrusive flange has a concavely-shaped anterior surface mated to a convexly-shaped head of the driver shaped to match the concavely-shaped anterior surface of the protrusive flange.

Abstract: A chest non-invasive blood pressure detecting probe based on pulse wave transit time and a device thereof are provided. The detecting probe is attached closely to the skin surface of the human chest, and includes a probe body and a patch, which are of split type. The patch is attached and mounted, in a male-female fastener form, on the probe body for use, so that when the patch needs to be replaced, the patch is directly removed and replaced with a new patch, which is convenient for use. The detecting probe is portable and used for continuous dynamic real-time acquiring of the human aortic blood pressure, which is free from the constraints of lead wires, small and comfortable, and high in measuring precision.

Abstract: A system includes piezoelectric nanofibers, an encapsulation polymer, and patterned electrodes in an array. The array structure of the electrodes can create separate piezoelectric sensor elements, which can detect pressure from pressure such as arterial pulse waves. The sensors arrays can be used to detect the pulse wave velocity of the arterial pulse while it is superficial to near-surface arteries. This can enable detection of blood pressure in a wireless manner.
