Abstract: A protective headgear having multiple functional layers or functional cells. The protective headgear may have various layers or cells to prevent penetration, absorb energy, and provide chemically-activated cooling in response to an impact. The protective headgear may also have a separate outer shell. The protective headgear may further have sensors for detecting impact levels to the headgear. The sensors may be operatively connected to actuating devices within the headgear for actuating the chemically-activated cooling in response to an impact. The sensor may also be operatively connected to a wireless transmitter device for conveying impact data to a remote monitoring device.

Abstract: Apparatus and methods for full-mouth intraoral image acquisition. An intraoral sensor configuration includes a multi-aperture digital camera and/or a conformal layered sensor structure, a bite piece, and an electronic cable for imaging inside surfaces of a mouth of a patient without having to re-position the digital camera and/or the conformal layered sensor structure within the mouth of the patient during an image acquisition session. Images may be acquired sequentially or simultaneously.
