Abstract: The invention is a method for padding CPAP face and full face masks forehead and nose bridge area to prevent skin irritation, discomfort, indentions, allergies and ulcers. The pad is attached to the forehead part of the CPAP face mask by way of pockets sewn into the body of the pad. The pad protects the forehead area of the wearer as well as the nose bridge by way of a flap of material that fits between the seal of the mask and the wearer's nose bridge area distributing the pressure from the mask seal. Persons with sleep apnea rely on CPAP therapy to prevent the obstruction in order to continue to breathe while sleeping. The CPAP masks appear medical and strange, especially to a new user of the device. By making the CPAP mask more comfortable with soft padding and also preventing marks and sores, it is more likely that the person will continue their therapy and improve their health.

In other embodiments, constriction of the pads moves pads from their second position to their first position, for this same purpose. In other embodiments, pads having both of the aforementioned characteristics are present.

The polymeric film is sufficiently air-permeable to permit air to escape during rapid compression of the pad structure, such as from a high-speed dynamic impact, but nonetheless is water resistant under ordinary conditions. It is desirable that the polymeric film is made from an elastic polymer. The air-permeability can be provided from a series of perforations such that the film's elastic quality tends to contract the perforations thereby impeding the progress of water through them under normal conditions. The energy-absorbing pad can be a semi-rigid viscoelastic foam.

Abstract: Sensing a force and/or a change in motion proximate to an arbitrarily-shaped surface via a conformal sensing element (e.g., a pressure sensor, an accelerometer) disposed on a flexible substrate and having a sufficient mechanical coupling to the surface. The conformality of the sensing element facilitates intimate proximity to the surface to ensure accurate sensing. Examples of arbitrarily-shaped surfaces include body parts of a person (e.g., a head). A processor receiving one or more signals from the sensing element may provide information relating to possible injury to a body part (e.g., head trauma) resulting from sensed forces and/or changes in motion. Such information may be conveyed by one or more output devices that provide indications of possible degrees of injury/trauma. A conformal sensing apparatus may be integrated with a protective garment or accessory, such as a helmet, wherein the conformality of the sensing apparatus also ensures sufficient comfort for the wearer.
