A nose equalizing device of an underwater mask is provided. The nose equalizing device includes two pouches, each having an opening and a bottom portion corresponding to the opening. Each of the bottom portions is preformed into a first shape having a plurality of continuous folding portions and is in a first position distal from a nose wing of a user. When two fingers of the user exert forces inwardly toward the bottom portions from the openings of the two pouches, respectively, each of the bottom portions is capable of being stretched and deformed into a second shape and being in a second position proximal to the respective nose wing of the user. When the exerted forces are released, each of the bottom portions is capable of automatically or by a reverse force outwards, returning to the first position and restoring to the first shape.

A diving helmet apparatus includes a diving helmet that is based on a 98.sup.th percentile anthropomorphic head form. The helmet is relatively smaller and lighter than convention diving helmets. The center-of-gravity and center-of-buoyancy of the helmet are co-located to reduce diver fatigue. The apparatus has unique neck dam latch devices that use cam mechanisms. The neck dam and the opening in the helmet that receives the diver's head both have a substantially oval shape that contributes to a significant reduction in the volume of the helmet. The apparatus also uses unique face mask latch devices. The neck dam and face mask latch devices allow a diver to easily secure and remove the helmet and face mask without the assistance of dive tenders.

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that when applied to living tissue or similar surfaces displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

An accessory mount for goggles is disclosed which may be attached to the strap or straps of goggles worn on the face of a person. The accessory mount may include a body and a mounting structure. The body may include one or two slits through which the strap or straps of the goggles may be inserted. The body may also include a facial section contoured to fit a person's face, and the facial section may have a cushion configured to rest against the face. The mounting structure may be configured so that different types of accessories, such as a camera or flashlight, may be removably affixed to the mounting structure.
