Abstract: Implementations of sleep aid devices may include an upper portion configured to receive a user's upper teeth, the upper portion including a first upper projection and a second upper projection. Implementations may include a lower portion configured to receive a user's lower teeth coupled to the upper portion, the lower portion including a first lower projection and a second lower projection. A rear surface of the first lower projection may be configured to contact a front surface of the first upper projection. A rear surface of the second lower projection may be configured to contact a front surface of the second upper projection. The sleep aid device may be configured to one of shift forward the user's mandible or increase the user's occlusal clearance.

Abstract: In an aspect, the invention features a ballistic-resistant panel including at least one layer of ballistic material having a phase change material disposed thereon and an outer cover having inner surface that forms a pocket and an outer surface having an inner face and an outer face. The ballistic material has an inner surface and an outer surface and is disposed within the pocket of the outer cover with the ballistic material inner surface adjacent to the outer cover inner face.
