Abstract: A modular multi-zone mattress and related method of design for which a plurality of mattress modules are adjoined to define a sleep surface having a variable deformability. A number of the mattress modules and a deformability of each mattress module are tailored to a unique body shape and weight distribution of a mattress user to provide at least one of an optimized body posture and an optimized contact pressure distribution over the sleep surface. Pressure factors include a weight and a morphologic profile of the mattress user, and optionally, a sleep position of the mattress user.

Abstract: A helmet having an outer shell defining a convex outer surface and an opposite concave inner surface circumscribing an inner cavity to receive the wearer's head is provided. The helmet has an inner liner connected to the outer shell and located in the inner cavity, where the inner liner contacts the wearer's head when the helmet is worn. The inner liner includes a padding arrangement including a plurality of padding substructures disposed at selected locations in the inner cavity, where at least one of the plurality of paddings has a shear resistance along a shear direction lower than a compressive resistance along a compressive direction, where the compressive direction extends transversally to the shear direction. The helmet also has an attachment device for securing it on the wearer's head.

Abstract: A dental prosthesis system and a method of using same having a prosthesis, a primary bar, and a base-plate. The primary bar is adapted to be received on the implants and to be used as a superstructure for supporting the prosthesis and/or a verification jig. The base-plate has a shape adapted to be received on the patient's gum surface, having at least one hole each in alignment with a corresponding one of the aperture of the primary bar when the primary bar is seated on the base-plate, each hole of the base-plate correspond to the position of each implant hole, the base-plate supporting the primary bar to form a drilling guide for guiding the drilling of implants holes in the patient's jawbone, an impression matrix for creating a physical model of the patient's mouth with implants, and/or a superstructure when removable cylinders are attached to the primary bar.
