Abstract: A device to secure a child seat to a vehicle's seat comprises of a piece of webbing to which two fixed pieces are attached, one to each end, and a movable piece that runs freely along the piece of webbing. The device secures the child seat to the bodywork/frame of the vehicle and to the seat, regardless of the vehicle's model.

Abstract: A method of designing a skeletal implant comprises measuring physical characteristics of the bone to be implanted, generating a macro-design of the implant based on the physical characteristics, and determining a micro-design for the implant to ensure that strain in the bone is kept between 100 and 3000 microstrain to promote bone growth and to minimize bone resorption during functional loading. In an alternate embodiment, a dental implant comprises a crest portion having a circular bottom surface, an opposite circular top surface, and a side wall intermediate the bottom surface and the top surface, the top surface being adapted for attaching the dental prosthesis thereto. A circular base portion has a crestal end, an opposite apical end, and a core section intermediate the crestal end and the apical end having an outer surface. A helical thread extends about a portion of the outer surface of the core section that secures the device within existing bone.

Abstract: A dental implant for having a longitudinal axis for implanting in bone, has a crest module having a top end, a bottom end and a wall having an outer surface and a threaded section. The threaded section has a crestal end and an apical end, the crestal end abutting the bottom end of the crest module, a helical thread extending along a portion of the first section from a base end outwardly to a distal end. The threaded section also has a length, a major diameter being defined as the diameter of the threaded section measured at the distal end of the thread and a minor diameter being defined as the diameter of the threaded section measured at the base end of the helical thread. The major diameter is constant along the length of the threaded section, whereas a selected thread feature is chosen as a function of a selected biomedical characteristic. The selected thread feature could include the minor diameter, the thread pitch or the thread geometry.
