A compound for protection of an object from a blast or shock wave. The compound include a matrix material and at least a first and second sets of inclusions in the matrix material that differ in size, quantity, shape and/or composition in a direction through the impact-absorbing material, the combination of which contributes to the ability of the material to exhibit at least one property that changes as the inclusions are deformed in response to a blast or shock wave.

Systems and methods for detecting the effects of concussion are disclosed. In various embodiments, fMRI or other live analysis technique captures data regarding the subject's brain activity while he or she is performing a task that exercises one or more particular functional centers. In some embodiments, post-collision activity is compared to baseline data, and the diagnosis operates as a function of the comparison. in other embodiments, post-collision activity is analyzed, such as by partitioning the activity data into regions of interest and calculating activity for one particular region in comparison with certain other, perhaps adjacent, regions.

A noninvasive method of treating or preventing pressure ulcers is disclosed. The method includes placing a motorized pad about a subject, activating a plurality of motors positioned in the motorized pad each having an output shaft to thereby cause application of a rotational motion to each of the plurality of motor shafts, converting the rotational motion to a vibrational motion by using a corresponding unbalanced mass with each motor, applying the vibrational motion to a corresponding part of the subject, and damping any vibrational forces substantially parallel to an underlying skin surface more than vibrational forces substantially perpendicular to the underlying skin surface.
