Publication number: 20200189154Abstract: 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.Type: ApplicationFiled: February 21, 2020Publication date: June 18, 2020Inventors: Eric Nauman, Anne Dye Zakrajsek, Andrew James Zakrajsek, Steven Forrest Son, Evan Louis Breedlove

Patent number: 9394959Abstract: Dynamic load-absorbing materials suitable for use as cushion-type and armor-type materials, for example, of types that can be incorporated into protective gear, equipment, armor, vehicles, and various other structures, or used for the isolation and dissipation of vibratory loads, such as vibration isolators used to support avionic equipment. The impact-absorbing materials include a matrix material (22) and at least first and second sets of inclusions (which can be either included material or voids) (24) in the matrix material (22) that define a hierarchy of inclusions (24) in the matrix material (22). The inclusions (24) 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 (24) are deformed under load.Type: GrantFiled: March 8, 2014Date of Patent: July 19, 2016Assignee: PURDUE RESEARCH FOUNDATIONInventors: Eric Allen Nauman, Evan Louis Breedlove, Anne Dye Zakrajsek, Eric S. Lynch

Publication number: 20160022536Abstract: 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.Type: ApplicationFiled: October 7, 2015Publication date: January 28, 2016Inventors: Eric A. Nauman, Jonathan M. Childress, Anne Dye Zakrajsek, James A. Isca, Daniel J. Rawson, Andrew J. Zakrajsek

Publication number: 20140316311Abstract: A sleeve that provides mechanical stimulation to the arm to prevent bone density loss. A primary goal of this product is to prevent bone density loss that occurs during extended space travel. For one embodiment, only the predefined frequency specifications had to be met (between 40 Hz and 60 Hz). By meeting these frequencies for a duration of 30 minutes the product will theoretically prevent the loss of bone density. Additionally, clinical trials will need to be conducted before this product can be marketed. The product includes of several mechanical vibrators attached to a sleeve. The vibrators are small unbalanced-mass motors which are similar to those found in cell phones. The motors are encased in dome shaped housings designed to reduce lateral vibrations along the arm. The product is controlled using an Arduino board attached to the sleeve that actuates the motors.Type: ApplicationFiled: July 1, 2014Publication date: October 23, 2014Inventors: Eric A. Nauman, Jonathan M. Childress, Anne Dye Zakrajsek, James A. Isca, Daniel J. Rawson, Andrew J. Zakrajsek
