Abstract: 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.

Abstract: 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.
