The present invention relates to a method of displaying pressures and forces on a part of the skeleton such as the feet which relate to movements of the human or animal body, especially movements of the lower skeleton, e. The closed loop having two conductive lines and two connection portions is located on the substrate. Mounting the electronic components to stand upright off the motherboard allows air to enter below the components and rise up through the passageway producing an increase in air speed and better convective cooling. A harness is attached to either end of the elongated neck cushion and is routed over the shoulders, under the arms and across the back. The present invention also provides for a syringe safety device which includes a protective sheath having an elastic member in order to propel the protective sheath from a retracted to an extended position.
