Abstract: The boresight is comprised of a caliber rod having extending therefrom a reflecting member. The reflecting member has at least one reflecting surface; the reflecting surface being in either a fixed substantially perpendicular orientation to a longitudinal axis through the rod, or able to be adjusted to any desired angle with the axis of the rod. The rod is adapted to be removably slidable, and rotatable, within a muzzle of a bore of a weapon, while it is also constructed to fit snugly within the bore. The boresight may also comprise a beam splitter mirror for gathering light into the aiming device of the weapon. The muzzle of the weapon and the aiming device of the weapon are aligned when the aiming device or reticle (cross-hairs) of the aiming device and the reflection of the aiming device or reticle of the aiming device seen on the reflecting member coincide.

Abstract: A dispensable, disposable shield for stethoscopes prevents the transfer of disease or other contaminants through the incorporation of a disc of plastic film material having a defined edge surface, a pull-tab along the edge surface of the disc, and an adhesive backing on the plastic film material disc, with the plastic film material disc having a contour for covering a diaphragm of the stethoscope and with the adhesive backing covering the entire contour of the disc and being peelably detachable from the stethoscope diaphragm after use. In a second embodiment, the pull-tab is replaced by a flap.
