Abstract: A dental crown and method of use thereof. According to the method provided herein, a dental crown is selected having an appropriate size and shape and an internal contour. The tooth to which the crown is to be applied is prepared to have an external contour. Composite material is injected into the internal contour of the dental crown. The dental crown is placed over the prepared tooth and the deposited composite material is cured using light.

Abstract: A one-piece, hollow, continuous wall pallet having a deck and underside structural features that function in conjunction with the deck for support and reinforcement when a load is placed on the pallet or when a side of the pallet is impacted. The structural features may include an arched bottom recess, side impact depressions, and kiss-off structures, in one of the legs or portion of the underside. The pallet deck may have a dual entry rib configuration. The pallet is preferably made using rotational molding.

Abstract: Related systems and methods are described for determining the angular direction of an atomic beam relative to the beam's reference axis. For a non-relativistic atomic beam, a pair of counterpropagating, equal frequency laser beams intersect the atomic beam at a known angle to the reference axis, preferably perpendicular. The atomic beam direction is inferred from the frequency difference between resonant peaks in the laser beam fluorescence as the laser frequency is scanned. For a relativistic atomic beam, a pair of laser beams intersect the atomic beam from different sides at equal predetermined angles. The atomic beam direction is determined by observing the difference between resonant absorption peaks in the transmitted laser beam intensities as either the laser beam frequencies or laser beam angles relative to the atomic beam are varied. The angles between the laser and atomic beams are preferably selected to minimize the widths of the resonant peaks.
