Abstract: A syringe including a barrel having an interior surface defining an interior extending along a longitudinal axis between an open end and a closed end opposite the open end. The closed end has an orifice that opens to a nozzle extending from the closed end. The syringe includes a plunger including a support and a seal attached to the support. The seal defines a selectively variable volume hollow cavity within the interior of the barrel. A receiver extends longitudinally from a connector face of the support. The receiver includes multiple jaws spaced for receiving an injector fastener having an insertion end and a retention land. Each jaw has an elastically deformable arm and a catching surface for engaging a retention land of the injector fastener when the injector fastener is seated between the jaws.

Abstract: A multiple object speed tracking system that can provide data related to the rate of travel of each object in a set of multiple objects as each object is traveling either toward or away from a predetermined point.
