Abstract: A probe for a closed transfer system, the probe including a probe body and a probe tip. The probe body defines an inlet, an outlet, and a plurality of channels. The outlet is in fluid communication with the inlet via at least one of the plurality of channels. The probe tip is located at a top end of the probe body and defines a first passageway. The first passageway is in fluid communication with at least one of the plurality of channels. The probe body is configured to be slidably moveable within a coupler body between a first position where the probe tip is received within the coupler body and a second position where the probe tip extends at least partially away from the coupler body to open a fluid flow path through the coupler body.

Abstract: Provided herein are methodologies, systems, apparatus, and non-transitory computer-readable media for detecting firearm straw purchases and providing approval or denial of an attempted firearm purchase. Address information is collected from anyone attempting to purchase a firearm. This address information is normalized to create a normalized address string, which accounts for misspellings and/or abbreviations in the address information. This normalized address string is compared against normalized addresses associated with people who are prohibited from purchasing a firearm, and a similarity coefficient is calculated. The similarity coefficient is then compared against a threshold value, and if the similarity coefficient is greater than the threshold value, the firearm purchase can be declined. If, however, the similarity coefficient is below the threshold value, the firearm purchase can be approved.
