Abstract: A system, method, and computer program to implement Public Key Infrastructure (“PKI”)-based access controls on a computing device independently of the operating system's user identification and authorization system. A software application on a standalone, non-networked computing device detects a “smart card” with a PKI certificate identifying the card holder. The identity of the card holder is verified against a registry stored on the computing device separately from the operating system's user identification and authorization system. Verification of the identity of the card holder results in setting the state of the computer system as “authorized” or “unauthorized.” In the unauthorized state, user input and viewing of information is prevented. The software application may thus identify individual smart card holders and provide secure access to data and resources, and track authorized and unauthorized access on computing devices that must remain in an “always logged in” state.

Abstract: This invention relates to a co-tube assembly for a heating and air conditioning system. The co-tube assembly comprises a connector an inner tube and an outer tube. The connector including a first opening, a second opening and a third opening. The inner tube extends through the first opening and the second opening of the connector. The inner tube has a first portion axially outwardly of the first opening of the connector and a second portion axially outwardly of the second opening of the connector. The outer tube is disposed over the first portion of said inner tube and inserted into said first opening of the connector.

Abstract: A one-way flow valve quick connector is used in automotive fuel tank filler systems to interconnect the fuel filler tube with the fuel tank without the use of tools or special equipment. The quick connector includes a check valve to establish a substantially hermetic seal between the tank and the environment at all times to prevent the escape of liquid fuel during the refueling process as well as the escape of toxic vapors. A bypass vent operates during the refueling process to draw any vapors escaping from the tank or entering through the fuel fill tube inlet, filtering and returning them to the fuel tank.
