Abstract: A mouthpiece system for deterring evasion of an alcohol breath test particularly a test wherein a breath sample is delivered without human supervision. The system includes a mouthpiece configured so as to render difficult the delivery of artificial breath samples through the use of hoses, balloons and the like. The mouthpiece has an oversize upper surface which includes a tapered lip around the mouthpiece inlet to receive the mouth of the user. The lip is surrounded by a wide apertured ring which, together with the lip, will not readily form an effective connection with a balloon or hose. An electrode on the mouthpiece is used for sensing and/or signalling the user. The impedance in contact with the electrode is sensed during testing to insure it falls within a range expected for a human user to deter use of evasion using filters or bogus gas delivery devices. Continuity of the impedance during testing is monitored to detect attempts to pass the mouthpiece to an accomplice.

Abstract: A connector for coupling a hose to a faucet or the like includes two molded plastic members which are coupled together by a bayonet-type connection. One member carries a resilient seal which has an annular lip inclined radially inwardly and axially toward an axially facing annular sealing surface on the other member. When the members are coupled, the lip flattens against the sealing surface to form a seal between the members and, in this condition of the parts, the resiliency of the lip also produces a force which keeps the bayonet-type connection in the locked position. When the members are being coupled while water is running through the member with the seal, an annular groove in the sealing surface causes water to backwash and clean the sealing side of the lip as well as the sealing surface itself.
