Abstract: An approach is disclosed that receives, at a computer system, a set of biometric data readings pertaining to a user of the system. The biometric data readings are received from biometric sensors that are near the user. After receiving the biometric readings, an audible notification is transmitted to the user. Subsequently, a second set of biometric data readings pertaining to the user from the biometric sensors that are proximate to the user. The first and second sets of biometric data readings are compared with the comparison resulting in a confidence level that the user heard the transmitted audible notification. The audible notification is retransmitted in response to the confidence level being below a threshold not retransmitted in response to the confidence level meeting the threshold indicating that the user heard the first transmission.

Abstract: A seal for a flange includes two separate sealing lips to seal the interfaces between the flange and the intake manifold and the cylinder head. One lip seals against the head surface when the flange is bolted to the cylinder head. The other lip seals around the intake manifold when the intake manifold, such as a tubular intake manifold, is inserted into the flange. The flange seal is made of elastomeric material, such as rubber, and is integrally bonded to the flange made of metal, such as steel or aluminum, during the molding process to form a flange seal having a one-piece construction. The flange seal also includes a gap between one of the sealing lips and an outer surface of the flange that provides a space for the displaced rubber to flow when compressed by the cylinder head. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
