Abstract: A system includes one or more vessels. Each of the vessels includes a scented medium between a first opening and a second opening. A first valve is disposed at the first opening of each of the one or more vessel. A second valve is disposed at the second opening of each of the one or more vessels. At least one of the first valve or the second valve of one of the one or more vessels is part of a first electromechanical actuation subsystem and another of the first valve or the second valve is a passive valve or is part of a second electromechanical actuation subsystem. A controller controls release of scented gas from at least one of the one or more vessels via the second opening to a corresponding outlet.

Abstract: The present application is directed to a system for verifying calibration of a temperature sensor comprising an above-ambient temperature verifier and a below-ambient temperature verifier. The above-ambient temperature verifier includes a first housing containing an ohmic material. At least one pair of electrodes is provided to direct an applied current through the ohmic material to heat the material. A well is provided within the ohmic material for accepting a temperature sensor. A compression assembly cooperates with the ohmic material to create intimate contact with the temperature sensor. An above-ambient reference temperature monitor maintains a calibrated temperature within the ohmic material. The below-ambient temperature verifier includes a second housing and a below-ambient reference temperature monitor to maintain a calibrated temperature of a below-ambient temperature medium.

Abstract: A liquid heating system includes an electric current controller, a first container, and a second container. The first container includes a first liquid and a first electric heating system. The second container includes a second liquid and a second electric heating system. The electric current controller is connected to the first electric heating system and to the second electric heating system. The electric current controller is configured to automatically alternate between providing electric current to the first electric heating system and to the second electric heating system such that when the electric current controller is providing the current to the first electric heating system the electric current controller provides no electric current to the second electric heating system and when the electric current controller is providing the current to the second electric heating system the electric current controller provides no electric current to the first electric heating system.
