Abstract: A resonant sensor probe assembly includes a substrate formed from one or more dielectric materials and free-standing electrodes coupled with the substrate. The free-standing electrodes are configured to be placed into the fluid and to generate an electric field between the free-standing electrodes. A controller measures an impedance response of the sensor to the fluid between the electrodes to determine an aging effect of the sensor.

Abstract: An apparatus according to the present invention provides a fluid pour spout including a plunger having a variable position for controlling the flow of fluid therethrough. Also provided is a fluid container having a fluid pour spout including a plunger having a variable position for controlling the flow of fluid therethrough, the spout being at least partially integrally formed with the container or removably coupled thereto. A further apparatus according to the present invention is a lid including a fluid pour spout including a plunger having a variable position for controlling the flow of fluid therethrough, the lid being removably coupleable to a fluid container.
