An ethanol sensing unit and a method of using, wherein the unit is particularly suitable for use in a confined environment such as the passenger compartment of a passenger vehicle. The sensing unit comprises a device for collecting ethanol vapors while the device is at a first temperature, a device for heating the collecting device to a second temperature higher than the first temperature so as to release ethanol vapors from the collecting device, and a device for sensing the ethanol vapors released from the collecting device when heated by the heating device. The sensing unit is also adapted to delay the operation of the heating device until a period of time sufficient for the collecting device to adsorb ethanol vapors from air contained in the confined environment.

A MR fluid formulation based upon a silicone liquid vehicle thickened with a treated fumed metal oxide and doped with one or more chemicals having hydrogen-bonding capability for use with natural rubber mounts. The MR fluid is resistant to settling of the magnetizable particles upon contact of the fluid with natural rubber. In one exemplary embodiment, the doping chemical is one or a combination of propylene glycol and a bifunctional ethoxylated amine.

To measure the percentage of soot in a diesel engine crankcase oil without any significant influence by oil additives or contaminants which build up in the oil during usage. The relative permittivity of the oil is measured in the microwave region of 8-12 GHz (X band). For soot content up to about five percent, the relative permittivity of the oil is a substantially linear function of the soot content.
