An assembly design for an oscillating resonator-based sensor where an oscillating crystal resonator such as a quartz crystal resonator is rigidly affixed or ‘mounted’ onto a solid substrate in such a fashion that the resonator can either rest flush against the substrate surface or upon a rigid mounting adhesive. Once cured, the mounting adhesive forms a liquid tight seal between the mounted resonator and the substrate such that only the sensing electrode surface will be exposed to fluids applied to the front side of the substrate. The mounted resonator assembly is designed in such a way that it can be interfaced with a fluid delivery system to form a liquid tight chamber or flow cell around the mounted resonator without incurring additional physical impact upon the mounted resonator. The assembled flow cell can in turn be used to direct multiple fluid streams to flow in a laminar manner over the sensing surface of the mounted resonator and by varying the rates of flow for the different laminar flowing fluid streams the total hydraulic pressure exerted on the surface of the mounted resonator can be held constant.

A decorative floor tile including at least one decorative layer and a backing layer having an array of resilient annular projections. Each annular projection includes a concave top surface, an outside wall surface, and an inside wall surface. The inside wall surface defines a central, blind passageway area. When the decorative floor tile is installed over an underlying surface, and pressure is applied to the decorative floor tile, a vacuum is created within the blind passageway and the underlying surface. The vacuum increases the amount of frictional drag between the surface covering and the underlying surface, and thus allows the surface covering to remain in place without the need for an adhesive.
