    摘要： Multiple thin film bulk acoustic resonators (10, 11) configured in series (10) and parallel (11) within a coplanar waveguide line structure provides a compact ladder filter. The resonators (10, 11) are formed over an opening (28) in a substrate (20) and connected to associated circuitry by one or more transmission lines formed on the substrate (20). The arrangement of the resonators (10, 11) between the ground and signal lines of a coplanar line structure provides a means of minimising the area of the filter. Embedding a ladder filter within the coplanar transmission line structure eliminates the need for wire bonds, thus simplifying fabrication. Embodiments for 2×2, and hither order filters are described.

    摘要： A ladder-type film bulk acoustic resonator (FBAR) filter comprises two series FBARs and two parallel FBARs. Each FBAR has a top electrode, a bottom electrode, and a piezoelectric layer sandwiched between the top and bottom electrodes. The top electrodes of the two series FBARs form part of a signal line of a coplanar waveguide transmission line. The top electrodes of the two series FBARs are connected to associated circuitry. The two series FBARs have a common bottom electrode.

    摘要： Coin validation apparatus having a coin chute including a hard striking surface upon which a coin entering the apparatus is directed. A microphone is positioned to detect acoustic vibrations of the coin after it strikes the striking surface. An output from the microphone is applied to a fast fourier transform device to produce a signal analysis of the coin vibration. A weighbridge measuring apparatus which is made up of a flexible strip of resilient material carried on a support at each end is provided. The coin rolls across the flexible strip to cause a temporary deflection of a center portion of the strip. A strain gauge located at the strip center to produce an electrical signal representative of the deflection. A classifier compares the signal analysis and the strain gauge signal with stored data representative of a set of standard coins, for classifying the coin as a particular coin value.
