    • A resonator assembly comprises a rigid support and a rigid crystal which are rigidly connected along linear segments which have one or more matched thermal characteristics. In a particular embodiment, a thermally matched resonator assembly comprises a Z-cut quartz crystal support, a quartz crystal resonator having an active region and including a crystalline structure oriented relative to X-, Y- and Z-crystallographic axes, which X- and Y-crystallographic axes define an X-Y crystallographic plane; and a rigid connector structure for rigidly connecting the resonator to the support along a segment of a line of a plane parallel to or including the X-Y crystallographic plane, which segment extends across a surface of the resonator and is spaced from the center of the active region of the resonator. A method of mounting a crystal which has the aforementioned crystalline structure to a Z-cut quartz support comprises: selecting a chord on a face of the crystal, which chord is a segment of a line of an X-Y plane intersecting the face of the crystal away from the center of an active region of the crystal; and bonding the crystal of the Z-cut quartz support along the length of the chord.

    • A double resonator beam force transducer configured to minimize longitudinal pumping by making the beams vibrate symmetrically. This can be accomplished by making the boundary conditions of the beams symmetrical or, if the boundary conditions are nonsymmetric, then by biasing the beams inwardly or outwardly to compensate for the nonsymmetrical boundary conditions of the beams. In the nonsymmetrical case where the beams would bow outwardly at their fundamental resonant frequency or an odd overtone thereof, an inward bias is provided to minimize longitudinal pumping. In the nonsymmetrical case where the beams would bow inwardly at an even overtone of the fundamental resonant frequency, an outward bias is provided to minimize longitudinal pumping. The inward or outward bias is provided in various embodiments by bowing the beams inwardly or outwardly, placing masses on the inner or outer edges of the beams, or tapering the inner or outer edges of the beams so that the width of the beams increase toward their midpoints.
