An apparatus and / or method that corrects for tuning errors in vibrating structure gyroscopes that are configured to be driven along a plurality of axes without the need for dedicated torque elements. The correction is accomplished by introducing a phase offset in the drive signal of one or more of the drive elements relative to other drive elements to minimize or reduce the quadrature signal. The tuning may be accomplished as a one time “set and forget” adjustment, as a manual adjustment performed at the discretion of the user, or as a closed loop active correction system. The technique improves the tuning of the resonator assembly, rather than merely compensating for the mistuning. Accordingly, for various embodiments of the invention, the destructive interference between the plurality of drive axes is reduced. Conservation of vibrational energy present in the resonator is thus enhanced, with less vibrational energy transferred to the support structure.

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 plasma lamp. The lamp includes a housing having a spatial volume defined within the housing. In a specific embodiment, the spatial volume has an inner region and an outer region. The lamp also has a support region coupled to the inner region of the spatial volume and a support body having an outer surface region slidably inserted and disposed within or partially disposed the support region. In a preferred embodiment, the support body has a support length, a support first end, and a support second end. The plasma lamp has a gas-filled vessel coupled to the support first end of the support body. In a preferred embodiment, the gas filled vessel has a transparent or translucent body, an inner surface and an outer surface, a cavity formed within the inner surface. In a preferred embodiment, the cavity is sealed and includes a fill material, which is capable of discharge. The lamp has an rf source operably coupled to at least the first end of the gas-filled vessel. In a specific embodiment, the rf source is configured to cause a discharge of one or more gases in the gas filled vessel.
