Abstract: Rotational alignment apparatus and methods for interchangeable loupe telescope(s) are provided. Some embodiments include an indexing ring including a projection. The ring is fixed to the telescope upon rotational alignment of the telescope. The alignment may involve use of a laser and test fixture. The projection mates with a corresponding indexing notch of a loupe anchoring device. Loupes may comprise one or more anchor assemblies, and one or more interchangeable telescope assemblies. The interchangeable telescope assemblies are held to the anchor assemblies by magnetic attraction between one or more magnets and/or one or more magnetic components affixed to corresponding surfaces of the corresponding assemblies. Mating of the projection with the notch ensures appropriate relative rotational alignment of the assemblies.

Abstract: A buzzer includes a piezoelectric diaphragm and a housing enclosing the diaphragm and defining a resonating chamber. The chamber includes a sound port and has an optimal resonating frequency fHt at a temperature T defined by fHt=(vt/2?)(?(A/voL)) were vt is the velocity of sound waves in air at a temperature T, A is the effective area of the sound port, vo is the volume of the resonating chamber, and L is the effective length of the sound port. A temperature compensating member moves in response to changes in temperature to change the value of ?(A/voL) at a rate and in a manner that balances the change in 1/vt across that same temperature range, thereby reducing changes in the product (vt/2?)(?(A/voL)) and consequently reducing any changes that would otherwise occur in fHt across that temperature range, thereby holding the value of fH substantially constant across the temperature range.
