Abstract: In one embodiment, an apparatus comprises a micromechanical gyroscope and a circuit. The micromechanical gyroscope is configured to be excited in a first mode by a drive signal, and configured to be excited in a second mode by a gyroscopic effect. The circuit is coupled to the micromechanical gyroscope and configured to detect the gyroscopic effect when the micromechanical gyroscope is in the second mode.

Abstract: A system that incorporates the subject disclosure may include, for example, a method for producing an electrical signal from an apparatus comprising an induction coil coupled to a mechanical resonator, wherein the electrical signal has an operating frequency proportional to a mechanical resonating frequency of the mechanical resonator and proportional to a change in a magnetic flux resulting from a change in orientation in the apparatus, detecting with a detection circuit a change in the electrical signal resulting from a change in the magnetic flux caused by the change in orientation in the apparatus, and determining a direction of the apparatus according to the change in the electrical signal. Other embodiments are disclosed.
