Latest Patents

One of Pernice's latest patents is titled "Planar structure of a mechanical resonator decoupled by bending oscillation and expansion/compression vibrations." This invention addresses the common drawbacks of mechanical resonators used in timepieces, which often lack efficiency, compactness, and affordability. The planar structure he developed reduces bulkiness and manufacturing costs by incorporating a bar that vibrates in longitudinal expansion/compression resonance, along with two beams that vibrate simultaneously in both longitudinal and bending oscillation. This innovative design allows for high-quality factors in resonators by preventing the transmission of transverse deformations to the attachment pads.

Another significant patent is related to an "Element vibrating in two uncoupled modes, and use in vibrating rate gyroscope." This invention involves a vibrating element that is planar and aligned with the electrical crystallographic axis of a piezoelectric material, such as quartz. The design includes a beam with electrodes and a stationary portion connected to one end, while the other end is connected to a solid portion. The unique structure allows for precise measurements of angular speed in rate gyroscopes, enhancing their accuracy.
