Abstract
Abstract A resonator-driven timepiece is disclosed comprising a high Q electromechanical resonator which is capable of high excursions without Q degradation. Because of the high excursions, the gear driven by the resonator includes large teeth. The gear is preferably annular with the resonator disposed within the internal dimension of the gear. The resonator is preferably piezoelectrically driven.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
42 words
A timepiece motor comprising a generally annular gear having teeth thereon; a resonator disposed at least partially within the internal dimension of the gear; and means carried by the resonator operatively driving the gear in accordance with the frequency of the resonator.
Claim 2
Dependent Claim
42 words
A timepiece motor comprising a generally annular gear having teeth thereon; a resonator disposed at least partially within the internal dimension of the gear; and means carried by the resonator operatively driving the gear in accordance with the frequency of the resonator.
Claim 3
Dependent Claim
18 words
The timepiece motor of claim 1 wherein the resonator defines a plane generally parallel to the annular gear.
Claim 4
Dependent Claim
20 words
The timepiece motor of claim 1 wherein the resonator comprises a plane coincident with the plane of the annular gear.
Claim 5
Dependent Claim
16 words
The timepiece motor of claim 1 wherein the gear teeth are on the internal diameter thereof.
Claim 6
Dependent Claim
20 words
The timepiece motor of claim 1 wherein the teeth define ratchet teeth and the driving means comprises an index finger.
Claim 7
Dependent Claim
69 words
The timepiece motor of claim 5 wherein the resonator comprises oppositely moving parts, the index finger is affixed to one of the moving parts and the driving means further comprises another index finger secured to the other part, the gear being successively rotated by one and then by the other index finger, the driving movement of one of the index fingers corresponding to the return movement of the other.
