Title: Inventor Yvan Greiner: Advancements in Timepiece Measurement
Introduction
Yvan Greiner, located in La Chaux-de-Fonds, Switzerland, is an innovative inventor known for his contributions to the field of precision measurement in timekeeping devices. Holding two patents, Greiner's work primarily focuses on enhancing the accuracy and functionality of timepiece movements.
Latest Patents
One of Greiner's notable patents is a "Device for measuring the operation of a timepiece movement." This device generates measuring pulses in response to vibrations of the movement, allowing for the measurement of time intervals between these vibrations. The operation is finely tuned, enabling pulse generation within a short, predefined window following a blocking period that is contingent on previous time intervals.
His second significant patent, "Method of and apparatus for measuring the amplitude of oscillation of a timepiece movement," introduces a methodology to measure the oscillation amplitude of the balance in timepieces with an escapement mechanism. This invention measures time intervals between disengagement and engagement of the balance, as well as the durations of its vibrations. It operationally counts pulses at two different frequencies, enabling a calculation that reveals the amplitude of oscillation through a predetermined relationship.
