Title: The Innovations of Rose Cordier
Introduction
Rose Cordier is a notable inventor based in Paris, France. She has made significant contributions to the field of optical fiber technology, holding 2 patents that showcase her innovative spirit and technical expertise.
Latest Patents
One of her latest patents is a system for transmitting digital signals over an optical fiber. This invention includes a receiver that comprises a device for restoring each digital signal. It features a first comparator that compares the level of the electric signal with a first reference level, generating a signal when the level of the electric signal is less than the reference level. Additionally, a second comparator compares the level of the electric signal with a second reference level, generating a signal when the level of the electric signal is greater than the reference level. A summator then sums the signals generated by the two comparators. Another significant patent is a device for triggering an alarm system in the event of insufficiency. This alarm-triggering device for the receiver of an optical-fiber transmission system includes a filter with a passband located externally with respect to the band of frequencies employed for optical-fiber transmission. The input of this filter is connected to an avalanche photodiode, followed by an amplifier, a rectifier, a voltage comparator circuit, and an alarm-triggering circuit.
