Latest Patents

Echelard's latest patents include a very high-precision clock module controlled by a reference signal. This clock module features a main precision oscillator that generates a first clock signal of a predetermined frequency. It also includes a receiving module that receives a time reference and provides a time reference signal to control the main oscillator. A detector is integrated to identify any failures in the main oscillator or the time reference signal. This detector comprises a second oscillator that is not controlled by the clock module, delivering a second clock signal of predetermined frequency. The processor within the module measures phase differences between the signals to ensure accuracy.

Another significant patent is for a real-time clock integrated module and device. This device outputs data indicating the time of day and includes a high-precision oscillator or atomic clock with an accuracy of 50 parts per billion or better. The timing circuit generates time-of-day data based on the clock signal and maintains time even when powered off. It updates the timestamp value based on the oscillator or atomic clock, ensuring reliability when the device is powered back on.
