Latest Patents

Gadrault's latest patents include a "Transmitter-receiver system for variable-rate digital data transmission." This innovative system is designed to operate over a broad temperature range and features a large dynamic range. The receiver provides an alternating-current connection between the transimpedance circuit assembly and two comparator circuits, which process a signal coded at three levels. A threshold-generating circuit allows for automatic switching among predetermined discrete values based on the signal's amplitude variation. Additionally, a circuit inhibits overoscillations before transcoding, ensuring smooth data transmission. The transmitter delivers information using an internal code, such as a PBP code, with a constant direct-current component and refreshment.

Another significant patent is the "Multiple-threshold optical receiver for a variable-rate digital data." This optical receiver is designed for alternating-current transmission and operates effectively over a broad temperature range. It includes a capacitor between the transimpedance circuit and two comparator circuits for processing a signal coded at three levels. The amplifier used can have a wide band while excluding the direct-current component. Similar to his previous patent, a threshold-generating circuit allows for automatic connection to predetermined discrete values based on signal amplitude variation. The optical link transmitter delivers coded information in accordance with a constant direct-current component code, such as a PBP code.
