Latest Patents

Charlton's latest patents include innovative systems and methods for adaptive optical modem configuration based on operating conditions. One of his patents describes a transmitter that communicates over an optical link to a receiver. This system includes a controller that, while operating in a first mode, obtains measurements related to the optical link's operation. It determines statistical properties based on these measurements, which relate to conditions on the optical link. The controller then sets a second operating mode for the transmitter and receiver based on the determined statistical properties. This approach allows for a trade-off between the first and second operating modes, optimizing performance based on real-time conditions.

Another patent focuses on operating an optical modem with first operating settings. In response to detecting or anticipating a disturbance in operating conditions, the modem switches to second operating settings for a specified time period. This method is based on the statistical properties of the disturbance, which can include polarization transients or other factors affecting the system's performance. After the time period, the system reverts to the first operating settings, ensuring optimal functionality.
