Latest Patents

One of his latest patents is an opto-electronic transducer device designed for optical link termination equipment. This innovative device includes a method for allocating time slots for transmission in a half-duplex time division multiple access point-to-multipoint bidirectional transmission system. In this method, at least one time slot is allocated to each remote station and to each transmission direction. The time slots used for transmission from the central station to the remote stations are organized into downward frames, while those used for transmission from the remote stations to the central station are grouped into upward frames. The origin time of the upward frame is strategically chosen in each remote station to ensure that it is separated from the end time of downward frames by a period less than twice the transmission time between the remote station and the central station. This design creates an overlap area between upward and downward frames, allowing for efficient communication. The allocation of time slots is carefully managed to prevent any coincidence between time slots assigned to the same remote station in the upward and downward frames within the overlap area.
