Latest Patents

One of Riggins' latest patents is the "Automatic repeat request network transport system for turbulent free-space optical communications links." This invention features a free-space optical (FSO) retransmission device that includes a memory bank partitioned into a source buffer indexed by segment identifications (IDs). The device is designed to communicate with an optical terminal and an Ethernet network, utilizing a programmable circuit to execute various data processing operations. These operations involve receiving data from the Ethernet network, generating an FSO segment, and transmitting an outgoing FSO frame to the optical terminal while storing the outgoing FSO segment until an acknowledgment is received.

Another notable patent is the "High speed error detector for fading propagation channels." This invention is a customized bit error rate tester that characterizes data transmission through a free-space optical channel. It overcomes the limitations of commercial bit error rate testers by providing insights into packet-based channel capacity through bit-level statistics. This allows for the measurement of fade characteristics and the development of a relationship between fade time and data packet lengths, with analog outputs providing real-time data link statistics.
