Abstract: A robotic arm system comprising an artificial intelligence (AI) processor system, a transceiver electrically coupled to the AI processor system, and a robotic arm having an optical data communication network that communicates with the transceiver. The robotic arm further comprises a transmitter, a plurality of sensors electrically coupled to the transmitter, a receiver, and a plurality of motion actuators electrically coupled to the receiver. The optical data communication network comprises gigabit plastic optical fiber (GbPOF) having a graded-index core made of a transparent carbon-hydrogen bond-free perfluorinated polymer with dopant. In one embodiment, one GbPOF optically couples the transmitter to the transceiver and another GbPOF optically couples the transceiver to the receiver. The flexible high-data-rate GbPOF enables robotic arm control using artificial intelligence.

Abstract: A process to enhance the performance of plastic optical fiber to operate with a high data rate (e.g., at least 1 gigabit per second) at high temperature (e.g., 100 degrees Celsius) for airplane avionic systems. Gigabit plastic optical fiber has a core including a dopant that enables data transmission at gigabit rates. The enhancement process uses rapid thermal cooling of the gigabit plastic optical fiber to stabilize the polymer matrix of the fiber. This rapid cooling treatment blocks dopant diffusion in a high-temperature environment, thereby avoiding degradation of the fiber's bandwidth and optical loss characteristic. Such degradation typically occurs in gigabit plastic optical fiber having core and cladding made of transparent carbon-hydrogen bond-free perfluorinated polymer.

Abstract: An apparatus configured to function as a pluggable active optical connector that is modular with one or more channels and that converts electrical signals to optical signals and vice versa. On one side, the apparatus has a pluggable electrical interface to a line replaceable unit (LRU); on the other side the apparatus has a pluggable optical interface side to an aircraft fiber optic wiring bundle. The apparatus is pluggable to different types of LRUs including rack-mounted and bolted-down LRUs. The apparatus includes electronic and photonic components sufficient to enable electrical/optical conversion totally within a standard-sized aircraft connector. The apparatus is adaptable to various data communication protocols and has the flexibility to be used in either a single-fiber or a dual-fiber bidirectional data link.

Abstract: Systems and methods that use a differential spectral liquid level sensor to measure the level of liquid in a reservoir (e.g., a fuel tank or other storage container). The use of a differential spectral liquid level sensor solves the problem of common-mode intensity variations (i.e., intensity variations not due to the level of the liquid) by having two different wavelengths propagate through the same optical path but have different spectral attenuations in the liquid. By determining the ratio of the received optical powers, common-mode intensity variations can be neutralized, thereby enhancing the accuracy of the received power reading and the resulting liquid level indication.
