An autonomous mining system includes a real-time digital video transmission sub-system configured to obtain video streams from underground, and transfer the video streams to a control center located above ground; and an exploration and maintenance sub-system located underground, and configured to extract a resource and bring the resource to the surface, based exclusively on commands received from the control center through the real-time digital video transmission sub-system.

Autonomous mining system based on real-time digital video communication that uses ethernet and optical technologies

An optical wireless communication receiver includes one or more harvesting solar cells configured to transform light into electrical power; one or more communication solar cells configured to transform light into an electrical signal embedding information; a rechargeable battery configured to store the electrical power generated by the one or more harvesting solar cells; a communication module configured to decode the electrical signal generated by the one or more communication solar cells and extract the information; a first switch configured to connect the one or more harvesting solar cells to the rechargeable battery for a harvesting-first state, and to the communication module for a communication-second state; a second switch configured to connect the one or more communication solar cells to the communication module for a communication-first state, and to the rechargeable battery for a harvesting-second state; and a microprocessor configured to control the first and second switches.

Energy-autonomous optical wireless communication system

A free node to be deployed underwater for omnidirectional energy and data harvesting includes a housing that forms a sealed chamber; a wavelength-changing layer attached to an outside of the housing and configured to receive a first optical signal having a first wavelength range and to emit a second optical signal having a second wavelength range, different from the first wavelength range, wherein the first optical signal includes encoded data; a flexible solar cell wrapped around the housing, the flexible solar cell being configured to receive the second optical signal and generate an electrical signal; an energy storage module located in the chamber and configured to store electrical energy associated with the electrical signal; and a decoder located in the chamber and configured to receive the electrical signal and decode the encoded data. The first wavelength range is ultraviolet light and the second wavelength range is visible or infrared light.
