Abstract: An anonymous, decentralized, high speed, open source, data-only, wireless network is deployed in physical space. A server attached to the network generates a Non-Fungible Token (NFT) and associates the NFT with a first network device (e.g., a cellular antennae) before the first network device is deployed in the cellular network. After deployment of the first network device into the cellular network, a second network device (e.g., a network validator) can identify the first network device with information from the NFT. In this way, a digital token can identify a physical piece of hardware for communications within the cellular network.

Abstract: A window screen apparatus employing electrostatic principles to purify air. The window screen mesh wires encompass electrically-conductive filaments that are charged by a high-voltage DC pulse generator. Between and surrounding the wires an electric field is created that charges, traps, and repels airborne particulate. An alternative embodiment consists of a window screen in which the screen mesh wires are manufactured from permanently electrostatically charged fibers.
