Abstract: A method of providing benefits to owners of non-fungible tokens is provided. A minter of a non-fungible token corresponding to a digital asset can encourage or incentivize users of the non-fungible tokens to purchase additional non-fungible tokens, or perform transactions using a non-fungible token to receive benefits.

Abstract: A drift fence camera trap enclosure includes a frame and sheathing mounted on the frame. An opening extends from a first side of the drift fence camera trap enclosure to a second side of the drift camera enclosure. A threshold is located within the opening. A detection unit detects passage of an animal over the threshold. A camera is configured to capture pictures or video of the animal as the animals cross the threshold.

Abstract: An animal detection unit detects cold-blooded animals and small mammals traversing a tunnel or other constricted area. The animal detection unit includes an elevated threshold that extends across a width of the tunnel or other constricted area. A photo emitter generates a light beam. The photo emitter is located at a first end of the elevated threshold. A photoelectric receiver receives the light beam. The photoelectric receiver is located at a second end of the elevated threshold. The light beam is low enough with respect to the elevated threshold that cold-blooded animals and small mammals moving over the elevated threshold are raised in height sufficiently to block the light beam as the cold-blooded animals and small mammals move over the elevated threshold. A camera is mounted on the frame. The camera is aimed and focused to capture visual recordings of the cold-blooded animals and small mammals as they move over the elevated threshold.
