Abstract: A portable device may include a housing sized and shaped to enclose: a power source, a wireless communication module including an antenna and associated transceiver circuitry coupled with the antenna to receive and transmit wireless signals, a human-interaction interface, a memory storing computer-readable instructions; and a processor in communication with the power source, the wireless communication module, and the memory. The housing may be sized and shaped to self-stand when placed at a location. The computer-readable instructions, when executed by the processor, may cause the portable device to: scan, using the wireless communication module, for ones of the plurality of wireless nodes within operating range of the wireless communication module, receive, in response to the scan, wireless-node data from responding ones of the plurality of wireless nodes, generate a user-interpretable signal based on the wireless-node data; and output, using the human-interaction interface, the user-interpretable signal.

Abstract: A usage rule specifies a number of tokens to access a vehicle. Authorization of a request to access the vehicle is based on receiving the number of tokens specified by the usage rule. The request is stored to an electronic ledger. Actuation of the vehicle is based on the request being authorized. An allocation rule specifies the number of tokens allocated to each of an entity and the vehicle based on the request. Allocation of tokens to the entity and the vehicle is based on the allocation rule.

Abstract: A system comprises a computer including a processor and a memory. The memory storing instructions executable by the processor to transmit an authentication request to a vehicle computer, receive, from the vehicle computer, a response including data proving that the vehicle computer includes confidential information, wherein the data does not convey the confidential information, determine whether the response is valid based on the authentication request, and transmit a warning to the vehicle computer when the response is not valid.

Abstract: Systems, methods, and computer-readable media are disclosed for simulations of vehicle-based item delivery. In some examples, a method can include generating a simulation of at least a portion of an environment in which items are to be delivered by a delivery vehicle; determining delivery locations associated with at least one delivery route for the delivery vehicle in the environment within the simulation; determining delivery location groups for the delivery location based on a delivery range of drones associated with the delivery vehicles; and determining waypoints for the delivery vehicle on the delivery route based on a minimum travel time associated with at least one drone of the drones.

Abstract: A system is disclosed that performs multi-factor authentication with respect to a hardware assembly. In one example, a method includes: storing a cryptographic identifier of a vehicle hardware assembly; transmitting, to the assembly, a validation message; receiving a response message; decrypting the response message using the identifier; and determining whether the assembly is authenticated.

Abstract: A vehicle includes a controller, programmed to responsive to detecting a parking space via a camera, generate a parking message including location information about the parking space; broadcast the parking message to fleet vehicles within a predefined geo-fence, each of the fleet vehicles serving as a node of a blockchain network; and receive a predefined reward, via the blockchain network, from one of the fleet vehicles having successfully occupied the parking space.

Abstract: Systems, methods, and computer-readable media are disclosed for vehicle sharing on peer-to-peer networks. Example methods may include determining, by one or more computer processors coupled to at least one memory an input indicative of an environment context of a user, an input indicative of a user request associated with a vehicle. The example methods further include determining a vehicle option or a service option based on the input, accessing a file associated with transactions on a peer-to-peer network including computing nodes connected based on a blockchain protocol, and adding information associated with the user the vehicle option or service option to the file.
