Abstract: A marking maintenance system comprising a marking database, a drone, and a data network communicatively coupled to the marking database and drone. The marking database is arranged to store marking data associated with one or more markings. The marking data can include one or more marking locations within a geographic area and a type of infrastructure associated with each of the one or more marking. The drone is arranged to determine the location of the drone via one or more location sensors, receive data from the marking database, and deploy to each marking location within a portion of the geographic area. The drone is also arranged to determine whether each marking within the portion of the geographic area is sufficiently present using one or more marker sensors and repair each marking within the portion of the geographic area that is determined to not be sufficiently present.

Abstract: An autonomous marking apparatus comprising a propulsion system, a location sensor, a payload assembly, one or more marking sensors, a transceiver, a data store, and a processor. The location sensor is arranged to determine the location of the apparatus. The payload assembly is arranged to carry a payload of marking material. The one or more marking sensors are arranged to scan an area in proximity to the apparatus. The transceiver is arranged to exchange data with a remote server via a data network. The data store is arranged to store a portion of the data. The processor is arranged to receive data from the location sensor, the one or more marking sensors, and from the transceiver. The processor is also arranged to send data to the transceiver and control the delivery of the payload at the location of the apparatus.

Abstract: A marking identification system comprising a marking database, a drone, and a data network communicatively coupled to the marking database and drone. The marking database is arranged to store marking data associated with one or more markings. The marking data can include one or more marking locations within a geographic area and a type of infrastructure associated with each of the one or more marking. The drone is arranged to determine the location of the drone via one or more location sensors, receive data from the marking database, and deploy to the location within the geographic area. The drone is also arranged to detect one or more markings within the geographic area, detect an indicator in pain associated with each of the detected markings, and determine a type of infrastructure associated with each of the detected markings based on the detected indicator associated with each of the markings.

Abstract: A container for dispensing carbonated beverages and fluids sensitive to oxidation is provided. The dispenser contains a follower which communicates with the ambient environment through a one-way valve. The dispenser preferably includes a liquid flow rate and a flow velocity regulator to control the rate and velocity at which liquid is dispensed therefrom.
