Abstract: A nozzle and tank assembly includes a dump trailer that is attachable to a truck and a fluid tank mounted to the truck. A pump is disposed on the fluid reservoir for pumping a lubricant contained in the fluid tank. A spray bar is attached to the dump trailer and the spray bar has a plurality of spray nozzles each directed into the dump trailer. A supply line is fluidly attached to the pump such that the supply line receives the lubricant when the pump is turned on. The supply line is fluidly coupled to the spray bar such that the supply line delivers the lubricant to the spray bar thereby facilitating the spray nozzles on the spray bar to spray the lubricant into the dump trailer. In this way the lubricant inhibits cargo from sticking to the dump trailer when the dump trailer is actuated into a dumping condition.

Abstract: Authentication method and systems using RFID-enabled payment cards are disclosed herein where a server receives a request corresponding to authorization of a payment associated with a payment card from an electronic terminal. The server identifies an electronic device of a user associated with the payment card. The server then transmits an instruction to the electronic device to cause an RFID reader of the electronic device to determine whether an RFID tag corresponding to the payment card is located within a predetermined proximity to the electronic device. When the payment card is located within the predetermined proximity, the server executes a first authentication protocol. Moreover, when the payment card is not located within the predetermined proximity, the server executes a second authentication protocol, wherein the second authentication protocol is more restrictive than the first authentication protocol.
