A monitor retraining device includes a handheld housing, a controller disposed within the housing, and a connector connected to the controller and connectable directly to a monitor having a screen. In particular embodiments, one or more layers are deposited on a substrate by plasma spraying over the substrate. Each gaming terminal includes a designation switch and an individual display and receives a bet by a player. The method of delivery can be made intuitive to the consumer by providing an actuator skirt that suggests the pumping mechanism or by providing a depiction of a hand or substrate over the pump dispenser. Upon detecting a network attack, the destination device selects a new network address for at least one of the source network address and the destination network address and establishes a new packet tunnel with the source device.
