Abstract: A system is provided including a current sensor arranged to sense current drawn by an electric motor of a powered device through an AC power line from a power supply and provide current data related to the powered device; a monitoring device arranged to receive the current data from the electrical sensor, the monitoring device including a controller processing the current data to obtain performance data associated with the powered device, the performance data relating to load applied to the electric motor; a data communication device communicating with the monitoring device and arranged to receive the performance data associated with the powered device; and a computing device including a graphical user interface, the computer device receiving a user's selection of the powered device from a list of powered devices and presenting the performance data to the user via the graphical user interface in response to the user's selection.

Abstract: A bubble-propelled amusement device in which play pieces are dispersed in a water bath contained in an enclosed transparent tank having on its bottom wall an air nozzle and having in the air space above the bath an air intake, the pieces normally tending to sink toward the nozzle. Below the tank is a pump assembly comprising an air chamber coupled to a player-operated bellows, the chamber being provided with an air outlet and an air inlet, each having a check valve therein. The air outlet is coupled to the nozzle so that when the bellows is actuated by the player and compressed, the resultant positive air pressure in the chamber causes the outlet valve to open to feed air into the nozzle which injects into the water bath a stream of air bubbles that act to propel play pieces toward a target, the bubbles then being discharged into the air space.
