Abstract: A method for homing a stepping motor having a plurality of full-step positions within each full rotation of a rotor of the stepper motor includes applying a first drive current to windings of the stepper motor to rotate the rotor at least one full rotation in a first direction away from an end-of-travel (EOT) position. Thereafter, the drive current is applied to the windings to rotate the rotor in a second direction toward the EOT position. Upon detection of EOT, the drive current is discontinued. Drive current is then applied to the windings to rotate the rotor of the stepper motor in micro-steps in the first direction to a closest full-step position of the stepper motor. Finally, a drive current is applied to drive the stepper motor a predetermined number of full steps away from the EOT position.

Abstract: Implementations of the present disclosure may include systems and methods for providing an improved bingo game based on player defined custom bingo cards and mapping the player defined custom bingo cards to simulate other games, such as, but not limited to, wheel based games such as roulette, dice games, and other suitable games. Implementations of the system and method may include receiving messages comprising one or more player wager selections from the plurality of electronic player interfaces, wherein the one or more player wager selections comprise one or more player selected game patterns. Implementations of the system and method may include creating one or more custom bingo cards based on the one or more player selected game patterns received in the one or more player wager selections.

Abstract: A system and method for improving the download time of emails in an environment in which a server distributes emails to persons working in close proximity to each other. When these persons receive multi-recipient emails intended for several or all of these persons, the server distributing the emails delivers the multi-recipient emails to the first one of the persons who logged on to read his or her emails on his or her personal computer, for distribution to the other persons over a personal area network. This reduces the download time for the persons downloading their emails at a subsequent time.

Abstract: An improved exhaust system and method for an apparatus that removes support material from additively manufactured parts is disclosed. The apparatus includes an enclosed chamber in which the additively manufactured parts are placed. A heated detergent fluid is sprayed at the additively manufactured parts. The improved exhaust system exhausts heated air from the chamber. The improved exhaust system includes an exhaust channel having an inlet end open to the chamber through which heated air from the chamber is caused to flow. Relatively cooler air is caused to flow across the outside of the exhaust channel. When the heated air from the chamber encounters the exhaust channel across which the relatively cooler air is caused to flow, evaporated fluids in the heated air condense and fall back into the chamber. The improved exhaust system can be retrofitted onto older models of the support removal apparatus that do not have the improved exhaust system.
