Abstract: A user engagement system includes a network interface, a content storage device and a ticket activation module. The network interface allows users to connect to the user engagement system through a network. The content storage device stores content for user engagement. A ticket activation module, displays a ticket in a first state when a user is not eligible to participate in a daily drawing, and the ticket activation module displaying the ticket in a second state when the user completes an activation process and is eligible to participate in a daily drawing. An invitation module presents to the user an invitation webpage that allows the user to invite others to join the user engagement system. Additional users who join the user engagement system as a result of an invitation from the user are added to the user's profit sharing community.

Abstract: A source (100, 101, 200, 300, 400) of a beam of positive ions or atoms comprises an ion-emission pellet (1, 401) consisting essentially of a solid electrolyte. Preferred solid electrolytes for the pellet (10, 49) are alkali or alkali-earth mordenites. A pellet heater is capable of heating the pellet (1, 401) to an ion-emission temperature at which ions are emitted from the pellet. A beam-forming electrode (2, 4, 31, 60) contacts an ion-emission surface (22) of the pellet (1, 401). The beat-forming electrode (2, 4,31, 60) has at least one passageway extending through it into which ions from the ion-emission surface (22) can pass. Ions emitted into the passageway are discharged from the source as unneutralized ions or neutralized atoms.
