Abstract: A system and method for dynamic email addressing is disclosed. A proprietary mail transfer agent and processors within a proprietary environment including a persona processor enable email users to define email addresses, both in terms of which email addresses are recognized or not, and which email addresses should be organized according to persona. In another aspect, email users choose to be conditionally notified of the arrival of a new message via push notifications. Users choose to receive push notifications only for personas users deem important enough to interrupt current activity. According to an embodiment, push notifications are generated and sent via any current user communication channel.

Abstract: A bi-directional advance gear having a torque limiting radial friction clutch is disclosed. The friction clutch comprises an annular member having an inner and outer periphery and having gear teeth defined by its outer periphery and radially inwardly projecting teeth on its inner periphery. A flat web substantially closes one face of the annular member to provide a shallow recess bounded by the projecting teeth and defines an opening concentric to the annular member. An inner member having a hub portion is rotatably mounted in the opening and has a pinion gear at one end. The other end of the hub has a plurality of radially extending rosette-shaped springs contained in the recess. Each spring has a pair of radially extending leg portions joined by an arcuate portion. Each arcuate portion has a lobe biased into engagement with the inwardly projecting teeth.
