Title: System and method for re-authentication of asynchronous messaging
Inventor: STOOPS DANIEL
IPC: G06F15/16
Filed: 2018-11-05
Abstract: A system and method are presented for the re-authentication of asynchronous messaging, specifically within enterprise to consumer communications. A third-party enterprise messaging server may be used as a conduit for a messaging service allowing for customer interaction with a business. The messaging server can append a re-authentication process for customers once a customer has been authenticated by the enterprise. Each time a customer resumes an interaction exceeding a timeout threshold, the messaging server invokes its re-authentication process. Lapsed interactions may be treated as continuous without having the customer re-authenticate through the enterprise specific authentication.

Title: Up-and-down floor for caravans and trailers
IPC: B60P3/32
Filed: 1997-03-13
Abstract: Floor consisting of a deck 01 with a base as backplate 02 that ascends and descends through the action of a lever 09 connected to the four corners suspended by steel cables 04. In operation, the movable floor is in the raised position, at a height of 0.25 m from the ground, for transporting obstacles on the highway. When parked, the floor descends 0.20 m, being at 0.05 m from the ground, thereby gaining 0.20 m in terms of interior useful height. The objective is, by virtue of this descending movement of the movable floor, to successfully reduce the total height of caravans or trailers to under 2.00 m, allowing entry through all garage doorways. The aerodynamic coefficient is also reduced, improving the consumption of the towing vehicles and alleviating the negative effect of side winds, meanwhile maintaining the habitable interior height at 1.86 m. <IMAGE>
