A hitch assembly, including a first frame for being attached to a tow vehicle and a second frame for being attached to a trailer. The second frame is movably engaged with the first frame and is adapted for fore and aft movement relative to the first frame along a plurality of ball bearings.

Hitch assembly

A hitch assembly including a frame for being attached to a tow vehicle; a cradle assembly pivotally attached to the frame for pivotal fore and aft movement; a hitch receiver mounted to the cradle assembly for being attached to a trailer; a leaf spring mounted to the cradle assembly and the fore end of the frame for controlling fore and aft movement of the cradle assembly; and shock absorbers mounted to the cradle assembly and the aft end of the frame for dampening fore and aft movement of the cradle assembly.

This present invention provides users with secure transparent electronic communication, allowing them to send and receive encrypted and/or signed messages with little or no user involvement. In various embodiments, the present invention provides a user with e-mail security via automated hierarchical techniques for transparently sending and receiving secure messages, and lowers the burden on administrators. Such a system can also manage cryptographic keys and certificates for the users, and creates such keys and certificates for the users when necessary. A server according to the present invention can intercept unsecured messages from a user, automatically transform those messages into secured messages, and transmit those secure messages to the intended recipients. The server can also automatically transform messages after the recipient sends a digital identity to the server and downloads the software necessary for transforming the secured messages back into readable messages (i.e., from ciphertext into plaintext). The server can further intercept an unsecured message from a user, search for a digital identity of the intended recipient, secure the unsecured message upon finding such a digital identity, and transparently send the secured message to the intended recipient.

System and method for secure electronic communication in a partially keyless environment

The invention includes a computer readable medium storing executable instructions to enroll a user with a secure email support facility. The computer readable medium includes executable instructions to send an enrollment message, supply a registration response, and confirm the registration response. An authentication email is also sent. A client identifies the authentication email. Authentication information within the authentication email is decrypted. The authentication information is used to authenticate the client and subsequently obtain access to a secure email support facility.
