  • Patent number: 8010882
    Abstract: Methods and systems for modifying DOCSIS-based transmission paths for communication in higher frequency and/or wireless environments, such as wireless terrestrial communication systems and satellite communication systems. An inner turbo-code is combined with a DOCSIS based Reed-Solomon (“RS”) forward error correction (“FEC”) coding scheme, to produce a concatenated turbo-RS code (other FEC codes can be utilized). In phase and quadrature phase (“I-Q”) processing is utilized to enable relatively low cost up-converter implementations. The I-Q processing is preferably performed at baseband, essentially pre-compensating for analog variations in the transmit path. Power amplifier on/off control capable of controlling on/off RF power control of remote transmitters is modulated on a transmit cable to reduce the need for a separate cable.

  • Patent number: 8009815
    Abstract: The invention is a message distribution system that can deliver a single message to a large number of people with a single act using a group of computer servers. The preferred embodiment requires the user to establish an account using a website and enter a contact list. The contact list can include both email addresses and telephone numbers. When the user wishes to send a message, at a later time, the user contacts the group of computer servers by a telephone number or email address. The user records a message on the servers and the server sends the messages to all email addresses and telephone numbers on the contact list for that user. Other embodiments include procedures to confirm the validity of the email addresses and telephone numbers and to confirm the delivery of messages to the email address and telephone numbers on the contact list.

  • Patent number: 8006775
    Abstract: A strip tillage implement includes a plurality of forward disk gang members for sizing plant residue. An upright tool support bracket extends rearwardly from the rear frame member and defines a downwardly opening accommodation space at a top portion of the bracket for a closing disk assembly rockshaft or support. The bracket includes a lower end supporting a parallel linkage that carries a clearing tool assembly in a generally constant horizontal attitude as the linkage pivots with movement of the clearing disks over obstacles. A tool support arm is pivotally connected to the bracket adjacent the parallel linkage and below the rear frame member. A closing disk arm supported from the rockshaft can be rotated to adjust down pressure or to lift the closing disk is completely out of ground contact. Closing disk spacing and disk angle are adjustable to provide the desired berm shape.
