Mark Leifer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8135379
    Abstract: A portable telecommunications system (PTS) allows mobility and rapid deployment with minimal on-site configuration. PTS systems exchange multicast packets including location and identification information. A protocol manager sets up these communications channels, manages exchanges between PTS systems, and passes the data to or from internal system nodes. The PTS system detects when another PTS system is operating in close physical proximity and automatically perform actions, such as adjustment of transmission power level, to maintain service to the user base.
    Type: Grant

    Date of Patent: March 13, 2012
    Assignee: Telefoanktiebolaget L M Ericsson (Publ)

  • Patent number: 8027272
    Abstract: A portable telecommunications system (PTS), and discovery and update protocol provides an ad-hoc system in which PTS systems can detect one another over a wide area network (WAN). The system may be compact in a way that allows mobility and rapid deployment with minimal on-site configuration. PTS systems exchange multicast packets and peer-to-peer data exchanges. A protocol manager sets up these communications channels, manages exchanges between PTS systems, and passes the data to or from internal system nodes. The protocol manager also performs key oversight functions such as signaling to other systems that a PTS is joining or leaving the community, keeping track of which other PTS systems are in the community and active, and determining when data needs to be updated and exchanged.

  • Publication number: 20070015545
    Abstract: A method and apparatus is described for modifying a smart antenna processing strategy determined from a set of signals received at an array of antenna elements of a wireless station, such as a set of weights for processing received antenna signals or forming a set of antenna signals for transmission. The method and apparatus uses the signatures of one or more interferers to produce a modified processing strategy that improves the nulling to the one or more interferers in that, when the modified strategy is applied on the downlink, the transmit signal strength in the direction of the one or more interferers is decreased, and, when the modified strategy is applied on the uplink, the sensitivity to signals from the direction of the one or more interferers is decreased.
