  • Patent number: 8701140
    Abstract: A broadband data broadcast system that allows rich multimedia content to be delivered to a plurality of subscribers is disclosed. The broadband data broadcast system operates by multiplexing a plurality of rich multimedia digital information streams together at a centralized data broadcast center. The data broadcast center then broadcasts the multiplexed digital information stream on a broadcast medium such as satellite broadcasts, radio frequency broadcasts, or digital television broadcasts. A large number of receiver systems receive the broadcast signal and demodulate the broadcast signal to retrieve the multiplexed digital stream. The receiver system extracts a subset of digital information streams that the particular receiver system's owner has designated are of interest. The receiver system caches the interesting digital information stream for later access. The receiver system outputs the interesting digital information streams to a client system upon demand.

  • Patent number: 7940675
    Abstract: In a 802.15.4 network, each reduced functionality device (RFD) is permitted to communicate with only an assigned full function device (FFD). The present invention allows each of the RFDs to communicate with another RFD upon the RFD determining that the local FFD assigned to the RFD is inoperable or unable to communicate. Under emergency conditions, the RFD is able to communicate with a closely located RFDs such that the closely located RFDs can receive and respond to an emergency situation and/or repeat the message. To satisfy the 802.15.4 standards, communication between the RFDs is allowed only during emergency conditions and when the FFD is inoperative. A comprehensive test procedure is included to insure the integrity of the system is preserved at all times.

  • Publication number: 20060088051
    Abstract: The present invention provides a method to statelessly compress an IPv6 header from forty octets to as small as or at a minimum of four octets by utilizing information contained in the lower network layers so that the original IPv6 header can be reconstituted as needed without state information maintained from and/or intermediate nodes. By compressing a typical forty octet IPv6 header into at a minimum four octets for transmission across a local area network, battery life for non-line powered local devices can be increased. When the package is to be sent outside of the local area network, the complete IPv6 header packet can be rebuilt prior to transmission.

  • Publication number: 20050033707
    Abstract: A system and method manage delivery of energy from a distribution network to one or more sites. Each site has at least one device coupled to the distribution network. The at least one device controllably consumes energy. The system includes a node and a control system. The node is coupled to the at least one device for sensing and controlling energy delivered to the device. A control system is coupled to the node and distribution network for delivering to the node at least one characteristic of the distribution network. The node for controls the supply of energy to the device as a function of the at least one characteristic.

  • Patent number: 6473858
    Abstract: A data broadcasting system is disclosed. The data broadcasting system operates by receiving source material from a number of different sources. The source material is processed by performing adding error correction encoding and in some cases, encryption. The source material from the different sources is then multiplexed together and broadcast on a broadcast medium. The multiplexed digital broadcast is received by a plurality of receiver systems. The receiver systems demultiplex the multiplexed digital stream to obtain desired digital streams. The desired streams are then decrypted if necessary.
