Joel Huloux 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: 6349111
    Abstract: The present invention relates to a circuit for allocating a channel to a transmission between at least two modems that use an electric network as a medium for the transmission of a binary data flow. The circuit includes, on the receive side, a device for selecting a channel that is selected for having the best transmission level according to the energy received on several transmission channels. The transmission of the binary data flow occurs, at least at the beginning of each communication on the several channels.
    Type: Grant

  • Patent number: 5933415
    Abstract: The present invention relates to a circuit for transmitting binary data on an electric network. The circuit includes a modulator, a demodulator and a digital circuit for controlling the modem and interpreting binary data. The circuit further includes a circuit for allocating a transmission channel to a communication and means for selecting, among several channels, an idle channel.

  • Patent number: 5768310
    Abstract: The invention concerns a data transmission circuit, for use on a mains electricity network, that includes a modulator/ demodulator circuit that supplies a first signal, which indicates if the network is occupied, that is based upon a comparison between the level of a received signal and a predetermined threshold value and circuitry for switching a modem into its receive mode or its transmit mode, including a digital circuit that supplies a second signal that indicates the occupation of the network based on the identification of a predetermined data sequence that is present within each transmission stream before a data message and circuitry for allowing the modem to switch to its transmit mode when the occupation signals indicate an absence of a transmission.
