Dan Constantinescu 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: 12468504
    Abstract: The disclosed communication skills training tool identifies and analyzes target user data from a multi-user collaboration tool or a live event to provide communication skills training feedback to a target user. The target user is identified based on target user characteristics in the received signal from the multi-user collaboration tool or an input at the live event. A target user performs in a communication event with multiple users on a multi-user collaboration tool or a live event. A signal that includes data from the target user and excludes data from the other users is analyzed to determine feedback appropriate for the target user. That analyzed data is output either in real-time or asynchronously via post-event review.
    Type: Grant

  • Patent number: 4510925
    Abstract: The present invention relates, on the one hand, to a therapeutic method consisting in transmitting magnetic signals to a living substratum or body which signals have informational significance compatible with the informational organization and the automatic regulation of the substratum in order to act on its functional behavior to balance or dynamize it, and on the other hand, to an apparatus for transmitting said signals. Each signal is formed by a sequence of magnetic fields generated by selectively coupling an electrical signal into like and dissimilar magnetic poles to define a wave train of selected form, the wave train being repeated at least three times, the basic frequency of the magnetic waves being of the order of 40 to 80 KHz, and the signal duration being of the order of 100 to 200 microseconds.

  • Patent number: 3988428
    Abstract: Sulfur dioxide is formed by the combustion of elemental sulfur in two distinct stages wherein oxygen-containing gas in a quantity which is initially less than that stoichiometrically required for total combustion of the sulfur to sulfur dioxide and the sulfur-dioxide gases and residual elemental sulfur are thereupon passed through a heat exchanger and subjected to an afterburning with additional quantities of oxygen-containing gas. 70% to 95% of the total oxygen required for combustion of sulfur is supplied in the initial or combustion stage and the remainder (i.e. 30 to 5%) is supplied in the afterburning stage.
