  • Patent number: 11605460
    Abstract: Disclosed is a non-invasive method for assessing in a subject the presence and severity of a liver lesion, or the risk of death or liver-related events, including: 1) performing at least three binary logistic regressions on at least one variable, performed on the same variable(s) but each directed to a different single diagnostic target, thereby obtaining at least three scores; 2) combining the scores from step 1) in a multiple linear regression to obtain a new multi-targeted score; 3) optionally sorting the multi-targeted score obtained in step 2) in a classification of liver lesion stages or grades, thereby determining to which liver lesion stage or grade the subject belongs based on his/her multi-targeted score. Also disclosed is a single multi-targeted non-invasive test obtained by the combination of single-targeted non-invasive tests providing a unique score and a unique classification with improved accuracy compared to single-targeted diagnostic tests.

  • Patent number: 11087870
    Abstract: A system of tracing a dental prosthesis, the prosthesis including an electrical power source coupled with a radio-communications signals transmitter capable of assuming a weakly active state in which it periodically sends out signals at a first transmission frequency, and a highly active state in which it periodically sends out signals at a second, higher transmission frequency, and a presence sensor for sensing presence of the prosthesis in a mouth of a user, capable of delivering information on absence of the prosthesis in the mouth. The transmitter is configured to pass from the weakly active state to the highly active state when the sensor delivers information on absence of the prosthesis in the mouth. The system also includes a base forming a support of the dental prosthesis when not worn by a user, and the transmitter assumes the weakly active state on detecting the prosthesis in proximity to the base.
