Mikael Kais 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).

  • Current-voltage converter for the measurement of weak current capable of working under strong x or radiation
    Publication number: 20040027175
    Abstract: The invention concerns a current-voltage converter comprising electronic means (3,R) to supply a voltage (Vout)from a current (Iph). The converter comprises first means (4, K) to apply or not apply the current at converter input, second means (ECH1) to sample and memorize a voltage (Vout1) at converter output when the current is applied at converter input, third means (ECH2) to sample and memorize a voltage (Vout2, Vout3) at converter output when the current is not applied at converter input, and fourth means (S) for subtracting the voltage sampled and memorized by the third means (ECH2) from the voltage sampled and memorized by the second means (ECH1).

  • Radiation detector with semiconductor junction for measuring high rates of x radiation or gamma radiation dose
    Publication number: 20030168605
    Abstract: This invention relates to a radiation detector comprising at least one semiconducting junction capable of generating electron-hole pairs under the action of the detected radiation and connected in photovoltaic cell mode. The detector comprises means (8, 9, 10, 11, 12) for placing and maintaining the junction at an approximately constant temperature (TA).
