  • Patent number: 12252555
    Abstract: A selenium-chelating pea oligopeptide, a preparation method thereof and use thereof. After the selenium-chelating pea oligopeptide is subjected to digestion treatment in at least one of following three ways, a change rate of selenium content not more than 3% with respect to the selenium content before the digestion treatment: hydrolyzing for 4 hours by a pepsin at a pH value of 2 and a temperature of 37° C.; hydrolyzing for 6 hours by a trypsin at a pH value of 7.5 and a temperature of 37° C.; maintaining the temperature constant at 37° C., firstly hydrolyzing for 4 hours by the pepsin at a pH value of 2, and then continuing to hydrolyze for 6 hours by a trypsin at a pH value of 6.8. The preparation method thereof includes mixing and reacting an aqueous solution of pea oligopeptide and sodium selenite, and then being subjected to alcohol precipitation and drying.

  • Patent number: 7571326
    Abstract: A method for authenticating user access by a user to an electronic device. The method includes measuring a first plurality of relative latency values as keystrokes pertaining to an authentication process are entered. The method further includes determining whether the first plurality of relative latency values meet established statistical standards based on a previous plurality of relative latency values obtained from the user. The method also includes permitting the user access if the first plurality of relative latency values meet the established statistical standards based on the previous plurality of relative latency values obtained from the user.
