  • Patent number: 11499844
    Abstract: A proximity sensor having improved environmental compensation performance and an environmental compensation method in the proximity sensor are disclosed. The environmental compensation method and the proximity sensor advantageously reduce processing time, algorithm operation time, and power consumption by previously setting sensing values before sensing of sensors unlike a typical method in which compensation is carried out by multiplying factors obtained through software. Further, the environmental compensation method and the proximity sensor have an advantage of accurate compensation not only for linearly varying environmental factors but also non-linearly varying environmental factors.

  • Publication number: 20220251652
    Abstract: The present invention relates to a marker for predicting a tumor reactivity of lymphocytes, a composition for predicting a tumor reactivity, and a method for predicting a tumor reactivity. Using the genetic marker according to the present invention, a predictive model that can predict the tumor reactivity of cultured lymphocytes may be constructed, and it is possible to more accurately select tumor-specific lymphocytes to produce an effective immunotherapeutic agent, by predicting the reactivity of the lymphocytes through the present invention. In addition, by using the above genetic markers, it is possible to more conveniently and non-invasively separate lymphocytes from body tissues, blood, or body fluids, deviating from the conventional invasive methods, and to select only lymphocytes with tumor-specific activity, for immunotherapy.
