Abstract: Disclosed are an in-cabin safety sensor for predicting a driver state and its driver state predicting method. The in-cabin safety sensor for predicting a driver state using radar of the present invention may count a driver's heart rate and/or respiratory rate using radar, and may monitor changes in the driver's heart rate or respiratory rate to predict driver's drug use, hypoglycemic shock, etc., in which the driver's heart rate per minute counted in real time is higher than the reference heart rate or the driver's respiratory rate per minute is higher than the reference respiratory rate, in addition to driver's drowsy driving or preliminary drowsy driving in which driver's heart rate per minute counted in real time is slower than a reference heart rate or driver's respiratory rate per minute is lower than a reference respiratory rate.

Abstract: A touch screen panel is disclosed, which is capable of sensing an exact position touched by a user or instrument, or a pressured applied to the touched position, wherein the touch screen panel comprises a core including a plurality of horizontal and vertical lines provided in a grid shape, wherein the core has a first refractive index, and an upper surface of the core is exposed to the atmosphere; an intermediate clad formed between each of gaps included in the core, wherein the intermediate clad has a second refractive index which is lower than the first refractive index, and a height of the intermediate clad is identical to a height of the core; an optical source configured to apply an optical signal to an input end of each of the plurality of horizontal and vertical lines; and a plurality of receivers configured to sense an intensity of the optical signal passing through an output end of each of the plurality of horizontal and vertical lines, the optical signal applied by the optical source.
