PHYSIOLOGICAL ACTIVITY/INACTIVITY DETECTION DEVICE BASED ON OPTICAL FIBER
ES2610181
Activity detection device/physiological inactivity configured to allow the detection of activity states or physiological inactivity of people, in a non-intrusive way and without direct contact, based on the detection of movements and vibrations using the measure of changes in the pattern speckle produced in a multi-mode optical fiber (14, 24, 34, 44) when conducting coherent light inside, comprising: at least one multi-mode optical fiber (14, 24, 34, 44) as an element of transduction, linked to a coherent light source (12, 42) and to an optical detector (11, 41); a processing block (13, 43) connected to the optical detector (11, 41), configured to implement the processing method necessary to issue a decision; connecting elements (15, 45, 55) configured to connect/disconnect the multi-mode optical fiber (14, 24, 34, 44) to/from the optical detector (11, 41) and/from the coherent light source (12, 42). A processing method configured to detect the activity states or physiological inactivity of people, using the defined device. (Machine-translation by Google Translate, not legally binding)
