GUM DETECTION IN A DENTAL HYGIENE DETECTION APPARATUS BY STREAM PROBE BLOCKING |
摘要 |
A detection apparatus (400, 1100) detects the presence of a substance (116) on a surface (31, 33) based on measurement of a signal of obstructing the passage of second fluid (30) through a first stream probe and confirmation that the substance is not the gums of a subject or a user of the detection apparatus and not the generation of a false alarm signal that the substance is the gums of the subject or of the user of the detection apparatus by comparing to a signal of at least partial obstruction to a signal correlating to an object not obstructing the passage of fluid (30) through a second stream probe (402). The signals may include pressure, flow rate and strain. |
