Title:
液滴スプレー口腔清浄化装置とともに使用される表面検出システム
Document Type and Number:
Japanese Patent JP5192484
Kind Code:
B2
Abstract:
The surface detection system includes a source of an optical interrogating signal (44) which accompanies a droplet spray in an oral cleaning device directed to an oral surface (46). The interrogating optical signal is reflected from the oral surface which the spray impacts and detected (48). A selected characteristic of the reflected signal, such as intensity, is indicative of the nature of the oral surface, such as either gum tissue or a tooth surface. The detected reflected signal is then processed to determine the nature of the oral reflecting surface. The processor (50) then provides a resulting output signal which can be used to either warn the user concerning the nature of the oral surface or to change the characteristics of the spray appropriately according to the surface (51).
