DEVICE FOR DETECTING OBJECTS BEHIND A SURFACE |
摘要 |
<p>A device for detecting objects (126) behind a surface (125) comprises a row of capacitive sensor plates (116a-116i) and a corresponding row of display elements (120a-120i). As the device is moved over the surface (125) the capacitor plates (116a-116i) sense variation in the apparent dielectric constant caused by the presence of an object (126) behind the surface (125). The display elements (120a-120i) change their display accordingly and present a visual representation of the object (126) and of edges of the object (126).</p> |
