Patent attributes
A wall scanner that includes a housing, a plurality of sensors, a display, and a control section. The housing includes a handle portion and a body portion. The handle portion is adapted to receive a removable and rechargeable battery pack such as a high-voltage lithium-ion (“Li-Ion”) battery pack. The body portion of the housing encloses the plurality of sensing devices, such as capacitive plate sensors for sensing the presence of a stud behind a surface, a D-coil sensor for identifying the presence of metal behind the surface, and a non-contact voltage sensor. The display is configured to display the location of an object behind the surface in real-time, the depth of an object behind the surface, and whether an object behind the surface is ferrous or non-ferrous. The control section includes actuation devices for controlling the functions and operations of the wall scanner, such as the scanning mode.
