In a preferred embodiment, an object orientation sensor device, including: a first LC tag disposed at a first selected location in the object; a driver/reader circuit disposed so as to detect the presence of the first LC tag when the object is in a first orientation and to not detect the presence of the first LC tag when the object is not in the first orientation; and the driver/reader circuit being arranged to energize the first LC tag with a magnetic field and to subsequently detect a first resonant frequency echo produced by the first LC tag when the magnetic field is removed.
