A resonant antenna circuit for a radio frequency identification reader generates an electrical signal for activating a passive identification tag. In one embodiment, the invention may include gathering video data from a video source, gathering non-visual video information associated with the video data, maintaining a current state of the video information in storage, and annotating the video data with the current state of the video information. Adjacent the top opening along opposed long sides are two tubular members with an end aperture dimensioned for insertion of a finger into each tubular member. After the portion of particulate material containing the piece of tramp metal has been redirected by the redirection device, the system resumes normal operation.
