A scanner apparatus comprises a tunnel housing having a top, two sides and entrance and exit openings; a bed assembly having a top and side portions wherein the side portions of the bed assembly are substantially fixed to the side portions of the tunnel housing to form a substantially enclosed area; an isolating device located at each of the entrance and the exit of the tunnel housing; a conveyor device for moving an object though the tunnel housing; and an analysis device for analyzing objects within the substantially enclosed area in the tunnel housing. The scanner apparatus has an essentially frameless structure which enhances its capability for scanning tall, wide items.

Compact scanner apparatus and method

The present invention in one embodiment provides a metal detector comprising a coil, a circuit board on which the coil is etched, a digital signal processor, and a warning circuit, and battery power source. When a sufficient amount of metal is near the coil, the digital signal processor activates a device or devices in the warning circuit. In another embodiment the circuit board on which the coil is placed is used in conjunction with a one piece molded housing. In another embodiment the present invention, provides a metal detector comprising an elongated coil etched onto an elongated circuit board. At least one active device, which is part of detection circuitry is also preferably placed on the elongated circuit board. The detection circuitry in one embodiment, includes circuitry which together with the elongated coil forms an oscillator circuit. The elongated covering case in one embodiment is molded substantially seamlessly by blowmold, extrusion, or injection mold.
