1. A forklift RFID system for identifying RFID tagged pallets in a stack of pallets comprising:
- a) a forklift comprising a body, a mast mounted to said body and a fork assembly provided with a plurality of forks moveably mounted on said mast;
b) at least one RFID antenna secured in a fixed position on said fork assembly above the forks;
c) at least one RFID reader positioned on said fork assembly a fixed distance above said RFID antenna,d) said RFID antenna and said RFID reader being vertically movable with respect to the said forklift body while maintaining a constant spacing;
e) a user interface assembly including a touch-panel display mounted to said forklift body, said RFID reader being hardwired to said touch-panel display andd) software adapted to provide information to the touch-panel display identifying which RFID tags have been interrogated by the antenna and read by said reader, said software including filter means which retains tag identification for specific pallets which are being continuous read by said RFID reader

Abstract
A forklift RFID system on a forklift for a stack of pallets comprising:
- a forklift comprising a body, a mast mounted to the body and a fork assembly including forks moveably mounted on the mast. A RFID antenna is secured in a fixed position on the fork assembly above the forks of the forklift and a RFID reader is positioned on the fork assembly a fixed vertical distance above the RFID antenna. A user interface assembly including a touch-panel display, with the reader being hardwired to the touch-panel display is mounted on the forklift body and including a filter which retains tag identification for specific plastic pallets which are being continuous read by the RFID reader

17. A forklift RFID system for identifying RFID tagged plastic pallets in a stack of plastic pallets comprising:
-
a) a forklift comprising a body, a mast mounted to said body and a fork assembly moveably mounted on said mast, said fork assembly comprising a back frame mounted to said mast, a support frame mounted to said back frame and forks mounted to said back frame; b) at least one RFID antenna secured in a fixed position on said back frame above the forks of the forklift on a vertical axis with respect to the center point of said forks; c) at least one RFID reader positioned on said support frame at a fixed constant distance above said RFID antenna on a vertical axis with respect to the center point of said forks; d) said RFID antenna and said RFID reader being vertically movable with respect to the said forklift body; e) a user interface assembly including a touch-panel display, a keyboard and a removable data storage device, said reader being electrically connected to said touch-panel display and d) means to provide information to the touch-panel display identifying which RFID tags have been interrogated by the antenna and read by said RFID reader and filter means which retains tag identification for specific plastic pallets which are being continuous read by said RFID reader. - View Dependent Claims (18, 19, 20)
