ABSTRACT:
Detecting wear through use of information-transmitting devices. At least one information-transmitting wireless device is provided for each of one or more wear positions of an item, wherein each of the devices is adapted for transmitting information to a reader, such that each of the devices can transmit information usable for detecting wear of the item as the item wears. When using a plurality of devices for a particular wear position, the devices may be stacked or placed in a depth-wise, end-to-end arrangement. As another alternative, a single device having a plurality of separable areas may be provided for each of one or more wear positions. As yet another alternative, a single device may be provided for each of one or more wear positions such that its failure to transmit indicates wear at the corresponding wear position. An information-transmitting device may become damaged or missing, due to item wear, and an RFID reader may therefore be unable to scan (i.e., receive data from) the device.
