Patent ID: 8669846

Claim:
A method for automatic tracking and verifying of a process using a proximity sensing system, said system comprising a reader and a plurality of antenna probes located on a human and a plurality of wireless transceivers located on an item or at a location used in the process, and said method comprising the steps of: adjusting the power of said reader to determine a location of the antenna probe located on the human relative to the wireless transceiver, and recording when the location of the antenna probe located on the human is a desired distance from the wireless transceiver, thereby locating and tracking the wireless transceiver in the process wherein the step of adjusting the power of the reader is performed by the steps of: (a) reading at the reader the plurality of the wireless transceivers positioned at different locations on the item using the plurality of the antenna probes; (b) detecting one or more of the wireless transceivers by each of the antenna probes and determining if the wireless transceivers detected by each of the antenna probes are different; and (c) if the wireless transceivers detected by each of the antenna probes are different, decreasing a transmit power of the reader of each of the antenna probes and repeating steps (a) and step (b) until only one wireless transceiver is detected by the antenna probe.
