Patent number: 7667603Abstract: RFID tags of very small size are embedded in products or composed of products in a manufacturing process. The system employs different read and write modes to enable auto-tracking of material, some assembly, assembly and component items through various stages of the manufacturing process. As each item passes special predetermined points in the manufacturing process, the embedded tag is activated and placed in track mode. The tag transmits its ID and a track count representing the number of stations passed. The tag's track count is incremented and the updated track count is stored in non-volatile memory in the tag. The tags can be programmed so that once the count exceeds a predetermined count, a status bit is set in the tag's memory indicating that the item has been completely through the manufacturing process. Thus, the system can determine whether an item or product has been completed. After manufacture the same RFID tag can be used for tracking, inventory and item authentication.Type: GrantFiled: April 13, 2006Date of Patent: February 23, 2010Assignee: Tagent CorporationInventors: Jarie G.

Patent number: 7317378Abstract: An electronic identification tag, usually in very small size, responds to a reader with an identification code unique to the object to which the tag is attached. The stand-alone device responds to a reader signal by storing energy received from the signal, then using the stored energy to generate another signal that is encoded with identification information. In operation, a reader generates RF energy which can reach a multiplicity of such tags over a distance of several meters. The system minimizes power requirements for the tag by minimizing intelligence in the IC. Use of a transmit frequency which is different from the reader's power frequency reduces interference between the power pulse and information pulse, eliminates the need for filters and enables the multiplied clock reference frequency as the transmit carrier frequency.Type: GrantFiled: August 17, 2004Date of Patent: January 8, 2008Assignee: Tagent CorporationInventors: Neil Jarvis, Paul A.

Patent number: 7257504Abstract: A radio frequency ID tag, very small in size and with an onboard antenna, is manufactured, tested and applied cost-efficiently. The transmit frequency for the tag is set during manufacture approximately, within a selected range, in a gross tuning step. A second tuning step fine tunes each tag by RF communication to set values of capacitance, resistance, etc., and this can be at the point of application of the tags. Other aspects include burning a randomly-selected value in the RF ID chip during manufacture to impose a random time delay for tag response (rather than having a random generator on the chip itself); structural testing of a large number of tags on a wafer using on-wafer interconnects and a special onboard sequencer test die; and production of the tag so as to be tunable to different frequency ranges.Type: GrantFiled: June 3, 2005Date of Patent: August 14, 2007Assignee: Tagent CorporationInventors: Jarie G.

Patent number: 7253716Abstract: A medical pill intended for human or animal consumption includes an RF ID tag in or on the pill. The tag will respond to a nearby reader, the tag itself being without a battery or other constant power supply, capturing power from the reader's transmitted signal and storing a portion of that power in a power supply. An antenna for the RF ID tag may be integral with the tag or it may be transferred to the pill using conductive materials in the pill's coating, filler or binding agents, embedded within the pill, or printed onto the pill. If separate from the tag the antenna is electromagnetically coupled to the tag which has a small onboard antenna. The RF ID tag of each pill has data that are transmitted when the tag is interrogated by a signal from a reader. Incorporation of an ingestable ID tag is possible because of the tag's very small size compatible with ingestion and because the tag can contain an antenna within the pill that allows the tag to be read at a substantial distance.Type: GrantFiled: November 19, 2004Date of Patent: August 7, 2007Assignee: Tagent CorporationInventors: Paul A.
