Abstract:
An RF tag (20) includes a low profile battery power source (22). The RF tag includes an electrically insulating substrate (21), an RF transmitter (24) on the substrate for transmitting a predetermined identification code, and the battery (22). The battery includes a first pattern of conductive material to form a planar anode structure (48) and a second pattern of conductive material on the substrate to form a cathode structure (50). A protective layer (92) overlies the substrate. The protective layer includes an opening (94) to expose the anode and cathode of the battery to permit an electrolyte to be applied to the anode and cathode for completing the formation of the battery and to provide electrical energy to the RF transmitter. A manufacturing apparatus (60) is also described which permits the RF tags to be manufactured in a low cost, reel-to-reel, basis. Also described is a dispenser (100) for activating and dispensing the RF tags one at a time at a point of use.
Abstract:
An RF tagging system including an RF tag (10, 30) and an RF tag reader (80). The RF tag includes a plurality of RF resonant circuits. Each RF resonant circuit is resonant at a different specific frequency. Each plurality of RF resonant circuits divided into a group of decoder circuits (12, 32) and a group of data RF circuits (14, 34). The group of data RF circuits have resonant frequencies corresponding to a predetermined identification code when the resonant frequencies of the data RF circuits are decoded in accordance to the one decoding modality. The RF tag reader detects the resonant frequencies of the decoder RF circuits to determine the one decoding modality. The RF tag reader is operative in each of the predetermined decoding modality. The decoder RF resonant circuits may also indicate the number of data RF resonant circuits on the RF tag. The RF tag reader determines the number of RF circuits from the decoder RF resonant circuits to confirm the accurate detection of the data RF resonant circuits.
Abstract:
An RF tag (10) includes a plurality of RF resonant circuits (14, 18, 22) which are disposed in a three-dimensional array within a body (30) of solid material. Selected ones of the RF resonant circuits are coated with a conductive ink (36) for programming the RF tag. Non-planar RF resonant circuits (40, 50) provide enhanced directivity. The RF resonant circuits (14, 40, 50) are disposed within an elongated body (72, 82, 94) in spaced apart and substantially axially aligned relation to provide elongated RF tag configurations. An RF tag assembly (110) includes attachment mechanisms (116, 118) for attaching an RF tag (128) to a carrier. A dual mode RF tag assembly (140) is also provided which includes a passive RF circuit (144) and an active RF circuit (142).
Abstract:
RF tagging system (10) has a plurality of resonant circuits (13) on a tag (12). When the tag (12) enters a detection zone (14), the system determines the resonant frequencies of each of the resonant circuits (13) and produces a corresponding code. Preferably, resonant frequency detection is implemented by simultaneously radiating signals at each possible resonant frequency for the tag circuits (13). The system is useful for coding any articles such as baggage or production inventory. Preferably, the radiated signals are phase shifted during the detection process, and signals received by receiver antennas, besides transmitter signals, may be monitored to improve the reliability of detecting the resonant circuits (13). Also, a preferred step adjustment configuration for capacitive metalizations (106, 110) of the resonant circuits is described. For radiating signals into the detection zone (14), focused beam antennas (201) may be used such that each resonant circuit location on the tag can be separately monitored. Also, an apparatus (300) for producing customized resonant circuit tags in accordance with a specified input code is described.

An integrated circuit module (501), with enclosed semiconductor devices (107, 115), includes a housing (101) with an electromagnetic wave reflective interior surface (103). A transmitter (105), mounted on a semiconductor device (107), transmits signals derived from a semiconductor device (107). An electromagnetic wave receiver (113), is positioned in the housing (101) such that it receives a transmitted wave via a reflective surface (103) along an electromagnetic wave path (117) from the transmitter (105).

A guidance device (101) determines direction, and indicates with a discrete transition indicator (104, 106, 108) when the guidance device axis is aligned that direction. This is accomplished through the integration of a radio navigation receiver, in this case a GPS receiver (203) and a flux-gate compass (205) in a hand held unit with a user interface including a keypad (110), a direction display (119) and a configurable display (115).
Abstract:
Vehicle route planning system (10) has in-vehicle route planning computer (12) which receives trip data, including at least one destination. Trip data is provided to the computer either by wireless communication link (20B) between remotely located radio transmitter (44) and vehicle antenna (20) or by remotely located media writer device (46) writing the trip data on removable storage media device (30) which is then provided to an in-vehicle media reader device (31). Vehicle operator enters trip data into remotely located apparatus (at 40) which translates trip data into electrical signals that are subsequently coupled to the in-vehicle computer (12) which uses data for calculating desired vehicle route to specified destination via fixed road paths. Preferably the system (10) is a vehicle navigation system (10) which utilizes radio receiver apparatus (20, 21) for transmitting the trip data to the in-vehicle computer (12) and also for coupling dynamic route traffice information, other than information specified by the vehicle operator, to the in-vehicle computer (12).
