摘要： Systems and methods for opportunistically charging a rechargeable power source of a portable electronic unit are provided. The system includes a primary inductance assembly energized by a main power source for inducing an electro-magnetic flux in a secondary coil assembly associated with a power source of the portable unit. Such electro-magnetic flux creates an electric current that is subsequently employed for charging the power source of the portable unit. A controller of the charging system can monitor state of charge, and notify a user when a recharge is required. Scavenging modes may also be employed for recharging the main power source and the rechargeable source of the portable unit.

摘要： The location of unmodified wireless assets in a wireless communication network may be identified using time differences of arrivals of a communication sequence at different network receivers. Time-stamping devices may include correlator circuits in parallel with signal decoders to time-stamp communication sequences. Cellular wireless networks may be frequency-multiplexed to increase spatial time-stamping density. Tags may be attached to passive assets to provide location identification information to network devices. Locations of assets broadcasting standard 802.11 radio frequency structures may be identified. Noise inherent in correlating a communication sequence may be reduced by using a selected correlation function.

摘要： A locating and tracking system is provided in which the assets are desired to be located and tracked are associated with either radio frequency (RF) tags or radio frequency identification and radio frequency data communication (RFID/RFDC) devices. Depending on which device is attached to the asset, the other device is located at known locations. The RFID/RFDC devices interrogate and receive signals from the RF tags. The received information is sent to the host computer. With the location of either the RF tags or the RFID/RFDC devices known, the assets may be located and tracked. An improved RF tag antenna design is also provided by using a switching mechanism connected to at least two antennas.

摘要： Methods and apparatus are provided for locating one among many items equipped with RFID tags. The apparatus comprises a portable system interrogating the RFID tags and receiving responses therefrom that depend at least on their bearing angle. A comparator selects responses from the one item and ignores others. An annunciator indicates the presence of the one item in the interrogator field of view and, desirably but not essentially, its relative proximity. A directional antenna whose beam pattern is limited in azimuth and/or elevation provides bearing angle information. Its field of view becomes progressively smaller as the antenna approaches the one item so that a user can substantially pinpoint its location without needing any of the usual RFID infrastructure. Tag response hit rate and/or signal strength provides range related information to the interrogator. Optionally, the presence of each new tag is announced until all new tags have been identified.

摘要： Methods and apparatus are provided for automatically and autonomously forming a wireless personal area network (WPAN) from an array of intercommunicating personal area network (PAN) devices. The devices comprise first communicators associated with primary functions of the devices and second communicators coupled to the first communicators for determining a subset of the devices meeting predetermined association criteria, from which subset the first communicators form the WPAN. In a preferred embodiment, the second communicators include range measuring transceivers and processors coupled to the transceivers that cooperate to determine range and relative motion of elements within communication range of the first communicators for comparison to range and relative motion association criteria stored in one or more of the devices. Memory is desirably included for storing the association criteria. The subset of devices automatically elects a master device that communicates with the other devices of the subset to form the WPAN.

摘要： A method is provided for optimizing the design parameters of a RFID tag for use with a RFID reader in a RFID system. In the method, a desired frequency band that the RFID tag will operate in is chosen. Additionally, a maximum acceptable cost for the RFID tag, a minimum acceptable data range for the RFID tag and a minimum operating voltage for the RFID tag are chosen. For a given cost, an optimal data rate is calculated by varying a carrier modulation period of an interrogation signal generated by the RFID reader and antenna capacitance of the RFID tag. Next, an optimal range for a given operating voltage is calculated using the optimal data rate.
