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： Described is a system comprising a computing device detachably coupled to an input arrangement. Upon authenticating a user, a corresponding user profile is retrieved from a memory module and uploaded into at least one of the device and the arrangement. The profile stores user's preferences for inputting data via the input arrangement. The memory module is situated in at least one of the device and the arrangement.
