    Abstract: A method and device enables reading radio frequency identification (RFID) tags in a localized area. The method according to one embodiment includes commencing transmission of an interference signal from a reader device (step 505). A command signal is then transmitted from the device while the interference signal is still being transmitted (step 510). The command signal instructs non-target RFID tags to not respond to an interrogation signal, and the target RFID tags do not process the command signal because the command signal is blocked by the interference signal. Transmission of the interference signal from the device is then stopped (step 515). The interrogation signal is then transmitted from the device after the interference signal is no longer being transmitted (step 520). Finally, a response signal is received at the device from the target RFID tags that enables the device to read only the target RFID tags (step 525).

    Abstract: Described herein are methods, devices and systems for characterizing an attached antenna to an electronic device, such as a radio frequency identification (“RFID”) reader. One exemplary embodiment is related to a method comprising outputting a low amplitude modulation (“AM”) index radio frequency (“RF”) waveform, the waveform simulating tag data timing and bandwidth, removing a direct current (“DC”) component from the waveform to create a chopped portion of the waveform, applying at least one vector analyzer technique on the chopped portion of the waveform, characterizing at least one antenna impedance vector of the waveform.

    Abstract: A dual-mode RFID reader is capable of automatically switching from a far-field interrogation mode to a near-field interrogation mode upon the detection of certain operating or handling conditions. The RFID reader includes an RFID radio module configured to support a far-field interrogation mode and a near-field interrogation mode, an antenna arrangement coupled to the RFID radio module, and a mode-switch sensor architecture coupled to the RFID radio module. The mode-switch sensor architecture is configured to detect conditions indicative of near-field interrogation, and the RFID radio module automatically configures itself for operation in the near-field interrogation mode upon detection of such conditions.

    Abstract: Some computer operating systems do not permit application programs to perform certain tasks. If there is a desire to perform a forbidden task, a virtual partition (228) is created (610) in a storage device (108), such as a hard disk drive, associated with the computer system (100). The virtual partition (228) is stored as a file within the file system of the storage device (108). Operating system files (414) are installed in the virtual partition (228), and the storage device (108) is configured (616) to boot the computer system (100) using the operating system in the virtual partition. When the task is complete, the computer system (100) is configured to boot using the operating system other than the one in the virtual partition.
