    摘要： An embodiment of the present invention provides a system including a plurality of radio frequency identification (RFID) tags and a reader. Each RFID tag of the plurality of RFID tags backscatter transmits a signal. In one embodiment, the reader includes a plurality of antennas and a signal processor. In another embodiment, the system includes a signal processor and a plurality of readers each including an antenna. In either embodiment, each antenna receives a plurality of signals corresponding to the backscatter transmitted signals. The signal processor combines the received plurality of signals to produce an output signal.

    摘要： Systems and methods that automatically register a mobile computing unit (220) on a wireless network area (242), via employing a voice recognition system associated with the mobile computing unit (225). A handshake can occur between a mobile computing unit and a server of the network upon utterance of predetermined voice (e.g., a sequence of letters) by the user into the voice recognition component. As such, a mass deployment of mobile computing units on the network can be facilitated in a secure manner with just enough information to access the network (210).

    摘要： Laser power control arrangements interrupt power to a laser used in electro-optical readers upon detection of an over-power condition not conforming to preestablished regulatory standards. In one embodiment, during an operational mode, a difference between laser drive currents at two operating points is compared to a difference between laser drive currents at the same two operating points during a calibration mode. The over-power condition is recognized when the difference during the operational mode exceeds the difference during the calibration mode by a predetermined amount. In another embodiment, the laser is only energized to emit the beam at a reduced power level well below regulatory standards for staring at even if a motor drive failed.

    摘要： Described is a method which compares a plurality of wireless protocols utilized on a radio frequency channel. Each wireless protocol utilizes a corresponding predetermined number of subcarrier frequencies on the channel. A number is generated as a function of a comparison of the corresponding predetermined numbers. The frequency channel is divided by the number to generate a set of subcarrier frequencies. Each of the wireless protocols is assigned to a corresponding subset of subcarrier frequencies. Wireless communications are conducted over each subset of subcarrier frequencies utilizing the corresponding wireless protocol during a same time period.

    摘要： An access port (208, 210) for use in a wireless network (200) having a wireless switch (204) in accordance with an exemplary embodiment of the present invention is provided. The access port (300) includes a transceiver (306) operable to send data based on routing information generated by the wireless switch (204). An antenna selector (308) couples the transceiver and a plurality of antennas (310 - 316). The antenna selector is configured to selectively couple the transceiver (306) with at least one of the plurality of antennas based at least in part on the routing information.
