Abstract: Association request messages received by one or more access points of a wireless local area network are used to infer the location of a mobile unit requesting association. Association may be refused for security purposed if it is determined that the mobile unit is not within an area services by the wireless network. In addition the inferred location can be used to assign the mobile unit to an access point for association.

Abstract: A barcode reader having a light source illuminating a barcode, a diffuser disposed between the light source and the barcode, a camera opening at least partially surrounded by the diffuser, light reflected from the barcode passing through the camera opening and a camera oriented to acquire light reflected from the barcode after passing through the diffuser from the light source.

Abstract: Methods, systems, and apparatuses for RFID devices, such as tag test methods, are described. A tag of a strip of tags is positioned adjacent to an opening in an electrically conductive sheet, the tag having first and second orthogonally polarized antennas. A first RF test signal is transmitted through the opening to test the first antenna of the tag. The tag is positioned such that the first RF test signal has a polarization substantially the same as the first antenna and substantially orthogonal to a polarization of the second antenna. A second RF test signal is transmitted through the opening to test the second antenna of the tag. The tag is positioned such that the second RF test signal has a polarization substantially the same as the second antenna and substantially orthogonal to the polarization of the first antenna. If proper responses to both of the first and second RF test signals are received, the tag has passed the test. This test may be repeated for further tags in the strip of tags as desired.

Abstract: A wireless local area network system allows policy enforcement execution to be split between an access port and a centralized wireless controller. The policy may be of various types, including, but not limited to, a firewall policy, a QoS policy, a traffic shaping policy, and a bandwidth-management policy. On the AP, for all the traffic that is to be bridged or forwarded to specified ports, the policy table on the AP is checked. If it matches the policy table entry, then the specified action is taken. For all the traffic that gets forwarded to the controller by the AP, the match is checked with the policy table at the controller. If a match is detected, then the appropriate action specified by the policy is taken.

Abstract: An imaging scanner with a two dimensional array of sensors analyzes data from a segment of the array to detect if one or more indicia conditions is present that would prevent a successful decode based on data in the segment. In this manner, if decoding the indicia using data from the segment of array data is not possible, an enlarged frame of array data can be sought for decode when necessary while one-dimensional and simple two-dimensional barcodes can be quickly processed by loading and decoding only the segment of the array.

By reducing number of openings into the housing, a risk of liquid or particulate contaminants entering into the device and degrading performance of the mobile computing unit can be reduced and reliability increased.

Abstract: A system and method is provided that provides a mobile communication device with the ability to quickly reestablish a communication session with another after the communication device is awaken from a sleep or idle mode. The mobile communication device is provided with a first power system for powering a central operating system and a second power system for powering a communication system. A mobile communication device establishes a communication session with another communication device by establishing a connection and establishing a communication session.
