The apparatus may also include one or more separation portions situated between the TFS sheet and the first or second sheet to bias the TFS sheet apart from the first or second sheet.
A method and apparatus for determining a range within a wireless communication system is provided herein. The range information can then be used to locate a node (e.g., an asset tag). During operation, the minimum transmission power of a source transceiver (e.g., an RFID reader) that enables a tag to be detected will be used to indicate distance. Changes in transmit power will be used to indicate relative changes in distance to a particular node. The reader will be configured to always operate at a transmission power that will result in a certain percentage (e.g., 50%) detection rate for a target transceiver (e.g., an RFID asset tag). As the reader moves closer to the tag, the minimum detection power will decrease; as it moves farther from the tag, the minimum detection power will increase. This information is displayed to give a general change in range information between the RFID reader and the asset tag (e.g., increasing range or decreasing range). An individual will be able to easily locate the asset tag by using the displayed information.
Automatic Security Compliance Assessment (ASCA) systems and methods are provided for automatically generating and determining a security rating for a plurality of Settings Objects (SOs), where each of the SOs define particular configurations of subsystems of a wireless computing device. Each SO collectively defines a collection of Values specified for Configurable Attributes that can be used to define a different configuration for a particular subsystem associated with a particular Setting Class that is used to guide the creation of that particular SO. The server can store a group of security rating templates, each of which includes the information needed to determine an expected security rating for any SOs created per a particular Settings Class. For any combination of device settings, the resultant SOs can be used to generate an expected security rating.
A multi-context mobile unit includes a processor, a user interface coupled to the processor and configured to ac-cept user input, a storage component coupled to the processor, and an input/output module coupled to the processor and config-ured to interact with at least one external network, wherein the processor is configured to selectively execute a plurality of virtual devices stored within the storage component in response to the user input, and wherein the plurality of virtual devices includes a first virtual device and a second virtual device having separate and isolated data access.

FREQUENCY SELECTIVE SURFACE AIDS TO THE OPERATION OF RFID PRODUCTS
The present invention is directed to systems that use frequency selective surfaces (FSS) to aid in the operation of radio frequency identification (RFID) devices and products. In one embodiment, a system for interrogating radio frequency identification (RFID) tags includes a conveyor belt and a RFID reader. The conveyor belt has a first surface and a second surface. The first surface is configured to receive an item in which an RFID tag is affixed and the second surface is configured to slide on a metal slide plate. The RFID reader is configured to transmit instructions embodied in a radio frequency (RF) signal to the RFID tag, wherein the metal slide plate is positioned between the RFID reader and the RFID tag and comprises a frequency selective surface that is substantially transparent to the RF signal.
H01Q 1/42 - Housings not intimately mechanically associated with radiating elements, e.g. radome
H01Q 3/44 - Arrangements for changing or varying the orientation or the shape of the directional pattern of the waves radiated from an antenna or antenna system varying the electric or magnetic characteristics of reflecting, refracting, or diffracting devices associated with the radiating element
H01Q 15/02 - Refracting or diffracting devices, e.g. lens, prism
Described is a method which includes receiving a selection of an application type (210), selecting a power management class (215) as a function of the application type and adjusting resources of a mobile unit (220) as a function of the power management class.
