Abstract: A mobile device for data communications has a radio circuit for data communications with a wireless network access point and a radio tag for transmitting location-identifying radio signals. The radio circuit and the radio tag are co-located on a circuit board or are commonly powered. The operation of the radio circuit and the radio tag are segregated in time to avoid interference. Standard wireless network interface protocol functions are exploited to identify time intervals in which the radio circuit is inactive for data communications. These time intervals are used to operate the radio tag to transmit the location-identifying radio signals.

Abstract: An apparatus for interfacing a wireless local area network with a wide area, cellular or public switched telephone network including the function of a wireless LAN base station or access point, and a gateway. The interface may contain one or more different types of gateways, including a PSTN voice gateway, an analog modem gateway, and others. The apparatus may also include a well designed to receive the handset or mobile computer device to recharge the battery as well as to automatically transfer data when the phone or device is secured in the well.

Abstract: A product location information retrieval system for use by a customer in a retail establishment including a computer terminal with an optical reader arranged to receive a data input query from the customer using the terminal and relating to a product, and a display in the terminal for displaying an image of a product to be accessed by the user.

Abstract: A wireless communications network includes a reconfigurable array of access points for linking wireless devices in an infrastructure mode. One or more of the access points are mobile. The mobile access points in the network can be repositioned to change the geographic distribution of the bandwidth coverage provided by the wireless network. The mobile access points may be repositioned to redistribute available network bandwidth heterogeneously according to the demand for bandwidth in local areas and to meet quality of service standards.

Abstract: Real time location system functionality is provided in conjunction with bar codes and other coded information devices to provide location information in transaction processing systems. A system and method of the present invention may be used to track the location of objects which are coupled to coded information devices.

Abstract: Described are a system and method for a wireless network security. The system may include a wireless electronic device and a wireless access point. The access point includes a memory and is capable of wirelessly communicating with the device. The memory stores an access scheme which defines an authentication procedure for allowing the wireless communications between the electronic device and the further asset. The authentication procedure utilizes data as defined by the access scheme. The access point is situated in a location accessible to an authorized user and provides access for the electronic device to a further asset. The access point allows the wireless communications between the electronic device and the further asset only when the authentication procedure is successful. Before the authentication procedure, the data is transferred between the device and the access point via a physical access to at least one of the access point and the electronic device.

Abstract: A system and method is provided for providing enriched content over a wireless network to a mobile device based on location information read by the mobile device from a location information storage device. The location information storage device may be a bar code, RFID tag, Infobutton, or any other device which may be affixed to a fixed location and which may store unique location information to be read by the mobile device.

Abstract: A system utilizes radio frequency identification (RFID) technology to determine the precise location of assets within a large area or building. RFID tags are attached to the assets. A mobile RFID portal, which includes an RFID tag reader, is moved along a select path through the large area or building to read information from RFID tags present in the vicinity of the path. The mobile RFID portal may be moved along the floor or on an overhead rail. The RFID tag information is analyzed along with data on the positions of the mobile RFID portal along the path and/or data on the times-of-read to determine the location of assets associated with the read RFID tags.

Abstract: The present invention is useful in connection with calibration of a wireless location system based on RF signals within a facility. Identification devices are provided at fixed locations which are selected within the facility. The RF environment is sampled at selected locations and data representing the sampled RF environment and the corresponding selected location is provided to a computer which maintains a database corrolating the RF environment data and the selected locations to be used with calibrating a location system.

Abstract: An interface chip for a peripheral module connectable to and for use with a host computer is provided which utilizes an static Random access memory (SRAM) within the interface chip for both encryption of data packets and temporary storage of Card Information Structure (CIS) information. The CIS information is stored in the SRAM only during the power-up phase of operation, when encryption of data packets is not necessary and thus the memory is not being utilized for that purpose. This precludes the need for a separate SRAM IC, thus saving space on the card.

Abstract: A portable data device system includes a portable data device and a cradle for receiving the portable data device. The cradle is arranged to recharge the portable data device power supply and/or upload or download information to and from the portable data device. The cradle and portable data device are in wireless communication allowing a minimum of processing and data storage capability at the front end and hence operation of the portable data device as a thin client.
