Abstract: An interface which effects communication between first and second systems and includes a first arrangement for communicating with the first system using a first protocol and a second arrangement for communicating with the second system using a second protocol. At least one of the arrangements includes a mechanism for effecting wireless communication. In accordance with the invention, a third arrangement is included for translating data received from the first system in accordance with the first protocol into data adapted for the second system in accordance with the second protocol. In the illustrative embodiment, the inventive interface further includes an arrangement for translating data received from the second system in accordance with the second protocol into data adapted for the first system in accordance with the first protocol.

Abstract: A method and system for improving a level of service between wireless devices. Handheld devices implementing the Bluetooth specification typically have relatively limited transmission ranges. As a result, and since they are typically portable, such devices easily experience abrupt communication interruptions, either between themselves and other handheld devices, or between themselves and fixed devices. The effective range of the devices can be extended by providing additional error-correcting coding. Although this modification also results in an extended transmission time, users are provided with an increased transmission range, and are given warning that service may soon be interrupted. Users may then, if they wish, take such steps as finishing their communication or moving into their devices' normal transmission range. Additionally, the handheld devices may use the extra transmission time and range to search for a forwarding path to a recipient device, thus minimizing or preventing any service interruption.

Abstract: A data communication system capable of forwarding IP-addressed data to devices as such devices move among networks having different IP addresses is dislcosed herein. The system includes first and second networks containing first and second pluralities of nodes. At least one of the first plurality of nodes is adapted to receive data transmissions from an external IP-based network. Upon joining the first network, this device is assigned an IP address which remains with it irrespective of whether it moves beyond the range of the first network. When this device roams into the vicinity of the second network, data addressed to the device which is received at the first network is forwarded via at least one node of the second network to the roaming device.

Abstract: A method for operating in a network that includes one or more of the following: assigning a respective active member address to each of a plurality of first slave nodes participating in a piconet; receiving a request to join the piconet; determining that no more different active member address are available in the piconet; determining that a second slave node supports extended addressing; and performing calculations as a function of the bandwidth requirements of the second slave node to determine whether to share an assigned active member address with the second slave node.

Abstract: Methods and systems to determine the position of objects indoors or in confined areas are disclosed. A multitude of broadcast stations are transmitting an omni-directional reference signal and directional signals having each a phase-shift depending upon their specific direction. The objects whose positions are to be identified have a transponder and a means to measure the phase-shift between the omni-directional reference signal and a directional signal received. The measured time-difference indicating the relative direction to the broadcast station, which has sent the directional signal, is sent back to the broadcast station. The absolute position of the object can be determined by the results of an angular measurement of a second broadcast station. The broadcast stations can communicate amongst each other. A post-processing unit can initiate actions according to the position of an object identified.

Abstract: An implementation of a signaling protocol for low power and large scale wireless networks provides a media access control (MAC) that produces a low rate two-way communication link between a commercial infrastructure and a very large number of small, low-cost devices known as electronic tags. The numerous tags attached to merchandise or shelves communicate with a number of access points (AP) distributed throughout a facility containing merchandise for sale or storage. A store controller maintains the pricing database for the point of sale (POS) registers of the facility. Price changes are transmitted in real time to the tag, thus updating the merchandise tags and the point of sales (POS) registers simultaneously. The tags contain a controller and a battery in which conservation of power is crucial to the life of the tags.
