International Classification

H04B 7/00

U.S. Classification

455 412, 4551275, 455574

Abstract

A method, apparatus, and system for tracking and locating Bluetooth enabled devices is described. A network of Bluetooth sniffers can be used to rapidly locate lost devices and their owners. Wearable child devices maintain low power contact with parent devices until such time as a signal limit is reached, at which point the parent devices alarm. An optional network of fixed sniffing devices can be used to coordinate a search for lost child devices once an alert is issued to the system.

Abstract

Aspects of a method and system for advertising a Bluetooth multicast feature are provided. A master device may provide a multicast service to active slave devices during a Bluetooth piconet connection. A Bluetooth multicast packet addressed to a specific slave device may be transmitted over a point-to-point connection. The multicast packet may be decoded and acknowledged by each of the slave devices on the piconet. The master device may re-transmit the multicast packet addressed to the specific slave device over the same point-to-point connection when an acknowledgment or response indicating a reception of the multicast packet from each of active slave devices may not be detected. The point-to-point connection may be associated with a L2CAP channel identified by a determined unique channel identifier (M-CID). The point- to-point connection may be secured by assigning a common authentication key shared among the slaves of the piconet.

Abstract

Systems and methods for determining whether a companion communication device is beyond a proximity of a primary communication device are provided. In some aspects, a system includes an analysis module configured to determine whether a wireless transaction between the primary communication device and the companion communication device is at a conclusion. The system also includes a communications module configured to emit a sensing signal based on the determination of whether the transaction is at the conclusion. The sensing signal is insufficient to elicit a response from the companion communication device. The system also includes a detection module configured to detect a present parameter associated with the emitted sensing signal. The analysis module is configured to determine a parameter change between the present parameter and a reference parameter, and to determine whether the companion communication device is beyond the proximity of the primary communication device based on the parameter change.

Abstract

A near field communications (NFC) device is disclosed that interacts with other NFC devices to exchange information and/or the data. The NFC device can include a plurality of secure elements each configured to store one or more card emulation instances. Each card emulation instance is associated with an application identification (AID) and a priority value. The NFC device can route communications between another NFC device and plurality of secure elements based on each card emulation instance's associated AID and priority value.
