Abstract: A method and system to control power transmission between two Near Field Communication (NFC) devices with and without data transfer using NFC technology are provided. The method includes transferring at least a portion of power between two NFC devices using different RF signals and appropriate NFC Transceivers. The method controls the power transmission between two NFC devices by proposed changes in NFC Digital Protocol, LLCP (Logical Link Control Protocol) and in the application flow control.

Abstract: Methods and devices provide a wireless communications hub device and services enabling remote access to electronic medical or fitness devices in a manner that simplifies device networking A wireless communication hub device may include a processor and wireless communication transceivers configured to connect to cellular and/or WiFi networks to access a remote server, and wired and/or wireless local networks for connecting to electronic medical or fitness devices. The wireless communication hub device may plug into a power source, connect to an electronic medical or fitness device, and communicate via a second wireless network with an associated server-based service. The system enables discovery of the wireless communication hub device and connected electronic medical or fitness devices.

Abstract: Some embodiments teach an apparatus for determining a proximity of one or more first Bluetooth devices. The apparatus can include: (a) at least one Bluetooth base station with (1) a Bluetooth transmitter configured to transmit one or more service discovery requests to the one or more first Bluetooth devices; and (2) a Bluetooth receiver configured to receive one or more responses from the one or more first Bluetooth devices to the one or more service discovery requests; and (b) a computational module configured to run on one or more processors and further configured to determine one or more approximate distances between the at least one Bluetooth base station and the one or more first Bluetooth devices based on the one or more responses from the one or more first Bluetooth devices. Other embodiments are disclosed.
