Merely by way of example, some systems can be configured to determine whether to use a VoIP system or a cellular system to handle a particular call, and/or to transition a call from one network to the other network. Other systems can be configured to substitute a public number (which might be, for example, a VoIP number) for a private number (which might be, for example, a cellular number) when routing a call originating from a dual-mode phone on a cellular network. Further systems can be configured to allow a VoIP system to serve as an anchor for calls originated and/or delivered on a cellular system, for instance to facilitate a transition between cellular and VoIP service during a call.

Abstract: A method can be used for detecting a potential presence of an object by a reader capable of mutually communicating via a contactless communications protocol. An antenna of the reader transmits a magnetic field on a carrier signal having a sub-carrier modulated by a first data sequence. The modulated sub-carrier is non-interpretable by the object. The antenna of the reader receives a signal resulting from the transmission. The reader demodulates the sub-carrier of the resulting signal so as to extract a second data sequence from the resulting signal. The first data sequence and second data sequence are correlated and the potential presence or absence of the object is determined based upon the result of the correlating.

Abstract: Using inductive currents to wirelessly charge a device via a device connected to a power source. This inductive charging may result when a first mobile device recognizes a second mobile device via a wireless connection (e.g., Bluetooth, Bluetooth Low Energy (BLE), Near-Field Communication (NFC), or the like). An application stored on the first mobile device may recognize a second mobile device by transmitting an advertising packet when the first mobile device is connected to a power source. An advertising packet may be received by the second mobile device and the second mobile device may transmit a response to the advertising packet in order to generate a connection between the first and second mobile devices. The response may include data such as, connection strength, response time, connection preferences, and the like. Upon detection and connection, the second mobile device may be wirelessly charged by the first device via inductive charging.
