Abstract: A smart phone companion loop is presented as a phone companion solution that extends the use of a mobile device to the loop tablet or compatible computing device by pairing functionality of both devices. The loop tablet operates as a standalone or parallel device, allowing user to operate applications and functionality from either of the paired devices. The loop tablet allows users to view smart phone applications on a larger screen setting wirelessly. Loop connectivity is the seamless integration of one or more paired mobile devices that communicate wirelessly and share total functionality when tethered or synced with bi-directional control and interface between looped devices with functional commands from both devices. Tablet and Cell phone will be ‘paired’ for security reasons. It may be possible to pair a tablet, car or computing device with multiple or more registered phones that operates under a standard or custom operating system.
