The Snyderphonics Manta controller is a USB touch controller for music and video. It features 48 capacitive touch sensors, arranged in a hexagonal grid, with bi-color LEDs that are programmable from the computer. The sensors send continuous data proportional to surface area touched, and a velocitydetection algorithm has been implemented to estimate attack velocity based on this touch data. In a...

In this paper, we propose a novel SDN-based cellular network architecture that will be able to utilize the opportunities of centralized administration of today’s emerging mobile network. Our proposed architecture would not depend on a single controller, rather it divides the whole cellular area into clusters, and each cluster is controlled by a separate controller. A number of controller servic...
