With audio data reduction on the basis of ISOIEC standard 11172-3, a frame length varying by 8 bits is used at a sampling frequency of 44. The present invention collects a plurality of metrics for each host that it is aware of in a P2P network, most often by a host information or query hit message. An electrical current is applied to the resistive ink layer, and when the force of impact from the projectile acts upon the sensor layer a change in impedance is measured via standard circuits and electronics.
