US Patent 7086298 Apparatus and method for identifying bowstring force characteristics

An apparatus includes a base structure, a force measuring device, and a processing device. The force measuring device is operatively connected between a bowstring connector and a force transmitting connection to the base structure, and is adapted to produce a force output signal indicative of the tensile force applied along a draw force axis between the bowstring connector and the base structure. The processing device is mounted on the base structure and uses the force output signal received from the force measuring device to identify one or more bowstring force characteristics from the force output signal produced over the course of the bowstring draw cycle.
