1. A stud miss indicator system for a fastener driving tool, the stud miss indicator system comprising:
- at least one sensor electronically connected to the fastener driving tool and physically connected to the fastener driving tool at a location that enables the at least one sensor to sense and generate at least one electrical sensor output signal based on impact forces generated by a fastener driving operation of the fastener driving tool, the fastener driving operation including applying an impact force along a longitudinal axis of a fastener; and
a processor communicatively connected to said at least one sensor to receive the at least one electrical sensor output signal, the processor configured to;
(1) evaluate the at least one electrical sensor output signal to distinguish between an improperly driven fastener and a properly driven fastener;
(2) if a fastener was properly driven during the fastener driving operation, generate a first electrical processor output signal, and send the first electrical processor output signal to an indicating device to control the indicating device to output a first indication; and
(3) if the fastener was improperly driven during the fastener driving operation, generate a second electrical processor output signal, and send the second electrical processor output signal to the indicating device to control the indicating device to output a second indication different from the first indication, wherein the second indication comprises two or more of an audible output, a visual output, and a vibratory output, and wherein the fastener driving tool is operative regardless of whether the fastener was improperly driven or properly driven.
