SYSTEMS, DEVICES AND METHODS INVOLVING DEVICE IDENTIFICATION
First Claim
1. A system for device identification comprising:
- a first device having a first power line and a first connector, the first connector being coupled to the first power line; and
a second device having a second power line and a second connector, the second connector being coupled to the second power line and sized and shaped to mate with the first connector such that the first device electrically communicates with the second device;
the first device being operative to modulate impedance exhibited at the first power line;
the second device being operative to detect the modulated impedance and correlate the modulated impedance with an identification of the first device.
