Systems, devices and methods involving device identification
First Claim
1. A system for device identification comprising:
- an accessory having a first power line and a first connector, the first connector being coupled to the first power line; and
a mobile 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 accessory electrically communicates with the mobile device;
wherein the accessory is operative to modulate impedance exhibited at the first power line in response to communication initiated by the mobile device, the mobile device being operative to initiate the communication with the accessory by providing oscillations to the accessory via a signal path established by coupling of the first connector and the second connector, the oscillations from the mobile device providing power to the accessory to modulate the impedance exhibited at the first power line;
the mobile device having a signal conditioner electrically communicating with the second power line and being operative to isolate the modulated impedance from the oscillations such that the mobile device is operative to detect the modulated impedance and correlate the modulated impedance with an identification of the accessory;
the mobile device being operative to selectively alter a mode of operation of the mobile device based, at least in part, on the identification of the accessory correlated from the detected modulated impedance;
the accessory having a temperature sensor and being operative to alter the modulated impedance to encode information corresponding to a sensed temperature onto the modulated impedance and communicate the information to the mobile device; and
the mobile device being operative to selectively alter the mode of operation of the mobile device based, at least in part, on the information encoded onto the altered modulated impedance.

8. A method for device identification comprising:
-
coupling a first connector of a first device with a second connector of a second device to form a signal path therebetween; initiating communication between the first device and the second device by propagating oscillations along the signal path from the first device to the second device, wherein the second device applies an impedance modulation to the signal path in response to the oscillations; detecting, with the first device, the impedance modulation attributable to the second device by isolating the impedance modulations from the oscillations; correlating, by the first device, the impedance modulation with predefined impedance modulations such that an identification of the second device is determined; selectively altering a mode of operation of the first device based, at least in part, on the identification of the second device; altering, by the second device, the modulated impedance to communicate a sensed temperature condition of the second device to the first device such that the sensed temperature condition is encoded into the modulated impedance altered by the second device; and selectively altering the mode of operation of the first device based, at least in part, on the modulated impedance altered by the second device. - View Dependent Claims (9, 10, 11)
