Electronicless accessory recognition using dielectric properties

Abstract

A system including a device including a processor and an electrode configured to sense a dielectric profile, and at least one accessory having a dielectric profile, where the processor is configured to receive the sensed dielectric profile from the electrode, compare the sensed dielectric profile with a profile database, where the profile database includes a plurality of dielectric profiles, and determine an identity of the accessory based on the sensed dielectric profile. Further, a method of determining an identity of an accessory, including receiving a sensed dielectric profile from the accessory with an electrode located on a device, comparing the sensed dielectric profile with a profile database, wherein the profile database includes a plurality of dielectric profiles, and determining an identity of the accessory based on the sensed dielectric profile.
