Abstract
A personal care appliance () comprises a handle (), an attachment (), and a controller (). The handle () includes an actuator () and drive shaft (). The attachment () has a body () with a principal axis () extending between a proximal end and a distal end thereof, wherein the proximal end couples to the drive shaft. The attachment () further includes a mass-spring identifiable assembly () having at least one identifiable resonant frequency in response to a given excitation, wherein the at least one identifiable resonant frequency comprises a resonant frequency selected from at least two different resonant frequencies. The controller () is configured to control the attachment (), via the actuator (), over a predefined range of frequencies that includes the given excitation. The controller () is further configured, in at least a detection mode, to uniquely recognize the attachment () via detecting a presence of the at least one identifiable resonant frequency of the mass-spring identifiable assembly () of the attachment () in response to the given excitation.
