摘要： An oral care implement (1) comprising: an electrode pair with an impedance formed therebetween when electrified; a frequency generator, electrically connected to the electrode pair, for applying a voltage with at least two different frequencies between the electrode pair; an impedance measurement unit, electrically coupled to the electrode pair, for measuring impedance values between the electrode pair at least at the different frequencies; and a contact determination unit, in communication with the impedance measurement unit, wherein the contact determination unit comprises a memory for storing a function, wherein the function correlates impedance values of a defined oral area at the different frequencies, and wherein the contact determination unit comprises a processor for processing the measured impedance values to the stored function so as to determine contact information of the electrode pair with the defined oral area.

摘要： A fastenable device includes a housing having a base portion, a head portion opposite to the base portion, and a body portion between the base portion and the head portion. The base portion has a first fastener in the form of a full ring integral to the housing and defining a through-hole. The head portion has a second fastener in the form of an open ring integral to the housing and defining a snappable recess. The device includes a frequency generator housed in the housing and electrically connected to an electrode pair disposed on the housing, for applying a voltage with at least two different frequencies between the electrodes.
