Abstract: An earpiece includes an earpiece housing, an intelligent control disposed within the ear piece housing, at least one audio input sensor operatively connected to the intelligent control, a transceiver operatively connected to the intelligent control, and a user interface operatively connected to the intelligent control and configured for receiving user input. The intelligent control is configured to receive voice input through the at least one audio input sensor and interpret the voice input to determine a voice command from a set of voice commands.

Abstract: A dental floss device includes a handle having a head piece and a disposable holder for a length of dental floss. The holder includes a base portion and a pair of spaced-apart jaws extending from the base and which extend to embrace the head piece of the handle when the holder is in a correct alignment configuration with respect to the handle. The device has an interlock which ensures that the holder can be interengaged with the head piece only when the holder is correctly aligned with the head piece. The interlock includes a head interlock part provided by interlock grooves and a holder interlock part provided by corresponding interlock tongues. There are two interlock grooves and corresponding interlock tongues which slidably interengage when the holder is correctly aligned with the head piece If the holder is turned so that it is not correctly aligned with the head piece, the interlock tongues of the holder prevent engagement of the holder with the head piece.

Abstract: A dental floss device 1 comprises a handle 2 having a head piece 3 and a disposable holder 4 for a length of dental floss 5. The holder 4 comprises a base portion 20 and a pair of spaced-apart jaws 21 extending from the base and which extend to embrace the head piece 3 of the handle 2 when the holder 4 is in a correct alignment configuration with respect to the handle 2. The device has an interlock which ensures that the holder 4 can be interengaged with the head piece 3 only when the holder 4 is correctly aligned with the head piece 3. The interlock comprises a head interlock part provided by interlock grooves 10 and a holder interlock part provided by corresponding interlock tongues 11. There are two interlock grooves 10 and corresponding interlock tongues 11 which slidably interengage when the holder 4 is correctly aligned with the head piece 3.
