Abstract: A power-driven toothbrush comprising a brush head 1 mounted on a brush handle 2 for vibratory movement relative thereto, a vibration transmitting arm 33 extending between said handle 2 and said head 1 and a vibration actuator 3 located within the handle 2, said vibration transmitting arm 33 including a magnet 34 located within said handle 2 and the actuator 2 including a solenoid 32 adjacent said magnet 34 and means for supplying AC current to the solenoid 32 a frequency which is the same as the resonant frequency of the vibration transmitting arm 33. The means for supplying AC current to said solenoid includes a printed circuit board 31. The frequency of the AC current delivered to the solenoid and the natural frequency of the vibration transmitting arm are in the range of 100-300 Hz.

Abstract: An electric hand and towel dryer includes an enclosure having an inlet and first, second, and third outlets for heated air. A tube associated with the second and third outlets connects to opposed air outlets in the enclosure. A blower unit incorporates a heating element, a motor, and a fan located inside a first chamber of the enclosure for generating a hot air stream. The stream selectively exits the enclosure through the first outlet or the second and third outlets. A folding blind controls the flow of the hot air through the first or second and third outlets for respectively drying hands or a towel supported on the hanger.
