摘要： The toothbrush includes a handle portion which includes a power drive system (14) and further includes a brushhead assembly (20), which includes a brushhead arm having a brush element (21) at a distal end thereof A drive train assembly (12) is responsive to a drive signal from the power assembly for converting the action of the power assembly to a motion of the brushhead assembly. A magnet (30) is secured to the rear of the drive train, with a Hall effect sensor (32) mounted within the magnetic field produced by the magnet as the toothbrush moves in operation. Pressure on the brush element produces a phase shift of the Hall sensor output. A processor (15) determines the value of the phase shift of the Hall sensor signal as pressure is applied to the brush member and produces a signal indicative of the pressure applied by using stored information (71) which relates phase shift to pressure for the particular appliance.

摘要： A powered toothbrush apparatus with capacitive touch control, which includes a head portion having an oscillating tuft block driven by a motor, a handle portion, and an elastically deformable capacitive touch control panel mounted in the handle portion. In one embodiment, the control panel includes movable sensor targets each paired with a corresponding capacitance sensor electrically connected to a programmable microprocessor. Applying finger pressure on the control panel adjacent a sensor target operates to change the capacitance of the respective sensor target-sensor pair. The microprocessor detects the change in capacitance, which may be used to control the motor speed for changing the oscillation rate of the tuft block. In one embodiment, a linear array of sensor targets-sensors is provided which is activated by a sliding finger or thumb motion across the array. A related operating method is disclosed.

摘要： The appliance includes a body (12) which includes a tank (22) for liquid. A pump/regulator assembly (18, 20) maintains pressure in the tank in the range of 70-120 psi. A valve, timer and controller (30, 31, 37) controls sequential bursts of liquid, with each burst having a duration of 0.02-2 seconds, with the total amount of liquid in a single cleansing event being less approximately 0.2 ml or less. A firing rate is such that successive bursts of liquid are separated by a controlled time when there is no liquid delivery.

摘要： An electric toothbrush is disclosed. The electric toothbrush according to some example embodiments includes a bristle-vibrating unit that vibrates toothbrush bristles to clean a side of teeth in contact with the toothbrush bristles, a bristle direction-sensing unit detecting a direction to which the toothbrush bristles are directed in an oral cavity and a control unit automatically controlling the bristle-vibrating unit in response to the detected direction such that the vibration intensity of the toothbrush bristles when an occlusal side is brushed is weaker than the vibration intensity when a buccal side or a lingual side is brushed.
