摘要： The power toothbrush includes a brushhead arm (36) and a brush element (38) at a distal end thereof. A V-spring assembly (14) converts the movement of a power drive assembly in a back-and-forth movement. A mounting member (55) at the rear end of the V-spring assembly provides a base for a magnet (56). The back end of the V-spring assembly is displaced in accordance with pressure applied to the brush member. A Hall effect sensor (58) is mounted within the changing magnetic field produced by the magnet as the rear end of the V-spring assembly is displaced due to pressure on the brushhead. A processor (65) is responsive to the output from the Hall sensor and provides an indication when the pressure exceeds a threshold value.

摘要： The adaptive system includes a power toothbrush (10) which determines bristle force or pressure applied by the user against the teeth. The toothbrush includes a processing system (28) for comparing the determined force with a threshold value of excessive force and a threshold adaptive value which is below the excessive force threshold but serves as a warning for the user. The system is capable of raising the initial adaptive value threshold (64) following the user exceeding the adaptive value for a selected number of brushing events and then further for decreasing the adaptive value (66) back toward the initial adaptive value when the increased adaptive value is not exceeded for a selected number of brushing events, thus providing the ability to encourage/coach the user toward a brushing force which is below the threshold adaptive level and into a safe region of operation.

摘要： An actuator (12) for a personal care appliance (10) having an eccentric core (21) to preload the actuator (12) to prevent rattling caused by detrimental reactionary forces. The eccentric core (21) includes a pole assembly (24) radially extending from a spindle (22) having at least a first set (25-1) and a second set (25-2) of pole members. The first set (25-1) has a greater length as measured from the center of the spindle (22) than the second set (24-2), reducing the magnet gap on one side of the spindle (22) to create an eccentric core and preload the actuator (12). Alternatively, the preload can be mechanically created by a set of bearings (28) disposed within housing (18) of the actuator (12), where the bearings (28) have a centerline (A3) offset from the principal axis (A1) of the housing (18).

摘要： A directed jet mouthpiece (10) comprises at least one mouthpiece trough (12,14) configured to fit over a front portion of a dental arch of a user's teeth. The at least one mouthpiece trough includes a buccal-side vertical member (16), a lingual-side vertical member (18) and an occlusal-side horizontal member (20) extending in between. The at least one mouthpiece trough further includes at least one fluidics inlet (22), a plurality of jet orifices (24) on both buccal- and lingual-side vertical members, and at least one fluidics path (26) disposed between the fluidics inlet and jet orifices. A plurality of directed jet orifices (28) is disposed in end regions (30) of the at least one mouthpiece trough. The at least one fluidics path (26) is further disposed between the fluidics inlet and plurality of directed jet orifices. The plurality of directed jet orifices (28) direct fluid jets rearward towards a remainder of teeth in a user's mouth beyond the end regions (30) of the at least one mouthpiece trough.

摘要： A flowable medium distribution device (10) comprises a chamber (12), a distribution member (30), a dispensing membrane (24,40,68,72) and bristles (36). The chamber (12) is configured to contain the flowable medium (62). The distribution member (30) includes an aspect (32,34) from which the flowable medium is to be dispensed. The dispensing membrane (24,40,68,72) is disposed on the aspect of the distribution member for dispensing the flowable medium on at least one surface to be treated. The dispensing membrane comprises a plurality of uni-directional dispensing outlets (26,46,70,74), operable between (a) normally-closed and (b) open positions. The bristles (36) extend from the dispensing membrane and are for contacting with the surface to be treated. The dispensing membrane (i) dispenses the flowable medium through the plurality of unidirectional dispensing outlets only in response to application of a differential pressure across the dispensing membrane equal to or exceeding a threshold, wherein the uni-directional dispensing outlets open for delivery of the flowable medium, and (ii) responsive to the differential pressure across the dispensing membrane being less than the threshold, the uni-directional dispensing outlets return to a normally-closed position which terminates delivery of the flowable medium (62).
