Abstract: A formula delivery system can be used in conjunction with hair and scalp treatment appliances to supply a hair treatment formulation to the appliance. In one aspect, the formula delivery system delivers hair coloring formulation to the appliance. Formula delivery systems of the present disclosure generally include at least one fluid container configured to retain a volume of formulation for delivery of the formulation to a hair coloring appliance. In this regard, the formula delivery system may be configured to removably couple to an inlet member of the appliance that allows the appliance to draw the formulation from the fluid container for use within the appliance.

Abstract: A formula delivery appliance generally includes a formula delivery head having features to mix, direct, and distribute formulation through nozzles to a desired location, such as the hair or scalp of a user. In this regard, the formula delivery head may include a plurality of nozzles configured to discharge the formulation at a desired flow rate. In some instances, the flow rate across the plurality of nozzles is controlled such that each nozzle has a flow rate within a specified percentage of the average flow rate across the plurality of nozzles.

Abstract: A formula delivery appliance can be used for treatment of the hair and scalp, such as an appliance used to color hair. The appliance may include a consumable assembly incorporating various components of the hair and scalp treatment appliance, a portion of which may be consumed and then replaced by a user. In this regard, the consumable assembly may include one or more formulation delivery packets, nozzles, manifold chambers, distribution protrusions, and the like. The hair treatment appliance may also include a rotatable coupling having a driven gear and a drive gear, where the driven gear may selectively engage the drive gear. In another aspect, the hair treatment appliance may also include a fluid container to retain a volume of formulation for delivery to the appliance.

Abstract: Various operational mode arrangements of an electric toothbrush (10) include pre-programming a controller portion (16) of the electric toothbrush such that a single brushing event of approximately two minutes comprises automatically at least two different operating modes and specified times for each mode. Another operational mode includes the capability of operating the on/off button (20) of the toothbrush within a specified short time following termination of a normal brushing event to provide the user a specified additional time, e.g. 30 seconds of toothbrush action. A special toothbrush interface arrangement includes a display (80) which encourages children to maintain brushing for the full brushing period. This is accomplished through sequential illustration of the progress of an article from an initial state to a final desired state as the toothbrush is used for increasing portions of a full brushing time period.

Abstract: Formula delivery devices include a handle and a consumable assembly. The handle has a handle shell, and the consumable assembly is configured to be removably joined with the handle by insertion into the handle shell. The consumable assembly has a formulation container disposed in an elongate housing and is configured to contain a volume of a formulation. The formulation container is provided with a sealing member configured to enable fluid communication with the formulation container.

Abstract: A drive shaft coupling is provided, such as a coupling used with a formula delivery appliance. The drive shaft coupling generally includes a drive gear and a driven gear, with one of the drive gear and driven gear having a biasing member to allow axial translation. The drive shaft coupling is generally configured to transfer rotation from the drive gear to the driven gear. In one aspect, the drive shaft coupling is capable of alignment and coupling of the drive gear and driven gear upon the radial sliding of the coupling from a non-engagement position to an engagement position.

Abstract: A workpiece, such as a treatment workpiece, for use with a non-powered appliance is disclosed. The workpiece includes a rechargeable or non-rechargeable battery integrated into the workpiece housing. The workpiece in some examples can be configured such that the battery is neither removable nor replaceable. The capacity of the battery can either be selected so as to provide at least a single use of the workpiece or to correspond to the recommended replacement period (e.g., 90 days) of the workpiece.

Abstract: Treatment protocols for preparing a subject's skin to receive skin formulations having one or more active materials are provided. The devices and/or methods for carrying out the treatment protocols aim to increase the skin's ability for skin formulations to penetrate or infuse into the SC layers thereof. The treatment protocol includes the application of shearing forces in order to part, tear, or form fissures only in the Stratum Corneum (SC) of the subject's skin without inducing trauma in viable skin layers below the SC. After application of shearing forces to the skin, a skin formulation can be applied to the sheared areas of skin.

Abstract: An applicator includes a roller, a treatment composition component, a cutaneous measurement component, and a controller. The roller contacts a portion of skin at a contact location and subsequently a target location. The treatment composition component selectively deposits a composition on a roller surface at a deposition location that is on the roller surface a circumferential distance away from the contact location. The cutaneous measurement component generates one or more parameters associated with the target location on the portion of skin. The target location is a target distance from the contact location that is equal to or greater than the circumferential distance. The controller controls the treatment composition component to selectively deposit the treatment composition on the roller surface in response to the one or more parameters associated with the target location on the portion of skin generated by the cutaneous measurement component.

Abstract: An applicator for treating skin conditions includes at least one treatment composition component and a discontinuity identification component. The at least one treatment composition component is configured to selectively deposit a treatment composition at a deposit location on the portion of skin. The discontinuity identification component is operably coupled to an electromagnetic energy detector. The discontinuity identification component includes circuitry configured to monitor a level of the one or more parameters as the applicator traverses the portion of skin and to control the at least one treatment composition component to selectively deposit the treatment composition to the deposit location on the portion of skin based on one or more inputs indicative of a decrease in reflection of an electromagnetic energy interrogation stimulus from the portion of skin at the deposit location.

Abstract: An applicator includes a discontinuity identification component and at least one treatment composition component.
