A multipurpose toothbrush that has a handle, toothpaste reservoir, button, a toothpaste hole, a tube, a head, a head cover, a tongue scraper, one or more legs, a floss compartment, and an indicator light. The toothpaste reservoir is fluidly connected to the toothpaste hole on the toothbrush head, and the button is operatively connected to the toothpaste reservoir. When the button is pushed upwards, the entire reservoir is forced upwards, and toothpaste is pushed through a tube, exiting the brush holes. The head cover may fold over the brush head when the brush is stored, and may fold into an indent on the toothbrush head when the brush is being used. The legs support the brush so that the brush may stand upright when not in use. The toothbrush head may detach freely from the handle to be cleaned or replaced.

A toothbrush configured to dispense toothpaste and dental floss, the toothbrush having a handle, a head, and a chamber defined by the handle and the head into which toothpaste can be inserted directly or in a tube. The head of the toothbrush defines a hole and the handle is configured to dispense the toothpaste through the hole and onto bristles on the head of the toothbrush. A cap can be provided to cover the bristles. The cap can also include a spike that is used to puncture a hole in a tube of toothpaste or to plug the hole when not in use.

A removable toothbrush head for an electric toothbrush includes a bristle carrier and an elongated neck. One end portion of the elongated neck includes an opening for connection to an electric toothbrush handle, and another end portion comprises a neck hub configured to rotatably support the bristle carrier. Also included is a driven brush shaft disposed longitudinally within the elongated neck. The brush shaft is configured to interact with the bristle carrier at a distal end portion of the brush shaft, which includes a pivot extension extending therefrom and spaced apart from the longitudinal axis of the brush shaft, as well as a bristle carrier interface positioned at least partially along the longitudinal axis of the brush shaft and configured to cause partial rotational motion of the bristle carrier when the brush shaft is driven by an electric toothbrush handle.

A system for classifying the usage of a handheld consumer device having a sensor and an analyzer. The sensor determines usage data at successive time instants and provides a temporally successive sequence of usage data during a usage session. The analyzer classifies the usage of the device with respect to at least one set usage classes and assembles a temporally successive sequence of input tuples of usage data relating to a predetermined time period of the usage session, each of the input tuples having at least one element representing the usage data at the respective time instant and for inputting the sequence of input tuples into at least one artificial neural network arranged to output at least one output tuple comprising a number of elements in accordance with the number of usage classes, each element of the output tuple representing a prediction value that the usage of the consumer device at the given time instant relates to a respective usage class.

An apparatus for classifying the motion of a movable treatment device having at least one inertial sensor, a motion pattern classification device configured to discriminate between two or more motion classes contained in a set of motion classes of the movable treatment device, and an interface for providing inertial sensor data from the inertial sensor to the motion pattern classification device. The inertial sensor data represents a movement of the movable treatment device, wherein the motion pattern classification device comprises at least one neural network configured to receive and classify the inertial sensor data with respect to the motion classes contained, each associated with at least one class member selected based on the motion of the movable treatment device.

A method and an apparatus for performing a localization of a movable treatment device having an inertial sensor and configured to treat a target surface. A motion pattern recognition device discriminates between two or more motion patterns contained in a set of motion patterns. An interface provides at least one inertial sensor data from the inertial sensor to the motion pattern recognition device. At least one inertial sensor data represents a movement of the movable treatment device. A neural network is configured to receive the at least one inertial sensor data and to map the at least one inertial sensor data to at least one motion pattern contained in the set of motion patterns associated with one or more different zones of the target surface so that the mapping of the at least one inertial sensor data with the at least one motion pattern indicates an estimation of the location of the device with respect to at least one zone of the target surface.

A dental cleaning tool includes a body portion defining a longitudinal axis of the dental cleaning tool. The body portion includes a floss assembly including a first arm and a second arm extending substantially perpendicularly relative to the longitudinal axis, a receiving slot formed in the first arm, and a shield formed on the first arm. The shield is configured to cover the receiving slot such that access to the receiving slot is restricted from a first direction. The tool also includes a secondary cleaning tool coupled to the first arm. The secondary cleaning tool is pivotable relative to the first arm in at least two degrees of freedom such that the secondary cleaning tool is insertable into the receiving slot from a second direction different than the first direction.

In one embodiment, a dental flosser includes a handle and a housing coupled to the handle. The housing includes a chamber for rotatably receiving a spool having first top and bottom surfaces and a side surface and having a supply of floss wound about the side surface, the supply of floss having second top and bottom surfaces. The housing further includes a floss orifice for directing at least a portion of the supply of floss therethrough. The dental flosser also includes an actuator including at least one contact surface configured to frictionally engage at least one of the first top surface, the first bottom surface, the second top surface, or the second bottom surface. The actuator further includes a biasing member for biasing the at least one contact surface relative to the spool.

An oral hygiene system including a head with a base portion with arms extending to support a sweep and flossing filament. The system may include removeable heads with different configurations directed to different oral environments and uses.
