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 hygiene device includes a toothbrush and a dental floss dispenser. The dental floss is stored in the handle of the dental hygiene device and is wound without a spool to decrease the diameter of the handle and allow the handle to fit within a conventional toothbrush holder. The dental hygiene device can also be used to aid in flossing, eliminating the need to use insert two fingers into a user's mouth in order to floss. After flossing, the floss can be severed by using a floss cutter disposed on the handle of the device.

An oral hygiene device comprising a brush head portion comprising a brush head having a plurality of bristles and a longitudinal extension connecting the brush head to a base portion having an insertable portion, the insertable portion having a smaller diameter than the base portion. A floss dispenser portion having an inner cavity operable to receive a floss coil. The inner cavity extending through an upper end of the floss dispenser portion, operable to receive the insertable portion. An aperture proximal the upper end of the floss dispenser portion, extending through the floss dispenser portion to create a passage through which a length of floss may extend. Additionally, a method of providing oral care, comprising providing the oral hygiene device described above, pulling the length of floss through the aperture, wrapping the length of floss around the cleat, pulling the length of floss through the keyhole slot, and creating tension in the length of floss. Then, wrapping the length of floss around a user's finger and flossing.

An apparatus comprising a handle, a toothbrush head and a cover. The handle may comprise a flat surface, a cavity and a first connector. The toothbrush head may comprise a plurality of bristles at a first end and a second connector at a second end. The cover may be configured to expose the cavity when not placed over the cavity and conceal the cavity when the cover is fit over the cavity. The cavity may be configured to store a floss dispenser. The floss dispenser may comprise floss and a cutter. The cavity may enable the floss dispenser to be replaced. The floss dispenser may be exposed on said the surface when the door is opened. The first connector may be configured to be removably attached to the second connector to enable the toothbrush head to connect with the handle.

An apparatus for performing a localization of a movable treatment device having at least one inertial sensor and configured to treat the target surface. The apparatus has a motion pattern classification device configured to discriminate between two or more motion classes contained in a set of motion classes, and an interface for providing, from the inertial sensor to the motion pattern classification device, inertial sensor data representing a movement of the movable treatment device. The motion pattern classification device has a neural network configured to receive and classify inertial sensor data with respect to the motion classes associated with one or more different zones relating to the target surface so that the classification of inertial sensor data indicates an estimation of the location of the movable treatment device with respect to the one or more zones of the target surface.

A multipurpose device for personal hygiene includes a brush for cleaning and brushing teeth and extending to a housing defining and outer wall presenting a shoulder and a cavity defined in the housing presenting an inner wall. The multipurpose component is disposed inside the cavity and defines an axis extending through the multipurpose component and the housing. The multipurpose component presents an element allowing the human to floss between the teeth and further allowing the human to selectively splay fluid into mouth through an open end of the housing and cleaning bits of food out of the teeth by removing a toothpick from a cap.
