A system and method for operating a personal grooming/household appliance, including: providing a personal grooming/household appliance including at least one physical sensor taken from a group consisting of: an orientation sensor, an acceleration sensor, an inertial sensor, a global positioning sensor, a pressure sensor, and a load sensor, audio sensor, humidity sensor, and a temperature sensor; providing a camera associated with the personal grooming/household appliance; classifying data received from the physical sensor and from the camera using at least one trained machine learning classifier to generate an augmented classification; and providing user feedback information based upon the augmented classification or modifying operation of the grooming/household appliance based upon the augmented classification.

An oral care system including a toothbrush having a sensor that generates brushing data during a brushing session and a programmable processor. The programmable processor may be configured to receive the brushing data from the sensor, receive oral characteristic data indicative of an oral characteristic of the user, and determine at least one of a suggested brushing routine and a brushing evaluation for a brushing session based at least in part on the oral characteristic data and the brushing data. The oral characteristic may be present in or adjacent to a first portion of the dentiture. The brushing evaluation or brushing routine may be based on or includes at least one of: an altered target brushing time for the first portion of the dentiture; and a modified brushing motion expectation for the first portion of the dentiture.

A system and method for operating a personal grooming/household appliance, including: providing a personal grooming/household appliance including at least one physical sensor taken from a group consisting of: an orientation sensor, an acceleration sensor, an inertial sensor, a global positioning sensor, a pressure sensor, and a load sensor, audio sensor, humidity sensor, and a temperature sensor; providing a camera associated with the personal grooming/household appliance; classifying data received from the physical sensor and from the camera using at least one trained machine learning classifier to generate an augmented classification; and providing user feedback information based upon the augmented classification or modifying operation of the grooming/household appliance based upon the augmented classification.

A brushing tracker configured to be mounted to a toothbrush has a motion sensor and a transceiver that collect and output raw motion data. The raw motion data is received by a relay and forwarded to a cloud-based remote processing system that processes the raw motion data to determine brushing adequacy based on predetermined criteria. The motion sensor and transceiver are disposed in a flexible case. An attachment band enables the brushing tracker to be affixed to a standard toothbrush for use and affixed to a different toothbrush when desired.

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.

Disclosed is an oral cleaning kit, including an interdental brush, an oral viewer, a container, and a holder. The container includes an upper cover and a base. Oral cleaning appliances such as the interdental brush, the oral viewer, toothpaste and a toothbrush may be disposed in the container. The base includes a fixed clamping ring and a storage tank. The upper cover may be used as a tooth mug and is detachably mounted on the base. The holder may be provided on the container. When the holder is unfolded, a mobile phone may be disposed on the holder, and the cleaning process may be observed through the mobile phone in real time. The oral cleaning kit has the advantages of carrying convenience, simple use and hygiene.

Oral hygiene monitoring system is disclosed to track motion and orientation of an oral hygiene device. The control system may process data output from a motion sensor to determine position and orientation of an oral hygiene device with respect to a user's mouth. In some examples, the system may use machine learning techniques to identify position and orientation, brush stroke type, and other specific actions.

An oral care implement has a front side and a back side opposite the front side and an overall length extension between mutually opposite proximal and distal ends. A head of the implement, disposed at the proximal end, has at least one cleaning element extending from the front side. A handle is at least partially made from a material having a density higher than that of the head's material. The handle's cross-sectional area, extending substantially perpendicular to the overall length extension, has a height extension between the front and back sides. The implement has a center of gravity situated below an axis of rotation when the oral care implement is placed with its back side on a surface. The center of gravity is closer to the back side than to the front side of the implement when measured along the height extension of the handle.

An oral care implement has an overall length extension extending between a proximal end and a distal end, the distal end being opposite the proximal end. The oral care implement comprises a head at the proximal end and a handle, the handle being at least partially made from a material having a density being higher than the density of the material of the head. The oral care implement has a center of gravity located at a distance measured from the distal end, and the ratio of said distance to the overall length extension of the oral care implement is from about 0.30 to about 0.45, preferably from about 0.35 to about 0.42, further preferably from about 0.38 to about 0.41.
