An electric toothbrush includes a gyro sensor inside a main body. The gyro sensor detects an angular velocity of the main body and the main body includes a head portion, a neck portion, and a grip portion in a longitudinal axis direction. An angle formed by a longitudinal axis of the main body in a state that brush bristles of the head portion contact with a brushing site in a dentition with respect to the longitudinal axis of the main body in a state that the brush bristles of the head portion contact with a reference position in the dentition is obtained, based on an output from the gyro sensor. A corresponding point corresponding to the brushing site on an approximate curve that curves corresponding to the dentition is obtained based on the angle, and coordinates of the corresponding point are used as a translational position of the brushing site.

This disclosure presents systems and methods to improve user brushing behavior. Exemplary implementations may: effectuate presentation of audio content via an audio output device, the audio content being characterized by an audio profile; obtain output signals from one or more sensors coupled to a user device, the output signals conveying user input information, the user input information defining user input by a user via the user device; determine, based on the user input information, a user profile, the user profile including one or more user values of the one or more audio attribute; compare the user profile with the audio profile to determine, for individual audio attributes, one or more differences; determine one or more scores reflecting the one or more differences; and/or perform other operations.

A system and method for monitoring and analyzing activities of a user operating an electric tooth brush having an electric motor. The magnetic field induced by motions of the electric motor can be detected by a sensor array to generate signals. The signals are processed to determine a position of the brush head and a roll angle of the brush head. Based on the position and roll angle of the brush head, the surface of the teeth of the user, which is being brushed by the brush head, can be determined. This operation can be repeated to determine whether all the surfaces of the teeth have been brushed.

An oral cleaning and/or treatment device includes electrodes for emitting RF energy for providing an oral cleaning and/or treatment function. The device includes a cleaning unit for receipt in an oral cavity which includes at least a first and second protruding member, which protrude in a same general direction away from abase or support structure. Each member comprises one or more electrodes or conductive elements for emitting RF energy. The device generates an RF field in a space between and around the electrodes by driving the electrodes with an RF signal generator. The device includes means, either mechanical or electrical, for varying a generated RF field pattern (e.g. spatial intensity distribution) between different settings. The device is in particular configurable in at least two modes or settings, each associated with a different respective field pattern or spatial intensity distribution. This is valuable for adapting the cleaning functionality to different required purposes.

An oral care system including an oral care device and a processor. The oral care device includes a head having cleaning elements and a vibrational sensor configured to determine vibrational data emitted by the oral care device in use. The processor is operably coupled to the vibrational sensor and is configured to: determine, based on the vibrational data, an applied pressure of the cleaning elements upon an oral cavity of a user; determine an optimal pressure associated with the oral cavity of the user and a non-optimal pressure associated with the oral cavity of the user; and based on the applied pressure of the cleaning elements upon the oral cavity being substantially the non-optimal pressure, cause the applied pressure of the cleaning elements upon the oral cavity to be substantially the optimal pressure.

A tire shine application system includes a computer having at least one sensor interfaced thereto that detects and measures sizes of a tire of a vehicle as the vehicle enters a car wash. A tire shine applicator is interfaced to a three-directional movement device that is controlled by the computer. When the tire approaches the tire shine applicator, the computer controls the three-directional movement device to position the tire shine applicator to an outwardly facing wall of the tire and controls the three-directional movement device so that the tire shine applicator traverses the outwardly facing wall of the tire while tracking the tire as the tire shine applicator deposits tire shine liquid on the outwardly facing wall of the tire.

A method of providing tooth-brushing guide information according to an embodiment of the present invention includes an operation in which a user terminal analyzes a captured image of a user, recognizes the face of the user, and identifies landmarks of the face; an operation in which the user terminal generates a personalized dental model of the user using the landmarks, an operation in which the user terminal provides a virtual dental image by augmented reality using the dental model; and an operation in which the user terminal provides tooth-brushing guide information using the dental model.

There is provided an electric toothbrush including a toothbrush head, a toothbrush handle and a force sensing array. The force sensing array is arranged on the toothbrush head and/or the toothbrush handle. When the force sensing array is arranged on the toothbrush head, it is able to detect the force uniformity of brush hairs. When the force sensing array is arranged on the toothbrush handle, it is able to control the vibration strength of the brush hairs and detect the pressing force of the brush hairs.

A method for oral care. In one aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect motion of an oral care device during a brushing routine of a user, the sensor data corresponding to the detected motion; and b) determining a target brushing time based on the sensor data. In another aspect, the method for oral care includes a) receiving sensor data from at least one sensor configured to detect brushing intensity during a brushing routine of a user, the sensor data corresponding to the detected brushing intensity; and b) determining a target brushing time based on the sensor data.

There is provided a controller for a fluid-detection system, wherein the controller is configured to: determine if a user is interacting with the fluid detection system, wherein the determining comprises at least one of: determining whether a user is within a predetermined distance of the fluid detection system; determining whether a user is in physical contact with the fluid detection system; determining whether a fluid sensor of the fluid detection system is in a mouth of a user; and control the temperature of the fluid sensor of the fluid detection system based on the result of the determination. There is also provided a fluid based detection system comprising the controller, a device comprising the controller, a remote device comprising the controller, and a computer implemented method for controlling a fluid detection system, the method comprising the steps of: determining if a user is interacting with the fluid detection system, wherein the determining comprises at least one of: determining whether a user is within a predetermined distance of the system; determining whether a user is in physical contact with the fluid detection system; determining whether a fluid sensor of the fluid detection system is in a mouth of a user; and controlling the temperature of the fluid sensor of the fluid detection system based on the result of the determination.
