A method (500) for calibrating a pressure sensor (28) of an oral cleaning device (10). The method comprises the steps of: providing an oral cleaning device comprising a body portion (12), an elongated member (14, 720) extending from the body portion and comprising a head (16, 770), a pressure sensor (28) configured to obtain a measurement of a force applied to the head by the user during a cleaning session, and a processor (32) configured to receive, from the pressure sensor, the measurement of force applied to the head; obtaining a non-zero load calibration parameter; and calibrating, by the processor using the non-zero load calibration parameter, the measurement of force received from the pressure sensor.

A method (800) for adjusting a user's oral care routine by an oral care device (10) based on interproximal spacing, the method including the steps of: (i) obtaining (820), using the oral care device, information about an interproximal space (66) in the user's mouth; and (ii) automatically adjusting (850), based on the obtained information, a parameter of the oral care device, wherein the dynamic adjustment is configured to improve oral care of the interproximal space.

A pressure washing system is disclosed for integration into a recreational vehicle or other large mobile vehicle. The wand of the system includes a rotating brush and one or more sensors to determine a distance from, pressure against, or orientation with respect to the vehicle. While a pump is supplying water to be output by the wand, the distance, pressure, orientation, or other sensor readings are continuously used to modify output characteristics of the wand, including the output water pressure and the speed of rotation of the brush. As a result, no more pressure is supplied by water or brush bristles than is necessary, avoiding overuse of water or damage to outer surfaces of the vehicle. Sensor readings may include one or more of a camera feed, sonar, lidar, pressure feedback, and accelerometer data. The system may also be responsive to a mobile app on a user's mobile computing device.

The invention is directed to a hair dryer with built-in laser diodes. The hair dryer provides one or more rows of laser diodes between rows of brush bristles to stimulate hair growth. The hair dryer provides an electric motor which operates quietly, and is battery operated with USB port and ionic technologies designed for the individual user's portability. A charging cradle with power cord is provided. The hair dryer also includes an air ionizer and a large assortment of attachments for additional grooming. Electric toothbrush and hair trimmer attachments may also be provided.

A computer-implemented method of training a user to effectively apply makeup using a computerized makeup brush, the method comprising the steps of receiving, from a computerized makeup brush that comprises one or more sensors for sensing the movement of the makeup brush relative to a particular portion of a user's body, data representing a movement of the makeup brush relative to the particular portion of the user's body over a particular period of time as the makeup brush is used to apply makeup brush to the particular portion of the user's body, and using the data to generate and display, to a user, a visual representation of the movement of the makeup brush over the particular period of time on a display that is operatively coupled to the computerized makeup brush.

A rotatable brush with a pressure sensor. The pressure sensor comprises a projecting blade connected to a tactile sensor by a flexible member. The projecting blade extends along the length of the shaft and is housed among the plurality of bristles protruding radially from the shaft. The projecting blade compresses the flexible member when pressure around the brush reaches a predetermined threshold. Upon compression of the flexible member, the tactile sensor, electronically coupled with a processor or controller, is activated thereby triggering a variety of possible preprogrammed responses.

A system is providing that includes processing circuitry configured to receive information of a specific sensed condition of a body part of a user detected by the at least one sensor of a device during a session, receive information of a tracked location of the device from a location tracker during the session, associate a specific time when the specific sensed condition is detected with a location of the device in space at the specific time, and determine a location on the body part in a three-dimensional virtual environment where the specific sensed condition occurs based on the associated specific time and location of the device.

An oral care device comprises a head portion and a handle portion. The head portion comprises at least one supporting arm and a base. The supporting arm extends from the base. A sensor is exposed from the supporting arm. The handle portion is configured to move relative to the head portion. The handle portion comprises a processor, wherein the processor is configured to receive signals from the sensor and analyze the signals received from the sensor.

A system is provided that includes a device configured to treat a body part of a user, the device including, at least one sensor configured to sense a condition of the body part; and a location tracker configured to track a location of the device in space, wherein the system is includes processing circuitry configured to receive information of a specific sensed condition of the body part detected by the at least one sensor during a session, receive, from the location tracker, information of the tracked location of the device during the session, and associate a specific time when the specific sensed condition is detected by the device with a location of the device in space at the specific time.

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.
