In one embodiment, an oral care system is disclosed that includes an oral care device and at least one programmable processor. The oral care device includes a head having a reference face, a light source, at least one orientation sensor generating orientation data corresponding to orientation measurements of the reference face during a freeform oral care routine, and at least one optical sensor generating optical sensor data representing optical feedback resulting from the light from the light source being incident upon sections of the oral cavity. The processor, based on the orientation data, determines which optical sensor data corresponds with which of the sections of the oral cavity. For each section of the oral cavity, based on the corresponding optical sensor data, the processor determines an oral care characteristic.

Devices, systems, and methods for real-time peeling are disclosed. Peeling can include including evaluating and controlling one or more peelers to remove peel from organic materials. Evaluation can be performed by an evaluation system including a convolutional neural network to determine a peel value. Control can be performed by a machine learning model on the basis of the peel value. Control can include determination of real-time settings for peeler tool speed and/or gate position.

An oral care device having a head with cleaning elements and a handle coupled to the head. The handle may include a selectively rotatable ring arranged between the head and a distal end of the handle that is configured to allow a user to select a desired mode of operation of the oral care device. The handle may include a selectively illuminated light that is configured to display at least one color that visually indicates that certain behaviors, patterns, and/or consistent habits have been performed successfully. The handle may include a processor configured to track a duration of a user's brushing session, a light ring on a bottom surface of the handle, and a pressure sensor. Respective portions of the light ring may be selectively illuminated by the processor to visualize progress toward achieving a predetermined brushing routine time and/or to visualize an over-pressure condition sensed by the pressure sensor.

An electric toothbrush and a control method thereof includes a brush head, a brush handle, a motor, a pressure responding unit, and a control unit. The motor is disposed in the brush handle, a driving shaft of the motor penetrates through the brush handle and is connected with the brush head for driving. The pressure responding unit is disposed in the brush handle, and the pressure responding unit is configured to acquire a force of the brush head. The control unit is disposed in the brush handle, and the control unit is electrically connected with the pressure responding unit and the motor.

A universal base for an electric toothbrush has a body comprising a top surface, a bottom surface, and a side surface therebetween. The base can be coupled with the toothbrush for wireless communication therebetween. The base includes a charging component for inductively charging the electric toothbrush, a Bluetooth component for communicating usage data received from the toothbrush during a brushing session, an analyzing component for instantaneous processing of the usage data received from the toothbrush, a timer-clock component for displaying either a count-up or a countdown of the brushing session during the brushing session and time of day before and after the brushing session, and a multi-functional light component for instantaneously communicating, during the brushing session, at least one element of the usage data.

A system for detecting blood in an oral cavity during toothbrushing. The system may include a toothbrush having a sensor that is configured to emit first light at a first wavelength and second light at a second wavelength, receive reflected portions of the first and second light, and generate a first signal indicative of a first intensity of the reflected portion of the first light and a second signal indicative of a second intensity of the reflected portion of the second light. The system may include a processor operably coupled to the sensor, the processor being configured to receive the first and second signals and calculate a ratio of the first intensity to the second intensity to determine whether hemoglobin/blood is present in the oral cavity. The processor may be a part of the toothbrush or a part of a portable electronic device such as a smart phone.

A pet care device may include a head having a sterilizer and a handle extending from the head. The head may be formed of an outer body and an inner body positioned in an inner region of the outer body. A first space may be formed between the outer body and the inner body in which the sterilizer is provided. The sterilizer may include at least one light emitting device, and a light device may cover the first space. A second space partitioned from the first space may be at least partially located inside the inner body. Hair and/or debris may be collected in the second space.

An apparatus is provided that stabilizes an applicator in response to the motion caused by a user, comprising: a receiver configured to be coupled with a cosmetic applicator; at least one sensor configured to detect a movement caused by a user; circuitry configured to determine a compensation movement to offset the detected movement; and at least one motion generation device embedded in the receiver configured to control a motion of the cosmetic applicator according to the determined compensation movement.
