Abstract: A skincare device includes a brushhead; a body including a motor assembly configured to oscillate the brushhead and an inertial measuring unit (IMU) configured to determine kinematic measurements of the device; a first optical encoder including a light source and an optical sensor configured to capture images; and processing circuitry configured to determine a location of the brushhead with respect to a body part of the user based on a combination of data measured from the IMU and the first optical encoder.

Abstract: An instrumented comb, including bristles protruding from the handle, the bristles spaced apart from each other such that a first set of two or more bristles are spaced by a first distance, a second set of two or more bristles are spaced by a second distance, and a third set of two or more bristles are spaced by a third distance, wherein the third distance is greater than the second distance and the second distance is greater than the first distance. The comb includes a controller receiving signals from: a contact sensor to detect contact with a scalp, and a magnetic compass to determine location on the scalp. The comb uses the signals to record the detected contact information and determined location information as the comb undergoes a brushing gesture over a scalp, measure hair density based on the contact information and location information, and output the measured hair density.

Abstract: A system that includes a styling tool configured to treat or shape a user's hair; and a client device configured to communicate with the styling tool and provide feedback to the user regarding a user's usage of the styling tool based at least in part on measured data captured by the styling tool. The styling tool may be a hairbrush that includes circuitry and/or sensors configured to detect one or more of sound, acceleration, force, rotation, hair humidity, and ambient temperature and humidity.

Abstract: A method, system, and device for measuring and evaluating hair loss over time is disclosed. A instrumented comb device includes a power source, a controller, and associated sensors. The controller receives signals from the sensors, including a contact sensor to detect contact with a scalp and obtain a hair count, and a magnetic compass to determine location on the scalp. The controller includes one or more processors that acquire and record the detected contact information and determined location information as the comb device is stroked over a scalp, and measure hair density based on the contact information and location information. The instrumented comb can communicate with a remote information system or a mobile device for auxiliary processing and display. Machine learning of the remote information system allows for recognizing hair density or prediction of future trends in hair density over time using data recorded by the sensors.
