A shaving aid for razor cartridges comprising water soluble filaments exhibiting lubricating properties and with improved visual and tactile aesthetics.

Systems, devices, and methods for applying machine learning to provide feedback related to a personal care device are described. Embodiments of the systems, devices, and methods may identify data from a device such as a razor comprising a plurality of sensors on a razor, predict one or more features such as shaving features based on the data using a machine learning model trained using data from the plurality of sensors, and provide shaving feedback based on the one or more features such as shaving features. Embodiments of the systems, devices, and methods may train a machine learning model, execute a trained machine learning model, capture and/or process data for the machine learning model, provide feedback based on the output of the trained machine learning model, or combinations thereof.

A shaving system including a shaver having a handle, a razor cartridge, and one or more sensors, wherein the one or more sensors may be configured to detect a characteristic of at least one of the shaver or a body part of a user and to generate a sensor signal representative of the characteristic. A processor may be operably coupled to the one or more sensors and may have at least one algorithm stored thereon for analyzing the sensor signal to determine a status of the shaving session. An indicator may be operably coupled to the processor, and the indicator may be configured to provide feedback to the user regarding the status of the shaving session.

A shaving system, comprising a shaver including a handle a cartridge having at least one blade, the cartridge pivotably connected to the handle about a transverse axis of the handle; and a biasing element connected to the handle and connected to the cartridge, the biasing element being configured to move along a longitudinal axis of the handle in response to the cartridge pivoting about; a sensor configured to determine a pivot angle of the shaver cartridge relative to the handle; and a processor configured to receive information about the movement of the biasing element and determine an angle between the cartridge and the handle about the transverse axis based on the information.

A method of resetting a digital counter for a personal care appliance by sending an electrical output signal from an optical sensor to a control circuit. The electrical output signal is compared to a predetermined value with the control circuit or a change in the electrical output signal from the optical sensor is detected over time. A signal is sent to a consumer user interface by the control circuit based on the electrical output signal and the predetermined value or based on the change in the electrical output signal from the optical sensor. The digital counter is reset based on an input signal from the consumer user interface.

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 consumer appliance with a body. A cartridge removably mounted to the body. The cartridge having a surface with a first colored region and a second colored region. A control circuit positioned within the body. A first emitter that projects a first light at the first colored region and a second light at the second colored region. A first light sensor mounted the body that sends a first signal to the control circuit based on a color of light reflected from the first colored region. A second light sensor mounted to the body that sends a second signal to the control circuit based on a color of the light reflected from the second colored region.
