A razor component comprises a cooling element, which is adapted to provide a cooling effect on a user's skin during a shaving operation, wherein the razor component includes a pressure-responsive phase-change component that is coupled to the cooling element.

A personal consumer product having an energy emitting element in selective electrical communication with a power source is provided. Thermal control circuitry is used to isolate the energy emitting element from the power source when a temperature of the energy emitting element exceeds a threshold. The thermal control circuitry includes a primary thermal control circuit and a redundant thermal control circuit. Methods for controlling the temperature of an energy emitting element of a personal consumer product are also provided.

A computer-implemented method (100) is described. The method includes obtaining (102) an indication comprising a skin parameter of a user. The obtained indication further includes an interaction between the user's skin and a hair removal unit. The method further includes determining (104) a position of the hair removal unit relative to the user's skin. The method further includes determining (106) a hair removal instruction for the user based on the indication and the position such that a user interface is caused (108) to provide the hair removal instruction for the user.

The present invention relates to a personal care device, in particular a hair removal device such as an electric shaver, comprising a working head for effecting a personal care treatment to a body surface, a handle for manually moving the working head along the body surface, and an adjustment device for adjusting a mechanical setting and/or a mechanical function of the working head and/or a part thereof, wherein a hazard determination device is provided for determining hazards for the personal care device, wherein the adjustment device is configured to adjust the working head and/or a part thereof into a safe harbor mechanical setting and/or a safe harbor mechanical function in response to a hazard signal from the hazard determination device.

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.

The present disclosure provides a razor accessory with a camera to assist the user of a shaving razor, which razor accessory is configured to be mechanically attached to the shaving razor. The razor accessory may be provided with sensors to track the shaving movements of a user. The present disclosure also provides an application for a wearable computer device to track the shaving movements of a user. The razor accessory and/or the wearable computer is communicatively connected to a vendor platform via an Internet-of-Things (IoT) gateway, which may provide feedback to assist and optimize the user's shaving experience.

A control device for a noncontact power supply device includes a power transmission coil for outputting an alternating magnetic flux upon receiving alternating electric power, and a power transmission control unit for controlling alternating electric power to be supplied to the power transmission coil. The power transmission control unit includes a first mode and a second mode. The first mode controls the alternating electric power to be supplied to the power transmission coil in order to transmit electric power, to be supplied to a load of a power reception device, to a power reception coil, and the second mode controls the alternating electric power for supplying electric power less than the electric power transmitted by the first mode to the power transmission coil. After being activated, the power transmission control unit selects initially the first mode.

A system and a method for adaptively releasing a lubricant or a cosmetic for a razor cartridge, a sensing unit detects a property of at least one of skin, air, water and a chemical agent in a region adjacent to the razor cartridge. A smart polymer provided on the razor cartridge is selectively responsive to a characteristic external stimulus by undergoing a physical or chemical change. A processing unit controls the release of the lubricant or the cosmetic by providing the characteristic external stimulus to cause the smart polymer to undergo a change. The processing unit compares the detected property to a reference threshold parameter and determines whether to provide the characteristic external stimulus to the smart polymer based on the comparison, thereby generating the lubricant or the cosmetic. The determined level of depletion of the smart polymer is indicated by a light, aural, or haptic indication.

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.
