A cosmetic device with an exchangeable application head and a device body is disclosed, wherein the device body contains a motor and drive mechanism, an actuating switch, a power supply, a head recognition element and a control element adapted to control the motor and drive mechanism based on an actuation of the actuation switch and the application head recognized by the head recognition element. It is provided that the head recognition element comprises at least one mechanical switch disposed on a carrier fixed at the device body. Further, a flexible actuation area is disposed in front of the at least one mechanical switch. The exchangeable application head has at least one recognition generating protrusion actuating through the flexible actuation area on one of the at least one mechanical switches when the exchangeable application head is mounted at the device body.

A connected health care system is provided with various devices for tracking and monitoring health statistics and behaviors including oral health, fitness, heart health, bone health, salivary diagnostics, diabetes, and further options that will be explored in the subsequent sections. The connected health care system is comprised of various devices, a data transfer medium (i.e. “smartphone”), and the Cloud, which allows for data transfer between multiple platforms and devices. Some devices comprised in the connected health care system include a toothbrush, a connected surface with sensors, a salivary diagnostic system, a breath analysis system, and further devices that will be explored in the subsequent sections. The connected health care system further provides a user identification system utilizing capacitive coupling of the human body between devices.

A hair brush for use in a hairdressing store, a beauty shop, or at home, is able to easily and freely create a hair style by arranging flexible brush pins to a brush pedestal of the hairbrush so that the hair is easily entangled around the brush portion. The brush pedestal is further provided with a large number of hot air injection holes to inject hot air generated by a heater and a fan formed at an inside of the brush pedestal. Thus, hair styling using the hot air by one-handed operation is possible. Further, since the brush pedestal is heated by receiving the heat generated by the heater, the brush pedestal in contact with the hair becomes hot and thus an iron effect at the time of hair styling can be obtained.

A computer-implemented method including deriving a health profile of a user from a sample taken from the user and displaying a representation of the health profile on a display, wherein the representation of the health profile includes a list of undesirable oral health characteristics that are detectable from the sample. The representation of the health profile may also include a list of desirable oral health characteristics that are detectable from the sample. Furthermore, a user may select one of the undesirable health characteristics, and in response an indication of historical values associated within he selected one of the undesirable health characteristics may be displayed on the display.

A haircare apparatus has a plurality of capacitive sensors, each capacitive sensor configured to provide a capacitance reading indicative of hair proximal to the haircare apparatus. The haircare apparatus has a moisture estimation module configured to estimate, based on capacitance readings of the plurality of capacitive sensors, a moisture level of the hair proximal to the haircare apparatus.

A cosmetic device with an exchangeable application head and a device body, wherein the device body contains a motor and drive mechanism, an actuating switch, a power supply, a head recognition element and a control element adapted to control the motor and drive mechanism based on an actuation of the actuation switch and the application head recognized by the head recognition element. It is provided that the head recognition element comprises at least one mechanical switch disposed on a carrier fixed at the device body. Further, a flexible actuation area is disposed in front of the at least one mechanical switch. The exchangeable application head has at least one recognition generating protrusion actuating through the flexible actuation area on one of the at least one mechanical switches when the exchangeable application head is mounted at the device body.

A system is provided that includes a hair dryer and a hairbrush. The hairbrush is configured to sense a characteristic of at least one of the user's hair and the hair dryer, and to transmit information back to the hair dryer based on the sensed characteristic. The hair dryer is configured to update at least one setting, which may include least one of temperature control, air flow speed, and air flow shape at the hair dryer, based on the received sensed characteristic.

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 smart toothbrush is provided. The smart toothbrush includes a toothbrush head configured to be provided with bristles, a toothbrush body configured to be connected to the toothbrush head and to be able to be held, a temperature sensor configured to measure a temperature within an oral cavity of a user while the user is brushing teeth using the smart toothbrush, and a processor configured to determine a tooth brushing section in which the user is brushing teeth within the oral cavity, based on a temperature value measured by the temperature sensor.

A computer-implemented method including deriving a health profile of a user from a sample taken from the user and displaying a representation of the health profile on a display, wherein the representation of the health profile includes a list of undesirable oral health characteristics that are detectable from the sample. The representation of the health profile may also include a list of desirable oral health characteristics that are detectable from the sample. Furthermore, a user may select one of the undesirable health characteristics, and in response an indication of historical values associated within he selected one of the undesirable health characteristics may be displayed on the display.
