Abstract

In various embodiments, a hair treatment device is provided. The hair treatment device has a device body, a first sensor and a second sensor arranged in or on the device body, the first sensor adapted for detecting a hair condition parameter and the second sensor adapted for detecting movements and location changes of the device body. An electronic circuit device is arranged in or on the device body. The electronic circuit device is coupled to the first sensor and the second sensor, and further is configured to control a hair treatment parameter based on the received detected hair condition parameter and/or to dose a hair treatment agent and/or to provide a hair treatment recommendation. The electronic circuit device further is configured to determine a spatial position of the device body and/or a speed of the device body based on the received movements and location changes.

First claim

The invention claimed is:

1. A hair treatment device comprising:
a device body;
a first sensor arranged in or on the device body, the first sensor configured to detect a hair condition parameter;
a second sensor arranged in or on the device body, the second sensor configured to detect movements and location changes of the device body; and
an electronic circuit device arranged in or on the device body,
wherein the electronic circuit device is coupled to receive the detected hair condition parameter from the first sensor and the detected movements and location changes from the second sensor,
wherein the electronic circuit device is configured to control a hair treatment parameter and to dose a hair treatment agent based on the received detected hair condition parameter, and
wherein the electronic circuit device is further configured to (i) determine a spatial position of the device body and a speed of the device body based on the received movements and location changes of the device body, (ii) determine, based on the determined spatial position of the device body, which hair regions have already been treated with the hair treatment device, and (iii) transmit data indicative of the hair regions that have already been treated; and

a display device in operable communication with the electronic circuit, the display device configured to receive the data transmitted by the electronic circuit and, in response to receiving the data, to display at least the hair regions that have already been treated.

2. The hair treatment device according to claim 1 ,
wherein the hair treatment device comprises a straightening iron.

3. The hair treatment device according to claim 1 ,
wherein the electronic circuit device is further configured to determine whether the determined speed of the device body meets a predetermined criterion according to a provided speed for applying the hair treatment device.

4. The hair treatment device according to claim 3 ,
wherein the electronic circuit device is further configured to deliver a signal depending on whether the determined speed meets the predetermined criterion.

5. The hair treatment device according to claim 4 ,
wherein the signal comprises an acoustic signal, an optical signal and/or a haptic signal.

6. The hair treatment device according to claim 4 ,
wherein the delivery of the signal occurs during application of the hair treatment device.

7. The hair treatment device according to claim 1 ,
wherein the first sensor and the second sensor are sealed in the device body.

8. The hair treatment device according to claim 1 ,
wherein the electronic circuit device comprises a wireless data exchange device.

9. The hair treatment device according to claim 1 ,
wherein the second sensor is selected from the group of magnetic field sensors, gyroscopes, acceleration sensors, and mechanical displacement sensors.

10. A hair treatment system comprising:
a hair treatment device comprising:
a device body;
a first sensor arranged in or on the device body, the first sensor configured to detect a hair condition parameter;
a second sensor arranged in or on the device body, the second sensor configured to detect movements and location changes of the device body; and
an electronic circuit device arranged in or on the device body, wherein the electronic circuit device is coupled to receive and transmit the detected hair condition parameter from the first sensor and the detected movements and location changes from the second sensor, and

an external data processing device coupled to receive the detected hair condition parameter and the detected movements and location changes transmitted from the electronic circuit, the external data processing device configured, based on the detected hair condition parameter, to determine the control or regulation of a detected hair treatment parameter, determine a dosing for a hair treatment agent, and determine a speed at which hair treatment is to be performed, the external data processing device further configured to transmit the determined control or regulation, the determined dosing, and the determined speed to the electronic circuit device,
wherein the electronic circuit device is configured to control a hair treatment parameter and to dose a hair treatment agent based on the determined control or regulation, the determined dosing, and the determined speed transmitted thereto from the external data processing device.

11. The hair treatment system according to claim 10 , further comprising an actuator that is in electrical communication with the electronic circuit device and is configured to set a temperature of the device body based upon a hair condition parameter received from the electronic circuit device.

12. The hair treatment system according to claim 10 , further comprising an actuator that is in electrical communication with the electronic circuit device and comprises a dispensing device that is configured to dose a hair treatment agent based upon the determined dosing.

13. The hair treatment system according to claim 10 , further comprising a display device in electrical communication with the electronic circuit device.

14. The hair treatment system according to claim 10 , wherein the hair treatment device further comprises a heating device that is interposed between the first sensor and the second sensor in or on the device body.

15. The hair treatment system according to claim 10 , wherein the external data processing device is part of a smartphone, electronic or mobile tablet, personal computer, or a cloud-based server.

16. The hair treatment system according to claim 10 , wherein the external data processing device comprises a database of product recommendations based on hair condition.

17. The hair treatment system according to claim 10 , wherein the first sensor is selected from the group of a near-infrared spectroscope, a hair length sensor, an ultrasonic sensor, a photosensor, a thermal sensor, a spectrometer, and a camera.

18. The hair treatment system according to claim 10 , wherein the device body comprises a heating device and wherein the external data processing device is further configured to determine the control or regulation of a temperature of the heating device based on the detected hair condition parameter and transmit the determined control or regulation of the temperature of the heating device to the electronic circuit device.

19. The hair treatment device according to claim 1 , wherein the electronic circuit device is further configured to provide a hair treatment recommendation.
