AMENDED CLAIMS

received by the International Bureau on 5 December 2013 (05.12.2013).

1. A hair straightener for performing a grooming task on a user, the straightener being able to perform the grooming task in at least a first mode or in a second mode, which is different to the first mode and comprising at least a first and a second sensor for measuring user data relevant to the grooming task, a user interface enabling the user to enter further user related data relevant to the grooming task and a data processing unit, characterized in that the data processing unit generates a selection signal for selecting at least either the first or the second mode depending on the data measured by the at least first and second sensors and depending on the user related data entered and in that the first and second sensors are provided to measure temperature and/or hair wetness and in that the data entered via the user interface relates to at least one of hair length, hair density and/or hair color and the sensors being provided to measure a different physical property than that of the data enetered via the user interface.

2. The hair straightener of claim 1 , characterized by a data storage unit and wherein the data processing unit generates a selection signal also depending on the data stored in the data storage unit.

3. The hair straightener of claim 2, wherein the data storage unit stores non-individual data.

4. The hair straightener of any one of claims 2 or 3, wherein the data storage unit stores individual data which are at least in part generated during usage by the user.

5. The hair straightener of any one of preceding claims, wherein the straightener is designed to perform the grooming task in a multitude of modes, the multitude comprising at least three modes and wherein the data processing unit is generating a selection signal for any one mode out of the multitude of modes.

6. The hair straightener of claim 5, wherein the multitude of modes comprises distinct modes or continuous modes.

7. The hair straightener of any one of the preceding claims, characterized by a heating or cooling device for performing the grooming task at a given temperature level and wherein 2

the modes are temperature levels.

8. The hair straightener of any one of the preceding claims, wherein the data measured by the first sensor form a first data set comprising a first number of data and wherein a second data set comprising a second number of data is generated using data from the first data set and the second number is smaller than the first number.

9. The hair straightener of any one of the preceding claims, wherein the data measured by the at least one sensor form a first data set comprising a data representing a first physical property, in particular temperature, and wherein a second data set comprising a data representing a second physical property, in particular hair wetness, is generated using data from the first data set and the second physical property is different from the first physical property.

10. The hair straightener of claim 8 or 9, the second data set is generated in a process using data provided by the data storage unit.

11. The hair straightener of any one of the preceding claims, wherein the interface comprises a display and an input device.

12. The hair straightener of any one of the preceding claims, wherein the first and second sensors are provided to measure temperature at two lateral locations of the hair straightening plate or adjacent to that which are remote to each other and arranged in a direction of the hair movement through the straightener, so that both sensors are contacted by the users hair during use of the straightener.

13. The hair straightener of any one of the preceding claims 2- 12, wherein a central

processor automatically selects based on the selection signal the appropriate mode by a comparison of the data entered via the user interface and sensor measurement data with pre stored data stored in the data storage unit.

14. The hair straightener of any one of the preceding claims 2- 13, wherein the data stored in the data storage unit is a knowledge data base that includes non individual usage data generated from a large variety of users representative for an unspecified variety of users 3

or representative for a certain subset of users.

15. A personal appliance for performing a grooming task on a user, the appliance being able to perform the grooming task in at least a first mode or in a second mode, which is different to the first mode, the personal appliance comprising at least one sensor for measuring user data relevant to the grooming task, the personal appliance being characterized in that

it further comprises a user interface enabling the user to enter further user related data relevant to the grooming task and the personal appliance comprising a data processing unit, the data processing unit generating a selection signal for at least either the first or the second mode depending on the data measured by the at least one sensor and depending on the user related data entered.

16. The personal appliance of claim 1, characterized by at least one of the features of claims
