• the personal appliance can be can be a grooming appliance, for example a shaver, a trimmer, a beard trimmer, an epilator, or a hair care device, e.g. a curler, a straightener, a brushe, a hair dryer, and the like.
• a grooming appliance for example a shaver, a trimmer, a beard trimmer, an epilator, or a hair care device, e.g. a curler, a straightener, a brushe, a hair dryer, and the like.

• the personal appliance can also be an epilator.
• a first mode could be one of slow motion of the epilation roll and a second mode could be one of a fast movement of the epilation roll.
• the grooming task will typically be the task of drying hair or straightening hair or curling hair.
• the temperature at which the task is performed is critical.
• a first mode for such hair care grooming task could be a mode of low temperature and a second mode for a hair care grooming task could be a mode of high temperature.
• the personal appliance will comprise at least one sensor for measuring user data relevant to the grooming task.
• these data depend on the nature of the task. For example the skin temperature or skin dryness could be measured.
• the hair temperature or hair dryness or hair wetness could be measured.
• user data will be representative for an aspect or a feature of the user's body and the state this body or part of the body is in.
• the personal appliance should further comprise a user interface enabling the use to enter user related data.
• user related data can for example be skin type, skin color and tone, skin dryness, frequence of doing the same or a different grooming task, hair color, hair length, density of body hair, or the like. The interface will allow the user to enter such data.

These devices can be connected to the personal applicance via a cable or via a wireless connection, using e.g. the W-LAN or Bluetooth connection elements and protocols.
• the data storage unit may alternatively or in addition also store individual data which are at least in part generated during usage by the user.
• the applicance is then able to improve its performance (select the most appropriate mode or temperature setting of the heating plates of a straightener) in shorter time due to the training occurred by earlier usage.
• the appliance is then "self-learning". This aspect can be also indepenedently claimed in the context of the other features described hereinbelow and above.
• the personal appliance will further comprise a data processing unit. This processing unit is able to perform mathematical and logical operations.
• the unit will typically comprise integrated circuits and similar parts often used in computers.
• the data processing unit will generate a selection signal for either the first or the second mode. This signal can then be used to trigger the selection of the respective mode.
• the signal will be low volt signal and suitable electrical or electronic means will be required to transform the signal into a signal suitable to actually trigger the selection. It is useful in the context of the present invention, that the selection signal generated by the data processing unit is performed into a second selection signal. Such a second selection signal can be more suitable to trigger the desired selection, for example be of higher voltage.
• the selection signal is generated in a complex operation and depends at least on the data measured by the at least one sensor and also on the user related data entered.
• the combination of such various data provides a higher quality of the selection signal. That means, that the signal is more likely to trigger the selection of an ideal grooming mode as compared to signals generated in a simpler way, for example by a user selection only or by a sensor selection only.
• a first mode and a second mode a third mode, a fourth mode, and so forth can exist.
• the different mode can be different temperature settings.
• the second mode comprises features of the first mode and additional features.

• a personal appliance which further comprises a data storage unit.
• a data storage unit can take a variety of commonly known forms.
• the data processing unit can then generate a selection signal also depending on the data stored in the data storage unit.
• the nature of the data stored in the data storage unit can be quite different.
• the data can be non-individual.
• Such non-individual data are to be understood as data not generated relative to a specific individual user.
• data can be usage data generated from a large variety of users representative for an unspecified variety of users or representative for a certain subset of users (e.g. young women or the like).
• the two sensors can measure the same property, for example temperature. Two sensors can achieve a more accurate temperature measurement as compared to a single sensor.
• temperature data received from two sensors can be processed for achieving a different quality of information rather than temperature.
• the temperature difference between the front end and the rear end of the heating plates of a hair straightener can be representative for the dryness of the hair. If the hair is wet, it will normally absorb more heat from the heated plates of a hair straightener, and hence the temperature drop between the front sensor and the rear sensor (in a given stroke direction) is more pronounced. Therefore, a set of temperature data can be transferred into a set of dryness data. Dryness data are referred to as a data set of a different nature as compared to the temperature data set.
• a personal applicance is considered useful, wherein the data measured by the at least one sensor form a first data set comprising a data representing a first physical property and wherein a second data set comprising a data representing a second physical property is generated using data from the first data set and the second physical property is different from the first physical property.
• the first set of data can be temperature data and the second set of data can be dryness data.
• this conversion can be achieved by relying on data stored in the data storage.
• the data storage may have representative data for temperature drop depending on hair dryness.
• wetness data is the same physical property as dryness data for all embodiments.
• the personal appliance comprises a third sensor which measures data of a different nature than the first and the second sensor.
• the third sensor may measure hair dryness directly.
• the data of the third sensor can then be compared with the process data of the first two sensors. The comparison can then lead to an estimate about the reliability of the sensors and to an overall more accurate measurement.
• the data of the third different sensor can be used to create a data set of yet different quality. For example, when the dryness of the hair is known from data generated by the third sensor, the temperature data generated by the first and second sensor could be used to have an estimate for the speed with which the device is moved through the hair.
• the third sensor or a fourth sensor could also be a sensor measuring the position of the hair straightener.
