Abstract
A hair trimming device arranged to detect positions of the hair trimming device in relation to a client's head and to adjust its trimming length automatically and dynamically according to preprogrammed values at any given point during a hair trimming session.
Claims20
A hair trimming device comprising:
- a hair cutting mechanism comprising a movable blade and a static blade, wherein the movable blade is movable with reference to the static blade to cut hair there between;
- a tracking system comprising a transmitting device and a sensing device, wherein the sensing device is configured to detect a position of the transmitting device and thereby detect a position of the hair trimming device in relation to a head of a person on whom a hair trimming is being performed;
- a length adjusting mechanism coupled to the hair cutting mechanism, the length adjusting mechanism including a motor configured to move the hair cutting mechanism relative to the head of the person on whom the hair trimming is being performed to set a hair trimming length of the hair cutting mechanism;
- and
- a processor coupled to the tracking system and the length adjusting mechanism, wherein the processor is configured to calculate the hair trimming length set by the length adjusting mechanism automatically for all hair lengths that correspond to hair trimming positions on the head other than various individual position points based on previously generated hair length profile data that identifies a corresponding hair length only at the various individual position points on the head, and while the hair trimming device is guided by a user on the head of the person, the processor is further configured to dynamically adjust the hair trimming length set by the length adjusting mechanism automatically according to a detected present position of the hair trimming device, wherein the dynamic adjustment comprises dynamically adjusting the hair trimming length set by the length adjusting mechanism to the corresponding calculated hair trimming length automatically for all hair lengths that correspond to hair trimming positions on the head other than the various individual position points and dynamically adjusting the hair trimming length set by the length adjusting mechanism automatically to the corresponding hair length when the detected present position is at the various individual position points.

A method of controlling a hair trimming device including a hair cutting mechanism to trim hair, the method comprising acts of:
- calculating hair lengths for all positions that correspond to hair trimming positions on the head that do not correspond to various individual position points on the head based on previously generated hair length profile data that identifies a corresponding hair length only at the various individual position points
- guiding the hair trimming device on a head of a person on whom a hair trimming is being performed;
- detecting positions on the head, wherein the detected positions correspond to individual position points on the head or do not correspond to the individual position points on the head;
- and
- while the hair cutting mechanism is guided on the head, dynamically adjusting a hair trimming length of the hair cutting mechanism automatically according to the detected positions and the calculated hair lengths for all the detected positions that correspond to hair trimming positions on the head other than the various individual position points, and
- while the hair cutting mechanism is guided on the head, dynamically adjusting the hair trimming length set by the length adjusting mechanism automatically to the corresponding hair length when any of the detected positions are one of the various individual position points.
