US Patent 10918185 Hair styling device

A hair styling device for a hairstylist includes a housing configured to be attachable to a styling tool such as a comb, an electronic-based alignment means that determines the angle of orientation of the housing, and a user-actuated operational control for selecting the housing's desired angle of orientation. The electronic-based alignment means provides a human-perceivable indication of the angle of orientation and can be selectively locked to a desired angle. The electronic-based alignment means also selectively provides a human-perceivable indication when the housing is approaching and has arrived at the desired angle.
