Embodiment Construction

[0036] figure 1 is a block diagram of the hair cutting device 100 . figure 2 A hair cutting device 100 in the form of a hand shaver is shown according to an exemplary embodiment of the invention. The hair cutting device 100 is used to cut (eg, shave) hair on a subject's body. The subject can be a human or an animal. The hair may be facial hair (ie, hair on the subject's face) or hair on the subject's head or other parts of its body (legs, chest, etc.).

[0037] The hair cutting device 100 comprises a cutting element 102 which enables hair to be cut when the hair cutting device 100 is moved over the skin of a subject. The cutting element 102 is an optical waveguide 102 which is arranged on the hair cutting device 100 such that the optical axis of the optical waveguide 102 (i.e. the line along which light normally travels through the optical waveguide 102) is substantially perpendicular to the hair cutting device. 100 is moved such that as hair cutting device 100 is moved a...

Abstract

There is provided a method (500) of treating an optical waveguide. The method comprises applying (502) the volume of ferrofluid to the optical waveguide, and applying (504) a magnetic field to the volume of ferrofluid to move the volume of ferrofluid at least partially along a length of the optical waveguide. A personal care device and a system are also disclosed.

Description

technical field [0001] The present invention relates to an optical waveguide, and more particularly, to a method, device and system for processing optical waves. Background technique [0002] A shaving device using laser light has been proposed in WO 2014 / 143670. In particular, a laser source configured to generate laser light having a wavelength selected to target a predetermined chromophore to effectively cut a hair shaft is provided. The fiber optics are located on the shaving portion of the device, which is positioned to receive the laser light from a laser source at the proximal end, conduct the laser light from the proximal end toward the distal end, and emit light to the fiber optic's cutting section when the cutting area comes into contact with hair. out of the area and toward the hair. [0003] Over time, the use of such shaving devices can cause the fibers to become dirty. For example, debris such as hair clippings, dust or dirt may accumulate on the optical fib...
