Disclosed is a vibration stimulation device. The vibration stimulation device includes a box having a cavity, vibrators disposed in the cavity; light emitting elements disposed between the vibrators or disposed on the vibrators, an upper vibration layer configured to connect the vibrators and the light emitting elements to edges of the box on the cavity, and bumps disposed on the vibrators.

A photo-bio-stimulation device uses near infrared (NIR) laser illumination of the scalp to promote hair growth with a lightweight user wearable device. All the remaining components are mounted on the concave underside of an outer cap shell. Many VCSEL laser device chips are surface mount soldered underneath of a single large flexible printed circuit. These discrete devices direct a diffused, near uniform flood of 678-nanometer monochromatic laser light deep into the hair roots and follicles across the scalps of its users. Petal shapes along a central spine are cut deep into the side edges of the flexible printed circuit to allow it to be conformed and fixed into a hemispherical dome and attached with dozens of plastic snaps inside the outer shell. This connects inside to a rechargeable battery and power controller. A protective clear covering matching the concave underside is attached along the brims.

According to an aspect, there is provided a treatment device for performing a treatment operation on or to a subject. The treatment device comprises: an optical diffuser arranged on the treatment device such that an outer surface of the optical diffuser is proximate to, or in contact with, skin of the subject when the treatment device is to be used to perform the treatment operation; and an imaging unit for obtaining one or more images using light passing through the optical diffuser into the treatment device; wherein the treatment device is further configured for providing one or more images to a processing unit for determination of whether the treatment device is in contact with the skin.

According to an aspect, there is provided an apparatus for use with a treatment device for providing feedback to a user on a treatment operation performed on a body part of a subject, wherein the treatment device is configured to apply light pulses to skin of the body part to perform the treatment operation, wherein a light pulse applied to the skin treats an area of the skin. The apparatus comprises a processing unit configured to receive a first measurement signal from a first sensor, the first measurement signal comprising information about positions and/or movements of the treatment device over time; for a light pulse previously applied by the treatment device to the body part during the treatment operation, process the first measurement signal to estimate a previous treatment position as a position of the treatment device relative to the body part when the light pulse was generated; for the previously applied light pulse and based on the estimated previous treatment position, estimate a previous treatment area for the light pulse corresponding to the area of skin of the body part that the light pulse was applied to when the treatment device was at the previous treatment position; process the first measurement signal to estimate a current position of the treatment device relative to the body part; based on the estimated current position of the treatment device, estimate a current treatment area corresponding to an area of skin that the treatment device would apply a light pulse to while in the current position; and generate a feedback control signal for a feedback unit, wherein the feedback control signal is configured to cause the feedback unit to generate feedback indicating whether the current treatment area corresponds, or substantially corresponds, to a previous treatment area.

A material for controlling light incident beneficial for treating skin conditions, wherein the material is arranged in a grid structure, wherein the grid structure is configured to have at least one grid portion, which includes one or more layers, wherein the at least one grid portion is configured in the article or apparatus to target an area of skin for treatment, the one or more layers of the at least one grid portion include at least one filter layer, configured to block light incident within a target wavelength range, based on filter layer material, which blocks light within the target range associated with a skin treatment, of each respective layer of the portion of the grid structure, wherein the filter layer is attached to the grid structure at the portion and configured to pass the at least one wavelength to treat an area of skin; and a protective layer, different from the at least one filtering grid portion of the grid structure, for reducing skin exposure to at least one of harmful light and non-beneficial light, by blocking at least one of harmful and non-beneficial wavelengths of the light passing through the filter layer material.

A hair-removal apparatus is provided, which includes a main body, a housing, a first air-inlet channel and a second air-inlet channel. The main body is accommodated in the housing and includes a heat-generating assembly and a refrigerating assembly. The first air-inlet channel communicates the refrigerating assembly with ambiance to absorb external air and dissipate heat from the refrigerating assembly, and the second air-inlet channel communicates the heat-generating assembly with ambiance to absorb external air and dissipate heat from the heat-generating assembly. The hair-removal apparatus is provided with two independent air inlet channels, which effectively enhances the heat dissipation performance of the hair-removal apparatus and improves the durability and safety of the hair-removal apparatus.

A light based therapy helmet has a circuit board layer which is equipped with multiple lighting dots. Each of the multiple lighting dots respectively is a first, a second or a third light-emitting unit. The first, the second and the third light-emitting units respectively emit a light of a first, a second and a third light band which respectively include a wavelength of 660 nm, 940 nm and 1600 nm. A lower helmet body is provided with an accommodation space configured for a user's head to be accommodated directly. An upper helmet body is provided with an accommodation space that fits the circuit board layer. When the lower helmet body, the circuit board layer, and the upper helmet body fit together, the circuit board layer is fixed between the upper helmet body and the lower helmet body. A controller controls the on/off and the brightness of the multiple lighting dots.

A personal therapy compartment includes a base of size to receive a human patient. The compartment includes a bed in the base said bed being made of a light transmissive material. An array of lights mounted is below the bed to transmit light onto a body supported on the bed. A control panel controls at least the wavelength, intensity and pulsation of the light.

The present disclosure is directed to providing a beauty device capable of caring various areas, and to effectively providing various functions during scalp care, and the beauty device may include a main body and a head module detachable from the main body, wherein the head module may include at least one of a plurality of protrusions, a light-emitting part, an electrode part, a sensor, and a motor, and the sensor may include a proximity sensor.

A product for use in treating a subject, incorporating a light-conversion medium which receives ambient light of broad spectrum, and emits light at one or more peak wavelengths or ranges of wavelengths (λ1, λ2, λ3) having greater intensity than corresponding intensity in the received broad spectrum ambient light. The products outlined are specifically designed for skin treatments of many different kinds, where the wavelengths chosen to have therapeutic or enhancing effects to the biological processes that occur inside or that directly affect the skin. The products can either exist as a unique treatment or be coupled with existing treatments in order to achieve an improved or differentiating result.
