A portable hair-removal apparatus (1) is provided, which includes an air-suction mechanism (10). The air-suction mechanism (10) includes a heat-generating assembly (101) and a heat-dissipation housing (102). The heat-dissipation housing (102) is provided with an air outlet (1021). The heat-generating assembly (101) is connected to the heat-dissipation housing (102) and defines at least one air inlet (1022). External air is sucked into the heat-dissipation housing (102) via the air inlet (1022), flows through the heat-generating assembly (101) to reduce the temperature thereof, and is discharged via the air outlet (1021). A short-range air-passing channel is formed by means of the cooperation of multiple components, such that the heat dissipation performance is improved, the size is further reduced by simplifying the internal structure and the portability is improved.

A skin treatment device having a treatment window for treating skin through the treatment window and a user guide to deliver a tactile feedback signal during movement in stepwise increments of the treatment window along the skin.

The present invention relates to an optical apparatus for skin treatment and to a method for controlling the optical apparatus. The optical apparatus includes a radiating part for radiating light generated in a light-generation part onto a target position of the skin, a cooling part for spraying cooling gas onto the target position to cool the surface of the skin, and a control part for controlling operations of the radiating part and cooling part. The control part controls the radiating part and the cooling part such that the radiating part radiates a first light onto the target position, the cooling part sprays the cooling gas onto the target position, and then the radiating part radiates a second light onto the target position.

A method for determining parameters for operating a light source within a photo-thermal targeted treatment system is disclosed. The method includes cooling a treatment location, administering first laser pulses at the treatment location, the first laser pulses having thermal energy below a known damage threshold, tracking skin surface temperatures at the treatment location while administering the first laser pulses, estimating a relationship between parameters for operating the light source and the skin surface temperature by fitting tracked skin surface temperature to a correlation model, determining a safe operating range for the light source to avoid thermal damage at the treatment location while still effectively targeting the chromophore, administering second laser pulses at the treatment location, the second laser pulses staying within the safe operating range for the light source, and adjusting the light source according to the tracked skin surface temperatures to stay within the safe operating range.

A temperature measurement system for measuring a temperature of a measured surface includes: 1) a first temperature sensor; and 2) a reference surface including a second temperature sensor integrated therein. The first temperature sensor includes a field of view simultaneously covering both at least a portion of the measured surface and at least a portion of the reference surface, thus is configured for simultaneously taking a first measurement of both the portion of the measured surface and the portion of the reference surface. The first measurement of the reference surface taken by the first temperature sensor is compared to a second measurement taken by the second temperature sensor for use in calibrating the first temperature sensor.

An unattended approach can increase the reproducibility and safety of the treatment as the chance of over/under treating of a certain area is significantly decreased. On the other hand, unattended treatment of uneven or rugged areas can be challenging in terms of maintaining proper distance or contact with the treated tissue, mostly on areas which tend to differ from patient to patient (e.g. facial area). Delivering energy via a system of active elements embedded in a flexible pad adhesively attached to the skin offers a possible solution. The unattended approach may include delivering of multiple energies to enhance a visual appearance.

A system for working biological tissue, the system comprising: a tool comprising a laser operable to perform at least one action of work; positioning means for positioning the tool relative to the biological tissue to perform the at least one action of work; a controller; storage storing electronic program instructions for controlling the controller; and an input means; wherein the controller is operable, under control of the electronic program instructions, to: receive input via the input means; process the input and, on the basis of the processing, control the positioning means and the tool to work the biological tissue.

The application relates to compounds having functional substituents in a specific spatial arrangement, to devices comprising same, and to the preparation and use thereof.

Resonance Raman scatter is used to differentiate in quasi-real time (QRT) surfaces bearing pathogens from adjacent pathogen-free surface regions. The fingerprint generated from pathogens on a selected surface by a 1 second pulse of 532 nm emission for approximately one second is collected and is relayed by fiber-optic to a computerized controller that determines whether the target selected surface is contaminated by pathogens or is pathogen-free. If contaminated the pathogens are eradicated by UVC radiation. This is performed by a pattern of Resonance Raman diagnostic emission and diagnostic sensor fibers. The data received by the computer is examined instantly, and should the site be diagnosed as contaminated with pathogens, UVC radiation is repeated immediately and repeated until the selected surface is read as being pathogen-free.
