An apparatus for obtaining images for use in determining one or more properties of skin of a subject, the apparatus comprising an image sensor unit for generating an image of a skin sample, wherein the skin sample corresponds to an area of skin of the subject within a field of view, FOV, of the image sensor unit when the skin of the subject is spaced a predetermined working distance from the image sensor unit; a first light arrangement comprising one or more light sources for illuminating the skin of the subject; and a second light arrangement comprising one or more light sources for illuminating the skin of the subject. The one or more light sources in the first light arrangement are spaced from the image sensor unit and arranged such that light emitted by the light sources in the first light arrangement that is specularly reflected by a skin sample at the predetermined working distance is incident on the image sensor unit, and the one or more light sources in the second light arrangement are spaced from the image sensor unit and arranged such that light emitted by the light sources in the second light arrangement that is specularly reflected by a skin sample at the predetermined working distance is not incident on the image sensor unit.

Obtaining images for use in determining one or more properties of skin of a subject

A skin treatment device provides feedback to a user relating to the force or pressure they are applying. In addition to the feedback provided for indicating that the pressure is too high, correct, or too low, there is a further feedback type when the force or pressure is below a lowest threshold value, indicating that there is no contact between the skin and the device. Providing the same feedback information when the user is applying a too low pressure as when the user has deliberately released the device from contact with the skin is thereby avoided.

Skin treatment device and method of controlling a skin treatment device

The present invention relates to a device for skin parameter measurement, comprising a housing structure () defining an interior cavity () and a first opening () at a skin contact end () of the interior cavity (), a movable part () connected to the housing structure () via an elastic connecting arrangement (), the movable part () being movable with respect to the housing structure () and configured to protrude the skin contact end () through the first opening () of the housing structure when no external force is applied to move the movable part () with respect to the housing structure, the movable part () further comprising a second opening (), an optical sensing unit () for performing measurement of a first skin parameter when the device is in contact with a skin surface, the optical sensing unit being provided within the interior cavity of the housing structure and comprising an illuminating unit (A) for illuminating the skin surface by emitting light through the second opening () of the movable part and an imaging unit (B) for receiving light reflected by the illuminated skin surface, and an electrical sensing unit () for measuring a second skin parameter, wherein the electrical sensing unit () is arranged at a front end section of the movable part () defining the second opening ().

An electric shaver having a shaving unit and a sensor with a first sensor unit fixed to a main body and a second sensor unit fixed to a sensor unit carrier, for indicating a distance between the sensor units. The shaving unit and the sensor unit carrier are suspended to the main body for displacement along a z-axis between a rest position and a pushed-in position in response to a pushing force exerted onto a shaving face of the shaver. The first and second sensor units are located in positions offset from the z-axis over a distance (d) in an x-direction. An anti-tilting guide is provided for guiding the sensor unit carrier against tilting about a y-axis.

A radiation grill unit () comprises (i) a food support unit (), (ii) a radiation unit () that includes a reflector () (with reflector opening ()) hosting an IR radiation heater (), wherein the radiation unit () is configured to provide IR radiation () in a direction of the food support unit (), and (iii) a radiation grill unit cavity () configured to host a drip tray (). A radiation unit housing includes a convection channel between (i) a back side of the reflector, opposite a front side that reflects IR radiation in the direction of the food support unit, and (ii) an inner surface of the radiation unit housing. The housing further comprises a lower opening below a lower part edge of the reflector and an upper opening above an upper part edge of the reflector to define a lower end and an upper end, respectively, of the convection channel.

Radiation grill

A radiation grill unit () comprises (i) a food support unit () with bars (), (ii) a radiation unit () that includes a reflector () (with reflector opening ()) hosting an IR radiation heater (), wherein the radiation unit () is configured to provide IR radiation () in a direction of the food support unit (), and (iii) a radiation grill unit cavity () configured to host a drip tray (). The drip tray is configured in the radiation grill unit cavity below a lower part edge of the reflector and out of a line of sight of direct IR radiation from the IR radiation heater. The drip tray further comprises a drip tray face and at least one drip tray reservoir configured at a side edge of the drip tray in a location that does not receive direct IR radiation, and configured to store a lipid comprising liquid.

The invention provides a radiation grill unit () comprising (i) a food support unit (), for instance with bars (), (ii) a radiation unit () comprising a reflector () (with reflector opening ()) hosting an (electrical) IR radiation heater (), wherein the radiation unit () is optionally configured to provide IR radiation () in a direction of the food support unit (), and (iii) a radiation grill unit cavity () configured to host a drip tray () (with edge ()).
