Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a cutting unit for a hair-cutting device. A cutting unit 14 is provided that comprises a tapered stationary guard blade 18 and a reciprocating cutter blade 16 in which the stationary guard blade is arranged to be moved perpendicular to the reciprocal motion of the cuter blade to allow the selection of different length settings. The guard blade may be biased to a minimal length setting. The stationary guard blade may be configured to be actuated by a user to allow a stepless change of the cutting length, when the stationary guard blade is pushed from its biased start position to the other end position.

Abstract: An electric shaver having a shaving unit (3) and a sensor (15) with a first sensor unit (16) fixed to a main body (2; 202; 302) and a second sensor unit (17) fixed to a sensor unit carrier (22; 222; 322), for indicating a distance between the sensor units (16, 17). The shaving unit (3) and the sensor unit carrier (22; 222; 322) are suspended to the main body (2; 202; 302) for displacement along a z-axis between a rest position (22) and a pushed-in position (22?) in response to a pushing force exerted onto a shaving face (11) of the shaver (1). The first and second sensor units (16, 17) are located in positions offset from the z-axis over a distance (d) in an x-direction. An anti-tilting guide (24-27; 124; 224, 226; 326, 328) is provided for guiding the sensor unit carrier (22; 222; 322) against tilting about a y-axis.
