  • a body scale to measure the body weight, using other separate devices measuring the heart rate and/or blood pressure and/or to make measurements of other body characteristics such as respiratory rate or body temperature.
  • body characteristics such as blood pressure and heart rate, are of permanent continuous interest and are usually measured in the mornings shortly after getting up from the night rest.
  • the morning routine usually takes a significant part of the day.
  • the additional actions of measuring body characteristics prolong the morning routine.
  • these additional actions require getting up earlier.
  • a sanitary mirror device comprising:
  • the sanitary mirror device further includes a sensor unit configured to obtain a body characteristic of an individual which is presently located (standing, sitting) in front of the mirror element.
  • a sensor unit configured to obtain a body characteristic of an individual which is presently located (standing, sitting) in front of the mirror element.
  • the display unit may be integrated with the mirror element so that a display area of the display unit is embedded or directly abuts to the mirror plane.
  • the display area may be formed as a semi-transparent layer embedded in or neighboring the mirror plane, so that when the display unit is deactivated the display area is fully reflective, particularly as reflective as the mirror plane itself.
  • the sanitary mirror device includes a sensor unit that allows contactless measuring of body characteristics using electromagnetic radiation such as radar, visible light, or infrared light based measurements.
  • the sensor unit may comprise a radar sensor unit configured to perform a Doppler radar measurement to detect the body characteristics data.
  • the body characteristics comprise a heart rate, a respiratory rate, and/or blood pressure.
  • the radar sensor unit may have a radar sensor and an analyzing unit to process radar signals, wherein the radar unit is configured to provide radar signals and comprise at least one antenna, wherein the antenna is provided as one of a part of a frame circumventing the mirror plane, an area of a metal layer forming the mirror plane which is galvanically isolated or any other configuration where the radar radiation is not blocked or distorted by a metal layer of or in the mirror element.

  • the display area of display unit 3 is arranged behind a semi-transparent reflective layer.
  • the semi-transparent layer is at least provided at the portion of the mirror plane.
  • display unit 3 is deactivated the display area is black and does not emit any light. Due to the semi-transparent layer, the mirror plane is continuously reflective even in the portion of the mirror plane behind which the display area is located. Therefore, the display area acts like the rest of the mirror plane.
  • display unit 3 when display unit 3 is activated it allows displaying information to a user in front of the mirror element 2.
  • the mirror element 2 is formed by a glass screen which is coated with a metal layer on its backside wherein in the portion of the mirror plane where the display unit is arranged the metal layer is thinned to make the metal layer semi-transparent so that an image presented by the display unit 3 shines through the semi-transparent metal layer.
  • the sanitary mirror device 1 may include a sensor unit 4 with one or more sensors to obtain sensor information.
  • the sensor unit 4 will be particularly configured to obtain body characteristics of an individual being present in front of the mirror element 2 and to display the body characteristics or information related thereto to immediately inform the individual while the individual is using the mirror device e.g. to check their outer appearance.
  • the sensor unit 4 may comprise a radar sensor unit 41.
  • the radar sensor unit 41 has a radar unit 41a and an analyzing unit 41b which are configured to performs a Doppler radar measurement to obtain a micro-motion radar signal of the individual's body.
  • the micro-motion radar signal can be analyzed in the analyzing unit 41b to obtain a heart rate and/or a blood pressure and/or a respiratory rate and the like.
  • Methods for determining the above body characteristics using Doppler radar measurements are well known in the art as indicated in the introduction and are not further explained herein.
  • the radar unit 41a can be of a single antenna or dual antenna type.
  • a dual antenna type radar unit 41 has a transmitting antenna 41c and a receiving antenna 41d which allows the radar unit to obtain a Doppler radar signal which can be analyzed in the analyzing unit 41b.
