Abstract: A mirror device (1) which can be simultaneously used for display purposes, based on e.g. an LCD display (5) with a polarizing mirror (6) placed in front of it. The polarizing mirror (2) has the characteristics that it does not disturb the transmission of the light from the display (5), but does reflect the light from outside the area of the screen. The polarizing mirror (2) is embedded in a conventional mirror (4,8).

Abstract: The invention relates to a system for identifying a person, comprising means for detecting a distribution of pressures, exerted by at least one foot (20) of the person on a surface, means for storing data of a number of persons, the data comprising a detected pressure distribution pattern (A,B,C) and an associated person identification code (X,Y,Z), and means for comparing a detected pressure distribution pattern (A) with stored pressure distribution patterns (A,B,C) until a match of pressure distribution patterns is found. The invention further relates to a method of identifying a person. The person is identified on the basis of a distribution of pressures, exerted by at least one of the feet (20) on a surface. When the user has placed one or both feet (20) on said surface, said distribution of pressures is detected.

Abstract: An electrode structure for use with a monitoring system. A thin flexible body of an electrode material comprising conductive rubber is provided with projections extending externally to a working surface. According to this construction of the working surface of the electrode only the projections make a contact to the recipient's skin. When the projections are provided with a small cross-section, the constant electrode-skin contact is ensured due to the resiliency of the electrode material.
