Abstract: The present invention relates to a sensor configuration (1) for non-invasive measurement of parameters of a body tissue with a sensor unit (10) and a sensor mat (12) for detachable placement of the sensor configuration (1) on a body surface (20). Furthermore the sensor unit (10) of the sensor configuration (1) is connectible to a contact head (16), which is designed for electrical contacting of the sensor unit (10) and for supply of light from a light source to the sensor unit (10), the sensor unit (10) being designed as a flexible printed circuit board with optical components, at least comprising a light detector device (2), in order to detect light that is emitted into the body tissue and has passed through the latter, a first contact means (30) and conducting tracks (5) for operative connection of the sensor unit (10) to the contact head (16).

Abstract: The invention relates to a solar box (1) with a connection box (2) and at least one extension module (3, 20), which can be operatively connected to the connection box (2) via a first and a second connector part (9, 10) of a standardized interface (8). The connection box includes a connection shaft (5), into which contacts (7) lead from a shaft wall (11). The contacts (7) and the standardized interface (9) are arranged on the same shaft side.
