Latest Patents

One of Hartmann's latest inventions is a sensor unit designed for detecting the wetting of a window. This invention relates to a sensor unit that utilizes signals from a condensation sensor to control air conditioning, heating, and ventilation units. Conversely, signals from a rain sensor are employed to manage windshield wipers or washing units in vehicles. The sensor unit, which consists of two sensors, is strategically placed on the interior of the window. In a preferred variant, both sensors are connected to a common switchable evaluation unit, allowing for the mutual evaluation of their signals. This enables the detection of both incipient condensation on the interior of a vehicle window and the wetting of the exterior due to rain. An improvement of this invention integrates both sensors into a single sensor module.

Another significant patent involves a sensor for detecting condensation, which is utilized in sensor modules. This invention addresses the critical influencing variables for comfort in controlled heating and air conditioning units. It aims to prevent incipient condensation on windshields and other windows. The sensor module employs a capacitative thin-layer sensor, complemented by a thermopile for window temperature determination. However, Hartmann's innovative approach eliminates the need for direct temperature measurement by ensuring that the sensor is in direct thermal contact with the window through a metal plate. This design enhances the efficiency and accuracy of the sensor module.
