Publication number: 20230280496Abstract: In order to detect subcooled liquid precipitation, a temperature of an object having a precipitation impingement surface is measured, and an occurrence of precipitation onto the precipitation impingement surface is determined. The temperature of the object and the occurrence of the precipitation are analyzed, and a subcooled liquid precipitation warning is output, if there is an increase in the temperature of the object below 0° C. because of the occurrence of the precipitation.Type: ApplicationFiled: May 10, 2023Publication date: September 7, 2023Inventors: Joachim Beinhorn, Christoph Peper, Herbert Windolph

Patent number: 11031519Abstract: A light receiving unit having a first energy source made up of two sub sources. A first terminal contact is formed at the upper face of the first sub source and a second terminal contact is formed at the lower face of the second sub source. The sub source has at least one semiconductor diode that has an absorption edge adapted to a first wavelength of light and the second semiconductor diode has an absorption edge adapted to a second wavelength of light which is different from the first wavelength of light, such that the first sub source generates electric voltage upon being irradiated with the first wavelength of light and the second sub source generates electric voltage upon being irradiated with the second wavelength of light.Type: GrantFiled: November 4, 2019Date of Patent: June 8, 2021Assignee: AZUR SPACE Solar Power GmbHInventors: Thomas Lauermann, Christoph Peper, Wolfgang Koestler

Patent number: 10686532Abstract: An optical receiver component, wherein the receiver component comprises a first type of partial-voltage source with a first absorption edge and a second type of partial-voltage source with a second absorption edge, and the first absorption edge lies at a higher energy than the second absorption edge. Each partial-voltage source produces a partial voltage, provided a photon flux at a specific wavelength strikes the partial-voltage source, and the two partial-voltage sources are connected in series. A first number of series-connected sub-partial-voltage sources of the first type and a second number of series-connected sub-partial-voltage sources of the second type are provided. The first number and/or the second number are greater than one, and the respective deviation of the source voltages of the sub-partial-voltage sources among themselves is less than 20% in both types. Each sub-partial-voltage source comprises a semiconductor diode with a p-n junction.Type: GrantFiled: April 20, 2018Date of Patent: June 16, 2020Assignee: AZUR SPACE Solar Power GmbHInventors: Wolfgang Guter, Daniel Fuhrmann, Christoph Peper

Patent number: 10566490Abstract: A receiver component having a number of partial voltage sources implemented as semiconductor diodes connected to one another in series, so that the number of partial voltage sources generate a source voltage, and each of the partial voltage sources has a semiconductor diode with a p-n junction, and the semiconductor diode has a p-doped absorption layer. The p absorption layer is passivated by a p-doped passivation layer with a larger band gap than the band gap of the p absorption layer, and the semiconductor diode has an n absorption layer that is passivated by an n-doped passivation layer with a larger band gap than the band gap of the n absorption layer. The partial source voltages of the individual partial voltage sources have a deviation of less than 20% from one another, and a tunnel diode is formed between each sequential pair of partial voltage sources.Type: GrantFiled: August 9, 2018Date of Patent: February 18, 2020Assignee: Azur Space Solar Power GmbHInventors: Clemens Waechter, Daniel Fuhrmann, Wolfgang Guter, Christoph Peper
