  • Patent number: 10752498
    Abstract: A method for manufacturing a micromechanical component including a substrate and a cap which is joined to the substrate, and, together with the substrate, encloses a first cavity, a first pressure prevailing and a first gas mixture having a first chemical composition being enclosed in the first cavity. In a first step, an access opening connecting the first cavity to surroundings of the micromechanical component being formed in the substrate or in the cap. In a second step, the first pressure and/or the first chemical composition in the first cavity being set. In a third step, the access opening being sealed by introducing energy or heat into an absorbing portion of the substrate or the cap with the aid of a laser, a reversible getter for further setting the first pressure and/or the first chemical composition being introduced into the first cavity chronologically prior to the third step.

  • Publication number: 20200198966
    Abstract: A micromechanical device that includes a silicon substrate with an overlying oxide layer and with a micromechanical functional layer lying above same, which extend in parallel to a main extension plane, a cavity being formed at least in the micromechanical functional layer and in the oxide layer. An access channel is formed in the oxide layer and/or in the micromechanical functional layer which, starting from the cavity, extends in parallel to the main extension plane and in the process extends in a projection direction, as viewed perpendicularly to the main extension plane, all the way into an access area outside the cavity. A method for manufacturing a micromechanical device is also described.

  • Publication number: 20200063335
    Abstract: A thermally-conductive material includes: a textile fabric; and a graphite-containing, thermally-conductive coating, in which graphite is present in a proportion of 5 wt % to 50 wt % relative to a total weight of the thermally-conductive material. The thermally-conductive material has a flow resistance of 60 Pa*s/m to 400 Pa*s/m. In an embodiment, a proportion of graphite in relation to the thermally-conductive coating is more than 50 wt %.

  • Patent number: 7574190
    Abstract: The present invention relates to a method and an electronic circuit for processing at least two at least partially correlated output signal streams of a mixer, the mixer having at least two signal inputs and at least two electric signal outputs. In order to provide a method and a device or an electronic circuit which enables the correlated signal portions of the output signals of a mixer to be separated from the uncorrelated signal portions undelayed, it is proposed according to the invention that the difference of the output signal streams of the mixer is formed pairwise directly and during the readout of the signal streams and that the circuit has an apparatus for the instantaneous formation of the difference between the signal streams of two mixer outputs in each case.

  • Patent number: 7361883
    Abstract: The present invention relates to a photonic mixer device with a photosensitive layer, at least two modulation gates (3, 4, 103, 104, 203, 204, 303, 304, 403, 404) and at least two readout electrodes (1, 2, 101, 102, 201, 202, 301, 302, 401, 402, 501, 502, 601, 602) connected to the photosensitive layer, the modulation gates (3, 4, 103, 104, 203, 204, 303, 304, 403, 404) being able to be connected to a modulation device which raises and lowers the potential of the modulation gates relative to one another and relative to the preferably constant potential of the readout electrodes corresponding to a desired modulation function.

  • Publication number: 20050237593
    Abstract: The present invention relates to an electromagnetic mixing system for receiving and processing modulated electromagnetic signals, with a signal detector made from a semiconductor material for receiving and converting electromagnetic radiation into an electric measured value and with at least one modulation input modulating the reception of the signal detector, and also with at least two accumulation electrodes which are connected to output electronics at the output of which a mixture of the received signal and at least one modulation signal applied at the modulation input is effectively provided as electric signal. The present invention also relates to a method for operating such an electromagnetic mixing system, the electromagnetic signals striking the signal detector producing charge carriers which, depending on the at least one modulation signal, are conducted at least partially alternately to the at least two different readout electrodes.
