摘要： The invention relates to a device for measuring at least one gaseous or solid material in at least one measurement volume at a stationary measurement station, wherein: a light source and at least one detector are provided, and at least one main primary beam can be emitted from the light source to at least one beam splitter unit; the at least one beam splitter unit is disposed at a first distance from a first reflection region of a reflection unit, and the beam splitter unit splits the main primary beam into at least one first partial beam oriented through the measurement volume toward the first reflection region and at least one secondary primary beam oriented in a different direction than the main primary beam; at least one deflecting unit is disposed at a second distance from a second reflection region, and the at least one secondary primary beam can be directed to the deflecting unit by means of the beam splitter unit and the at least one secondary primary beam can be directed, as a second partial beam, through the at least one measurement volume toward the second reflection region by means of the deflecting unit; and each of the at least one measurement volume is disposed between the beam splitter unit and/or the deflecting unit and the associated reflection regions and is at least partly delimited by the beam splitter unit and/or the deflecting unit and the associated reflection regions. According to the invention, the first reflection region directs the first partial beam, as a first return beam, through the at least one measurement volume to the at least one detector, the second reflection region directs the second partial beam, as a second return beam, through the at least one measurement volume to the at least one detector, and the at least one detector measures a light property of each return beam, said light property characterizing the at least one gaseous or solid material.

摘要： Various aspects of the present disclosure are directed to a method for ascertaining the state of health of a secondary battery. In one example embodiment, the method includes making a first estimation for the state of health by an observer, using an aging prediction model to ascertain a second estimation for the state of health, the aging prediction model being parameterized on the basis of the first estimation for the state of health. The first or second estimation of the state of health, or a combination of the first and second estimation of the state of health, is used as the state of health of the secondary battery.

摘要： In order to simplify the execution of test drives with a test vehicle which is controlled by a test driver so as to complete a test case, according to the invention, for each test case (TFj) a start condition (SBj) is defined on the basis of at least one sensor signal (S) of a vehicle sensor of the test vehicle and stored in the memory unit together with the associated test case (TFj), wherein each start condition (SBj) defines a particular vehicle state, at least one sensor signal (S) that represents a current vehicle state is recorded by at least one vehicle sensor during the test drive, and the at least one sensor signal (S) is transmitted to a test unit, the test unit reads out the start condition (SBj) of at least one stored test case (TFj) from the memory unit and, during the test drive, the test unit checks whether the vehicle state stored for the read-out start condition (SBj) and the current vehicle state represented by the recorded sensor signal (S) match, and, if they match, the test driver completes the test case (TFj) assigned to the read-out start condition (SBj), in that said test case (TFj) is started, and the test driver is provided with the test steps (TSn) defined in this test case (TFj) for attention, and the test driver performs these test steps (TSn).

摘要： Various aspects of the present disclosure are directed to a cylinder head for an internal combustion engine. In one example embodiment, the cylinder head includes at least one spark plug having at least one earth electrode, a precombustion chamber accommodating the at least one spark plug, and a fuel channel which leads into the precombustion chamber. The fuel channel having a flow axis at an outlet that is oriented in the direction of the at least one earth electrode. An axis of rotation of the at least one spark plug has an offset with respect to the flow axis between 0 and 15% of the greatest precombustion chamber diameter.

摘要： A measuring device for metering a fluid. The measuring device includes a container with the fluid, a fluid inlet which is fluidically connected to the container, a fluid outlet which is fluidically connectable with a metering point, a metering line which connects the fluid inlet with the fluid outlet, a delivery pump arranged in the metering line, a density sensor arranged in the metering line, a flow meter arranged in the metering line, and a recirculation line which is arranged to branch off from the metering line downstream of the flow meter and to open into the container. The flow meter is arranged in a measuring unit housing which is arranged at a distance from a pump unit housing in which at least the delivery pump is arranged. The pump unit housing is detachably connected to the measuring unit housing via a connection portion of the metering line.

摘要： In order to devise a method for validating a assumed position (P1) of a vehicle, a vehicle receiver (1) receives a V2X message (3) transmitted by a transmitter (2) and determines a position (p2) of the transmitter (2) from the V2X message, wherein local environmental geodata comprising positions of a number of stationary objects (O1, O2, O3, O4) is made available, a signal path (x) of the V2X message (3) is simulated on the basis of the transmitter position (p2) taking into account the environmental geodata and the assumed vehicle position (P1), and at least one simulated physical received signal property is determined from the simulated signal path (x) and the assumed vehicle position (P1). When receiving the V2X message, at least one actual physical received signal property of the V2X message (3) is determined, and the assumed vehicle position (P1) is validated if the at least one simulated physical received signal property differs from the at least one actual physical received signal property by less than a limit value (G).
