Abstract: Prompting a trained artificial intelligence (AI) model(s) to output photoreal synthetic content in real-time is described. In some examples, one or more AI models are trained using sequential video frames as training data to obtain one or more trained AI models configured to generate temporally-coherent output data. In an example process, user-provided prompt data representing a prompt provided by a user is received, output data representing synthetic content is generated using the trained AI model(s) based at least in part on the user-provided prompt data, and video content featuring the synthetic content is caused to be displayed on a display based at least in part on the output data. In some examples, the output data is provided to the trained AI model(s) as part of a feedback loop to generate further output data as part of a real-time, iterative prompting system.

Abstract: The present invention relates to an edge-emitting laser diode which has a semiconductor heterostructure consisting of at least one active layer or layer sequence (4) between two wave-guiding semiconductor layers or layer sequences(3, 5), which extend between a rear (9) and a front facet (10) of the laser diode. Between the rear (9) and the front facet (10), the two wave-guiding semiconductor layers or layer sequences (3, 5) each have one or more modified portions (14), in which vertical leakage currents from the active layer or layer sequence (4) are reduced or suppressed by a design of the two wave-guiding semiconductor layers or layer sequences (3, 5) that is modified in comparison with the remaining portions. The modified portions (14) are arranged in positions in which undesired excessive temperature increases would occur if the laser diode were operated without said reduction or suppression of the vertical leakage currents.

Latent space manipulation and neural animation may be used with the trained machine learning model(s) to generate instances of the synthetic face, and the instances of the synthetic face can be used to create altered video content featuring the subject with the synthetic face making the mouth-generated sound.

Abstract: A method for operating a drive device for a motor vehicle is provided, wherein the drive device has an electric machine which is electrically connected to a DC power source via an inverter controlled by means of pulse width modulation. The pulse width modulation is performed depending on a predetermined duty cycle. When the duty cycle that is less than a threshold value, a continuous pulse width modulation is used to control the inverter. The pulse width modulation is switched to a discontinuous pulse width modulation when the threshold value is exceeded. A motor vehicle and a drive device for a motor vehicle are also provided.

Abstract: A metal seal for a flap valve, is disclosed which has a valve housing with a flow channel, in the flow cross-section of which a valve disk is disposed such that it can be swiveled around a swivel axis between an open position and a shutoff position. The seal has sealing elements, which can be pressed against one another, and which are disposed on the outer circumference of the valve disk and on the inner circumference of the valve housing, and they have at least one annular metal sealing lip, which in the shutoff position bears with elastic preload on an oppositely situated, likewise annular metal mating sealing face. To prevent damage to outer components, the metal sealing lip is produced in an additive method from metal materials having shape, cross-sectional geometry and/or alloy adapted to the different circumferential regions of the metal sealing lip.

Abstract: Flap valves include a valve housing and a flap disc in a flow channel of the valve housing. The flap disc can be pivoted between an open position and a closed position. The flow channel on its outer circumference includes a sealing lip arrangement, which has two elastic sealing lips arranged at a distance from each other in the direction of flow. With the valve disc in the closed position, the sealing lips bear under elastic prestress against the sealing surface of the valve disc to form a seal and thereby form an annular cavity surrounding the sealing surface of the valve disc. Further, with the flap disc in the closed position, the passage of fluid from the high-pressure side in the flow channel to the low-pressure side of the flow channel prevented due to the cross-sectional areas of the two sealing lips of the sealing lip arrangement being inclined or bent towards the inside of the annular cavity.
