  • Patent number: 12235179
    Abstract: Optical tactile sensors are provided that include a scaffolding structure, a transparent elastomer material covering at least an end portion of the scaffolding structure, and one or multiple cameras situated on the end portion of the scaffolding structure and embedded within the transparent elastomer material, wherein the one or multiple cameras are situated so as to provide an extended, e.g., up to 360°, field of view about the end portion of the scaffolding structure.

  • Publication number: 20240249426
    Abstract: A method for dynamic modeling and manipulation of multi-object scenes is described. The method includes using object-centric neural implicit scattering functions (OSFs) as object representations in a model-predictive control (MPC) framework for the multi-object scenes. The method also includes modeling a per-object light transport to enable compositional scene re-rendering under object rearrangement and varying lighting conditions. The method further includes applying inverse parameter estimation and graph neural network (GNN) dynamics models to estimate initial object poses and a light position in the multi-object scene. The method also includes manipulating an object perceived in the multi-object scene according to the applying of the inverse parameter estimation and the GNN dynamics models.

  • Publication number: 20140049102
    Abstract: An electronic control unit (ECU) assembly is provided, which includes a covering part, one or more metal oxide semiconductor field effect transistors (MOSFETs) (1), a substrate and an ECU main body. The covering part includes a lid element (3) having latch parts (6); the lid element (3) is secured onto the ECU main body via the latch parts (6); and the MOSFETs (1) are arranged between the lid element (3) and the substrate (9). The covering part further includes a middle element, which is in tight contact with and is elastically pressed against the MOSFETs (1), such that the MOSFETs (1) are brought into tight contact with the substrate. Thereby, the MOSFETs (1) are reliably fixed in the ECU assembly. A vehicle including the ECU assembly is also provided.
