  • Patent number: 12212012
    Abstract: A battery cell macromodule housing having a housing shell comprising two longitudinal walls and two end walls, the longitudinal walls being arranged perpendicular to the end walls, and the longitudinal walls and the end walls each being parallel to and spaced apart from each other so that the walls annularly enclose the interior space. The housing shell further has a plurality of positioning indentations formed on the inner sides of the walls, respectively, for positioning a battery cell perpendicular to the passage plane enclosed by the walls. The positioning indentations in the end walls are spaced further apart than the positioning indentations in the longitudinal walls.

  • Publication number: 20200289649
    Abstract: The present application relates generally to a method and a composition matter that provides a rapid and potent antimicrobial photodynamic inactivation (aPDI) of pathogenic bacteria that express high-affinity cell-surface hemin receptors (CSHRs) using Ga(III)-protoporphyrins IX (GaPpIX or Ga-PpIX). The invention provides an effective treatment option for infections of skin or body cavities that are accessible to visible-light irradiation, such as a handheld LED array emitting visible light (405 nm), especially for infections caused by Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus (MRSA), pathogenic staphylococci, Streptococcus mutans, S. pneumoniae, S. pyogenes, streptococci, corynebacteria, mycobacteria, and Bacillus anthracis.

  • Patent number: 10605699
    Abstract: A method for detecting a defective damper device of a vehicle, including the following steps: monitoring the specific damper travel values (DW) of at least two wheel carriers of the vehicle in a monitoring period (UZ), determining the specific damper speeds (DG) and the specific damper accelerations (DB) on the basis of the monitored specific damper travel values (DW) in the monitoring period (UZ), acquiring the specific damper work values (DA) on the basis of the determined specific damper speeds (DG) and on the basis of the determined specific damper accelerations (DB), generating a comparison result (VE) from a comparison of the acquired specific damper work values (DA) with one another, and generating at least one specific status signal (SS) on the basis of the comparison result (VE) for the at least two wheel carriers.
