  • Publication number: 20240045595
    Abstract: A processing device in a memory sub-system determines whether a media endurance metric associated with a memory block of a memory device satisfies one or more conditions. In response to the one or more conditions being satisfied, one or more read margin levels corresponding to a page type associated with the memory device are determined. A machine learning model is applied to the one or more read margin levels to generate a margin prediction value based on the page type and a wordline group associated with the memory device. Based on the margin prediction value, the memory device is assigned to a selected bin of a set of bins. A media scan operation is executed on the memory device in accordance with a scan frequency associated with the selected bin.

  • Publication number: 20240049407
    Abstract: A pedestal has two sides that are opposite one another and to which various charging boxes can be mounted and electrically connected. For instance, the pedestal can have the same charging boxes mounted to the two sides and electrically connected with a power system upon which the pedestal is positioned. Instead, two different charging boxes can be mounted to the two sides. Importantly, either or both charging boxes can be easily removed by appropriate personnel and alternatively replaced with other charging boxes if, for instance, the market for needing specific electrical charging has changed or if the population of electrical vehicles needing electrical charging has grown in a new direction, by way of example.

  • Publication number: 20240042851
    Abstract: A head-up display for displaying graphics upon a windscreen of a vehicle includes a graphic projection module for generating images upon the windscreen of the vehicle, a user input device for receiving user-generated commands created by a user of the vehicle, and one or more controllers in electronic communication with the graphic projection module and the user input device. The controller executes instructions to instruct the graphic projection module to generate a luminance adjustment graphic, where the luminance adjustment graphic includes an adaptive color palette graphic including two or more colors. The controller receives, from the user input device, a user-generated luminance input indicating a change in a level of luminance in a selected color, where the change in the level of luminance in the selected color is selected by the user to discern differences between the two or more colors caused by a color vision deficiency.
