  • Patent number: 11467415
    Abstract: A system to provide a multi-image head up display (HUD) in a vehicle includes a fixed mirror to project a far-plane image at a first distance from an occupant of the vehicle. Control of a position of display of the far-plane image is based on an eye height position of the occupant. The system also includes a rotatable mirror to project a near-plane image at a second distance, closer than the first distance, from the occupant. Control of a position of display of the near-plane image is based on a manual adjustment of a rotational angle of the rotatable mirror by the occupant. Processing circuitry automatically adjusts the position of display of the far-plane image based on inferring the eye height position of the occupant from the rotational angle of the rotatable mirror that controls the display of the near-plane image.

  • Patent number: 11462723
    Abstract: Presented are electrochemical devices with copper-free electrodes, methods for making/using such devices, and lithium alloy-based electrode tabs and current collectors for rechargeable lithium-class battery cells. A method of manufacturing copper-free electrodes includes feeding an aluminum workpiece, such as a strip of aluminum sheet metal, into a masking device. The masking device then applies a series of dielectric masks, such as strips of epoxy resin or dielectric tape, onto discrete areas of the workpiece to form a masked aluminum workpiece with masked areas interleaved with unmasked areas. The masked workpiece is then fed into an electrolytic anodizing solution, such as sulfuric acid, to form an anodized aluminum workpiece with anodized surface sections on the unmasked areas interleaved with un-anodized surface sections underneath the dielectric masks of the masked areas.
