  • Publication number: 20240140352
    Abstract: A seatbelt of a vehicle includes a buckle tilt mounting device for a tongue plate coupled with a seatbelt webbing restraining an occupant seated in a vehicle seat. The buckle tilt mounting device includes a buckle assembly having a buckle and a buckle cable, and further includes a pre-tensioner system having a housing, a driving member, and a pre-tensioner cable. When the pre-tensioner system is actuated at a time of a vehicle collision or at a time a vehicle collision is anticipated, the driving member retracts the pre-tensioner cable inside the housing such that the buckle assembly is rotatably moved and configured to reduce submarining load on the occupant.

  • Publication number: 20240135856
    Abstract: An electronic device may include an electronic display having multiple display pixels that display an image based on dithered image data. The electronic device may also include image processing circuitry that generates the dithered image data based on input image data and a threshold gray level that is greater than one. Generating the dithered image data may include replacing each gray level of the input image data that is less than the threshold gray level with either a zero gray level or the threshold gray level according to a dither pattern.

  • Publication number: 20240116837
    Abstract: A system and a process for dimerizing cyclopentadiene (CPD) including producing a C6+C7 rich bottoms stream and a C5 rich side draw from a debutanizer, where the C5 rich side draw and at least a portion of the C6+C7 rich bottoms stream are directed to a dimerizer where the CPD is thermally dimerized to dicyclopentadiene (DCPD). DCPD is more stable than CPD and thus safer to handle.

  • Publication number: 20240085706
    Abstract: An electronic device may include a display module that produces light having an image, a lens that directs the light to a waveguide, and a waveguide that directs the light to an eye box. The lens may produce a foveated image in the light by applying a non-uniform magnification to the image in the light. The non-uniform magnification may vary as a function of angle within a field of view of the lens. This may allow the foveated image to have higher resolution within the central region than in the peripheral region. Performing foveation using the lens maximizes the resolution of images at the eye box without increasing the size of the display module. Control circuitry on the device may apply a pre-distortion to the image that is an inverse of distortion introduced by the lens in producing the foveated image.

  • Publication number: 20230314672
    Abstract: A method for introducing a customized variation of a geometric parameter in a nanoscale pattern on a substrate. A nanoscale precision programmable profiling process is conducted on one or more regions of the substrate with the nanoscale pattern, where the nanoscale precision programmable profiling process is used to deposit a profiling film with a thickness profile that is a function of the customized variation of the geometric parameter in the nanoscale pattern. The method further comprises conducting a plasma etch process of the profiling film and the material of the nanoscale pattern that converts the thickness profile of the profiling film into the customized variation of the geometric parameter in the nanoscale pattern, where the customized variation is a function of the thickness profile of the profiling film.

  • Publication number: 20230141346
    Abstract: An infused undergarment device for use as a delivery device for colonizing the vagina with Lactobacillus in patients who test positive for or report symptoms of vaginitis. The infused undergarment employs a sponge impregnated with Lactobacillus crispatus Freeze Dried Powder. The sponge, having channels to direct the powder, is held in place by a mesh fabric sewn into the groin portion of the undergarment, which allows the c n ay delivery of the powder, The undergarment may also be used to help maintain normal flora of the vagina in the absence of symptoms in a prophylactic manner to prevent future infection. The undergarment is sealed in an opaque aluminum foil package to prevent light and environment air from degrading effectiveness.
