  • Patent number: 12189299
    Abstract: A digital lithography system includes adjacent scan regions, exposure units located above the scan regions, a memory, and a processing device operatively coupled to the memory. The exposure units include a first exposure unit associated with a first scan region and a second exposure unit associated with a second scan region. The processing device is to initiate a digital lithography process to pattern a substrate disposed on a stage in accordance with instructions. The processing device is to further perform a first pass of the first exposure unit over a stitching region at an interface of the first scan region and the second scan region at a first time. The processing device is to further perform a second pass of the second exposure unit over the stitching region at a second time that varies from the first time by less than forty seconds.

  • Patent number: 11855388
    Abstract: A floating electrical connector includes a housing with a tubular portion. An axis is defined in a center of the tubular portion. Several floating terminals are arranged around the axis and are partially connected. Each floating terminal has an inner terminal sheet on an inner side and a spring structure on an outer side. Each spring structure is connected to one of the inner terminal sheets. A portion of the inner terminal sheet is inserted into the tubular portion and arranged along an inner peripheral surface of the tubular portion. The portion of each inner terminal sheet located in the tubular portion has an electronic contact bulging inward. Several external pins are electrically connected around the floating terminals. When a conductive pin is inserted into the tubular portion, the spring structures could elastically deform, allowing the tubular portion to adapt to a horizontal deviation or a skew deviation of the conductive pin, providing a greater tolerance for alignment deviations.
