Each pixel column includes multiple pixels arranged in an along-track direction, wherein two adjacent pixels or two adjacent pixel groups in every pixel column have a separation space therebetween. The separation space is equal to a pixel height multiplied by a time ratio of a line time difference of the rolling shutter and a frame period, or equal to a summation of at least one pixel height and a multiplication of the pixel height by a time ratio of the line time difference and the frame period. The line time difference of the TDI sensor is changeable without changing the separation space.

  • Publication number: 20220143903
    Abstract: A method of additive manufacturing a part via vat photopolymerization (VPP) includes irradiating a first material through a first transparent wall of a first material tank and forming a first section of an nth layer of the part on a platform, positioning the platform with the first section of the nth layer in a second material tank with a distance between the first section of the nth layer and a second transparent wall, and irradiating a second material such that a second section of the nth layer of the part is formed on the platform adjacent to the first section of the nth layer. The method repeats forming first and second sections of additional layer until a predetermined number of total layers are formed. Positioning the first and second sections with a distance between the second and first transparent walls, respectively, inhibits crashing during forming of the part.

  • Publication number: 20220104346
    Abstract: Printed circuit boards (PCB) used to mechanically and electrically connect electrical components within an electronic device. Thin printed circuit boards (PCB) may be desirable to manufacturers and users of electronic devices. Accordingly, a process for manufacturing a printed circuit board may involve manufacturing a thin bilayer dielectric. The process may involve applying a first non-conductive layer to a metal substrate, and curing the first non-conductive layer to a C-stage resin layer that is fully cross-linked layer in a clean environment. In turn, a B-stage layer that is partially cured may be applied to the C-stage resin layer. Using a hot press, one or more metal traces may be pressed onto the B-stage layer. The B-stage resin layer may be fully cross-linked and integrated with the C-stage resin layer after lamination of the one or more metal traces and the B-stage resin layer.
