Latest Patents
Riggs' latest patents include the "Angular adjustment of MEMS torsion oscillator scanner" and "Laser scanner having reduced air currents." The first patent describes an apparatus for aligning a scanner assembly in a laser scanning unit for an image forming device. In this invention, a MEMS torsion oscillator is attached to a spherical base that fits into a socket in the laser scanning unit. The pivotal center of the scanner aligns with the center of the spherical base, ensuring that the scanner remains stationary during alignment. Various methods, such as adhesives and spring-biased adjustment screws, maintain this alignment without obstructing the laser beam used for calibration.
The second patent focuses on improving the operation of an electrophotographic printer. This method involves enclosing the torsion oscillator of the laser scanning unit in a closed compartment. This design minimizes stray air currents around the torsion oscillator, thereby enhancing the printer's overall performance.
