Abstract: A hull mounted, steerable marine drive system having trim actuation is both steerable through 360 degrees and is trimmable. The marine drive system includes a watertight enclosure assembly for sealing the hull, which is adapted for keeping much of the marine drive system from being exposed to water. The enclosure includes a gasket flange plate, a retention plate and a folded gasket. The gasket flange plate closely follows the contour of the hull and enhances the hydrodynamic and wake performance of the present marine drive system. Further, marine drive system includes a forward-neutral-reverse (FNR) transmission assembly, a drive unit assembly having a trimmable upper unit and a steerable lower unit, a steering actuator assembly, a trim actuator assembly, and, preferably, trim foils for providing enhanced negative and positive trim and for providing enhanced positive and negative lift.

Abstract: A system for aligning a bed of an imaging system with an imaging plane. The system includes a laser device which generates a laser beam and a target element having a target detecting surface. The system also includes a reflective element which receives the laser beam. The reflective element includes a reflective detecting surface for detecting a first position of the laser beam. A first parameter of the bed is adjusted until the laser beam is positioned on a first center portion of the reflective detecting surface. In addition, the laser beam is reflected to the target detecting surface to detect a second position of the laser beam. A second parameter of the bed is adjusted until the laser beam is positioned on a second center portion of the target detecting surface to orient the bed substantially perpendicular to the imaging plane.
