Abstract: According to one aspect, a vehicle includes a chassis, a propulsion system carried on the chassis, a control system carried on the chassis, and a components arrangement carried on the chassis. The propulsion system configured to propel the vehicle, and the control system is configured to enable the vehicle to operate autonomously. The components arrangement includes at least a frame, a panel having a surface, a wiper arrangement having at least one wiper, and a fluid distribution arrangement. The frame is configured to interface with the chassis and to support the panel, the wiper arrangement, and the fluid distribution arrangement. The fluid distribution arrangement is configured to dispense a fluid onto the surface and the wiper is configured to sweep over the surface.

Abstract: There is described a process for recording a positive or negative continuous tone color copy having the same or lower contrast than a continuous tone original image, comprising the steps of:providing a photographic element comprising a support having thereon a silver halide emulsion unit capable of forming a yellow image, a silver halide emulsion unit capable of forming a cyan image, and a silver halide emulsion unit capable of forming a magenta image, each image-forming unit having a maximum spectral sensitivity at a different wavelength of radiation, and at least one of the image-forming units having a gamma as described herein,receiving image data representing the densities of the yellow, magenta, and cyan records of the original image,modifying said image data and using it to control three exposure sources, each emitting radiation in the region of maximum spectral sensitivity for a corresponding one of the image-forming units, so that, after exposure, the recorded image density range for at least one of o

Abstract: A laser printer is disclosed which is adapted to be used for color imaging. The printer comprises three diode lasers, each of which emits at a different wavelength. Each laser beam is passed through an apodizing mask to trim the final spot size. The beams from the three lasers are combined by the use of dichroic mirrors to form one combined beam. The combined beam is shaped by two spherical mirrors and is scanned onto a receiving medium by a polygon. The receiving medium is sensitive to the infrared, and the diode lasers are selected to obtain the widest possible spectral separation in the light beams from the lasers.

Abstract: A fiber optic array is disclosed for use in an optical scanning device. The array includes a substrate and a plurality of optical fibers arranged on the substrate to form a linear array of the fibers. Each of the fibers is received in grooves in the substrate to precisely space the fibers relative to each other. Each of the fibers is adapted to receive light from a source such as a laser diode. In order to increase the packing density of the fibers in the array, the ends of the fibers are etched to decrease the cladding diameter, and the fiber ends of reduced diameter are mounted in closely-spaced parallel grooves.

Abstract: An acoustooptic deflection cell diffracts a multi-color beam into a plurality of different mono-color beams of distinct scan angles. An optical system intercepts the diffracted light beams, equalizes the differenct scan angles and realigns the beams to register at an image plane. Equalization of the scan angles may be accomplished by a prism system, while realignment may be done with a mirror system.
