Compositions and methods are provided for the sizing of paper, to enhance the quality of images printed thereon. The novel sizing compositions contain as a sizing agent a mixture of a polyacid and a polybase. When applied to a paper substrate, such as in an internal or external sizing process, the sizing compositions result in a sized paper substrate that provides high quality printed images when printed with an ink containing a reactive dye having ionizable and/or nucleophilic groups capable of reacting with the sizing agent. Images printed on a paper substrate coated with the sizing compositions of the invention are bleed-resistant, water-resistant (e.g., water-fast), and/or are characterized by an enhanced chroma and hue.

The present disclosure provides a mobile machine including a laser diode based lighting system having an integrated package holding at least a gallium and nitrogen containing laser diode and a wavelength conversion member. The gallium and nitrogen containing laser diode is configured to emit a first laser beam with a first peak wavelength. The wavelength conversion member is configured to receive at least partially the first laser beam with the first peak wavelength to excite an emission with a second peak wavelength that is longer than the first peak wavelength and to generate the white light mixed with the second peak wavelength and the first peak wavelength. The mobile machine further includes a light detection and ranging (LIDAR) system configured to generate a second laser beam and manipulate the second laser beam to sense a spatial map of target objects in a remote distance.

A scanning device for biological slides is provided, which can be operated in an interactive routine mode as well as in an unsupervised high speed automatic mode. In the first case, typical components, which the pathologist is used to operating manually, such as the microscope, the stage and the focus, and which have to be motorized for the automatic unsupervised system mode, are configured to simulate manual use, operation, and response. A non-interlaced area scan camera supports the interactive selection and acquisition of individual images in the manual mode, as well as the continuous high-speed scan motion for the rare event detection and virtual slide scan applications of the system. Due to the particular requirements to accommodate both operational modes, methods are described for constructing the virtual slide out of image tiles with varying overlap areas in the x- and y-directions.

According to example configurations herein, a downstream video processor operates in conjunction with an existing consumer-operated tuner system. The downstream video processor system can be an add-on system disposed in a communication link between the consumer-operated tuner system and a remote video playback device such as a hi-definition television. In lieu of processing video data locally in the set-top box, the consumer-operated tuner system can transmit the video data to the downstream video processor for processing. The downstream video processor in the communication link can be configured to provide enhanced video processing services (e.g., better resolution, higher frame rate rates, enhanced signal to noise ratio, enhanced color quality, 3-D graphics, etc.) with respect to video processing services supported by an upstream video decoder in the consumer-operated tuner system.

The invention relates to an infrared and visual pseudo-color image fusion and enhancement method. The method comprises the following steps: performing advanced partition treatment on infrared images to acquire three different area characteristics of background information, target information and cold target information, preserving characteristic information, performing pseudo-color fusion on the infrared and visual images under a color space of YUV to acquire pseudo-color fusion images, and then performing color transfer and color enhancement treatment on the pseudo-color fusion images by using a given color reference image to acquire final fusion images. The method can cause the final fusion images to have more area characteristic information, and furthest promote the color quality of the fused images at the same time of ensuring the instantaneity of a system.

A printing system is linearized automatically using measurements made with a simple optical sensor, such as a line sensor, that is onboard the system. The printing system itself is for forming images on plural printing media. Because the optical sensor is not a calorimeter or even a true densitometer, the sensor requires calibration, preferably based upon measurements using real inks. In the past it has been considered a requirement that such calibration be performed separately using each of the print media that was to be used for printing images. Linearization according to the invention, however, refers to a single calibration of the sensor, that calibration being used in common for essentially all media—even though the single calibration is performed with respect to exclusively a single one of the plural media.

The invention relates to a nanostructured product with a structurally coloured surface. The nanostructured product includes a substrate with a nanostructured surface having nano-sized pillars or holes arranged in a periodic pattern and extending into or out from the substrate. The bottoms of the nano-sized holes or the tops of nano-sized pillars are provided with metal layers electrically isolated and distanced from a base surface of the nanostructured surface. A transparent or translucent protective layer covers the substrate and the metal layers.

A light source sequentially emits lights generated by at least three light emitting elements each emitting a different primary color to generate an image. Each light emitting element has a duty cycle in a lighting period, which may be an image frame period. A sequence scheme is provided for alternatingly driving different ones of the light emitting elements. The light emitting elements are driven in accordance with the sequence scheme at least two times in the lighting period, while maintaining the duty cycle for each light emitting element. In the sequence scheme, at least one light emitting element having the highest temperature sensitivity of all light emitting elements is driven more times than another one.
