  • Patent number: 11947251
    Abstract: An illumination system provides an illumination beam and includes a red light source, a green light source, a blue light source, a first supplementary light source, a first X-shaped light-splitting assembly, a first light-splitting element, and a light-uniforming element. The red light source provides a red beam. The green light source provides a green beam. The blue light source provides a blue beam. The first supplementary light source provides a first supplementary beam. The first X-shaped light-splitting assembly guides the first supplementary beam and the blue beam to the first light-splitting element. The first light-splitting element guides the red beam, the green beam, the blue beam, and the first supplementary beam to the light-uniforming element. The first supplementary beam is a red supplementary beam or a blue supplementary beam, and the illumination system includes at least five light-emitting elements. A projection apparatus including the above illumination system is also provided.

  • Patent number: 11914277
    Abstract: An illumination system for providing an illumination beam includes red, blue, and green light source modules, a first light combining element, and a light uniforming element. The red light source module includes a first red light emitting element emitting first red light and a second red light emitting element emitting second red light. A peak wavelength of the second red light is greater than a peak wavelength of the first red light. The blue light source module includes a first blue light emitting element emitting first blue light and a second blue light emitting element emitting second blue light. A peak wavelength of the second blue light is less than a peak wavelength of the first blue light. The green light source module generates green light. The first light combining element guides these lights into the light uniforming element, so that the illumination system outputs the illumination beam.

  • Patent number: 11917340
    Abstract: A projection device, including an illumination system, a control element, a driving element, a light valve, and a projection lens, is provided. The illumination system includes multiple light sources for providing multiple light beams to be combined into an illumination light beam. The driving element respectively drives the light sources in a first mode or a second mode, so that the light beams have respective luminous brightness, and the driving element is switched from the first mode to the second mode according to a first signal. The control element provides the first signal to the driving element according to an optical state or a time state of the projection device. The light valve is adapted to convert the illumination light beam into an image light beam. The projection lens is adapted to project the image light beam out of the projection device.

  • Patent number: 8057840
    Abstract: A food product comprises an oligosaccharide composition that is digestion resistant or slowly digestible. The oligosaccharide composition can be produced by a process that comprises producing an aqueous composition that comprises at least one oligosaccharide and at least one monosaccharide by saccharification of starch, membrane filtering the aqueous composition to form a monosaccharide-rich stream and an oligosaccharide-rich stream, and recovering the oligosaccharide-rich stream. Alternatively, the oligosaccharide composition can be produced by a process that comprises heating an aqueous feed composition that comprises at least one monosaccharide or linear saccharide oligomer, and that has a solids concentration of at least about 70% by weight, to a temperature of at least about 40° C.

  • Publication number: 20100047432
    Abstract: A process for preparing saccharide oligomers uses an aqueous feed composition that comprises at least one monosaccharide or linear saccharide oligomer, and has a solids concentration of at least about 70% by weight. The feed composition is heated to a temperature of at least about 40° C., and is contacted with at least one catalyst that accelerates the rate of cleavage or formation of glucosyl bonds, such as enzyme or acid, for a time sufficient to cause formation of non-linear saccharide oligomers. A product composition is produced that contains a higher concentration of non-linear saccharide oligomers than linear saccharide oligomers.
