Abstract: Colorless or colored coatings can be ink jetted onto a substrate using an aqueous particle-free inkjet ink composition that has a viscosity of less than 5 centipoises, and that includes a combination of an anionic polyether polyurethane and an anionic acrylic polymer or anionic styrene-acrylic polymer, in a total amount of less than or equal to 20 weight %. The composition can be colorless (free of colorants) or it can contain a suitable colorant to provide a color image. The composition also includes a defoamer that has a hydrophilic-lipophilic balance value of at least 3 and up to and including 5, and which is present in an amount of at least 0.15 weight % and up to and including 1 weight %. Such composition can be used in inkjet printing methods including recirculation apparatus and methods, and can be provided as part of an ink set.

Abstract: An aqueous organic pigment dispersion contains a green copper phthalocyanine pigment and an azo-coupled ?-ketoamide pigment. It also includes an organic pigment dispersant at 40 weight % to 100 weight %, based on the sum of the weights of the organic pigments. This aqueous organic pigment dispersion can be combined with a humectant to provide an aqueous green inkjet ink composition. The weight ratio of the green copper phthalocyanine pigment to the azo-coupled ?-ketoamide pigment is from 1:1 to 10:1. The median particle diameter of each of the green copper phthalocyanine pigment and the azo-coupled ?-ketoamide pigment is less than 85 nm. At least 95% of the total particles of each of the green copper phthalocyanine pigment and the azo-coupled ?-ketoamide pigment have a particle diameter of less than 150 nm. The aqueous green inkjet ink compositions can be used in various inkjet printing methods.

Abstract: Distortion due to transmission characteristics of a transmission medium is corrected by measuring leakage in a signal orthogonal to a received signal. The frequency response of an equalizer is adaptively adjusted until the measured leakage is at a local minimum.

Abstract: A method and system of providing a three dimensional spatial user interface (SUI) to a user of a computing device. The SUI may be manipulated in three dimensions and contains a plurality of portals. A portal may contain a sensory cue that provides a reminder as to the content of the portal. Upon selection of a portal, an application program associated with the cue in the portal is invoked. Portals may also contain further instances of the SUI of the present invention, thus providing hierarchical depth. In the preferred embodiment, the SUI is implemented as a sphere and may be viewed from an external or internal perspective.

Abstract: Hybrid fiber/coax networks employ the existing cable plant used for cable TV and transmit data signals in a frequency bandwidth above that which is used for cable TV. As this cable plant was deployed in a tree and branch topology, data transmissions may be susceptible to noise, variable transmission loss and frequency dispersion, particularly in the upstream direction. Further, due to the tree and branch topology, homes at the far end of the network experience much greater loss than do the homes that are near to the headend/ONU. The present system, which uses point-to-point data links between intelligent network elements located in the feeder/distribution network to provide reliable, secure, bi-directional broadband access. Digital signals are terminated at the intelligent network elements, switched and regenerated for transmission across additional upstream or downstream data links as needed to connect a home to a headend or router.
