Abstract: In one example implementation, a computing device displays a first application window and second application window adjacent to each other in a multi-application viewing area. The computing device detects a gesture in either an upper gesture detection area or a lower gesture detection area and controls either the first application window or second application window based on the gesture.

Abstract: In a 3D printing method example, color is added to a part. A build material is applied, and is pre-heated to a temperature ranging from about 50 C to about 400 C. A black ink, including an infrared absorbing colorant, is selectively applied on at least a portion of the build material. A white ink, including a white colorant that is opaque in visible wavelengths and is transparent to infrared wavelengths, is selectively applied on the black ink. A colored ink, including a colorant having a color other than black or white, is selectively applied on the white ink. The build material and the applied inks are then exposed to infrared radiation. The black ink at least partially fuses the portion of the build material in contact therewith. At least some of the white colorant and the colorant are embedded in the at least partially fused portion at a surface thereof.

Abstract: Systems to accurately position an instrument includes an instrument with an interest point, an optical sensing system having a camera and a sensor coupled to a surface of the instrument, a motion detector, and a processor. The optical sensing system collects a set of optically-sensed positional data points. The motion detector collects a set of motion-sensed positional data points. The processor applies a correction function on the set of optically-sensed positional data points and on the set of motion-sensed positional data points to provide a set of corrected positional data points.

Abstract: In one example, a shroud to protect a group of printheads in a printhead assembly includes openings through which the printheads are exposed when the shroud is installed on the printhead assembly and an elongated protrusion along an exterior surface next to the openings to block print media from contacting the exposed part of the printheads during printing when the shroud is installed on the printhead assembly.

Abstract: An example method of rapid image registration includes recovering an affine transform of a quasi-periodic object based on peak locations of Discrete Fourier Transform (DFT) in a captured image. The example method also includes filtering a region of the captured image to match a filtered version of a reference image including the quasi periodic object. The example method also includes recovering translation parameters to reduce image differences between the reference image and the captured image for a subset of the image locations of the filtered image and outputting an approximate transform including translation.

Abstract: Ink supplies and methods to prepare an ink supply are disclosed. An example ink supply (106) for a printer (100) includes an ink chamber (108) to store ink (1308), and a machine readable storage medium (110) to store a priming parameter (202-226), the priming parameter (202-226) having a value to cause a printer (100) to configure a priming procedure of the printer (100).

Abstract: Embodiments of the present invention are directed to determining the spectral vector of electromagnetic radiation reflected from, transmitted through, or emitted from a sample using a set of n intensity measurements. In general, the spectral vector has a dimension k that is greater than the number of measured intensities n. However, in many cases, the physical and chemical constraints of a system, when properly identified and modeled, effectively reduce the number of unknowns, generally the k components of the spectral vector, to an extent that allows for the spectral vector to be characterized from a relatively small number n of measured intensities.
