Abstract: A computing system includes a touch display and a virtual keyboard visually presented by the touch display. The virtual keyboard includes one or more slider buttons, and each slider button includes a plurality of touch-selectable items. The computing system further includes a touch-detection module configured to recognize which of the plurality of touch-selectable items is being touched, and a visual-feedback module configured to visually indicate that a touch-selectable item is considered to be ready for selection responsive to that touch-selectable item being touched. The computing system also includes a selection module configured to input a touch-selectable item responsive to a touch lifting from that touch-selectable item while the visual-feedback module visually indicates that touch-selectable item is considered to be ready for selection.

Abstract: A computing system includes a touch display and a virtual keyboard visually presented by the touch display. The virtual keyboard includes one or more rows of staggered virtual-touch-input keys. The computing system further includes a touch-to-key assignment module configured to assign a touch directed to the virtual keyboard and recognized by the touch display to a virtual-touch-input key.

Abstract: A manipulator for a fiber optic cable assembly (FOCA) provides microradian accuracy in control of the direction of a beam emanating from the FOCA. Such manipulators can control FOCAs to control the incidence angles of beams at a beam combiner in a beam-combining unit. Accordingly, fewer additional optical elements are required for control of input paths in the beam-combining unit. The manipulator and the beam-combining unit are accurate enough for use in an interferometer that combines beams with different frequencies and polarizations. One such interferometer includes a Zeeman split laser providing a heterodyne beam. A beam splitter separates frequency components of the beams, and AOMs increase the frequency separation between the separated beams. The separated beams can be sent via optical fibers to the beam-combining unit, which combines the beams for use in interferometer optics.

Abstract: An optical mounting is described and which has two opposite faces, a reference axis which is generally perpendicular to the faces, at least one arcuate slot which joins the faces and which defines an interior part and an exterior part and means for moving the interior part relative to the exterior part. The slot has sufficient length and width so as to allow limited movement between the two parts. The interior part has an aperture located therein for receiving an optical component.
