Abstract: A gaze virtual object is displayed that is selectable based on attention directed to the gaze virtual object to perform an operation associated with a selectable virtual object. An indication of attention of a user is displayed. An enlarged view of a region of a user interface is displayed. A value of a slider element is adjusted based on attention of a user. A user interface element is moved at a respective rate based on attention of a user. Text is entered into a text entry field in response to speech inputs. A value for a value selection user interface object is updated based on attention of a user. Movement of a virtual object is facilitated based on direct touch interactions. A user input is facilitated for displaying a selection refinement user interface object. A visual indicator is displayed indicating progress toward selecting a virtual object when criteria are met.

Abstract: Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, translaminar lumbar fusion and lumbar facet fusion involving a curved implant structure.

Abstract: A method and apparatus is disclosed which comprises a portable treatment method and apparatus for treating sediment and other waste material. A preselected solid composition is added to the sediment as it is drawn through a system which mixes the sediment and composition thoroughly to produce a homogenous mixture, which is then in turn deposited in a storage device for eventual removal from the site.

Abstract: A fabric activator includes a webbing strip with a bracket secured thereto which operatively connects the fabric strip to the slider of the female fitting of a conventional canopy release system. The slider is moved back and forth responsive to a force or pull on the strip in one direction or another. The strip is normally held in a first, upper position (canopy release system locked) by a quick release fabric fastener. A second transverse strip is folded with the ends releasably secured together across the first strip to act as a protective cover.
