Abstract: A robotic coordinate measurement machine (CMM) having a contact direction sensitive (CDS) probe is usable to detect internal dimensions for an object of interest. A robot arm may contact a surface with the CDS probe which may then detect a magnitude and direction of the resulting reaction force. The robotic CMM may monitor the magnitude and/or direction of the reaction force while the CDS probe is being slide across a surface to determine dimensions for the surface. Changes in the reaction force sensed by the CDS probe may be used to identify contact with other surfaces of contours in the surface the CDS probe is being slid across. A path of the CDS probe may be altered based on the contact with other surfaces or the contours.

Abstract: Techniques for context-based queryless presentation of items are described. Without receiving an explicit query, an inferred query is determined based on a first set of context signals associated with a triggering event.

One or more results items identifying the one or more matching items are caused to display. Result items may be displayed in association with an explanation that identifies context values used to select an item or one or more attributes of the item that are relevant to a user or the inferred query.

Abstract: Hybrid image projection systems and methods can superimpose image components of an input image. An input image can be divided into smaller regions and at least one parameter of each region can be determined. The input image can be decomposed based on the parameter of each region into multiple, less correlated, orthogonal or quasi-orthogonal image components. Each projector can display respective image components so that the images projected may be optically superimposed on a screen. The superposition of orthogonal or quasi-orthogonal image components can result in superposition of images in an existing multi-projector image systems being more insensitive to inter-projector image misalignment. Superimposing orthogonal or quasi-orthogonal images can be used to avoid visible image degradation, and provide more robust image quality in a multiple projector system implementation.
