Abstract: The present invention describes an image display apparatus for directing an image towards an observer. The apparatus comprises a source of image point rays; a collimating device configured to collimate image point rays to produce collimated image rays; and, a prism sheet configured to receive the collimated image rays. The prism sheet comprises an array of micro-prisms, each micro-prism having two reflective facets arranged such that each collimated image ray is reflected off one facet and then an adjacent facet. Reflection from the second facet reorients the collimated image rays towards an image observation zone. The collimated image rays from an upper portion of the prism sheet converge with collimated image rays from a lower portion of the prism sheet within the image observation zone. The present invention also describes a method for directing an image towards an observer.

Abstract: Coordinate measuring machines typically include a jogbox that allows an operator to control movements of a probe with a joystick and dedicated buttons. By facilitating advanced interaction between the jogbox and the dimensional metrology application, the jogbox may be used to control most or all of the functional aspects of the dimensional metrology application, including, in some instances, control of the coordinate measuring machine. The jogbox may include an adaptability of communications protocol such that it may interact with any one of a number of types or brands of coordinate measuring machines. A dynamic and flexible display and/or user input system may be employed to facilitate the use of a single jogbox with different systems. Further, the inherent flexibility of various jogbox embodiments disclosed herein may allow different categories of users to select and/or customize a jogbox interface.

Abstract: In a graphical desktop environment displaying desktop components, a control is provided to track the position of a pointer on a screen, and when the pointer enters relevant regions with respect to a desktop component, a thin or thick border in displayed around the desktop component to enable a user to resize the desktop component, and/or a caption bar is displayed along an edge of the component to enable a user to move the desktop component on the desktop. The caption bar may additionally be provided with menu and close buttons, to enable the user to bring up a menu of properties and/or actions for the desktop component, and close the desktop component, respectively. When the pointer is outside any region relevant to a desktop component, no borders or caption bars are displayed, thereby resulting in a visually less cluttered appearance.
