Abstract: A transparent holographic diffuser screen that diffracts the light beams of a digital light projector, which focuses a real image in the plane of the aforementioned transparent holographic diffuser screen, which redirects the light to an eyebox at a pre-determined viewing position generating as a set of diffracted diffused beams that can be seen from the eyebox as a flat in-plane image. The transparent holographic diffuser screen may be used to provide either a highest luminance or a largest eyebox. Potential applications include use for automotive applications, which may include applications for displaying videos, playing games, and video conference apps.

Abstract: A holographic substrate-guided wave-based see-through display can has a microdisplay, capable of emitting light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the light in the form of an image. The microdisplay directs its output to a holographic optical element, capable of accepting the image from the microdisplay, and capable of transmitting the light. The holographic optical element couples its output to an elongate substrate, capable of accepting the light from the holographic lens at a first location, and transmitting the light along a length of the substrate by total internal reflection to a second location, the elongate substrate being capable of transmitting the accepted light from the second location.

The substrate couples out what it receives to a transparent holographic optical element, capable of accepting the light transmitted from the substrate and transmitting it to a location outside of the holographic optical element as a viewable image.

The holographic lens couples its output to an elongate transparent substrate, capable of accepting the light in the form of an image from the holographic lens at a first location, and transmitting the light in the form of an image along a length of the substrate by total internal reflection to a second location spaced from the first location, the elongate substrate being capable of transmitting the accepted light in the form of an image at the second location.

Abstract: A method and system for determining document content based actions. A rule engine is provided with a document to be acted on, preferably in XML format. The rule engine is also provided with a set of rules and associated actions to be taken upon special conditions. The document is evaluated according to the rules and the document contents; each of the rules is parsed into a parse tree, the document is further evaluated, including, for the provided document, populating the parse tree with at least a portion of the document contents, to create a content-populated parse tree. The portion of the actions to be initiated is selected based on the content-populated parse tree. Actions could include, by way of example, security control or further routing of the document.

Abstract: Method for establishing a telecommunication connection wherein a calling party at a first telecommunication terminal station external to a private branch exchange (PBX) sets up a first connection to the PBX via a public telecommunication network and transmits information to the PBX which indicates, inter alia, a telephone number of a second telecommunication terminal station. In response, the PBX sets up a telecommunication connection between the first telecommunication terminal station and the second terminal station and, in addition, the PBX stores information relating to call charges resulting from the connection to the second terminal station.
