Abstract: A position tracking system includes an infrared-sensitive device, such as an infrared camera that generates signals in response to detected infrared light in a field of view of the infrared-sensitive device. A processor is responsive to the signals generated by the infrared-sensitive device for determining a position of the detected infrared light. The processor also generates tilt and pan signals based on the position of the detected infrared light. A tilt and pan mechanism moves a visible-light video camera in response to the tilt and pan signals from the processor. The active infrared light-emitting device includes a loop having at least two infrared light-emitting elements disposed along the loop, on opposite sides of the loop. A control box is disposed in the loop and is in electrical communication with the infrared light-emitting elements.

Abstract: A document editing environment is provided that varies based on the type of user. One of a plurality of different types of security levels are assigned to different users who edit documents. A document editing environment is defined for a plurality of different types of documents based at least upon the security level assigned to a user who edits the document. The defined document editing environment is then provided to the user for use in editing a document.

Abstract: An automated method is provided for viewing production data for a print job. The production data includes an electronic document defined by a page description language (PDL). The electronic document is stored in a PDL image file and has predefined physical dimensions and a predetermined area in which the electronic document must fit in a layout of a physical printed document. In the method, a still image proxy is created of the PDL image file. A static template is created that defines the predetermined area. The physical dimensions of the template are dynamically determined based on the area in which the electronic document must fit in the layout of the physical printed document. The physical dimensions of an image display of the still image proxy are dynamically determined based on the relative size of the predefined physical dimensions of the PDL image file to the predetermined area in which the electronic document must fit.

Abstract: A process is provided to prepare production data for a print job. The production data includes an electronic document defined by a page description language (PDL). The electronic document is stored in a PDL image file, such as a Postscript file, a PDF file, or the like. A still image proxy, which may be a JPEG file, a GIF file, a PNG file, or the like, is created of the PDL image file. An image display of the still image proxy is electronically manipulated. In addition, production specifications may be appended to the image display of the still image proxy. Information about the manipulations and production specifications are recorded and subsequently used to revise the PDL image file so as to match the PDL image file to the manipulations made to the image display of the still image proxy and to match the production specifications appended to the image display of the still image proxy.
