Abstract: A highly advantageous domain name system and method are disclosed for receiving and replying to queries for information associated with at least one Internet connected domain in which replies to queries are based at least in part on the identity of the querying entity.

Abstract: A method, system, and apparatus are disclosed for producing enhanced three dimensional effects. The invention emulates physical processes of focusing wherein objects in the foreground and the background are in varying degrees out-of-focus and represented differently to each of a viewer's eyes. In particular, the invention divides out-of-focus light representations so that different partitions of such a division are viewed by a viewer's right eye as compared to what is viewed by the viewer's left eye, and so that the identical in-focus representation is viewed by both eyes. Thus, the invention interposes novel processing between a determination as to what to render in a synthetically produced three dimensional space and the actual rendering thereof, wherein the novel processing produces stereoscopic views from a two dimensional view by utilizing information about the relation of light sources in the three dimensional space to the in-focus plane in the space.

Abstract: A method for creating stereoscopic images wherein an image altering filter is interposed at the aperture stop of a relay lens system. The relay lens system forms an adapter between the ocular hole of an instrument and the oculars of an instrument. When a pair of such adapters are used in a binocular instrument, and when the adapters are correctly oriented, a 3D image is made available for viewing.

Abstract: A method and system for identifying predetermined attributes of information destined for multiple recipients (e.g., emails) and selecting (or sequencing) the information for transmission from a single queue based on those attributes. The emails can be organized so that they can be more efficiently transmitted to their recipients based on the individual attributes of the emails.

Abstract: The present invention is directed to optical systems and aperture valves for producing stereoscopic images and to digital irises. One embodiment of the invention provides an optical system that has two of two-dimensional, three-dimensional, and inverse three-dimensional modes. Another embodiment provides a light valve using a plurality of regions of differing optical transmissivities. Another embodiment provides an optical system using a leading and/or analyzing filter that encodes only a portion of the light encoded by an encoder positioned at the aperture stop or conjugate thereof. Another embodiment provides a digital iris which includes a plurality of independently controllable pixels. Each pixel, for example, can include an active optical material, such as a liquid crystal material, and electrical conductors to apply a voltage across the material. The pixel alternates between transmissive and occlusive states.

Abstract: The present invention is directed to various stereoscopic optical apparatuses. In one configuration, the apparatus uses a common optical encoder to interface with a number of different objectives. In one configuration, the apparatus uses an encoder that can be either removed from the optical path or reconfigured to produce a two-dimensional rather than a three-dimensional representation of an object. In one configuration, an optical encoder is provided that can provide filtration based on wavelength alone or based on both polarization and wavelength.

Abstract: A method and teaching for creating stereographic images with the use of a single lens is presented. A leading linear polarizing filter, a passive half-wave retarder, an electric switched quarter-wave retarder, and a trailing linear polarizing filter are then used in various combination to create: a 3D microscope, a 3D video adapter for microscopes, a general purpose 3D video lens, a 3D video adapter, and a 3D light-valve. A neutral density filter replaces those components to then create a 3D ocular and a 3D ocular adapter.

Abstract: Information common to multiple e-mail messages (called common content "chunks") is separated from the individual e-mail messages before transmission. The chunks are then transmitted separately from the individual e-mail message information, and reassembled into a complete e-mail message at the receiving site.

Abstract: A high volume e-mail "newspaper" delivery system contains, for each customer, a personal configuration file containing the information resources that the customer would like e-mailed to his desktop. The configuration file is highly customizable, allowing the end-user detailed control over the content, format, and timing of the delivered e-mails. The e-mail messages to be sent are hashed to multiple, parallel transmission queues based on their destination MX hosts. This arrangement of transmission queues significantly increases total e-mail output because multiple queues are simultaneously processing the e-mail transmissions. A unique job number is appended to each e-mail message as it is created. The job number is used by the system to identify and track the e-mail message through the system before it is transmitted, and if the message bounces, when it returns to the system.
