A design professional such as an interior designer running a browser program at a client computer (i) optionally causes a digital image of a room, or a room model, or room images to be transmitted across the world wide web to a graphics server computer, and (ii) interactively selects furnishings from this server computer, so as to (iii) receive and display to his or her client a high-fidelity high-quality virtual-reality perspective-view image of furnishings displayed in, most commonly, an actual room of a client's home. Opticians may, for example, (i) upload one or more images of a client's head, and (ii) select eyeglass frames and components, to (iii) display to a prospective customer eyeglasses upon the customer's own head. The realistic images, optionally provided to bona fide design professionals for free, promote the sale to the client of goods which are normally obtained through the graphics service provider, profiting both the service provider and the design professional. Models of existing objects are built as necessary from object views. Full custom objects, including furniture and eyeglasses not yet built, are readily presented in realistic virtual image.Also, a method of interactive advertising permits a prospective customer of a product, such as a vehicle, to view a virtual image of the selected product located within a customer-selected virtual scene, such as the prospective customer's own home driveway. Imaging for all purposes is supported by comprehensive and complete 2D to 3D image translation with precise object placement, scaling, angular rotation, coloration, shading and lighting so as to deliver flattering perspective images that, by selective lighting, arguably look better than actual photographs of real world objects within the real world.

A prefilter (5) for an audio system comprising a loudspeaker (1) in a room (2), which corrects both amplitude and phase errors due to the loudspeaker (1) by a linear phase correction filter response and corrects the amplitude response of the room (2) whilst introducing the minimum possible amount of extra phase distortion by employing a minimum phase correction filter stage. A test signal generator (8) generates a signal comprising a periodic frequency sweep with a greater phase repetition period than the frequency repetition period. A microphone (7) positioned at various points in the room (2) measures the audio signal processed by the room (2) and loudspeaker (1), and a coefficient calculator (6) (e.g. a digital signal processor device) derives the signal response of the room and thereby a requisite minimum phase correction to be cascaded with the linear phase correction already calculated for the loudspeaker (1). Filter (5) may comprise the same digital signal processor as the coefficient calculator (6). Applications in high fidelity audio reproduction, and in car stereo reproduction.

Media objects are transformed into active, connected objects via identifiers embedded into them or their containers. In the context of a user's playback experience, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server. The server, in turn, maps the identifier to an action, such as returning metadata, re-directing the request to one or more other servers, requesting information from another server to identify the media object, etc. The server may return a higher fidelity version of content from which the identifier was extracted. In some applications, the higher fidelity version may be substituted for the original media object and rendered to provide higher quality output. The linking process applies to broadcast objects as well as objects transmitted over networks in streaming and compressed file formats.

In addition, decoder sync is ensured by transmitting frames of “silence” whenever mixed audio is not present either due to processing latency or the gaming application.

An integrated circuit fabrication process as described herein employs a double photoresist exposure technique. After creation of a first pattern of photoresist features on a wafer, a second photoresist layer is formed over the first pattern of photoresist features. The second photoresist layer is subjected to a reflow step that softens and relaxes the second photoresist material. This reflow step causes the exposed surface of the second photoresist layer to become substantially planar. Thereafter, the second photoresist layer can be exposed and developed to create a second pattern of photoresist features on the wafer. The planar surface of the second photoresist layer, which results from the reflow step, facilitates the creation of accurate, precise, and “high fidelity” photoresist features from the second photoresist material.

A high fidelity distributed plant simulation technique includes a plurality of separate simulation modules that may be stored and executed separately in different drops or computing devices. The simulation modules communicate directly with one another to perform accurate simulation of a plant, without requiring a centralized coordinator to coordinate the operation of the simulation system. In particular, numerous simulation modules are created, with each simulation module including a model of an associated plant element and these simulation modules are stored in different drops of a computer network to perform distributed simulation of a plant or a portion of a plant. At least some of the simulation modules, when executing, perform mass flow balances taking into account process variables associated with adjacent simulation modules to thereby assure pressure, temperature and flow balancing (i.e., conservation of mass flow) through the entire simulation system. In a dynamic situation, a transient mass storage relay technique is used to account for transient changes in mass flow through any non-storage devices being simulated by the simulation modules. Moreover, adjacent simulation modules located in different drops communicate directly with one another using a background processing task, which simplifies communications between adjacent simulation modules without the need for a central coordinator.

An optical scanner system for contiguous three-dimensional topographic or volumetric imaging of a surface from an aircraft or spacecraft is disclosed. A servo controller synchronizes the rotation rates of a pair of wedge scanners with high precision to the multi-kilohertz laser fire rate producing an infinite variety of well-controlled scan patterns.
