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.

A design professional such as an interior designer, furniture sales associate or advertising designer running a browser program at a client computer (i) uses the world wide web to connect to a graphics server computer, and (ii) interactively selects or specifies furnishings or other objects from this server computer and previews the scene and communicates with the server, so as to (iii) receive and display to his or her client a high-fidelity high-quality virtual-reality perspective-view photorealistic image of furnishings or other objects displayed in, most commonly, a virtual representation of an actual room of a client's home or an advertisement scene. The photorealistic images, optionally provided to bona fide design professionals and their clients for free, but typically paid for by the product's manufacturer, promote the sale to the client of goods which are normally obtained through the graphics service provider's customer's distributor, profiting both the service provider and the design professional. Models, textures and maps of existing objects are built as necessary from object views or actual objects. Full custom objects, including furniture and other products 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 furniture, to view a virtual but photorealistic, image of a selected product located within a customer-selected scene, such as the prospective customer's own home, to allow in-context visualization.

A down sampler 13 down samples a digital signal in the sampling frequency thereof from 96 kHz to 48 kHz on a frame-by-frame basis. The converted signal is compression encoded and output as a main code Im. An up sampler 16 converts a partial signal corresponding to the main code Im to a signal having the original sampling frequency 96 kHz, for example. An error signal between the up sampled signal and an input digital signal is generated. An array converting and encoding unit 18 array converts bits of sample chains of the error signal, thereby outputting an error code Pe. On a decoding side, a high fidelity reproduced signal is obtained based on the main code Im and the error code Pe, or a reproduced signal is obtained based on the main code Im only.

A system comprises a rotary apparatus, a control law and a processor. The rotary apparatus comprises a rotor and a housing forming a gas path therebetween, and the control law controls flow along the gas path. The processor comprises an output module, a plurality of temperature modules, a thermodynamic module, a comparator and an estimator. The output module generates an output signal as a function of a plurality of rotor and housing temperatures defined along the gas path, and the temperature modules determine time derivatives of the rotor and housing temperatures. The thermodynamic module models boundary conditions for the gas path, and the comparator determines errors in the boundary conditions. The estimator estimates the rotor and housing temperatures based on the time derivatives, such that the errors are minimized and the flow is controlled.

Various computer-implemented methods are provided. One method for generating a process for inspecting reticle layout data includes identifying a first region in the reticle layout data. A printability of the first region is more sensitive to changes in process parameters than a printability of a second region in the reticle layout data. The method also includes assigning one or more inspection parameters to the first region and the second region such that the first region will be inspected during the process with a higher sensitivity than the second region. Another method includes inspecting the first region with a higher sensitivity than the second region. An additional method includes simulating how the reticle layout data will print. Simulation of the first and second regions is performed with one or more different simulation parameters such that the first region is simulated with a higher fidelity than the second region.

A method for controlling a graphical user interface (GUI) for a touchscreen-enabled computer systems provides a variety of software methods (tools) provide for high-fidelity control of the user interface. The TrackScreen tool provides finger-friendly mouse functions such as scrolling, dragging and clicking. The Magnifier application continuously captures the current screen image, and displays a magnified subset of it. Selecting within this magnified area with a pointing device (mouse, touchscreen, digitizer, etc) causes the application to simulate the action on the portion of the screen corresponding to the point in the magnified image that was selected. A KeyBoard application, a keyboard is rendered on screen, with sufficient size that the individual keys are easily selectable with an unaided finger. The Common Tasks Tool or CTT) allows common keyboard shortcuts, mouse events, and other user interface events to be specified in a configuration file and represented on screen as a large, easy-to-click button. The Touchscreen Task Switcher is invoked using any interface (software or hardware) element, and visually takes up the entire screen. The Touchscreen Snapshot utility ties in with an external camera with a physical button on it. The Window Template Manager (WTM), is used to specify, and then instantiate, the position and sizes of multiple windows for use with a touchscreen display. The Touch Portal is a full-screen application with a set of customizable buttons representing applications and other tools.

The present invention provides a method for identifying one or more low abundance sequences differing by one or more single-base changes, insertions, or deletions, from a high abundance sequence in a plurality of target nucleotide sequences. The high abundance wild-type sequence is selectively removed using high fidelity polymerase chain reaction analog conversion, facilitated by optimal buffer conditions, to create a restriction endonuclease site in the high abundance wild-type gene, but not in the low abundance mutant gene. This allows for digestion of the high abundance DNA. Subsequently the low abundant mutant DNA is amplified and detected by the ligase detection reaction assay. The present invention also relates to a kit for carrying out this procedure.

The present invention is related to implantable cardiac devices such as pacemakers and defibrillators that deliver cardiac resynchronization therapy (CRT), and to a method of optimizing acquisition of impedance signals between electrodes present on implanted lead systems. This system then automatically determines which electrodes or electrode combinations acquire impedance waveforms that have the best signal to noise ratio (highest fidelity) and characterize data most representative of dysynchronous electromechanical events. Using closed loop algorithms which provide electrograms and a variety of impedance data reflective of the patient's clinical status, the system autonomously modifies interval timing within the CRT device.

DTS Interactive provides low cost fully interactive immersive digital surround sound environment suitable for 3D gaming and other high fidelity audio applications, which can be configured to maintain compatibility with the existing infrastructure of Digital Surround Sound decoders. The component audio is stored and mixed in a compressed and simplified format that reduces memory requirements and processor utilization and increases the number of components that can be mixed without degrading audio quality. Techniques are also provided for “looping” compressed audio, which is an important and standard feature in gaming applications that manipulate PCM audio. 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 insert earphone is provided in which a piece of foam material is used to resiliently mount a receiver within a chamber portion of a one-piece plastic housing member. The receiver has an output port extending through a central aperture of the piece of foam material and into one end of a passage defined by a tubular portion of the housing member with a damper being disposed in the other end of the passage. The tubular portion is inserted into an ear tip or other coupling device and has an enlarged diameter end section to achieve a locking action. Two such insert earphones may be coupled through cables to a junction unit and filters are provided for enhancing the drive of the earphones at high frequencies, the filters being preferably mounted in the junction unit.

The invention is based on a highly efficient protocol for the delivery of high-quality multimedia communication services, such as video multicasting, video on demand, real-time interactive video telephony, and high-fidelity audio conferencing over a packet-switched network. The invention can be expressed in a variety of ways, including methods, systems, and data structures. One aspect of the invention involves a method in which a packet (10) of multimedia data is forwarded through a plurality of logical links in a packet-switched network using a datagram address contained in the packet (i.e., datagram address-based routing). Address information in partial address subfields of the datagram address self-directs the packet through a plurality of top-down logical links (70). (The plurality of top-down logical links are a subset of the plurality of logical links.) The packet remains unchanged as it is transferred along multiple links in the plurality of logical links.

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. This causes the beam pattern to be laid down in precisely the same way on each scan cycle, eliminating the need to record the orientations of the wedges accurately on every laser fire, thereby reducing ancillary data storage or transmission requirements by two to three orders of magnitude and greatly simplifying data preprocessing and analysis. The described system also uses a holographic element to split the laser beam into an array that is then scanned in an arbitrary pattern. This provides more uniform signal strength to the various imaging detector channels and reduces the level of optical crosstalk between channels, resulting in a higher fidelity three-dimensional image.

Ligase detection reaction is utilized to distinguish minority template in the presence of an excess of normal template with a thermostable ligase. This process can be carried out with a mutant ligase, thermostable ligase, or a modified oligonucleotide probe. This procedure is particularly useful for the detection of cancer-associated mutations. It has the advantage of providing a quantitative measure of the amount or ratio of minority template.
