An Integrated Routing/Mapping Information System (IRMIS) links desktop personal computer cartographic applications to one or more handheld organizer, personal digital assistant (PDA) or "palmtop" devices. Such devices may be optionally equipped with, or connected to, portable Global Positioning System (GPS) or equivalent position sensing device. Desktop application facilitates user selection of areas, starts, stops, destinations, maps and/or point and/or route information. It optionally includes supplemental online information, preferably for transfer to the PDA or equivalent device. Users' options include route information, area, and route maps. Maps and related route information are configured with differential detail and levels of magnitude. Used in the field, in conjunction with GPS receiver, the PDA device is configured to display directions, text and map formats, the user's current position, heading, speed, elevation, and so forth. Audible signals identifying the next turn along the user's planned route are also provided. The user can pan across maps and zoom between two or more map scales, levels of detail, or magnitudes. The IRMIS also provides for "automatic zooming," e.g., to show greater detail or closer detail as the user approaches a destination, or to larger scale and lower resolution to show the user's overall planned route between points of interest. The IRMIS also enables the user to mark or record specific locations and/or log actual travel routes, using GPS position information. These annotated location marks and/or "breadcrumb" or GPS log data can be saved, uploaded, displayed, or otherwise processed on the user's desktop geographic information or cartographic system. The IRMIS application and data may be distributed online and/or in tangible media in limited and advanced manipulation formats.

A portable communication device with multi-touch input detects one or more multi-touch contacts and motions and performs one or more operations on an object based on the one or more multi-touch contacts and/or motions. The object has a resolution that is less than a pre-determined threshold when the operation is performed on the object, and the object has a resolution that is greater than the pre-determined threshold at other times.

Carrier Interferometry (CI) provides wideband transmission protocols with frequency-band selectivity to improve interference rejection, reduce multipath fading, and enable operation across non-continuous frequency bands. Direct-sequence protocols, such as DS-CDMA, are provided with CI to greatly improve performance and reduce transceiver complexity. CI introduces families of orthogonal polyphase codes that can be used for channel coding, spreading, and/or multiple access. Unlike conventional DS-CDMA, CI coding is not necessary for energy spreading because a set of CI carriers has an inherently wide aggregate bandwidth. Instead, CI codes are used for channelization, energy smoothing in the frequency domain, and interference suppression. CI-based ultra-wideband protocols are implemented via frequency-domain processing to reduce synchronization problems, transceiver complexity, and poor multipath performance of conventional ultra-wideband systems. CI allows wideband protocols to be implemented with space-frequency processing and other array-processing techniques to provide either or both diversity combining and sub-space processing. CI also enables spatial processing without antenna arrays. Even the bandwidth efficiency of multicarrier protocols is greatly enhanced with CI. CI-based wavelets avoid time and frequency resolution trade-offs associated with conventional wavelet processing. CI-based Fourier transforms eliminate all multiplications, which greatly simplifies multi-frequency processing. The quantum-wave principles of CI improve all types of baseband and radio processing.

An apparatus for immersion optical lithography having a lens capable of relative movement in synchrony with a horizontal motion of a semiconductor wafer in a liquid environment where the synchronous motion of the lens apparatus and semiconductor wafer advantageously reduces the turbulence and air bubbles associated with a liquid environment. The relative motions of the lens and semiconductor wafer are substantially the same as the scanning process occurs resulting in optimal image resolution with minimal air bubbles, turbulence, and disruption of the liquid environment.

A method of producing a digital image with improved resolution during digital zooming, including simultaneously capturing a first low resolution digital image of a scene and a second higher resolution digital image of a portion of substantially the same scene. A composite image is then formed by combining the first low-resolution digital image and a corresponding portion of the high resolution digital image. Digital zooming of the composite image produces a zoomed image with high resolution throughout the zoom range and improved image quality.

An integrated endoscopic image acquisition and therapeutic delivery system for use in minimally invasive medical procedures (MIMPs). The system uses directed and scanned optical illumination provided by a scanning optical fiber or light waveguide that is driven by a piezoelectric or other electromechanical actuator included at a distal end of an integrated imaging and diagnostic/therapeutic instrument. The directed illumination provides high resolution imaging, at a wide field of view (FOV), and in full color that matches or excels the images produced by conventional flexible endoscopes. When using scanned optical illumination, the size and number of the photon detectors do not limit the resolution and number of pixels of the resulting image. Additional features include enhancement of topographical features, stereoscopic viewing, and accurate measurement of feature sizes of a region of interest in a patient's body that facilitate providing diagnosis, monitoring, and/or therapy with the instrument.

A liquid-filled balloon may be positioned between a workpiece, such as a semiconductor structure covered with a photoresist, and a lithography light source. The balloon includes a thin membrane that exhibits good optical and physical properties. Liquid contained in the balloon also exhibits good optical properties, including a refractive index higher than that of air. Light from the lithography light source passes through a mask, through a top layer of the balloon membrane, through the contained liquid, through a bottom layer of the balloon membrane, and onto the workpiece where it alters portions of the photoresist. As the liquid has a low absorption and a higher refractive index than air, the liquid-filled balloon system enhances resolution. Thus, the balloon provides optical benefits of liquid immersion without the complications of maintaining a liquid between (and in contact with) a lithographic light source mechanism and workpiece.

Different sized features in the array and in the periphery of an integrated circuit are patterned on a substrate in a single step. In particular, a mixed pattern, combining two separately formed patterns, is formed on a single mask layer and then transferred to the underlying substrate. The first of the separately formed patterns is formed by pitch multiplication and the second of the separately formed patterns is formed by conventional photolithography. The first of the separately formed patterns includes lines that are below the resolution of the photolithographic process used to form the second of the separately formed patterns. These lines are made by forming a pattern on photoresist and then etching that pattern into an amorphous carbon layer. Sidewall pacers having widths less than the widths of the un-etched parts of the amorphous carbon are formed on the sidewalls of the amorphous carbon. The amorphous carbon is then removed, leaving behind the sidewall spacers as a mask pattern. Thus, the spacers form a mask having feature sizes less than the resolution of the photolithography process used to form the pattern on the photoresist. A protective material is deposited around the spacers. The spacers are further protected using a hard mask and then photoresist is formed and patterned over the hard mask. The photoresist pattern is transferred through the hard mask to the protective material. The pattern made out by the spacers and the temporary material is then transferred to an underlying amorphous carbon hard mask layer. The pattern, having features of difference sizes, is then transferred to the underlying substrate.

In response to a query for information in a geographic region or at a location, ranked ads may be plotted on, or in association with, a map (e.g., as a list beside the map), satellite photo, or any other form of visual representation of geographic information (referred to generally as “maps”). Sponsored ads might be shown in a dedicated place and/or might be elevated above other non-sponsored search results (e.g., Yellow Page listings). The number of ads shown in the list and/or plotted on the map could vary as a function of the resolution of the map or geographic image. The ads could be ranked or scored, and attributes or features of various ads may be a function of such a score or ranking. The plots on the map might be selectable to provide a pop-up with further information and possibly sponsored information (such as images, further ads, etc).

An image processing apparatus for tracking faces in an image stream iteratively receives an acquired image from the image stream potentially including one or more face regions. The acquired image is sub-sampled at a specified resolution to provide a sub-sampled image. An integral image is then calculated for a least a portion of the sub-sampled image. Fixed size face detection is applied to at least a portion of the integral image to provide a set of candidate face regions. Responsive to the set of candidate face regions produced and any previously detected candidate face regions, the resolution is adjusted for sub-sampling a subsequent acquired image.

Controls for an optical scanner, such as a single fiber scanning endoscope (SFSE) that includes a resonating optical fiber and a single photodetector to produce large field of view, high-resolution images. A nonlinear control scheme with feedback linearization is employed in one type of control to accurately produce a desired scan. Open loop and closed loops controllers are applied to the nonlinear optical scanner of the SFSE. A closed loop control (no model) uses either phase locked loop and PID controllers, or a dual-phase lock-in amplifier and two PIDs for each axis controlled. Other forms of the control that employ a model use a frequency space tracking control, an error space tracking control, feedback linearizing controls, an adaptive control, and a sliding mode control.

High-resolution, scalable multi-touch sensing display systems and processes based on frustrated total internal reflection employ an optical waveguide that receives light, such as infrared light, that undergoes total internal reflection and an imaging sensor that detects light that escapes the optical waveguide caused by frustration of the total internal reflection due to contact by a user. The optical waveguide may be fitted with a compliant surface overlay to greatly improve sensing performance, minimize the affect of contaminants on and damage to the contact surface, to generally extend system life and to provide other benefits. The systems and processes provide true multi-touch (multi-input) and high-spatial and temporal resolution capability due to the continuous imaging of the frustrated total internal reflection that escapes the entire optical waveguide. Among other features and benefits, the systems and processes are scalable to large installations and are well suited for use with rear-projection and other display devices.

The electronic device includes at least a first panel having a first display surface and a second panel having a second display surface. An effective screen size or a screen resolution corresponding to a viewing area that includes the first display surface and the second display surface is modified in response to the hardware configuration change. The method also includes sending at least one parameter associated with or based on the modified effective screen size or the modified screen resolution to a server.

A system and method for seamlessly combining client-only rendering techniques with server-only rendering techniques. The approach uses a composite stream containing three distinct streams. Two of the streams are synchronized and transmit camera definition, video of server-rendered objects, and a time dependent depth map for the server-rendered object. The third stream is available to send geometry from the server to the client, for local rendering if appropriate. The invention can satisfy a number of viewing applications. For example, initially the most relevant geometry can stream to the client for high quality local rendering while the server delivers renderings of less relevant geometry at lower resolutions. After the most relevant geometry has been delivered to the client, the less important geometry can be optionally streamed to the client to increase the fidelity of the entire scene. In the limit, all of the geometry is transferred to the client and the situation corresponds to client-only rendering system where local graphics hardware is used to improve fidelity and reduce bandwidth. Alternatively, if a client does not have local three-dimensional graphics capability then the server can transmit only the video of the server-rendered object and drop the other two streams. In either case, the approach also permits for a progressive improvement in the server-rendered image whenever the scene becomes static. Bandwidth that was previously used to represent changing images is allocated to improving the fidelity of the server-rendered image whenever the scene becomes static.
