A system and process for broadcast and communication with bi-level or sketch video at extremely low bandwidths is described. Essentially, bi-level and sketch video presents the outlines of the objects in a scene being depicted. Bi-level and sketch video provides a clearer shape, smoother motion, shorter initial latency and cheaper computational cost than do conventional DCT-based video compression methods. This is accomplished by converting each color or gray-scale image frame to bi-level or sketch image frame using adaptive thresholding method, compressing bi-level or sketch image frames into bi-level or sketch video using adaptive context-based arithmetic coding method. Bi-level or sketch video is particularly suitable to such small devices as Pocket PCs and mobile phones that possess small display screen, low bandwidth connection, and light computational power.

A method and system for selectively fully displaying additional content in a browser window, without requiring scrolling in more than one direction, based on an available display area. For example, additional advertising content is thus selectively displayed in an otherwise unused area of the browsing window to the right of a primary content of a Web page. The size of the available display area is automatically detected, and a determination is automatically made as to whether the additional content and primary content can both be fully displayed in the available display area under the scrolling constraint. If so, both the additional content and the primary content are displayed. Otherwise, only the primary content is displayed. The additional content is downloaded only when it can thus be included within the display area. If the browser window is resized so that the additional content no longer fits without scrolling in more than one direction, the additional content is removed from the display, but is preferably retained in local storage for redisplay if the available display area is subsequently increased sufficiently. The type (and version) of browser program used is detected so that the appropriate instructions will be provided to the client device to selectively display additional content in this manner. For smaller client device displays, such as, on those on pocket PCs, the content provided by a server is selectively determined in a prioritized manner, as a function of the available display area.

Generation, coding and transmission of an effective video form, scalable portrait video. As an expansion to bi-level video, portrait video is composed of more gray levels, and therefore possesses higher visual quality while it maintains a low bit rate and low computational costs. Portrait video is a scalable video in that each video with a higher level always contains all the information of the video with a lower level. The bandwidths of 2–4 level portrait videos fit into the bandwidth range of 20–40 Kbps that GPRS and CDMA 1X can stably provide. Therefore, portrait video is very promising for video broadcast and communication on 2.5 G wireless networks. With portrait video technology, this system and method is the first to enable two-way video conferencing on Pocket PCs and Handheld PCs.

A method and system for detecting the presence of subterranean termites, involving use of a thermal imaging camera to scan the structure before installation of an acoustic sensor in order to quickly locate potential areas of subterranean termite infestation, and an acoustic sensor in the form of an accelerometer or the disclosed innovative acoustic sensors having a bandwidth of at least 100 Hz to 15 kHz to detect noises made by the subterranean termites. Information collected by the acoustic sensor may be transmitted to a portable mini-computer (pocket PC) for confirmation and to a central operations center for inclusion in a comprehensive database of termite data and information. A method and system for detecting the presence of dry-wood termites concealed in a structure, involving use of a heat source to warm up the wooden structure of interest and then using a thermal imaging camera to scan the structure for suspicious dry-wood infestation, followed by the use of an acoustic sensor and pattern recognition software to more precisely and accurately locate potential area of dry-wood termite infestation. Additionally, structural damage can be evaluated by the methods discussed herein, including live trees. Additionally, the method can be used to manipulate termite infestation behavior.

A GPS tuner provides high precision measurement, mapping, and Geocaching tools for a pocket PC and other mobile computing devices. The tuner accepts waypoints defining a desired route for navigation by a user, including land, water, and air routes. Waypoints comprise latitude, longitude, and altitude of a geographical coordinate; user-assigned names; a type of geographic coordinate and coordinate description; photos; and associated sounds. Waypoints are inputted by a user keying in way point data; by copying waypoints from another stored route; internet downloading from a Geocaching file; or importing from a GPX file. Waypoints are also established from a free-form hand-drawn route on a touch screen, which display a world-wide digital elevation model, and upon which a user scanned map is overlaid through a calibration process. Navigation functions are selectable from a touch screen display of a self-adapting, ergonomically configured, array of icons.

A mapping application relies on a modified affine transformation algorithm to provide near real-time navigation of imagery, track-up capability and integration of segment and picture data. The affine transformation is modified to map a “world space” comprised of a plurality of pixel maps onto a view port. The pixel data for the maps is preferably stored in vertical strips of memory to reduce the likelihood of cache misses. The mapping application is most useful for rendering pixel imagery on a platform with limited processing power, limited memory and small display sizes, e.g., “hand held devices” such as a GPS handset, or Pocket PC.

A portable communicator for operating a field device. The portable communicator is configured to communicate with the field device to configure and / or analyze performance of a field device in an efficient manner. In some embodiments, the portable communicator includes an intuitive user interface that allows the user to perform a relatively limited set of preconfigured procedures on a field device. The portable communicator may communicate with the field device via a wire and / or wirelessly. In one embodiment, the portable communicator is a Bluetooth-enabled smartphone, a PDA, a pocket PC, or any Bluetooth-enabled generic mobile communication device. The portable communicator may communicate with the field device via a wireless communication unit (e.g., Bluetooth modem) coupled to the field device. In a process plant environment, in which the field device is coupled to a controller, the portable communicator may communicate with the field device without communicating with the controller.
