Abstract: Internal structures, features and properties in volumetric datasets are mostly obscured and hidden. In order to reveal and explore them, appropriate tools are required to remove and carve the occluding materials, isolate and extract different regions of interest. A framework of interactive tools are provided for real-time volume manipulation, sculpting, segmentation, and visualization. A GPU-based point radiation technique provides as a fundamental building block to create a collection of high-quality volume manipulation tools for direct drilling, lasering, peeling, cutting, and/or pasting. Interactive parallel region growing segmentation is described that allows multiple seeds planting by direct sketching on different volumetric regions with segmentation results dynamically modified during the process. The point radiation technique creates high-quality real-time feedback of the segmented regions during the seeded growing process.

Abstract: A non-aqueous liquid un-molding composition is provided for use in the baking industry and an application method for this composition. The composition of the present application includes oil, wax and an emulsifying agent but no water. As a result the dough excess in the mold edges do not burn resulting in the infiltration of dirt into the bakery product that can cause contamination of the bakery product. A method of applying the compound is provided by sprays, application pistols, as well as of modular pulverization systems that facilitate the performance of automatic pulverization pistols, pulverizing the desired surface in a uniform and accurate way.

Abstract: A video compression encoder which does not require a video frame buffer is disclosed. Without a frame buffer, incoming pixels can not be compared to pixels previously sent to the decoder. Instead, the disclosed encoder only stores check values for groups of pixels sent. If a group's check value has not changed, the encoder sends a command to the decoder not to change that pixel group. Also, without a frame buffer, an incoming video frame can not be captured and later sent to the decoder as network throughput permits. Instead, if throughput is insufficient to send an encoded group of pixels, the encoder leaves the check value for that group unchanged and sends a command instructing the decoder not to change those pixels. This defers updating that group until the next screen update is sent to the decoder. Grouping of pixels can be done in any fashion, for example; a group can be a single video line, a portion of a line, multiple lines or screen rectangles containing portions of multiple lines.

Abstract: A method and system to consistently and automatically conditioning and delivering a solid-free liquid (filtrate) sample suitable for instrumental analysis is disclosed. A slurry, preferably a slurry produced by a sub-atmospheric pressure chlorate dioxide generating process, is fed through a filter to remove the solid phase and to provide the liquid phase on the downstream side of the filter, where the concentration of at least one dissolved component is determined.

Abstract: The present invention relates to a duplexer set up by two decoupling filters for high frequency transceivers of the temperature self-compensating type and implemented by means of a pair of mechanic bodies (2), each one of which including a plurality of resonance cavities (3). Inside of the cavity (3) of the superior body (2) of the duplexer, a corresponding adjustment disc (7) is lodged in a removable and coaxial way which is provided with a supporting stem (8) coming out of a passage hole (12) obtained on the summit of the cavity (3). The bodies (2) are bound between them, so that the cavities of one or the other turn out to be coaxially facing each other. The passage hole (12) of the filter according to the invention is threaded. Moreover at each filter at least one bush (9) is associated having one portion (11) engaged in the hole (12) and inside of which the stem (8) of the disc (7) is housed.

Abstract: An antenna duplexer including an elongated hollow body realized with two opposed half shells is disclosed. The duplexer also includes a first opening or antenna port and a second and a third opening, or ports of the transmitter and of the receiver. A filtering structure is provided including a plurality of metal inserts available to uncouple the transmitter from the receiver. The duplexer has at least an additional portion of waveguide structured in order to keep the wave “under the cut-off frequency”, interposed between at least second or third opening and the relative end wall of the elongated body. An additional portion of wave guide includes an additional metal insert, forming part of the above mentioned filtering structure, which determines an exponential attenuation of the signal, thus nullifying the negative effects deriving from the mechanical tolerance of the hollow body.

Abstract: In order to vary the timing of the ignition of an air/fuel mixture in a cylinder of an internal-combustion engine as a function of engine speed, a flip-flop is set by an engine-controlled switch at a predetermined point t.sub.0 in the cycle, in a position preceding by an angle .alpha..sub.0 the upper-dead-center position of an associated piston, to effect a rapid discharge and to start a slow recharge, at constant rate, of a capacitor C.sub.1 forming part of a time/voltage converter. The maximum voltage attained by this capacitor at the end of a cycle, as a measure of cycle length T, is registered in an ancillary capacitor C.sub.3 as another capacitor C.sub.2, forming part of a voltage/time converter, also begins charging at time t.sub.0 at a rate making the charges of capacitors C.sub.2 and C.sub.3 equal on or before the attainment of the UDC position. This equality is detected by a comparator which thereupon, at a time t.sub.0 +t.sub..gamma.
