In the example method, the first wireless telephone device terminal includes a first media decoder configured to decode a first media encoding format and the second wireless telephone device terminal includes a second media decoder configured to decode a second media encoding format. The example method also involves receiving a first media presentation via the first wireless telephone device terminal and a second media presentation via the second wireless telephone device terminal. The first media presentation is encoded using the first media encoding format and the second media presentation is encoded using the second media encoding format.

Abstract: A system and method for inspecting an object, the system and method comprising a source for generating a penetrating radiation beam for irradiating the object, the beam having, for each instant of time, an instantaneous energy spectrum of intensity, a shaper for modulating the generated beam, thereby creating a shaped beam, the shaper comprising at least a first section and a second section, the first section attenuating the intensity of a portion of the generated beam by a first attenuation factor and the second section attenuating the intensity of another portion of the generated beam by a second attenuation factor, and at least one detector for detecting the shaped beam after the shaped beam interacts with the object. The source may scan a beam across an object while the source and at least one detector are moving on a platform capable of highway travel or on an inspection module movable with respect to the object.

Abstract: A system and method for inspecting an object. The system has a source for generating a penetrating radiation beam for irradiating the object and at least one detector for detecting the beam after the beam interacts with the object. Furthermore, the system has an aperture interposed between the source and the object, the aperture characterized by a cross-sectional dimension, and the cross-sectional dimension capable of variation on a periodic basis during the course of inspecting the object such that high resolution is obtained for regions of the object characterized by lower opacity while penetration is achieved at lower spatial resolution for regions of more substantial opacity.

Abstract: Genome browsers are software tools for visualizing DNA sequence in the context of its annotation. Genome browsers are critical tools for assisting the analytical task of manually integrating annotations from various algorithms, none of which are 100% trusted. All genome browsers use some combination of stacking and banding annotations around a sequence. The spreadsheet is a vehicle for presenting stacked and banded annotation. Gadget is a new genome browser that uses a spreadsheet-like interface to organize annotation. Gadget's layout is useful and simple to implement using pre-existing software libraries.

Abstract: An inspection system for inspecting an enclosure and its contents using temporally gated sources of penetrating radiation. A first source produces an intermittent first beam having a duration of inactivity while a second sources produces a second beam, which may have an energy spectrum differing from that of the first beam, during the inactivity of the first beam. One detector generates a transmission signal based on penetrating radiation transmitted through the enclosure while a scatter detector generates a scatter signal based on penetrating radiation scattered by the contents of the enclosure. The scatter detector may be gated for non-detection during the pulsing of the transmission beam. A processor derives properties of the contents of the enclosure on the basis of the transmission signal and the scatter signal.

Abstract: A wheel lock assembly for an in-line skate includes an axle assembly for supporting a skate wheel and defining an enclosed cavity, and an actuator assembly comprising an actuator member disposed in the cavity movable by a control member disposed externally of the axle assembly. The lock assembly further includes a lock pad assembly comprising a lock pad adapted to engage an inside surface of the skate wheel mounted on the axle assembly, a support beam extending from the pad inwardly through a portion of the axle assembly and into the cavity, and a spring urging the lock pad and support inwardly to bias a free end of the support against the actuator member. Manipulation of the control member causes movement of the actuator member in the cavity, to cause movement of the support, to cause radial movement of the lock pad selectively into and out of engagement with the skate wheel inside surface.

Abstract: A radiant energy imaging apparatus for obtaining CT scans employs an X-ray unit operative to produce a pencil beam of X-ray radiant energy which is caused to scan in a horizontal plane through an angle, sufficiently great to embrace a cross section of a human body being examined, along a single, elongated, horizontally oriented detector forming a portion of the X-ray unit and located on the side of the body opposite to an X-ray source in the unit. A supporting structure, adapted to be rotated about a vertical axis, supports a human body in a vertical orientation; and when the system is scanning in the CT mode, the supporting structure rotates the human body smoothly and continuously about a vertical axis while the X-ray unit is held at a fixed position adjacent a horizontal section of interest of the human body.

Abstract: A CT scanner having a rotating X-ray source and a stationary circular array of 600 contiguous detectors includes a sliding shutter mechanism incorporated in the precollimator system that prevents detectors at the beginning and at the end of a scan from receiving radiation while progressively increasing and decreasing, respectively, the current to the X-ray tube.

Abstract: A fast, large aperture, electrically actuated shutter mechanism capable of ithstanding high power densities. The shutter's ability to withstand high power densities is achieved by making the shutter plate highly reflective on one side and providing cooling means on the opposite side.

Abstract: A cable handling mechanism for an X-ray tomographic scanner having a rotor assembly for making a scan of about two revolutions and then rewinding to an initial position includes two axially displaced drums. One drum is attached to the rotor housing and rotates with it; the other is fixed to the stationary structure. A pulley carrier between the two drums is rotatable about the same axis and carries large and small idler pulleys. At one extreme end position one or more individual cables inside a loose-fitting flexible tube are wound around the rotating drum for two turns, around the large idler pulley and in the opposite direction around the fixed drum for a single turn, and a control cable is attached to the rotating drum wound in a direction opposite to that of the flexible tube but for only one turn, around the small idler pulley and in the opposite direction on the fixed drum for two turns to which the other end of the control cable is attached.

Abstract: A system by which in situ observations of optical damage induced in optical omponents by intense thermal radiation may be made. The process includes the determination of the spectral transmission wherein a scanning monochromator is used to illuminate the sample elements with a light beam of monotonically changing wavelength, and the transmitted light is detected and its intensity recorded as a function of wavelength. Optical damage is detected by the resultant changes in the spectral transmission curve.
