Abstract: A lavatory includes a partition wall movable along a defined path between a deployed position in which the partition wall divides the lavatory into two discrete areas and a stowed position that defines a combined area in place of the two discrete areas. The partition wall translates along the defined path between the deployed position and the stowed position.

Abstract: A directional radiation detection system and an omnidirectional radiation detector. The omnidirectional radiation detector detects radiation comprising at least one of: (i) gamma rays; and (ii) neutron particles. A radiation scatter mask (RSM) of the radiation detection system includes a rotating sleeve received over the omnidirectional radiation detector and rotating about a longitudinal axis. The RSM further includes: (i) a fin extending longitudinally from one side of the rotating sleeve; and (ii) a wall extending from the rotating sleeve and spaced apart from the fin having an upper end distally positioned on the rotating sleeve spaced apart or next to from a first lateral side of the fin and a lower end proximally positioned on the rotating sleeve and spaced apart from or next to a second lateral side of the fin.

Abstract: A radiation imaging system images a distributed source of radiation from an unknown direction by rotating a scatter mask around a central axis. The scatter mask has a pixelated outer surface of tangentially oriented, flat geometric surfaces that are spherically varying in radial dimension that corresponds to a discrete amount of attenuation. Rotation position of the scatter mask is tracked as a function of time. Radiation counts from gamma and/or neutron radiation are received from at least one radiation detector that is positioned at or near the central axis. A rotation-angle dependent detector response curve (DRC) is generated based on the received radiation counts. A reconstruction algorithm for distributed radiation source(s) and/or localized source(s) are applied based on the tracked rotation position and prior characterization of the detector response for a given scatter mask. A two-dimensional image with relative orientation and source distribution is generated from the measured DRC.

Abstract: Disclosed is an video/audio player/receiver with an integrated digital recorder that improves over conventional digital audio or video playback devices commonly found in automobiles and the like. The present invention improves over conventional car audio technology by providing an otherwise conventional CD player for automotive use with a built-in magnetic media hard drive of a capacity sufficient to store the music of several CDs. By storing a variety of chosen individual songs or entire CDs on hard drive they are ready for instant playback, eliminating the need to carry several CDs and their cases, while still allowing the users to have their favorite songs at their fingertips.
