Abstract: An electrical pop out device has a shroud and an outlet housing. The outlet housing is sized to be placed inside the shroud. A guidance mechanism connects the outlet housing with the shroud. The guidance mechanism includes multiple rack gears and multiple pinion gears. The outlet housing is moveable with respect to the shroud along a direction defined by the rack gear. A spring connector electrically couples the shroud to the outlet housing.

Abstract: A method and apparatus for imaging an object including the steps of projecting radiation from a radiation source through an object and moving the radiation source through multiple imaging positions relative to the object without stopping movement of the radiation source. Movement is accomplished while projecting radiation at more than one of the imagining positions with the source having a source velocity for at least one imaging position that is different from a source velocity for a second imaging position. Radiation transmitted through the object is also detected. Radiation may be projected while moving the radiation source through the multiple imaging positions. In addition, the velocity at which the radiation source is moved through a select imaging position may be related to a resolution desired for data collection at the select imaging position. The velocity of the radiation source may be varied within a select imaging position.

Abstract: A piston-type passenger conveying system includes at least three cabs to move between two floors. A control moves the cabs such that a cab is always waiting at each of said floors, and another cab is always moving to a floor. In this way, the system achieves the passenger flow benefits of an escalator with the inherent benefits of an elevator system.

Abstract: A rotating passenger conveying system includes a central rotating column which drives a number of cabs to rotate about an axis. The cabs are also movable along the axis between a first and second floor. The central column rotates continuously, and the cabs are cyclically moved between the two floors. Passengers can enter a cab at one of the floors, and cab will then rotate to a movement zone. In the movement zone the cab will move to the other floor. The movement and flow of passengers in this system is continuous, and thus, the throughput of passengers in the rotating passenger conveying system is closer to an escalator system than to an elevator.

Abstract: A multiple-size cervical collar is disclosed which is formed from a stiff flexible plastic material and comprises (a) a neck encircling band comprising a front portion and a back portion and (b) a mandible support formed from such plastic material. The mandible support is vertically shiftable with respect to the neck band and lockable thereto at a discrete number of positions to match standard single-sized collars and thereby accommodate various sizes of wearers to which the collar is applied.

Abstract: An X-ray apparatus is disclosed comprising an angularly adjustable parallelogram formed by two members parallel to a central axis and two members transverse the central axis. A radiation source and a radiation receptor are positioned at one end of the respective parallel members. The apparatus is characterized in that the two transverse members are disposed on opposite sides of the central axis, and one end of both parallel members is offset to the same side of the central axis.
