Abstract: Techniques for generating and outputting a natural language explanation of a determination made by a system are described. The system presents content to a user, where the content is generated based on a system determination. The system determines history data associated with a user profile associated with the user and context data associated with the system determination. The system uses the history data and the context data to determine a natural language explanation that the output was generated based on the system determination. The system further uses the history data and the context data to generate a predicted system determination representing the system determination that resulted in the output presented to the user. Based on a similarity between the predicted system determination and the actual system determination, the natural language explanation is presented to the user.

Abstract: A long-distance learning system includes an instruction studio and one or more remotely located classrooms for students. Each of the student's participation, academic performance, and use of digital resources for a class is evaluated in real time and assigned a color, so the instructor can easily assess each student's progress in the class when presented to the instructor in a display which is only for the instructor.

Abstract: A portable knockdown table assembly has a separable collapsible slatted tabletop supported on a collapsible base in a setup condition. A pair of bag retaining straps carried by a tabletop slat releasably retain a disposable trash bag in a depending and open condition at one end of the table when the table assembly is setup and may also be employed to releasably secure the slatted tabletop in its collapsed or bundled condition when the table assembly is in its knockdown condition.

Abstract: A portable sling chair having a frame formed by a plurality of rigid axially elongated collapsible tubular frame members including a main frame member and a rear frame member connected for pivotal and axial sliding movement relative to each other, a collapsible front support member, a collapsible frame front support assembly, a collapsible frame rear support assembly, and at least one connecting member connecting the main frame member and the rear frame member to maintain the frame in a substantially static condition when the frame is resting on a supporting surface in setup condition. A rectangular panel made from flexible material is supported at its opposite ends by collapsible front and rear panel support members, extends therebetween, and defines contiguous chair seat and back portions when the frame is in its setup condition. All of the frame members are disposed in generally side-by-side relation to each other in the collapsed condition of the frame and form a compact bundle.

Abstract: A folding chair for use on both level and inclined supporting surfaces has a back support and a front leg assembly pivotally connected to a bottom for independent forward and rearward movement relative to the bottom and to each other between operative and collapsed positions. A flexible retaining strap of adjustable length maintains the front legs in selected angular position relative to the bottom and holds the bottom in a generally horizontally disposed position when the chair is supported on an inclined surface. A flexible carrying strap of adjustable length maintains the back in a comfortable back supporting position relative to the bottom. Lifting the chair by the carrying strap automatically collapses the chair into a compact bundle which may be carried on a shoulder by the carrying strap. Collapsible rear legs may be provided for supporting the chair bottom at a conventional chair seat height above a supporting surface.
