Abstract: A pause point during consumption of media data is identified. The pause point is a point at which identify a user stops the consumption of the media data. A portion of content preceding the identified pause point is determined. The portion of content is analyzed to identify changes in content concepts in the portion of content. One or more continuation points for the user to return to the content based on changes in the content concepts in the portion of content are identified. The one or more continuation points are indicated to the user.

Abstract: A method, apparatus, article of manufacture, and a memory structure for controlling an attitude and a nutation of a spacecraft spinning about a first axis. The method comprises the steps of measuring a spacecraft attitude rate &ohgr;1(t) about a second axis substantially orthogonal to the first axis; generating a rate correction value &agr;&ohgr;1(t)/&lgr;0, wherein &lgr;0 is an inertial nutation frequency of the spinning spacecraft, and &agr; is a proportionality factor; determining a spacecraft attitude angle &phgr;2(t) about a third axis substantially orthogonal to the first axis and the second axis; generating an error signal e(t) as &phgr;2(t)+&agr;&ohgr;1(t)/&lgr;0; and applying a torque to rotate the spacecraft along the second axis. The article of manufacture comprises a program storage device storing instructions implementing the instructions described above.
