Abstract: A method executed by a computing device includes determining a set of identigens for each query word of a query to produce sets of identigens, where a set of identigens represents different meanings of a word of the query. The method further includes obtaining a first identigen selection for a first query word from the first set of identigens. The method further includes interpreting, using identigen pairing rules and based on the first identigen selection, the sets of identigens to produce a query entigen group. The method further includes accessing a knowledge database utilizing the query entigen group to produce a response entigen group. The method further includes generating a response to the query using the response entigen group, where the response includes at least one response word.

Abstract: A method executed by a computing device includes determining a set of identigens for each phrase word of a phrase to produce sets of identigens. A set of identigens of the sets of identigens represents one or more different meanings of a phrase word of the phrase. The method further includes obtaining sensor information for one or more phrase words of the phrase. The method further includes selecting an identigen of a first set of identigens based on the sensor information to produce a first identigen selection for the first set of identigens having a selected meaning of one or more different meanings of the first phrase word. The method further includes interpreting remaining sets of identigens of the sets of identigens to produce an entigen group so that the entigen group represents a most likely meaning interpretation of the phrase.

Abstract: A flexible gate is disclosed which comprises a plurality of segments. The segments may be connected by at least one coupling. When the flexible gate is acted on by a force, the flexible gate may flex. When the force is no longer present, the flexible gate may return to a substantially straight position. The segments may be removed or added as needed to repair broken segments or to adjust the length of the flexible gate.

Abstract: A railway switch stand includes a housing with a vertical shaft having a lower end connected to the switch throw rod, the shaft being rotatable to reciprocate the throw rod. A plate is mounted orthogonally on the shaft for rotation with the shaft, and has a plurality of bearings projecting upwardly therefrom around the shaft. A cam follower is mounted to move along a circle with the same radius as the bearings, with a spring mounted above the cam follower to apply a downward biasing force on the cam follower to retain the cam follower between a pair of bearings. A motor has a drive shaft oriented orthogonal to the vertical shaft and includes a drive crank affixed orthogonally to the drive shaft with radially projecting ends. One end of the crank is connected to a U-shaped yoke which in turn is pivotally connected to the cam follower.

Abstract: An adjustable level having an angled base with legs extending normal to one another from a common edge and with magnets spaced along and extending fully through each leg; an L-shaped bracket having at least one bubble housing fixed to a leg thereof; a post extending from the base and through a hole in the bracket; a spring on the post and between a head on the post and the bracket to bias the bracket towards the base and to thereby engage ribs on the bracket into grooves on the base; and a retainer for retaining the level to objects, including a flexible cord connected to a return spring and a loop and hook to secure the cord in a pulled out condition surrounding an object.
