Abstract: A winding stem mechanism including a winding shaft having a detent portion comprised of a pair of annular peripheral recesses with an annular step portion therebetween, and a pair of annular stops each adjacent a respective one of the recesses, and mounted for rotation and for being axially slidable. A resilient spring-like member normally engages a first of the recesses to define a normal position of the shaft and when the shaft travels in a first axial direction the spring-like member climbs the annular step portion to engage the second of the recesses. When the shaft travels in a second axial direction it pushes the annular stop adjacent the first recess to flex the spring-like member to permit the shaft to travel to a second operating position and flex in a direction effective to bias the shaft back from the second operating position to the normal position when the shaft is released.

Abstract: This speech recognizer concatenates a string of reference isolated-words for comparison with the unknown string of connected-words. The invention includes a level-building (LB) algorithm, "level" implying a location in a sequence of words. A constrained endpoint dynamic-time-warp algorithm, in which the slope of the warping function is restricted between 1/2 and 2, is used to find the best alignment between an unknown continuous-word test pattern, and a concatenated sequence of L reference patterns. Properties of the LB algorithm include: modification of the references; back-track decision logic; heuristic selection of multiple candidates, and syntax constraints. As a result, the processing required is less than two-level dynamic-program-matching and sampling algorithms.
