1. A computer program device comprising:

  • a computer program storage device readable by a digital processing apparatus; and

    a program means on the program storage device and including instructions executable by the digital processing apparatus for performing method steps for defining time sequence shape criteria and identifying electronically stored time sequences satisfying the shape criteria, the method steps comprising;

    (a) defining a set of elemental shapes;

    (b) defining a desired time sequence shape using the elemental shapes or combinations thereof;

    (c) mapping intervals of a time sequence to corresponding transition sequences, each transition sequence corresponding to one or more elemental shapes or combinations thereof that describe a respective interval of the time sequence;

    (d) identifying one or more transition sequences that match the desired time sequence shape; and

    (e) outputting parameter values representative of the one or more transition sequences that match the desired time sequence shape.
