A coded card for use in a melody playing apparatus. The coded card has four quadrants, each quadrant having a different melody therein. A synchronization code is encoded down the center of the card between alternates ones of the quadrants. By alternately rotating and turning the card over, each of the four quadrants with different melodies and the synchronization code will appear at a same predetermined quadrant position. Therefore, when playing on the melody playing apparatus, each of the melodies can be decoded thereby.

Coded card for use in a melody playing apparatus

A method and apparatus for determining distance from a bow to a target at which the bow is aimed in which a beam of collimated light from a laser is directed to the target and reflected to a linear photosensitive element mounted on the bow. The element and laser are positioned on the bow so that the linear position of the incident reflected beam varies with the target distance and the element produces an output indicating the position. A circuit receives that output and produces a display of the target distance.
