Claim:
A memory assist device with an indicia field to indicate a number, the memory assist device comprising: (a) at least two filaments extending between internal walls of the memory assist device to form the indicia field; and (b) clips selectively clamped on the filaments to indicate the number, wherein each of the clips comprises: (b1) an upper member having at least two sets of upper teeth; (b2) a lower member having at least two sets of lower teeth, wherein each set of upper teeth contacts a set of lower teeth when the clamp is in a clamped position such that at least one set of lower teeth and the set of upper teeth which the lower set of teeth clamps onto at least one of the filaments; and (b3) a torsion spring attached to spring mounts on the lower member and the upper member, wherein the torsion spring biases the upper teeth against the lower teeth when the clamp is in the clamped position and wherein moving ends of the upper member toward ends of the lower member causes the clamp to move from the clamped position to an unclamped position.
