Patent ID: 7250847

Claim:
A portable mat member for guaging walking maneuvers and coordination maneuvers over the upper surface of such mat comprising: (a) a longitudinally extending mat member having an upper surface and a lower surface, said mat member having a first lateral edge and a second lateral edge, and said mat member having a first end edge and a second end edge, with said first lateral edge being thicker than said second lateral edge; (b) longitudinally extending marking means for guiding walking maneuvers over the surface of said mat member, said marking means extending longitudinally from said first end edge to said second end edge of said mat member wherein said marking means extend upwardly above said upper surface of said mat member and wherein said marking means has a luminous coating over a portion of said marking means; (c) electromechanical pressure sensor means disposed under said longitudinally extending marking means, said sensor means comprising a series of upright resilient spring members located in series under said longitudinally extending marking means, with each of said spring members being interconnected to a movable electromechanical contact member; (d) a mating electromechanical contact member to receive the downward structured contacting movement of said moveable electromechanical contact member which is pressed downwardly to the mating member said circuit having a therein a sound producing member to audibly signal said circuit being closed; (e) circuit means electronically interconnected to each of said mating eletromechanical contact members and having an electrically activated signalling means to detect activation of said electrical circuit by one or more of said mating electromechanical contact members being contacted by one of the said electromechanical pressure sensor means, said closed circuit means having integrated therein an electronically activated signalling device which is activated whenever said circuit is electrically activated by one or more of said electromechanical contact members.
