1. A foot weight alarm device, comprising:

  • a) a power supply which provides a regulated voltage;

    b) at least one resistive force sensor, said resistive force sensor connected to said power supply and said resistive force sensor having a resistance which varies with the amount of weight applied to said resistive force sensor;

    c) signal conditioning means connected to said resistive force sensor whereby said signal conditioning means produces a voltage-corresponding digital value which varies with the resistance of said resistive force sensor;

    d) calibrating means connected to said signal conditioning means such that said calibrating means converts said voltage-corresponding digital value into a force-corresponding digital value whereby said force-corresponding digital value corresponds to the amount of weight to which said resistive force sensor is subjected;

    e) programming means connected to said calibrating means whereby said programming means sets at least one weight limit in said calibrating means such that said calibrating means can compare said force-corresponding digital value to said weight limit;

    f) alarm generating means which generates an alarm in response to said force-corresponding digital value; and

    g) a housing wherein said signal conditioning means, said calibrating means, and said alarm generating means are housed but with said programming means being external thereto.
