ABSTRACT:
Apparatus is configured to provide an alarm perceivable by a user when an increase in a level of force applied to a foot exceeds a threshold value determined by a variable resistance. The level of force is determined from a pressure established within a transducer in an insole placed, for example, within the shoe of the user. This pressure is converted into an electrical signal within a pressure transducer within a control box. This electrical signal charges a capacitor to produce a voltage which is compared with a voltage level corresponding to the threshold value. The result of this comparison is used to determine when the alarm is provided.
