First Claim
1. A girth monitoring belt (12) assembly, said assembly comprising:
- a flexible belt (12) having first (14) and second (16) ends, buckle means (18) attached between said first (14) and second (16) ends of said belt (12) for securing said belt (12) about the girth of a wearer, a control enclosure (20) connected in series with said buckle means (18) and said belt (12), control means (26) being housed within said control enclosure (20) and responsive to forces on said belt (12) applied by expansion of the wearer'"'"'s girth for moving past a predetermined set point, signal means (38,
40) responsive to said control means (26) moving past said predetermined set point for producing a control signal, said signal means (38,
40) including actuator means (42,
43) responsive to said control signal for indicating the presence of said control signal, and said control means (26) including manual adjustment means (55,
56) for varying the sensitivity of said control means (26) by manually setting said predetermined set point for varying the amount of movement required of said control means (26) to provide said control signal.

Abstract
A girth monitoring belt includes a belt (12) and buckle (18) connected in series with a control enclosure (20). The control enclosure (20) includes a pair of springs (28) connected at one of their ends to the control enclosure (20) and connected at their other ends to an arm (34) which extends from within the enclosure (20) to outside the enclosure where it is connected to the belt (12). As a wearer'"'"'s abdominal muscles expand, the springs (28) expand allowing the arm to slide along the enclosure (20). An electronic control circuit (38, 40) senses movement of the arm (34) past a predetermined set point which actuates an alarm (42, 43) indicating to the wearer of the undersirable condition so that the wearer will contract his muscles and allowing the springs (28) to contract moving the arm (34) within the predetermined set point turning off the alarm (42, 43). The predetermined set point is manually adjustable to vary the overall sensitivity to the amount of movement allowed.
