Abstract

An expansion indicator device is used around a waist of a user to indicate whether a threshold amount of stomach cavity expansion is achieved as the user breathes and includes a strap, a power source, a feedback indicator and a switch assembly. The strap is fabricated from a stiff yet flexible material and is sized and adapted to be secured around the waist of the user. The feedback indicator is operative between an activation state whereby the power source is connected to the feedback indicator thereby energizing the feedback indicator and a de-activation state whereby the power source is disconnected from the feedback indicator thereby de-energizing the feedback indicator. The switch assembly interconnected to the power source and the feedback indicator and is operatively connected to the strap so that, as the user breathes, the switch assembly is operative to move between a closed condition and an opened condition. When the threshold amount of stomach cavity expansion is reached, the feedback indicator moves to the closed condition and becomes energized to the activation state. When the amount of stomach cavity expansion falls below the threshold amount, the feedback indicator moves to the opened condition and becomes de-energized to the de-activation state.

Dependent claims

An expansion indicator device adapted for use around a waist of a user to indicate whether a threshold amount of stomach cavity expansion is achieved as the user breathes, comprising:

(a) a strap fabricated from a stiff yet flexible material, said strap sized and adapted to be secured around the waist of the user;
(b) a power source;
(c) a feedback indicator operative between an activation state whereby said power source is connected to said feedback indicator thereby energizing said feedback indicator and a deactivation state whereby said power source is disconnected from said feedback indicator thereby de-energizing said feedback indicator;
and
(d) a switch assembly interconnected to said power source and said feedback indicator and operatively connected to said strap so that, as the user breathes, said switch assembly is operative to move between a closed condition whereby, when the threshold amount of stomach cavity expansion is reached, said feedback indicator becomes energized to the activation state and an open condition whereby, when the amount of stomach cavity expansion falls below the threshold amount, said feedback indicator becomes de-energized to the deactivation state;
said switch assembly including a band of stiffyet flexible material having a pair of band ends disposed opposite one another and a first electrode fastened to said band and electrically connected to one of said power source and said feedback indicator and a strip of elastic material having a pair of strip ends disposed opposite one another and a second electrode fastened to said strip and electrically connected to a remaining one of said power source and said feedback indicator, said band and said strip connected to each other at respective ones of said band ends and strip ends so that, when said switch assembly is in the opened condition, said strip is in a relaxed state and said band is in a bowed state thereby separating said first and second electrodes in a spaced-apart, facially-opposing relationship from one another and, when said switch is in said closed condition, said strip is in a stretched state and said band is in a straightened state thereby causing said first and second electrodes to contact each other.

An expansion indicator device adapted for use around an expandable body to indicate whether a threshold amount of body expansion is achieved as the body expands, comprising:

(a) a strap fabricated from a stiff yet flexible material, sized and adapted to be secured around the expandable body;
(b) a power source;
(c) a feedback indicator operative between an activation state whereby said power source is connected to said feedback indicator thereby energizing said feedback indicator and a de-activation state whereby said power source is disconnected from said feedback indicator thereby de-energizing said feedback indicator;
and
(d) a switch assembly interconnected to said power source and said feedback indicator and connected to and operative with said strap so that, as the body expands, said switch assembly is operative to move between a closed condition whereby, when the threshold amount of body expansion is reached, said feedback indicator becomes energized to the activation state and an open condition whereby, when the amount of stomach cavity expansion falls below the threshold amount, said feedback indicator becomes de-energized to the deactivation state;
said switch assembly including a band of stiff yet flexible material having a pair of band ends disposed opposite one another and a first electrode fastened to said band and electrically connected to one of said power source and said feedback indicator and a strip of elastic material having a pair of strip ends disposed opposite one another and a second electrode fastened to said strip and electrically connected to a remaining one of said power source and said feedback indicator, said band and said strip connected to each other at respective ones of said band ends and strip ends so that, when said switch assembly is in the opened condition, said strip is in a relaxed state and said band is in a bowed state thereby separating said first and second electrodes in a spaced-apart, facially-opposing relationship from one another and, when said switch is in said closed condition, said strip is in a stretched state and said band is in a straightened state thereby causing said first and second electrodes to contact each other.
