Abstract
Disposable articles such as diapers, incontinent briefs, diaper holders and/or inserts, training pants, feminine hygiene garments, tampons, and the like, having a responsive system. The article includes a sensor that detects an input, an actuator that is adapted to perform a responsive function upon the input, and a feedback control loop in which the actuator is adapted to perform the responsive function upon the input when the sensor detects the input.
Claims29
A disposable article to be fitted to a wearer comprising:
- (a) a responsive system including:
- (i) a sensor operatively connected to said article, said sensor being adapted to detect an input,
- (ii) an actuator operatively connected to said sensor, said actuator being adapted to perform a responsive function upon said input, said actuator comprising a distinct component from said sensor, and
- (iii) a feedback control loop in which said actuator is adapted to perform said responsive function upon said input when said sensor detects said input.
A disposable article to be fitted to a wearer comprising:
- (a) a responsive system including:
- (i) a sensor operatively connected to said article, said sensor being adapted to detect an input associated with feces,
- (ii) an actuator operatively connected to said sensor, said actuator including a compressed resilient material constrained in a vacuum sealed film, said actuator being adapted to encapsulate feces, and
- (iii) a feedback control loop in which said actuator is adapted to encapsulate feces when said sensor detects feces.
A disposable article to be fitted to a wearer comprising:
- (a) a responsive system including:
- (i) a sensor operatively connected to said article, said sensor being adapted to detect an input associated with a bodily waste;
- (ii) an actuator operatively connected to said sensor, said actuator including a compressed resilient material constrained in a vacuum sealed film;
- and
- (iii) a feedback control loop in which said actuator is adapted to absorb said bodily waste when said sensor detects said bodily waste.
A disposable article to be fitted to a wearer comprising:
- (a) a responsive system including:
- (i) a sensor operatively connected to said article, said sensor comprising a pH sensitive film,
- (ii) an actuator operatively connected to said sensor, said actuator including a pH control agent, and
- (iii) a feedback control loop in which said actuator is released when said sensor detects a pH level outside a target range.
