Incontinence detection system

A method for detecting an amount of wetness of an absorbent article, wherein the absorbent article is provided with at least two conductive lines along its length, the method comprising:

• using multiple frequencies, the multiple frequencies being different from each other, and wherein one of the multiple frequencies with highest rise range is used to determine the amount of wetness of the absorbent article.

A system for detecting an amount of wetness of an absorbent article, wherein the absorbent article is provided with at least two conductive lines along its length, the system comprising:

• a detector configured to detect, with a first frequency, an initial liquid touching line that connects two of the conductive lines by a sharp rise on the first frequency and to detect, with a second frequency, an final liquid touching line that connects the two of the conductive lines by a rise on the second frequency;
• and
• a wetness determination unit configured to determine the amount of wetness of the absorbent article by a difference between the initial and final liquid touching lines.

A system for detecting an amount of wetness of an absorbent article, wherein the absorbent article is provided with at least two conductive lines along its length, the system comprising:

• a detector configured to detect, with a frequency, an initial liquid touching line that connects two of the conductive lines and to detect, with the frequency, an final liquid touching line that connects the two of the conductive lines;
• and
• a wetness determination unit configured to determine the amount of wetness of the absorbent article by a difference between the initial and final liquid touching lines with the rise of the frequency.

A system for detecting an amount of wetness of an absorbent article, wherein the absorbent article is provided with at least two conductive lines along its length, the system comprising:

• a detector configured to detect, with multiple frequencies, a final liquid touching line that connects two of the conductive lines, the multiple frequencies being different from each other, and a wetness determination unit configured to use the final liquid touching line detected from one of the multiple frequencies with highest rise range to determine the amount of wetness of the absorbent article.

A wetness detection device with an orientation sensing and alerting function, comprising:

• an orientation sensing unit configured to continuously sense an orientation of a user wearing the wetness detection device;
• and
• a transmitter configured to transmit an alert when the orientation sensing unit fails to sense a change in orientation of the user for a predetermined period.

A method for monitoring a wearer of an absorbent article, wherein the absorbent article is provided with at least two conductive lines along its length, and wherein an attachment device equiped with an orientation detector is coupled to the absorbent article, the method comprises:

• checking the movement of the body of the wearer of the absorbent article with the orientation detector, and sending alert if the wearer does not move in a specified number of time.
