Wetness awareness training device
First Claim
1. A wetness awareness system comprising:
- an extended length layer of wicking material (45) having a first side and a second side;
an extended length first conductor (41) and an extended length second conductor (43) spaced apart from said first conductor (41), said first and said second conductors (43) attached to said first side of said wicking material (45);
an extended length layer of adhesive attached to said first side of said wicking material (45);
a sensor/transmitter (35) having a first contact (63) for electrical connection with said first conductor (41) and a second contact (79) for electrical connection with said second conductor (43) as a portion of said extended length layer of wicking material (45) is aligned with said first and second contacts (63,
79), and for enabling said first and second contacts (63,
79) into contact with said first and second conductor (43)s, respectively, and including circuitry for detecting the resistance between said first and said second conductors (41,
43) when said wicking material (45) is wet and a transmitter for transmitting a signal indicating a wetness condition of said wicking material (45); and
a receiver (13) for remotely receiving said signal indicating a wetness condition of said wicking material(45).

Abstract
A moisture detection system (11) of the invention provides a disposable wicked dual electrode strip as a sensor wick and conductor assembly (31) which can be used in conjunction with any type of diaper or garment. The dual electrode strip includes two conductive strips (41, 43) which have a wick located in contact with the conductive strips. Even a small amount of urine is absorbed by the wick and distributed between the conductive strips to quickly change the resistance between the strips. A detector/transmitter (35) engages the sensor wick and conductor assembly (31), and can use the sensor wick and conductor assembly (31) as a transmitting antenna for increased range at low power, to alert a receiver (13) carried by a care giver.

10. A transmitter sensor combination comprising:
-
a sensor for mounting inside a garment and having an extended length layer of wicking material (45) having a first side and a second side, and in contact with at least an extended length first conductor (41) and an extended length second conductor (43) spaced apart from said first conductor (41), said first and said second conductors (43) attached to said wicking material (45); an extended length layer of adhesive attached to at least one of directly to and indirectly to said first side of said wicking material (45) to allow said extended length layer of wicking material to adhere to the inside surface of a garment, over an upper rim edge of said garment and partially along an outside surface of said garment forming a fold; a sensor/transmitter (35) having a first contact (63) for electrical connection with said first conductor (41) and a second contact (79) for electrical connection with said second conductor (43) as a portion of said extended length layer of wicking material (45) is formed into a fold over said garment and aligned with said first and second contacts (63,
79), and for enabling said first and second contacts (63,
79) into contact with said first and second conductors (41,43), respectively, and for both mechanical and electrical engagement of said sensor/transmitter (35) with said extended length layer of wicking material (45) and said first and second conductors (41,
43), respectively, and including circuitry for detecting the resistance between said first and said second conductors (41,
43) when said wicking material (45) is wet and a transmitter for transmitting a signal indicating a wetness condition of said wicking material (45). - View Dependent Claims (11, 12, 13)
