A method and apparatus for distributing, generating, and redeeming discount Virtual Coupons TM , rebate or gift certificates or the like which may be used on conjunction with a frequency card program or the like. Virtual Coupons TM may be distributed electronically, for example, in the form of a diskette or CD-ROM software. Software on the diskette or CD-ROM may prompt a consumer to call a 1-800 number for a validation number or code. During the phone call, telemarketing personnel may request consumer demographic and or identification information which may be entered into a centralized database. Once the software is validated, a consumer may print out a list selected Virtual Coupons TM displayed on a Graphical User Interface (GUI). When a product is purchased, the UPC code of the product may be compared electronically with a list of Virtual Coupons TM authorized for a particular consumer. An appropriate coupon discount may then be applied and the Virtual Coupon TM may be considered "redeemed". Once redeemed, consumer ID information and Virtual Coupon TM information may be retrieved electronically and used to update a central database. Accurate data may then be produced illustrating which consumers or groups of consumers are redeeming which Virtual Coupons TM . Such data may be used for marketing purposes or to generated further diskettes for distribution targeting specific consumers or groups of consumers with specific classes of Virtual Coupon TM offerings. The use of Virtual Coupons TM eliminates or reduces fraud, and allows a frequency card discount to be applied only a limited number of times.

An elimination-absorber monitoring system addresses diaper-monitoring problems with a unique, low cost, multi-layer disposable sensor structure that absorbs small volumes of urine, yet allows most urine volume to flow unimpeded through it, and into the diaper below. When connected with a reusable, miniature monitor / indicator unit, the sensor presents a clear and on-going change of measurement condition upon experiencing a rapid influx into the diaper of a significant volume of urine, and / or upon a significant reduction in the available absorbency of the diaper's top surface. The sensor additionally provides recessed, protected elements for similarly presenting a clear and on-going change in measurement condition upon experiencing the presence of fecal matter. Further provided is the monitor unit employing narrow, widely-spaced, fast rise-time, fast transition-time pulses for conductivity measurement and alarm activation. The monitor and sensor are interconnected and attached to a diaper by particularly effective and unique means, and the monitor is equipped with a highly intuitive and convenient control interface, as well as improved assemblies for the transmission of audible and visual alarm indications. Also described is a convenient test-strip device which, when connected to the monitor / alarm unit of the system, can selectively simulate either a soiled or unsoiled elimination-absorber / sensor for test, caregiver-training or demonstration purposes.
