A monitoring system identifies a wet diaper by embedding an inexpensive disposable passive humidity sensor, and attaching to the outside of the diaper a detachable transmitting module that is triggered into transmission by the humidity sensor. The transmitting module is sealed and transferable from the wet diaper to a dry one. Uniquely coded data is wirelessly transmitted to a remote receiver. The receiver may be a battery powered portable unit carried by the baby's guardian. In a day care center a multiple function receiver can identify any of several diapers. In hospitals, several strategically located receivers are each capable of recognizing and reporting any wet diaper within its range to a central computer. Low cost and long range are achieved by using a detachable and transportable active transmitter that is not discarded with the wet diaper and therefore can be re-used. False transmissions are prevented by a confirmatory resistance.

A single use sterile slit impact sampling cassette with rotatable capture tray for recovering particulate matter from ambient air, having a lid with a slit shaped air inlet, dish with an air outlet, and capture tray. The dish and lid assemble to form a sealed sample chamber, which houses the capture tray. The assembled cassette is sterile packaged with its inlet and outlet covered before use. The cassette is placed on a base for operation, which supplies the required vacuum for sampling, and rotational means for the capture tray. Air drawn into the air inlet is accelerated to a velocity that ensures impingement, or entrainment of particulate matter from the sampled air volume onto, or within the capture media. The sampled air volume is evacuated from the sample chamber through an air outlet. The cassette is then removed from the operative base, and then may be analyzed for the target contaminants.
