## Abstract

An incontinence detection system monitors an area for moisture events and wirelessly transmits moisture-related information to one or more notification devices. The system has a pad that includes a substrate and one or more sensors supported by the substrate. The sensor(s) emit wireless signals indicative of the moisture-related information. A sensor event communication system forwards the sensor signals to another device, such as a notification device. Portions of the system are included in a patient support apparatus, such as a bed.

## Claims

### Claim 1

A method of manufacturing an incontinence detection pad, the method comprising
unrolling a continuous roll of backsheet material having a series of electrode traces printed thereon, each electrode trace on the continuous roll having a sacrificial trace portion,
attaching an RFID tag to a pair of terminal ends of a first trace electrode of the series of electrode traces,
testing the first electrode trace by exciting the RFID tag with energy to confirm that the first electrode trace forms a completed short circuit between the terminal ends of the first electrode trace, and
cutting the backsheet material at a location which severs the sacrificial trace portion from the rest of the first electrode trace, thereby leaving a pair of spaced moisture detection electrode traces on a first backsheet for a first incontinence detection pad and leaving the sacrificial trace portion behind on a trailing, second backsheet for a second incontinence detection pad.

### Claim 2 (depends on 1)

The method of claim 1, further comprising laminating an absorbent core to a top sheet to form a laminate and attaching the laminate to the backsheet to sandwich the absorbent core between the top sheet and the backsheet.

### Claim 3 (depends on 2)

The method of claim 2, wherein the laminate is attached to the backsheet after testing the first electrode trace by exciting the RFID tag with energy.

### Claim 4 (depends on 2)

The method of claim 2, wherein the laminate is attached to the backsheet before testing the first electrode trace by exciting the RFID tag with energy.

### Claim 5 (depends on 2)

The method of claim 2, wherein laminating the absorbent core to the top sheet comprises using a lined, combed, slot coating process to deposit glue in substantially parallel rows on the top sheet.

### Claim 6 (depends on 5)

The method of claim 5, wherein the substantially parallel rows of glue deposited on the top sheet are each about 1 mm wide with a spacing between the parallel rows of about 4 mm.

### Claim 7 (depends on 1)

The method of claim 1, wherein attaching the RFID tag to the pair of terminal ends of the first trace electrode of the series of electrode traces comprises removing the RFID tag from a roll of material carrying a series of RFID tags and adhering the RFID tag to the backsheet material.

### Claim 8 (depends on 1)

The method of claim 1, further comprising storing an identifier of the RFID tag of any incontinence pad for which the first electrode trace does not form a completed short circuit between the terminal ends of the first electrode trace as determined by the testing, whereby the identifier indicates a rejected incontinence detection pad.

### Claim 9 (depends on 8)

The method of claim 8, further comprising exciting the RFID tag with energy a second time to read the identifier of the rejected incontinence detection pad and scrapping the rejected incontinence detection pad by removing it from a manufacturing line.

### Claim 10 (depends on 9)

The method of claim 9, further comprising folding the backsheet, the absorbent core, and the top sheet before exciting the RFID tag with energy the second time.

### Claim 11 (depends on 10)

The method of claim 10, wherein cutting the backsheet material at the location which severs the sacrificial trace portion from the rest of the first electrode trace occurs after the backsheet, absorbent core, and top sheet are folded and before exciting the RFID tag with energy the second time.

### Claim 12 (depends on 1)

The method of claim 1, further comprising adding a mark to any incontinence pad for which the first electrode trace does not form a completed short circuit between the terminal ends of the first electrode trace as determined by the testing, whereby the mark indicates a rejected incontinence detection pad.

### Claim 13 (depends on 12)

The method of claim 12, wherein the mark becomes visible when exposed to ultraviolet (UV) light.
