System and method for detecting movement of an infant from a secure area
First Claim
1. A system for detecting the passage of an infant from a secure area comprising:
- (a) a first diaper adapted to be worn by an infant in the secure area, said first diaper comprising,(1) means for presenting a conspicuous appearance so that said first diaper is adapted to be visually distinguished from diapers not having said present means, and(2) indicator means embedded in said first diaper so that the presence of said indicator means is not sensed by an infant wearing said first diaper for causing a signal to be generated indicating passage of said first diaper from the secure area;
(b) detector means positioned adjacent openings to the secure area for detecting passage of said first diaper out of the secure area and for generating an electronic signal responsively thereto; and
(c) alarm means for providing an alarm signal responsively to receipt of said electronic signal,so that an infant wearing said first diaper leaving the secure area is detected electronically by said detector means and an infant not wearing said first diaper attempting to evade said detector means can be detected visually by lack of said presenting means.

Abstract
An electronically and visually detectable diaper or article of apparel is used in a system and method for detecting the unauthorized movement of an infant from a secure area in a hospital. The diaper may have electronically detectable indicator tags embedded therein that are detectable by a transmitting and receiving unit positioned adjacent openings to the secure area. The diaper may also include a visually conspicuous appearance to defeat attempts to thwart the electronic detection system. The indicator tags may be positioned in perpendicular planes so that the transmitting and receiving unit may detect the diaper, regardless of the diaper'"'"'s orientation as it passes through the transmitting and receiving unit.

10. A system for detecting the unauthorized passage of an infant wearing an electronically and visually detectable diaper from a secure area, comprising:
-
(a) a first diaper adapted to be worn by an infant in the secure area, said first diaper comprising, (1) means for presenting a conspicuous appearance so that said first diaper is adapted to be visually distinguished from diapers not having said presenting means, and (2) two water resistant resonance circuits embedded in said first diaper and positioned so that when said first diaper is being worn said two resonance circuits are in nearly perpendicular planes, for causing a signal to be generated indicating passage of said first diaper from the secure area, each of said two resonance circuits comprising a flexible substrate for allowing said two resonance circuits to conform to the shape of said first diaper so that the presence of said circuit in said first diaper is not sensed by an infant wearing said first diaper; (b) detector means for detecting said resonance circuits and for generating an electronic signal indicative of the presence of said first diaper adjacent said detector means, said detector means being positioned adjacent each passage into and out of the secure area, said detector means comprising a first transmitter for transmitting a first signal and a first receiver for receiving a second signal, and each of said resonance circuits comprising a second receiver for receiving said first signal and a second transmitter for transmitting said second signal when said second receiver receives said first signal; and (c) alarm means for providing an alarm signal in response to receipt of said electronic signal from said detector means, so that an infant wearing said first diaper leaving the secure area causes an alarm signal indicating unauthorized passage of an infant from the secure area, and an infant not wearing said first diaper in the secure area attempting to evade said detector means can be detected visually by lack of said presenting means.

11. A system for detecting the passage of an infant from a secure area, comprising;
-
(a) an article of apparel to be worn by an infant in the secure area; (b) a passive resonating circuit hidden within said article of apparel; (c) transmitting means for generating an electronic signal spanning an egress from the secure area, said electronic signal causing said circuit to resonate when the circuit is passed through said signal; (d) receiving means for detecting said signal and for detecting resonance in said signal and for detecting resonance in said passive resonating circuit; and
,(e) an annunciator means, operatively connected to said receiving means, for indicating the detection of resonance in said passive resonating circuit by said receiving means. - View Dependent Claims (12)

13. An electronically detectable diaper for a system for detecting unauthorized removal of an infant from a secure area comprising:
-
a diaper adapted to be worn by an infant in the secure area; and two resonance circuits embedded in said diaper and positioned so that when said diaper is being worn said two circuits are in nearly perpendicular planes, for causing a signal to be generated indicating passage of said diaper through an opening to the secure area, each of said two circuits comprising a flexible substrate for allowing said circuits to conform to the shape of said diaper so that the presence of said circuits is not sensed by an infant wearing said diaper. - View Dependent Claims (14)
