Abstract
In one aspect of the invention, a dual-mode infrared/radio frequency (IR/RF) transmitter is secured within a wristband worn by the mother and within an ankle and/or wristband worn by the infant. In a matching mode of operation, IR signals are received by infrared receivers located within the various rooms of the hospital to precisely and automatically determine by proximity that mother and infant arc correctly united. In a presence detecting mode, RF signals from the infant's badge are detected by RF receivers located throughout the maternity ward of the hospital or throughout the hospital generally. It a security mode, RF receivers located proximate exits of either of the maternity ward and/or the hospital detect RF signals from the ankle and provide a signal to generate an alarm.
