Abstract
A system for monitoring an infant-bearing device includes a microprocessor responsive to a resident program. A first circuit connected to the microprocessor and to a sensor automatically activates operation of the microprocessor to a "monitor" mode upon detection of the infant's presence, maintains operation of the microprocessor for a predetermined time period at least equal to a running time of the program and terminates operation of the microprocessor at the expiration of the predetermined time period if termination of the patient's presence occurs prior to expiration of the predetermined time period. A second circuit operates the system in response to signals received from a remote control device to deactivate the system from the "monitor" mode. The microprocessor is further responsive to the first circuit to activate the system to the "monitor" mode after deactivation if the sensor subsequently detects termination and resumption of the infant's presence on the device. A third circuit connected to the microprocessor provides an audio/alarm upon demand by the microprocessor. The microprocessor is responsive to the first circuit to switch the system from the "monitor" mode to an …
