Abstract: To monitor a patient, a pressure sensor is placed under the patient. The pressure pad includes a normally open switch having first and second contacts. Pressure on the pad over a preset amount arms the switch and release of the pressure causes an alarm and/or a message to be announced. The closing of the first and second contacts requires bending one of the first and second contacts over a spacing means, wherein the spacing means includes at least one spacing member that is at least one-eighth inch in height between the first and second contacts. In this manner, the contacts are held apart until the resilient spacing member is forced shut. The pressure pad is low cost and can be disposable.

Abstract: To monitor a patient, an alligator clip is fastened to the patient by a cord having a length of between five inches and five feet. The other end of the cord is connected to a switch which is activated when the patient moves beyond the length of the cord to cause a message to be announced. A disposable pressure pad is located under the patient and armed by the application of weight to the pad. Upon removal of the weight the alarm is given.

Abstract: To monitor a patient, a combined allegator clip and switch is fastened to the patient by a cord having a length of between five inches and five feet. The other end of the cord is connected to a switch which is activated when the patient moves beyond the length of the cord to cause a message to be announced. If the allegator clip is removed, another circuit activates the alarm to play the voice message and provide an alarm to a caretaker at a remote station. The fastener is an alligator clip having first and second jaws and a spring for biasing said first and second jaws together, whereby said alligator clip may be fastened to clothing. When the jaws are separated by clothing, two conductors are separated but when the jaws contact each other, the conductors are closed to activate the voice message.

Abstract: To generate an alert signal indicating that an unauthorized subject is in a first region within seven feet of a passageway, a radio transmitter is worn by the subject and received by a receiver at the passageway. A second signal is generated upon satisfaction of a second condition, such as an open door at the passageway, which second signal indicates the likelihood of the subject passing through the passageway. A first display indicates if the first signal is present and a second signal if the second condition occurs.
