Abstract
A bed mat having a sensor for detecting abnormally high temperatures and for detecting when the occupant of the bed is not in it is connected to a control console which has circuits for producing a first electrical signal having a first characteristic in response to the detection of an abnormally high bed temperature and a second signal having a second characteristic in response to the detection of the absence of the bed occupant. In one form of the invention, these signals are applied to the conventional nurse call system to produce sensory signals at the nurses' station, for example, indicative of the detection of high temperature or absence in a way such that they can each be distinguished from the the signal produced at the nurse's station by the use of the nurse call button by the patient. Provision is also made for coupling of a smoke detector into the system for actuating the high temperature alarm signaller if smoke is detected.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
