A vital signs monitor comprising a first device capable of being disposed at a selected location on a patient to pass at least exhaled gases therethrough; a second device coupled to the first device to perform a plurality of resistive measurements of certain predetermined parameters of the exhaled gases and a plurality of optical absorption measurements of other predetermined parameters of the exhaled gases; and a third device coupled to the second device responsive to the plurality of resistive measurements and the plurality of optical absorption measurements to provide individual read outs of at least a value of carbon dioxide in the exhaled gases, a value of tidal volume of the exhaled gases and a value of a respiration rate of the patient.

Vital signs monitor

In a first embodiment, the device is in the form of a face mask for affixing to the face of a patient to monitor the patient's respiration. It is self-powered and self-contained so that such respiration can be monitored all the while the patient is being transported. It incorporates light-emitting diodes which are illuminated, sequentially, to evidence regular breathing. When the patient stops breathing, the diodes do not illuminate, and an audible alarm is sounded to make medical personnel immediately aware of the breathing cessation.

Respiration-signalling device

A motion and intrusion detecting system wherein scanning at two different rates is carried out in order to more reliably detect fast and slow motion in a scene being viewed. Also, increased noise immunity is provided by providing a special scan which generates signals inhibiting generation of alarm indications corresponding to points at which a possible noise situation exists.

Motion and intrusion detecting system

A motion and intrusion detection system utilizing video techniques samples fixed points during a video scan of the field of view of a camera and stores information concerning the fixed scanned points. During subsequent scans, information concerning the respective scanned points is compared with previous scans and threshold conditions are set up in order to detect an alarm condition. Further, apparatus is provided to change the field of view of the video system and in order to automatically focus and zoom in to magnify a particular portion of the field of view. Still further, means is provided to display a 'map' of the alarmed areas on the screen of the television monitor.
