Abstract

A non-touch thermometer senses temperature from a digital infrared sensor is described. A microprocessor is operably coupled to a camera from which patient vital signs are determined. A digital signal representing a temperature without conversion from analog is transmitted from the digital infrared sensor. A temporal variation of images is generated from which a heart rate and the respiratory rate can be determined and displayed or stored.
