Tympanic temperature measurements are obtained from the output of a thermopile mounted in an extension from a housing. The housing has a temperature display thereon and supports the electronics for responding to sensed radiation. A disposable plastic sheet taken from a tape of such sheets stretches over the end of the extension between side posts. The thermopile is mounted in a highly conductive thermal mass which includes a waveguide tube. A low conductivity gaseous environment surrounding the thermopile extends through the tube. The electronics include an EEPROM in which both calibration and characterization information may be stored during a calibration procedure through an optical coupling. A capacitor and transistor associated with a switch form a simple watchdog circuit.

Radiation detector suitable for tympanic temperature measurement

An error-free, data telecommunication system designed for continuous high speed error-free data communications over dial-up voice grade circuits comprising a high speed data transmission section including internal data buffering and a low speed reverse channel ARQ (automatic request for repeat) receiver and a high speed data receiving section including a low speed reverse channel ARQ transmitter whereby high speed data and reverse ARQ signaling are transmitted simultaneously over a two wire dial-up network. The system is capable of half-duplex, two wire operation and full-duplex, four wire operation.
