Document Type and Number:
Japanese Patent JP2809503
Kind Code:
B2
Abstract:
Tympanic temperature measurements are obtained from the output of a thermopile (28) mounted in an extension (18) from a housing (14). The housing (14) has a temperature display (16) thereon and supports the electronics for responding to sensed radiation. A disposable plastic sheet (42) taken from a tape of such sheets stretches over the end of the extension (18) between side posts (52,54). The thermopile (28) is mounted in a highly conductive thermal mass (34,36) which includes waveguide tube (32). A low conductivity gaseous environment surrounding the thermopile (28) extends through the tube (32). The electronics include an EEPROM (100) in which both calibration and characterisation information may be stored during a calibration procedure through an optical coupling (104). A capacitor (C1) and transistor (T1) associated with a switch (22) form a simple watchdog circuit.
