Publication number: 20020186745Abstract: A radiation detector for axillary temperature measurement comprises a wand having an axially directed radiation sensor at one end and an offset handle at the opposite end. The radiation sensor is mounted within a heat sink and retained by an elastomer in compression. The radiation sensor views a target surface through an emissivity compensating cup and a plastic film. A variable reference is applied to a radiation sensor and amplifier circuit in order to maintain full converter resolution over design ranges of target and sensor temperature with the sensor temperature either above or below target temperature.Type: ApplicationFiled: April 30, 2002Publication date: December 12, 2002Applicant: Exergen Corp.Inventors: Francesco Pompei, Janus Ternullo

Patent number: 6100527Abstract: A thermally differentiable pattern such as hot melt adhesive is monitored in a production line system. An electrical output from a thermopile radiation sensor is applied to a detection circuit which processes the sensor electrical output to perform an inverse to the sensor transfer function and to perform a differentiation which provides a pulsed output at rising and falling edges of the sensor signal. Comparators provide respective output pulse signals representing the respective rising and falling edges. An adjustable amplifier in the circuit adjusts pulse threshold relative to sensed radiation.Type: GrantFiled: April 13, 1999Date of Patent: August 8, 2000Assignee: Exergen CorporationInventors: Francesco Pompei, Janus Ternullo

Patent number: 5653239Abstract: Temperature of a subject is continuously monitored using a remote sensor assembly mounted in a subject's ear canal. The remote assembly connects to a display housing which contains the temperature display and supports electronics for responding to the sensed radiation. In one configuration, the major components of the remote assembly include a radiation detector, a plug structure and a flexible extension. The radiation detector has a thermopile and a first temperature sensor in close thermal contact with a thermopile junction. The flexible extension connects the radiation detector with the plug structure. Because the flexible extension bends to the contours of an ear canal, the remote sensor assembly extends well into a subject's ear canal without discomfort. The plug structure is molded to fit securely in the concha region of an ear canal and includes a second temperature sensor which senses the temperature therein.Type: GrantFiled: September 7, 1995Date of Patent: August 5, 1997Assignee: Exergen CorporationInventors: Francesco Pompei, Janus Ternullo, William W.

Patent number: 5229612Abstract: A radiation detector employs a thermopile having a potentiometer for calibrating the thermopile output to best suit a particular output meter and sensing application. A thermocouple may be connected in series with the thermopile. The output of the thermopile is calibrated to best match a linear function which intersects the thermopile output function at a temperature in the center of a temperature range of interest. A total output signal of the detector is the sum of the thermopile signal and the thermocouple signal, and is indicative of the temperature of a target emitting radiation sensed by the thermopile. The series connection of the thermopile and the thermocouple allow the thermopile hot junction temperature to be referenced to the cold junction temperature of the thermocouple. Thus, the reference temperature may be remote from the thermopile sensor. A filtering lens may be used to prevent short wavelength radiation from reaching the thermopile sensor, improving the linearity of the thermopile response.Type: GrantFiled: June 14, 1991Date of Patent: July 20, 1993Assignee: Exergen CorporationInventors: Francesco Pompei, Janus Ternullo
