Kenneth G Junkert, Henry P Voznick: Infrared thermometers for minimizing errors associated with ambient temperature transients. Wahl Instruments, Freilich Hornbaker Rosen & Fernandez, February 2, 1988: US04722612 (81 worldwide citation)

A thermopile detector means for a temperature measuring instrument physically and electrically configured to supply an output signal which indicates target temperature substantially independent of the influence of ambient temperature changes. The detector means includes a first thermopile device exp ...

Henry P Voznick: Thermocouple surface probe. Wahl Instruments, Gausewitz Carr Rothenberg & Edwards, June 12, 1984: US04454370 (45 worldwide citation)

A pair of resilient side-by-side elongated coils of different thermocouple material are mounted in a ceramic housing and project forwardly with their forward ends connected to form a thermocouple junction that is adapted to be pressed against a surface of which temperature is to be measured. A retra ...

Kenneth G Junkert, Henry P Voznick: Noncontact temperature measuring device. Wahl Instruments, Freilich Hornbaker Rosen & Fernandez, June 26, 1984: US04456390 (44 worldwide citation)

A portable, battery operated noncontact temperature measuring device including a lens for collecting infrared radiation and a thermopile for producing a signal indicative of the intensity thereof. The thermopile signal is amplified, linearized and summed with an ambient temperature signal derived fr ...

Henry P Voznick: Multiple probe temperature measuring system and probes therefor. Wahl Instruments, Gausewitz Carr Rothenberg & Edwards, March 13, 1984: US04436438 (25 worldwide citation)

The platinum resistive sensor of a temperature measuring surface probe has a resistance greater than the resistance to which the associated meter is calibrated. This provides a compensation that is a function of temperature and decreases errors due to heat loss from the probe. An immersion probe hav ...

Kenneth G Junkert, Henry P Voznick: Method and apparatus for measuring temperature. William Wahl Corporation, Causewitz Carr & Rothenberg, September 27, 1977: US04050309 (9 worldwide citation)

Temperature dependent and reference time intervals are simultaneously generated and differentially combined to provide a temperature signal that is employed to generate a probe linearization signal for combination with the temperature signal and digital display. A low resistance platinum probe carri ...
