| Number | Title | Issue Date |
| 6949286 | Radiation-absorbing layers for thermopile radiation detectors A radiation-absorbing layer for a thermopile radiation detector highly absorbs incident radiation within a predetermined band of wavelengths. The layer comprises a solid construction of a mixture of an oxide of silicon and separate and/or linked particles of at leas... | 09/27/2005 |
| 4786335 | Infra-red detector A novel multilayer photoconductive I.R. detector is formed by incorporating alternate p and n-type layers, such that many layers occupy the detector thickness. The detector may be considered as a n-type photoconductor containing buried isolated p-type reg... | 11/22/1988 |
| 4778770 | Process for making sensor elements in a retaining frame for a pyrodetector A sensor element arrangement for a pyrodetector has a concave mirror with a sensor element arranged at a focus of the concave mirror and further sensor elements arranged laterally therefrom. Electrodes of both polarities are present on each side of the fi... | 10/18/1988 |
| 4665276 | Thermoelectric sensor This invention concerns a thermoelectric sensor of the air-backed type comprising a thin-film thermopile with a receiving area of approximately 1 mm2 under a protective atmosphere of atmospheric pressure. To increase the responsivity of such se... | 05/12/1987 |
| 4250384 | Radiant energy systems, memories and thermal imaging methods and apparatus A very thin insulator having a dipole structure such as a dielectric material having ferroelectric properties and, preferably, also having thermodielectric properties, is used as the insulator insulating an electrode of an electrode pair from a semiconduc... | 02/10/1981 |
| 4111717 | Small-size high-performance radiation thermopile A thermopile type radiation detector for use in radiation pyrometry having small size and high performance in which the thermopiles are formed by evaporating the thermocouple leads onto a thin substrate together with a pattern distribution of thermocouple... | 09/05/1978 |
| 4102196 | Heat sensor A non-contact sensor for observing, recording or responding to the temperature of a hot moving or stationary slender target, such as a wire, wherein a plurality of sensor units, each including a multiplicity of thermocouples, are mounted in arcuate format... | 07/25/1978 |
| 4002499 | Radiant energy collector An electromagnetic energy collection device is provided which does not require a solar tracking capability. It includes an energy receiver positioned between two side walls which reflect substantially all incident energy received over a predetermined incl... | 01/11/1977 |
