Abstract:
One embodiment of the present invention is a system for identifying a human being from movement of the human being. The system includes a dual element pyroelectric detector, a Fresnel lens array, and a processor. The dual element pyroelectric detector detects radiation from the human being as the human being moves over time. The Fresnel lens array is located between the dual element pyroelectric detector and the human being. The Fresnel lens array improves collection efficiency and spatial resolution of the dual element pyroelectric detector. The Fresnel lens array includes a mask. The mask provides at least one zone of visibility. The processor is coupled to the dual element pyroelectric detector, the processor converts the detected radiation to a spectral radiation signature. The processor compares the spectral radiation signature to at least a second spectral radiation signature to identify the human being.
Abstract:
A remote or contact measurement thermometer, in particular an infrared thermometer, comprises an enclosure presenting a measurement portion by which a patient's body temperature is measured, and a display portion through which said temperature can be read. The enclosure is rigid with a case movable relative thereto about an axis of rotation passing through said enclosure, said case being able to assume two working positions relative to said enclosure (2), in a first of these positions said measurement portion (3) being external to the case (26) and in the second of which this latter covers the portion (3), said case (26) presenting an aperture (30) through which the display portion (4) can be accessed visually when said case is in its first working position.
Abstract:
A spark detector lens assembly is adapted to block energy from static electric discharges. The lens assembly includes a housing which receives a lens. The lens is adapted to pass infrared frequency energy therethrough. A conductive coating is disposed on one side of said lens, which is effective to block radio frequency energy but pass infrared frequency energy. The conductive coating may be electrically connected to an electrical ground path. The lens assembly is especially effective for preventing false alarms by shielding a spark detector from radio frequency energy radiated by static electric discharges.
Abstract:
A forehead skin or other body surface skin thermometer (1) has an infrared sensor (11) located in the thermometer probe front for viewing and detecting the infrared radiation heat at a body site, e.g. of the body forehead centre area skin for the other body surface skin. Concurrent operating ambient or sensor operating temperature are also measured. The above measured forehead skin temperature or the other body surface skin temperature is used as a reference base. The above concurrently sensed sensor operating or ambient temperature is used as an index so as to access corresponding temperature of a first body site such as the oral, rectal or axillar temperature. A final temperature reading display is determined from a lookup table built inside a non-volatile memory (41). The lookup table stored in the non-volatile memory (41) comprises three groups of the temperature database derived from a comprehensive clinical test result done previously with a substantial number of measuring targets. The groups composed are a second body site, temperature database, a concurrent operating ambient or sensor operating temperature database, and a corresponding first body site temperature database. Since this lookup table data is based on the substantial numbers of the clinical tests for the above three groups temperature database, this thermometer is a clinical test oriented thermometer design, which provides user with an accurate and reliable measuring result.
Abstract:
The thread engagement verifier system provides for verifying the quality of a threaded connection 12 between upper and lower for tubular member 16, 18. One or more thermal radiation sensors 14 are used in combination with a data acquisition and processing computer 20 and an output device, such as a video display 12. The thermal radiation is generated by sliding friction between the tubular members, and the sensors 14 sense radiation at a plurality of external locations and output heat intensity signals to the computer 20. Torque may also be sensed via a sensor 32 and input to the computer 20.
Abstract:
A centrifugal evaporator is described comprising a chamber in which sample containers are carried and rotated by a rotor and are pivotally mounted so as to swing up into a horizontal attitude as the rotor rotates. The evaporator includes an infra red source to direct infra red radiation towards the rotor and the sample containers carried thereon, to heat at least the latter and any sample material therein. A non-contact temperature sensing infra red pyrometer having a sensor with a defined field of view is mounted in the chamber, such that while the rotor as such is substantially out of its field of view, each sample container at least partly occupies the pyrometer field of view for a part of each rotation of the rotor. The positions of the infrared source and the pyrometer components are selected so that the radiation from the infra red source does not impinge on the pyrometer sensor.

Abstract:
The present invention concerns a method and an apparatus for measuring human or animal physiological core temperature based on detecting a thermal radiation signal emitted from an eye. The signal is filtrated removing a signal contribution from the vascular media of the eye providing a near infrared radiation signal from the retina. The human physiological core temperature is estimated by comparing the near infrared radiation signal with at least one reference signal in Fourier space, where each reference signal representing said near infrared part of a radiation spectrum from a black body having a certain known temperature. This temperature represents the temperature on the retina.
Abstract:
A code is deposited on an underside of a ceramic product, such as a tile (90), prior to firing of the product, such that the code is optically readable when the product is fired. A manufacturing facility is provided, comprising means such as a press (26) for forming granular ceramic material into a formed, pre-fired "green" product, means such as a printer (25) for applying an optically-readable heat-resistant code to an underside of the product and a kiln (34) for firing the green product.
