The present invention comprises methods and apparatus for cancer detection involving the measurement of temporal periodic changes in blood perfusion associated with immune response, occurring in neoplastic lesions and their surrounding tissues. Particularly, the method for cancer detection involves the detection of non-neuronal thermoregulation of blood perfusion, aberrant modulation of blood perfusion, aberrant temperature oscillations associated with blood perfusion, aberrant thermoregulatory frequencies associated with blood perfusion, and periodic changes in the spatial homogeneity of skin temperature.

The present invention comprises methods and apparatus for assessment of the effects mental stress involving the measurement of periodic changes in skin perfusion. Using a remotely mounted infrared camera, dynamic area telethermometry (DAT) measures the autonomic nervous activity by monitoring and quantitatively analyzing the modulation of cutaneous perfusion. When people gets 'nervous' their sympathetics 'act up' and they blush (vasodilates) or becomes pale (vasoconstricts). A DAT test of the face proves to be a superior 'lie detector' test since emotional stress is reflected in an autonomic nervous response that can be measured remotely. DAT is much more sensitive than any visual assessment of skin color or than instrumental measurement of diaphoresis. Not only is it more reliable than currently used polygraph tests, but its non-contact administration is so simple and innocuous that it could be done without the subject's awareness. Furthermore, the same device can be used to meet the needs of a variety of psychiatric and psychological evaluation problems, including depression, drug addiction and dementia, as well as psychological learning disabilities.

Method and apparatus for the pollution-free generation of electrical power from hydrogen in which molten lead is electrochemically oxidized to produce lead oxide and electricity in a single cell in which the resulting lead oxide is simultaneously converted back to lead metal by thermochemical reduction with hydrogen fuel, the entire process being carried out in a single cell using a molten salt as electrolyte in a temperature range of 500.degree. to 900.degree. C. The entire cycle consumes only hydrogen and oxygen, while producing electricity.

A method and means of making an immunological assay is provided whereby stable isotopes of certain elements, or long-lived radioisotopes of these elements are used to tag antigens or antibodies. A known amount of the tagged antibodies or antigens are then mixed with the unknown number of antigens or antibodies forming an antigen-antibody complex, (bound) and free tagged antigens, or antibodies, (unbound). The bound antigens or antibodies are separated from the unbound, and their quantity is determined by negative ion mass spectrometry. An aliquot of the unbound or bound antigens or antibodies is taken and dried in a metal crucible, for example, which is then inserted into a negative ion mass spectrometer where the sample is vaporized, ionized and the number of tagging atoms is then counted. From the information provided by the count, an immunoassay can be established.

Method and apparatus for the pollution-free generation of electrical power from carbonaceous fuels in which molten lead is electrochemically oxidized to produce lead oxide and electricity in a single integrated cell in which the resulting lead oxide is simultaneously converted back to lead metal by carbothermic reduction with a carbonaceous fuel, the entire process being carried out in a single cell using a molten carbonate as electrolyte in a temperature range of 500.degree. to 900.degree. C. The entire cycle thus consumes only carbon and oxygen and produces electricity. It is found that by thus coupling the electrochemical cell and the thermochemical regeneration system, the resulting integrated carbon-lead-air cell will maintain a voltage well above that provided by a simple lead-air cell approaching that of a hypothetical carbon-air cell.
