| PURPOSE:To measure the direction of the surface polarization in a pyroelectric material in a non-destructive and handy manner by varying the temperature of a pyroelectric material so that a microprobe of a voltage detector will approach the vicinity of the surface thereof to check changes in the potential. CONSTITUTION:The single crystal of a pyroelectric material such as lithium tantalate produced by a poling treatment (single polarization by applying a voltage above the Curie temperature) is cut out to the thickness of 1mm. to form a sample. This sample is placed on a hot plate of 150 deg.C through a metal plate and then, as a spherical aluminum probe connected to a leaf electrometer approaches it, a foil opens therebyenabling the observation on how an electric charge will be formed. | ||||||

The movement or a change in the property of the cantilevered probe can occur, for example, by adsorption of the target material, desorption of the target material, reaction of the target material and/or phase change of the target material. Examples of detectable movements and properties include temperature shifts, impedance shifts, and resonant frequency shifts of the cantilevered probe. The overall chemical detection system can be incorporated, for example, into a handheld explosive material detection system. | ||||||

| A system and method for detecting an anode pressure sensor failure in a fuel cell system. The system and method include a controller that sets an initial minimum anode pressure sensor value and an initial maximum anode pressure sensor value. The controller determines a desired time interval for sampling anode pressure measurements and determines a total number of samples of anode pressure measurements to be collected by the controller from an anode pressure sensor. The controller also compares a pressure difference between the initial or a measured minimum anode pressure and the initial or a measured maximum anode pressure to a predetermined pressure difference threshold and sets a pressure sensor fault if the pressure difference between the initial or measured minimum anode pressure and the initial or maximum anode pressure is less than the predetermined pressure difference threshold. | ||||||

| A method of and apparatus for examining substances by subjecting them to a gravitational field while measuring the electrical effect derived from any resulting charge orientation. A centrifuge is preferably employed to give high g forces and an electrode system is used to provide an output signal. The output signal can be plotted against changing g forces to give a gravitational spectrum analysis graph. An apparatus for using such method is also described. Said apparatus comprises a direct or capacitive electrode system with one or more electrodes made of noble metal. | ||||||
