Abstract: A method and system receives test requirements and test settings in order to design a test. An identifier is assigned to the test that was designed and the test is stored in a database using the identifier to identify the test. In addition, the test is printed on at least one sheet or form and a wireless read/write device is programmed with the identifier assigned to the test. The wireless read/write device is attached to the sheet on which the test was printed. Thus, the sheet and the wireless read/write device can be provided to a test operator to allow the test operator to wirelessly read the identifier from the wireless read/write device. Then, the test operator can access the test from the database based on the identifier read from the wireless read/write device. The test instructions (comprising the test requirements and test settings) are provided from the database to the operator to perform the test and potentially produce a physical test output.

Abstract: A process for preparing a ferrite in which a green body containing at least about 50 weight percent of iron compound is first sintered and then cooled. During the cooling cycle, from about 1,000 to about 700 degrees centigrade, the body is contacted with a reduced oxygen atmosphere containing less than 10 volume percent of oxygen. From 700 to 200 degrees centigrade, the reduced oxygen atmosphere contains less than 1 part per thousand of oxygen. Thereafter, the sintered body is treated to remove at least some sharp edges and to change its permeability; and it is then contacted with an etchant.

Abstract: A method and apparatus for establishing the magnetic permeability of a batch ferrites at a predetermined target permeability. Ferrite parts are sintered to achieve a magnetic permeability greater than the target permeability. The sintered parts are then tumbled to suppress the magnetic permeability below the target permeability. The parts are then exposed to a chemical wash to increase the magnetic permeability and continuously monitored to allow setting the magnetic permeability at the target permeability.
