Abstract: A Barkhausen probe includes a magnetizing field generator, a magnetoresistive magnetic field sensor, a direct current power supply for biasing the magnetoresistive magnetic field sensor and signal conditioning electronics. The Barkhausen probe is capable of generating and sensing the Barkhausen noise emanating from the surface of a cyclic magnetized specimen. The conditioned Barkhausen noise output of the signal conditioning electronics is usable as input to various analysis systems where textural analysis of the material can be performed.

Abstract: A protective sleeve assembly for preventing damage to a power cord providing alternating voltage and current to an electric cutting implement during the inadvertent contact between the edge of the blade assembly of the cutting implement and the power cord is invented. The protective sleeve assembly comprising: a through-wall slit that extends longitudinally the full length of the protective sleeve assembly where the though-wall slit allows for easy insertion of the power cord into the interior of the sleeve assembly; support surfaces at opposing edges of the through-wall slit which extends the length of the slit that provides for compressive interference between the opposing edges of the slit; and, a method of attaching the first end of the protective sleeve assembly to the alternating current carrying power cord connected to the electric cutting implement.
