Termal-id: a Personal Identification Method Using Body Tempreture

We propose a novel personal identification method, named Thermal-ID, which utilizes human body temperature as a source of identifying information. Thermal-ID is expressed by the temperature difference generated by partially covering the surface of the body with thermal barrier material (e.g., cutout urethane foam-coated aluminum foil). The aim is to positively identify a subject with minimal di...

Ferrite-guided cyclotron-resonance maser.

The concept of a cyclotron-resonance maser (CRM) with a ferrite loading incorporated in its waveguide is proposed. The CRM interaction occurs between the rotating electron beam and the em wave propagating along a longitudinally magnetized ferrite medium. The ferrite anisotropic permeability resembles the CRM susceptibility in many aspects, and particularly in their similar response to the axial...

/ High Power Ferrite Phase Shifter

Theoretical estimates of phase shifter performance as a function of material parameters are presented by examining the results obtained from the small perturbation model used by Button and Lax and from the fully ierrite loaded, parallel plane waveguide model used by Suhl «And Walker. The extension of Suhi's theory on nonlinear effects at high power by Fletcher and Silence is applied to relate t...

Thick Film Ni-Ferrite Inductors

New Developments in Ferrite Plating

The ferrite plating a method synthesizing ferrite films from an aqueous solution -has developed lately as follows; (1) Applying power ultrasound to aqueous solution improves the qualities of ferrite coating on polymer microspheres much, (2) similarity is found between mechanisms of the ferrite plating and bacterial FesO4 ( magnetsome) synthesis, (3) using highly alkaline (pH=13) solution contai...
