Floppy diskette security measures

Information security — a broader term than computer security — encompasses the safeguarding of information wherever it resides and whatever form it takes. Information security accordingly includes consideration of information residing in file cabinets, voice communications networks, and other places outside computers. It additionally includes consideration of information typewritten on paper, in diagrams, and in other forms that may not be computer controlled. Floppy diskettes are, in many people's eyes, outside the computer security area, and accordingly frequently ignored. Nonetheless, these diskettes often contain sensitive and/or critical information. This paper discusses practical policies, procedures, and technical controls that can be used to appropriately safeguard information resident on floppy diskettes.

Human Pulse Diagnosis for Medical Assessments Using a Wearable Piezoelectret Sensing System

Real‐time and continuous monitoring of physiological signals is essential for mobile health, which is becoming a popular tool for efficient and convenient medical services. Here, an active pulse sensing system that can detect the weak vibration patterns of the human radial artery is constructed with a sandwich‐structure piezoelectret that has high equivalent piezoelectricity. The high precision and stability of the system result in possible medical assessment applications, including the capability to identify common heart problems (such as arrhythmia); the feasibility to conduct pulse palpation measurements similar to well‐trained doctors in Traditional Chinese Medicine; and the possibility to measure and read blood pressure.

A comparison of techniques for the metallographic preparation of thermal sprayed samples

Metallographic preparation of thermal spray coated samples is often difficult because hard and soft materials, which normally require different polishing techniques, are commonly present in a single spraycoated sample. In addition, the microstructures of many spray- deposited materials make them prone to pull-out damage during cutting, grinding, and polishing operations. This study compares alternative metallographic techniques to prepare three common types of thermal sprayed coatings: (1) a plasma sprayed alumina-titania wear coating, (2) a plasma sprayed zirconia thermal barrier coating, and (3) a high-velocity oxy-fuel (HVOF) sprayed tungsten- carbide/cobalt (WC/Co) hard coating. Each coating was deposited onto a steel substrate and was prepared with metallographic protocols based on silicon carbide (SiC) papers, bonded diamond platens, and diamond slurries. Polishing with SiC papers generally produced edge rounding and significant pull- out, which increased the apparent porosity of the coatings. Polishing with bonded diamond platens produced less edge rounding, but some pull- out was still observed. Preparation by diamond slurry lapping consistently produced the best overall results. Porosity artifacts produced by polishing with SiC papers and bonded diamond platens also resulted in spuriously low hardness values for the WC/Co samples; however, hardness results for the two ceramic coatings were not affected by the polishing method.
