This arcane treatise deserves a second look by anyone interested in threaded languages, compiler construction,

This year he extends the HNSFE with a related capability: emulation of the effects of therapeutic and non-therapeutic drug use. The opioid narcotic drug model was chosen because of its importance in medicine and because of its potential for misuse. For this research the author utilized a frequency-to-voltage converter (FVC) as an analog calculational element to simulate the effects of drug binding to neural cell membrane receptors. The resulting voltages are utilized in this human narcotic use emulator (HNUE) to represent the level of opioid drug activity at the cellular level which initiates high level somatic and behavioral responses in the HNSFE artificial intelligence system. The HNUE is compatible with the computerized postoperative pain / narcotic dosing model of Liu and Northrop. Some effects of long-term drug use (the development of tolerance, physical and psychological dependence, addiction and the withdrawal syndrome) are emulated.

The author describes the use of linear circuitry in two areas of biological simulation: artificial neural networks and affective computing. The operational amplifier, with the assistance of some new analog chips and simple digital microcontrollers, is featured prominently in these linear designs.

Reviving a medical wearable computer for teaching purposes

This device was targeted for use by health-conscious consumers and other early adopters. Its expandable functions included weight management, blood pressure control, diabetes care, medication reminders, smoking cessation, pediatric growth and development, simple medical database, digital communication with a doctors office and emergency alert system. Various physiological sensors could be plugged-into the calculator-sized chassis. The device was shown to investor groups but funding was not obtained; by 1992 the author ceased pursuing it. The Computing and Mathematics Chair at a local University, a NASA acquaintance, approached the author to mentor a CS capstone course for Summer 2012. With the authors guidance, five students proceeded to convert this medical wearable computer design to an iPhone-based implementation using the Apple Xcode Developer Kit and other utilitie...

Manned deep space missions, beyond the Moons orbit, are being planned in this post-Shuttle era. The spacecraft required for longer flights will have relatively restricted crew interior volume. To decrease the negative impact of these tight quarters, the author has proposed recruiting smaller astronauts (abbreviated SAs), persons about one-half the height of current near-Earth crewmembers. This includes achondroplastic dwarfs, lower extremity amputees and persons with certain height-reducing birth defects such as phocomelia. To overcome issues of physical competence, strength and mobility of SAs, the author describes using advanced cybernetic prostheses for those with limb amputations or deformities, and motorized exoskeletons for the others. Muscle and bone-sparing space exercise programs for SAs should be simpler. For example, a motorized exoskeleton used for routine duties in space would also p...

Hacking medical devices a review - biomed 2013

This intrusion may lead to compromise of confidential patient data or loss of control of the device itself, which may be deadly. Risks to health from unauthorized access is in addition to hazards from faulty (buggy) software or circuitry. Historically, this aspect of medical device design has been underemphasized by both manufacturers and regulatory bodies until recently. However, an insulin pump was employed as a murder weapon in 2001 and successful hacking of an implantable defibrillator was demonstrated in 2008. To remedy these problems, professional groups have announced a variety of design standards and the governmental agencies of several countries have enacted device regulations. In turn, manufacturers have developed new software pr...

Multi-system fibromyalgia syndrome emulator - biomed 2009

Fibromyalgia Syndrome is a chronic disorder characterized by abnormal pain, fatigue, depression, ... more Fibromyalgia Syndrome is a chronic disorder characterized by abnormal pain, fatigue, depression, cognitive dysfunction and sleep disturbance. The body's immune, hormonal, and nervous systems are involved. The author proposes a model from his clinical practice where a relapsing human Herpesvirus 4 infection of ss-lymphocytes causes inappropriate activation of immune system components, thus leading to typical FMS signs and symptoms. This clinical model was subsequently embodied in a computer based on the author's human nervous system function emulator, which imitates the brain's biochemicalneural-cognitive operations. This Forth language emulator program runs on a multiprocessor network recently enhanced with 8-core 32-bit CPUs. Supplemental analog circuit boards provide support for an artificial neural network, synthetic emotion and cellular substrate-receptor binding activity simulation. The effects of antiviral antibiotics and other chemicals on this disease are include...

These user-programmable "nanocontrollers", some with as few as eight pins, now include a variety of linear on-chip components. Miniscule complex mixed digital and analog systems are now possible. This paper outlines some of these advances, then describes how using these new microcontroller features to create a better artificial neuron have improved the author's ten-year-old neural network design.

This paper discusses two kinds of computer-to-human interaction techniques which involve computerizea facial gestures: the first is the graphics representation of the human face projected on a video display; the second is the physical embodiment of facial expressions using an android robot. These simulated facial gestures may be accompanied by computerized speech synthesis, voice recognition capability or machine vision for recognition of the facial expressions of the human viewer. The author reviews both major techniques, then discusses current and proposed applications of this methodology.
