Bicycle: Propel Adaptive Cycling Pedal

Image
Propel Adaptive Cycling Pedal I have multiple sclerosis. The disease inflicts neurological trauma and causes nerve-muscule fatigue. An MS attack will limit nerve conduction and in turn, limit muscle to-from engagement.  Nerve fiber conduction has the same four conduction conditions, normal, resistive, open, and shorts as wired circuits.  Open and shorted nerve fibers can exhibit a permanent disability. However, the brian's neuroplasticity can develop adaptive circuits. The Propel pedal began as an adaptive device as a workaround for my MS disability challenges to pedal the trike.  However, the research and development to make the adaptive pedal discovered a new pedaling performance and methodology for all cyclists.  I am a USMC veteran, 68-71.  When an MS release prevented me from doing an upright bike mount, I petitioned the VA's Adaptive Sports Program for a recumbent trike. Before the VA would approve the trike purchase, I had to prove I could ride the trik...

Veteran: 38.1725 ~ Information Model

Image
Veterans' Benefit 38 USC 1725  Statues as an Information Model 38 USC 1725 is the Law about business relationships with veterans, DVA, community providers, private insurance, and others. This information model describes the business relationships. Technical Background Dictionary: An information model in software engineering is a representation of concepts and the relationships, constraints, rules, and operations to specify data semantics for a chosen domain of discourse. Typically, it specifies relations between kinds of things, but may also include relations with individual things. It can provide a sharable, stable, and organized structure of information requirements or knowledge for the domain context. Ontology Models – Formal structures (classification systems, assemblies, and parts, language) Affinity Models – Abstract structures (diagnostic, association, disassociation, discrimination, acceptance)   Social Models – Tribe structures (law, group dynamics, ...

Engineering: The Interloper Phenomena

The Interloper P henomena This is a computer folklore story I heard many years ago. The story illustrated the essence of technology security. I do not know how the actual story’s facts, however, the story can be told with different facts; however, the essence and outcome would be the same.  In the mid-1970s, Wang was a company in Massachusetts who fostered a computer-based word processing system. Boston legal companies hired armies of legal secretaries. The secretaries would type pages and pages of legal documents flawlessly without errors. Most legal contracts required multiple original documents for signatures. The effort required to constantly key typewriters quickly and accurately could take years to be highly skilled. A typical large law firm could have dozens of legal secretaries.  Wang’s marketing to the law firm was a simple business proposal. A Wang word processing system can replace many legal secretaries. The cost and the return made eliminating lega...
