Rough estimates are given of thermodynamic limitations on stability and bit storage density and observations made on additional constraints self-replicative ability might entail. Reasonable storage stability requirement is bit configurational energy ≥20 kT (~0.5 ev or 10-12 erg) to prevent thermal degradation of information; significant diminution requires low temperature storage. Bit linear dimension is ~10 Å (much smaller goes below molecular size, much larger exceeds known bionic bit size), corresponding to storage density upper limit ~1021 bits/cc. Self-replication by diffusion of \"building blocks\" from solution and short-range chemical forces (e.g., template model) implies one-or two-dimensional structure by accessibility arguments; one dimensional favored over two dimensional to permit separation of copy and model via higher solution entropy of one dimensional. Static storage is more stable in three-dimensional packing via steric considerations, resonance stabilization, or internal H bonding. One thus expects a) three-dimensional bionic packing during inert storage, b) one-dimensional \"unrolled\" actively replicating form, c) rather close approach to ultimate storage density in inert form, d) higher configurational binding energy per bit for self-replicating systems than required for inert storage. These expectations seem to be reasonably well realized in nature.","PeriodicalId":199455,"journal":{"name":"IEEE Transactions on Military Electronics","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1963-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126190236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are two basic principles for achieving angular discrimination: 1) multiple detectors with different angular response characteristics and 2) a single detector which scans its response characteristic. Up to now only the multiple-detector approach has been applied to explain the phenomenon of color vision. This paper postulates that the eye employs the scanning discrimination principles to perceive color. A wavelength-dependent effect within the cone causes light of different wavelengths to produce different spatial distributions of energy in the photodetector region. An electrical process scans across this photodetector region producing a modulated waveform which defines the color information. The dc value of the waveform gives the white information, the first harmonic gives the blue-yellow information and the second harmonic gives the green-red information. The phase determines the difference between blue and yellow and between green and red The waveform is demodulated in the retina to generate separate dc voltages which produce the white-black, blue-yellow and greenred sensations.","PeriodicalId":199455,"journal":{"name":"IEEE Transactions on Military Electronics","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1963-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121486057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This tactile displayis being used to present spatial and temporal patterns to the skin to investigate the pattern recognition capabilities of the tactile sense. Airjet tactile stimulators were used in the experiments because they combine the fine localization property of poke-probe stimulators with the slight adaptation property of vibrators. Two perceptual phenomena that were investigated are apparent location and apparent motion. Apparent location occurs when two airjets of different pressure are sensed as one airjet located on the line connecting the two jets. Pressure difference and apparent location were found to be functionally related. This phenomena was extended to two dimensions with three noncollinear stimulators. Apparent motion occurs when two airjets with different onset times are sensed as one airjet moving between two locations. This phenomenon was found to occur when there was a 0.05-to 0.15-second time difference between the onsets of the two pulses, provided that the pulses overlap by less than 0.2 second. The system used to program the array of approximately 100 tactile stimulators is described.","PeriodicalId":199455,"journal":{"name":"IEEE Transactions on Military Electronics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1963-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133780527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
