Pulse transducer with artifact signal attenuator

An artifact signal attenuator for a pulse rate sensor is described. The circuit for attenuating background noise signals is connected with a pulse rate transducer which has a light source and a detector for light reflected from blood vessels of a living body. The heart signal provided consists of a modulated dc signal voltage indicative of pulse rate. The artifact signal resulting from light reflected from the skin of the body comprises both a constant dc signal voltage and a modulated dc signal voltage. The amplitude of the artifact signal is greater and the frequency less than that of the heart signal. The signal attenuator circuit includes an operational amplifier for canceling the artifact signal from the output signal of the transducer and has the capability of meeting packaging requirements for wrist-watch-size packages

Condition sensor system and method

The condition sensor system comprises a condition detector which produces a pulse when a parameter of the monitored condition exceeds a desired threshold. A resettable condition counter counts each pulse. A resettable timer is preset to produce a particular time frame. The counter produces a condition signal when the accumulated number of pulses within the time frame is equal to or greater than a preset count. Control means responsive to the incoming pulses and to the condition signal produce control signals that control utilization devices. After a suitable delay, the last detected pulse simultaneously resets the pulse counter and the timer, and prepares them for sensing another condition occurrence within the time frame. The invention has particular utility in the process of detecting rocking motions of blind people. A controlled, audible, bio-feedback signal is provided which constitutes a warning to the blind person that he is rocking

Cardiovascular instrumentation for spaceflight

The observation mechanisms dealing with pressure, flow, morphology, temperature, etc. are discussed. The approach taken in the performance of this study was to (1) review ground and space-flight data on cardiovascular function, including earlier related ground-based and space-flight animal studies, Mercury, Gemini, Apollo, Skylab, and recent bed-rest studies, (2) review cardiovascular measurement parameters required to assess individual performance and physiological alternations during space flight, (3) perform an instrumentation survey including a literature search as well as personal contact with the applicable investigators, (4) assess instrumentation applicability with respect to the established criteria, and (5) recommend future research and development activity. It is concluded that, for the most part, the required instrumentation technology is available but that mission-peculiar criteria will require modifications to adapt the applicable instrumentation to a space-flight configuration

Zoogeography, ecology, and systematics of the genus Rhagovelia Mayr (Heteroptera: Veliidae) in Borneo, Celebes, and the Moluccas

The genus Rhagovelia is revised for the region comprising Borneo, Celebes, and the Moluccas. Redescriptions are given for species previously described from the area, and 26 new species are described. Figures of the dorsal habitus and key characters are provided for all species, accompanied by a key to species and distribution maps. Species occurring in the region are divided into eight monophyletic intrageneric species groups, some of which also contain members outside the region, based primarily on wing venation, thoracic morphology, and genitalia. A zoogeographic analysis is presented based on the distribution of these groups within the Malay Archipelago and surrounding regions. We conclude that the present Rhagovelia fauna of the Malay Archipelago is derived from species which originated in continental Southeast Asia, Australia, and New Caledonia. Distinct lineages have entered the region from each of these three source areas, penetrating the archipelago with differing degrees of success and contributing to the fauna of each individual island to varying extents. Species groups of Asian origin do not extend beyond Celebes and the Lesser Sunda islands, while species groups of Papuan origin are absent in the Lesser Sundas and do not extend west of Borneo. Endemic species groups have also arisen on New Guinea, the Philippines, the north Moluccas, and Borneo. A section on ecology and behavior is provided, dealing in particular with the altitudinal segregation of species on individual islands. The following new Rhagovelia species are described: bacanensis, borneensis, celebensis, christenseni, grayi, hamdjahi, incognita, lorelinduana, meikdelyi, melanopsis, minahasa, obi, pruinosa, ranau, sabela, samardaca, samarinda, sarawakensis, silau, simulata, sondaica, sulawesiana, tawau, lebakang, unica, and wallacei. Rhagovelia mindanaoensis Hungerford and Matsuda 1961 is synonymized with Rhagovelia orientalis Lundblad 1937 (new synonymy)

The scientific publications of Roland Fountain Hussey : 1916 - 1968

R. F. Hussey was born in San Francisco, California 16 November 1896 and died 19 August 1968 in Gainesville, Florida. He held academic positions at New York University, Florida Southern College and the University of Florida, and was to have been retired from the latter as their first Professor Emeritus of Biology. For about twenty years following 1926 he held administrative positions in the New York Academy of Medicine and Doctors Hospital and during this time he published little except the excellent catalog of Pyrrhocoridae (which at that time included the family Largidae) as fascicle 3 of the General Catalogue of Hemiptera. This was his most significant contribution to Hemipterology. He envisioned and collected some materials for the catalogue of Heteroptera of North America, a work carried forward by J. L. Herring and finally brought to fruition in 1988 by editors T. J. Henry and R. C. Froeschner

Application of advanced technology to space automation

Automated operations in space provide the key to optimized mission design and data acquisition at minimum cost for the future. The results of this study strongly accentuate this statement and should provide further incentive for immediate development of specific automtion technology as defined herein. Essential automation technology requirements were identified for future programs. The study was undertaken to address the future role of automation in the space program, the potential benefits to be derived, and the technology efforts that should be directed toward obtaining these benefits

Saldolepta kistnerorum, new genus and new species from Ecuador (Hemiptera, Leptopodomorpha), the sister group of Leptosalda chiapensis. American Museum novitates ; no. 2698

5 p. : ill. ; 26 cm.Includes bibliographical references (p. 5)."Saldolepta kistnerorum, new species, is described from the nest of Nasutitermes dendrophilus from the western lowlands of Ecuador. It is considered the sister group of Leptosalda chiapensis from Tertiary Chiapas amber, and as such is the first recent member of the Leptosaldinae. It is the first known apparent inquiline in the Leptopodomorpha"--P. [1]
