A timed vital capacity recording device.
Since Gaensler’s article’ appeared in 1951, the value of the “Timed Vital Capacity” test has been eminently confirmed. With one test, the presence of both restrictive and obstructive ventilating defects is demonstrated. Here presented is a device that has been used for four years as the first step in the evaluation of lung function of all candidates considered for pulmonary surgery at the Glenn...
متن کاملThe "Conductor's Jacket": A Device for Recording Expressive Musical Gestures
We present the design and architecture for a device called the “Conductor’s Jacket,” which we built to collect and analyze data from conductors. This device is built into normal clothing and designed in such a way as to allow for normal activity and not encumber the movements of the wearer. The jacket records physiological and motion information from musicians in order to better understand how ...
متن کاملThe Effect of Adenosinetriphosphate upon Actomyosin Solutions, Studied with a Recording Dual Beam Light-scattering Photometer
A recording dual beam light-scattering photometer is described which permits kinetic studies involving changes in turbidity, and which is not, as are single photocell instruments, affected by the errors due to the attenuation of the scattered light within the turbid medium. With this method, a renewed study has been made of the physical changes occuring in actomyosin under the influence of ATP.
متن کاملDeveloping a Device for Automated Peritoneal Dialysis
Background: Peritoneal dialysis (PD) is an efficient alternative for hemodialysis. Removal of waste metabolites and excess water from the blood circulation are the two main tasks done during dialysis. These are done by using a filter; in PD, the naturally semi-permeable peritoneal membrane acts as the filter. Automated PD machines control intelligently the operations to enhance the efficiency a...
متن کاملA microfluidic device for dry sample preservation in remote settings.
This paper describes a microfluidic device for dry preservation of biological specimens at room temperature that incorporates chemical stabilization matrices. Long-term stabilization of samples is crucial for remote medical analysis, biosurveillance, and archiving, but the current paradigm for transporting remotely obtained samples relies on the costly "cold chain" to preserve analytes within b...
