Force feedback teleoperation with physiological motion compensation
IFAC Proceedings Volumes, 2009Abstract In medical and surgical robotized applications one of the most recurrent problems is the physiological motion of the patient. Specifically, respiratory motion can have a large amplitude and thus prevent accurate gestures. So, for a robot which interacts with a patient, it is obvious that being able to compensate physiological motion would be ...

Distortion Compensating, Condenser-Earphone Driver for Physiological Studies
The Journal of the Acoustical Society of America, 1968A design for a condenser earphone driver is given. The driver predistorts electrical input signals to counteract the inherent square-law operation of the condenser earphone. Thus, smaller-diameter earphones, with their wider bandwidth characteristics, can be used at stimulus levels of interest without appreciable harmonic distortion.

Towards physiological motion compensation for flexible needle interventions
2015 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2015Flexible bevel-tipped needle steering has been an active research topic since the last decade. However, most of the work presented so far performs flexible needle steering in static phantoms or non-static virtual environments. The insertion of flexible bevel-tipped needles into soft-tissue subjected to motion disturbances is still an open research ...

Physiological compensation in unilateral eyestalk ablated crayfish, Cherax quadricarinatus
Journal of Experimental Zoology, 2001The eyestalks of crustaceans contain neurosecretory cells involved in the regulation of molting. In crayfish, bilateral ablation results in increased molting frequency and weight gain whereas unilateral ablation typically has no effect on molting frequency and weight gain.

A novel control architecture for physiological tremor compensation in teleoperated systems
The International Journal of Medical Robotics and Computer Assisted Surgery, 2012AbstractBackgroundTelesurgery delivers surgical care to a ‘remote’ patient by means of robotic manipulators. When accurate positioning of the surgeon's tool is required, as in microsurgery, physiological tremor causes unwanted imprecision during a surgical operation.

Vestibular Compensation:Physiological und Clinical Aspects
Acta Oto-Laryngologica, 1983Vestibular compensation is achieved by means of a multisensory substitution process. Experimental and clinical observations indicate that patients, suffering from a sudden loss of vestibular function, should get an early multisensory training in order to induce adaptive changes as soon as possible.

Neurocomputing, 2001
Abstract In a typical neurophysiological recording, the shape of the voltage trace due to an action potential depends, among other things, on the mutual geometry of the tissue and the electrode, and on the overall health of the preparation. These parameters change throughout the duration of the experiment, typically continuously and slowly, with ...

Physiological Compensation for Toxic Actions of Organophosphate Insecticides
1989The neurochemical changes which could serve as physiological compensatory mechanisms during recovery from a high level acute intoxication with an organophosphate anticholinesterase were studied concurrently with behavioral deficits resulting from the intoxication.

Theory, simulation, and compensation of physiological motion artifacts in functional MRI
Proceedings of 1st International Conference on Image Processing, 2002Mapping the location of brain activity is a new and exciting application of magnetic resonance imaging (MRI). This application area has already seen the use of a variety of magnetic resonance image acquisition methods, including spin-warp, spiral k-space, and echo-planar imaging, each of which has its own advantages and disadvantages.

Intrauterine asphyxia and the breakdown of physiologic circulatory compensation in fetal sheep
American Journal of Obstetrics and Gynecology, 1990In response to acute hypoxemia, the fetus invokes physiologic compensatory mechanisms that cause a preferential redistribution of the circulation to sustain the brain, heart, and adrenal gland and maintain blood flow to the placenta. These mechanisms are available for a limited time and eventually the fetus is no longer able to maintain preferential ...
