	Nanocaps help scientists control magnetism reversal
		In this case, the scientists applied a reverse magnetic field to the already magnetized nanocaps, and then analyzed how the magnetization reversal evolved in individual caps.
		Previous theories used to describe flat film layers don’t describe the magnetism reversal for the different cases of curved film.
		Because the scientists have control over the film curvature – and subsequently over anisotropies and magnetic properties – the discovery has opened up doors to the possibilities of tailoring magnetism reversal for new nanoscale applications.

	Device for controlling reversal points of a reciprocating machining member - Patent 4504917
		Control circuit 5 also includes a monitoring or supervising circuit 24 in part for disabling compensating circuits 9 and 9a upon detecting an error in the lower and upper reversal points manually selected via potentiometers 2 and 3.
		Should the actual reversal point at the lower end of the tool carrier's stroke path coincide with preselected lower reversal point, the difference signal at the output of rectifier 13 will be of zero voltage, the sum of the preceding difference or error signals being transferred from memory 16 through added 14 to memory 15.
		A stroke length control circuit 5 according to the present invention is provided with means for automatically increasing (or decreasing) the distance between the selected lower reversal point and the initial lower reversal point in accordance with increasing (or decreasing) stroke length of carrier 55 as determined by the setting of potentiometers 2 and 3.

	841. Mineral oils and waxes (WHO Food Additives Series 35)
		In the reversal study (dosed at the 2% level only), food intake was increased in all male groups, including the HSW group, throughout the study.
		Livers of female rats in the control and 2% dose groups from the main and reversal studies (excluding the coconut oil group) were subsequently analyzed for content of hydrocarbons of different chain length.
		A reversal period of 1 year should also be included, in order to determine whether the granulomatous hepatic lesions observed in rats in the 90-day studies are fully reversible.

	Variable resolution control system - Patent 4782285
		In accordance with the method and apparatus of the present invention, the output of a given control device, such as a potentiometer having a given range of adjustment, is converted to an output having an effectively larger range of adjustment having greater resolution beyond the capability of the original control range.
		If the input control device is not continuously variable but has stops, a detection is made when the remaining adjustment in the control device is insufficient to cover the range of output remaining of the predetermined number of output steps produced by the processor.
		If control device 10 has a limited range of movement, a point will be reached such that the operator will be approaching the end limit of the control device faster than the output of D/A converter 16 is approaching the end of its total of 4,096 steps in the given example.

	Rolling ring linear drive & actuator for reciprocating linear motion - Amacoil
		Using the same lever attached to the reversal mechanism, the end stops may be slightly re-configured to make the RG linear drive decelerate to a point where the drive dwells until the reversal a mechanism is actuated.
		By the time the linear drive reaches the end stop, and the reversal mechanism is fully flipped, linear speed is almost zero because the V-Cam has rotated the reversal mechanism to the point where the rolling ring assembly is almost at its zero pitch position.
		Fine tuning of the linear drive's reversal points is possible simply by turning the control knobs until the end stops move to the desired position.

	The Reversal Procedure
		Each year, a number of men elect to have a reversal of their vasectomy, often because of a change in their lives, such as having a new spouse through remarriage, and the desire for a second family, or a change in family planning goals within the same marriage.
		The reversal procedure is performed for about 50,000 men each year; a number that is growing with the more widespread availability of the procedure, reduced cost factors, and the training and experience of more surgeons who perform it.
		A vasectomy reversal is considered to be comparatively safe, but it is a more delicate and involved microsurgical procedure than a vasectomy.

	Reversing Birth Control: Getting a Vasectomy Reversal (Site not responding. Last check: 2007-10-21)
		A vasectomy reversal is a surgical procedure used to reverse the effects of a vasectomy.
		Men who have reversals within three years of their original vasectomy are much more likely to have sperm mix with their ejaculate again.
		Unfortunately, the cost of a vasectomy reversal tends to be quite high and these surgeries aren’t generally covered by insurance.

	REVERSAL FILM
		Reversal film was engineered as a one-step, cost effective system that originates much as a slide in still photography (identical film).
		After developing, the images are ready for immediate screening and is usually a one-of-a-kind reel of film that should be carefully protected as if it were a negative.
		Reversal was popular because the cost of a print was not necessary but the down side of reversal is that it's a little tricky to process and few labs develop it anymore.

	Inside-Out Displays
		For reasons given in Chapter 3, it was thought that foreground occlusions might reduce this problem, resulting in a performance measure for the foreground occlusion effect.
		Despite the congruence between inside-out displays and the view out the window of the cockpit, inside-out displays are prone to a misinterpretation known as a ``control reversal''.
		When a control reversal occurs, the pilot inadvertently attempts to control the representation of the ground, rather than of the plane.

	More About Aircraft Attitude and Steering Displays
		All pilots do learn to control flight attitude by reference to the artificial horizon, and by the time they qualify for an instrument rating they have long since learned the correct responses to the display's indications.
		In addition to responding immediately to control inputs, changes in flight path direction were indicated by having the airplane symbol move laterally from the display center parallel to the horizon in proportion to the rate of turn.
		An unaugmented pictorial display that served as a control condition presented a simplified view of an airport scene that was responsive to the changing attitude and flight path of the simulated airplane.

	The Wright Brothers \| Perfecting the Control System
		The new fixed vertical rudder seemed to cure the control reversal problem they experienced in 1901—at least most of the time.
		To solve the control reversal problem, the Wrights made the rudder movable, so its position could be coordinated with the wing-warping.
		They connected the rudder control cables to the wing-warping hip cradle, so a single motion by the pilot operated both controls.

	Birth Control - Birth Control - Vasectomy Reversal — 5 Things You Need To Know
		During the original vasectomy the vas deferens — the tube which carries sperm from the epididymis to the prostate — is cut and clamped.
		A vasectomy reversal involves removing the clamps and stitching the vas deferens together again, (or in a minority of cases actually attaching the vas deferens to the epididymis — a procedure known as a vasoepididymostomy) thereby allowing the flow of sperm once more.2.
		However the current level of technological advances in microsurgery means that as many as 97% of men who undergo a straightforward vasectomy reversal experience a return to normal sperm counts and 50% of cases resulted in pregnancy.
