Subject field(s)
  • Visual Disorders
CONT

Myopia, also known as nearsightedness, is a common refractive error that can be corrected with eyeglasses, contact lenses, or surgery. It is a growing concern, especially as more severe myopia is associated with a type of macular degeneration known as myopic macular degeneration(MMD). This degenerative condition specifically targets the macula, the central part of the retina responsible for central, straight-ahead vision.... Individuals with severe myopia, often referred to as "high myopia"(typically-6 diopters or more), are at a higher risk for developing MMD... MMD is an incurable condition that occurs when the elongation of the eyeball stretches the retina, leading to the eventual death of macular cells and the formation of a blind spot in the center of the visual field.

Dégénérescence maculaire myopique. Les myopies supérieures à -10 dioptries présentent un risque élevé de dégénérescence maculaire atrophique (ainsi que de glaucome, de cataracte ou de décollement de rétine). Les altérations maculaires évoluées sont visibles sous forme de zones d'atrophie choriorétinienne étendue, bien limitées, centrées sur la macula, souvent associées à un staphylome postérieur.

Smart eyewear is defined as eyewear incorporating a near-to-eye display. As used herein, near-to-eye display means a display, device, or system, such as a retinal projector, virtual retinal display, visualization element, head-mounted display, heads-up display, or other near-to-eye system, typically worn on the head of a user that generates an image near the eye. In a smart eyewear configuration, a display device is often mounted adjacent to an edge of each of the wearer's eyes and an image is typically displayed in the center of each lens. The location of the displayed image, therefore, forces the wearer to gaze in a direction to view the image generated by the display. Typically positioned near the user's eye, the display is aligned to the central region of the user's field of view to allow review of the displayed information with little or no head movement. This enables the user to view the display while also viewing the area outside the central region and interacting with the surrounding environment. In another embodiment, the displayed image is aligned to a region other than the central region of the user's field of view.

CONT

Near-eye display devices are configured to present images to a user via a display that is positioned close to the user’s eyes. For example, a head-mounted augmented reality display device may be worn on a user’s head to position a near-eye display directly in front of a user’s eyes. A near-eye display may be at least partially see-through to allow a user to view a real-world background in combination with displayed virtual objects. This may allow virtual objects to be displayed such that the virtual objects appear to exist within the real-world environment.

CONT

The technology provides one or more embodiments of a near-eye display (NED) device system. An embodiment of a NED device system comprises a near-eye display device including a near-eye support structure and a near-eye display (NED) supported by the near-eye support structure and having a display field of view. The NED system further comprises an image generation unit supported by the near-eye support structure which outputs image data which is optically coupled to the near-eye display (NED).

The rice blast disease is caused by the fungus Pyricularia grisea, which, in its sexual state, is known as Magnaporthe grisea. The disease can strike all aerial parts of the plant. Most infections occur on the leaves, causing diamond-shaped lesions with a gray or white center to appear, or on the panicles, which turn white and die before being filled with grain. P. grisea is highly specific to rice, although certain strains that don’t attack rice can harm weeds in the rice field. Once on a rice plant, the fungus rapidly produces thousands of spores, which are carried readily through the air, by wind or rain, onto neighboring plants.

In 1963, F. Vine and D. H. Matthews reasoned that, as basaltic magma rises to form new ocean floor at a mid-ocean spreading center, it records the polarity of the magnetic field existing at the time magma crystallized. As spreading pulls the new oceanic crust apart, stripes of approximately the same size should be carried away from the ridge on each side... Basaltic magma forming at mid-ocean ridges serves as a kind of "tape recorder", recording the Earth's magnetic field as it reverses through time. If this idea is correct, alternating stripes of normal and reversed polarity should be arranged symmetrically about mid-ocean spreading centers.

Circuit of electric field measurements of thunderclouds. ... The electric field mill is a device based on electrostatic induction. It consists of one or two electrodes which either rotate in an electrostatic field or become periodically exposed to a field by rotating vanes. Fig.46 illustrates a cylindrical field mill which consists of two cylinder halves that are electrically insulated from each other. An electric motor rotates the two halves in the electric field to be measured so that they become alternately exposed to both the positive and negative direction of the field. The result is that an alternating (ac) signal is generated across the two halves which can be easily amplified. ... Although not commonly used, the cylindrical field mill has the advantage that when mounted in a fixed position it can also indicate the direction of the field. This is accomplished by measuring the phase shift of the ac signal relative to the orientation of electric fields need to be measured.

CONT

The device normally used to measure atmospheric electric fields is a type of sensor called an electric field mill. It can be used on the ground to gain information about the field aloft, or it can be flown on an airplane or balloon.

The Space Shuttle stops within 50 meters of Mir, which is approximately one-half the length of a football field. From that position the Space Shuttle waits for clearance from Mission Control to continue. When the command is given to continue, the Reaction Control System is activated again and the Space Shuttle closes in on Mir at a speed of about 0. 05 meters per second until it reaches a distance of about 9 meters. There, the Space Shuttle stops again and waits for approximately 5 minutes. The Commander and Pilot make sure they can see the docking target clearly and fine-tune the alignment of the Space Shuttle with the docking target. A large black cross called the Stand-off Cross is mounted 30 centimeters(cm) above the back plate in the center of the target. When the Commander has the Stand-off Cross squarely in line with the docking target, he or she maneuvers the Space Shuttle and makes contact with the docking ring. Once a series of hooks is engaged, the Space Shuttle is then successfully docked with Mir.

The motion of the gyroscope can be seen as a special kind of a pendulum swing. The swing is not a straight one which passes underneath the suspension point. It is constantly deviated to the side and returns back earlier to the same height.

OBS

If in a gravitational field you support a rotating body in only a single point that is not the center of gravity(center of mass), there is a torque acting on it; if the rotation is fast enough to be associated with a substantial angular momentum and the change in angular momentum effected by that torque is comparatively small, you will observe precession. Gyroscopes used for navigation have to be suspended in their center of gravity and in a way that when changing direction of the box(airplane) around it no torque is applied through that suspension.

Four years ago, Soviet officials expressed interest to Carnegie-Mellon University's Field Robotics Center in using robots to venture inside the crippled Chernobyl nuclear reactor. J. Todd Simonds, Red Whitaker and Chris Fromme set up Redzone Inc. to respond.... Now Redzone is preparing to ship its next hazardous waste robot, a machine called a remote tank inspection system, to an Energy Department hazardous waste program in Hanford, Wash. After testing, the robot will eventually use its snakelike 43-foot arm to inspect and clean up a radioactive waste dump in Idaho.

The perimetric variation of visual acuity was first mapped in 1857 by Aubert & Förster, again by Hirschberg in 1887, and yet again by Werthein in 1894. Those early pioneers established that visual acuity falls inversely with eccentricity of target location from the center of the visual field, and that iso-acuity contours, or "isopters" to use a term invented by Hirschberg, are horizontally elongated ovals displaced by increasing amounts into the temporal visual field with increasing eccentricity.

As the aircraft descends through heights of 45 m to 22. 5 m above the runway... the pilot becomes more aware of the expanding runway scene as visual cues are observed to move rapidly outward from the center of expansion. This is due to the speed of the "flowing visual field" increasing at a rate inversely proportional to the distance of the pilot.

Alors que l'avion descend en passant à des hauteurs variant de 45 m à 22,5 m au-dessus de la piste (...), le pilote devient plus conscient de la position relative de la piste et il voit les repères visuels se déplacer rapidement à partir du point de fuite vers l'extérieur. Cette impression est due au fait que la vitesse du "champ visuel flottant" augmente en raison inverse de l'éloignement du pilote.
