If an RAPD is present, the response of both pupils will be less when the light is shone in one eye in comparison to the other. The light is then redirected across the nose as quickly as possible to the other eye and, again, the response of both pupils is assessed before returning to the first eye. 6 One eye is illuminated for two seconds and the response of both pupils is assessed. The swinging-torch test (for an RAPD) is then performed, ideally in a darkened room with a very bright light. The clinician should observe the direct pupillary response in the illuminated eye and the consensual response in the fellow eye. The response to testing each eye separately with a bright light source is then assessed. 6 The presence of ptosis and/or extraocular muscle involvement suggests a pathological process regardless of the magnitude of anisocoria. If anisocoria remains the same in both lighting conditions, and the difference between pupil sizes is no more than 2 mm, the aetiology is likely to be physiological. Pupil size should be assessed in both the dark (sympathetic-dominated dilation) and the light (parasympathetic-dominated constriction). If the patient’s irides are dark and the pupils are difficult to visualise, the clinician can use an ophthalmoscope to assess differences in the red reflex. A baseline measurement of pupil size should be made under ambient lighting conditions with both pupils equally illuminated. Any asymmetry of the colour of the two irides (heterochromia) should be noted. The examiner should observe the shape, size and location of the patient’s pupil. Testing this forms the basis of the swinging-torch test: if the response to shining a light in one eye differs from shining it in the other, this is referred to as a relative afferent pupillary defect (RAPD). 2,5ĭirect and consensual responses should be identical, whichever eye is illuminated. 2,5 Third-order sympathetic neurons then travel to the orbit with the internal carotid artery and its branches, ultimately innervating the dilator pupillae muscle in the iris. 5 From here, second-order sympathetic neurons travel back up the sympathetic chain to synapse in the superior cervical (stellate) ganglion. 2 Sympathetic pupillary fibres originate in the hypothalamus, travel down the brainstem and cervical spinal cord to exit at the first thoracic level. Parasympathetic pupilloconstrictor fibres travel in the oculomotor nerve, synapsing in the ciliary ganglion before reaching the sphincter pupillae muscle in the iris. 5 It is this bilateral innervation of the Edinger-Westphal nucleus that results in both direct and consensual responses to light shone in one eye. 2 Information from the optic nerve passes to the ipsilateral pretectal nucleus and then on to the Edinger-Westphal nuclei on both sides. The pupillary light response involves both afferent (optic nerve) and efferent (oculomotor nerve and sympathetic) pathways. Examination should include assessment of visual acuity, visual fields to confrontation, pupil testing, extraocular motility and whether or not ptosis is present. 5 It is important to ask about previous or current malignancies and neck trauma. Associated visual and/or neurological symptoms should be sought, including visual blurring, visual loss, disturbance of visual fields, or diplopia. 2,5Ī thorough history should include asking about the use of new medications or inadvertent ocular contact with foreign substances by rubbing the eyes. 2–4 Non-physiological anisocoria indicates disease of the sympathetic or parasympathetic pathways supplying the pupil, or a problem with the iris itself. ![]() Physiological anisocoria is common: approximately 20% of normal people have different-sized pupils. 1 This article aims to guide management in both of these situations. Indeed, new onset anisocoria may be an early sign of a life-threatening emergency. The general practitioner (GP) may discover anisocoria during examination for a seemingly unrelated problem. The aetiology may be physiological, pathological or pharmacological. A difference in pupil size between the eyes is known as anisocoria. ![]() READ ALSO: How do you remove contact solution from wood?

There were comedy items to pick up, hats to collect, muffled voice lines to blurt - you know the sort of thing. We raced, in randomly assigned cohorts of eight, and for three laps per track, in go-karts driven by the most beloved characters from the Garfield franchise. At first, of course, it was gloriously simple - we raced. But the darkness was necessary, I think: a rocky shore, shrouded in haggard gloaming, for GKFR’s final revelations to bring dawn to. Where I felt genuinely frightened, if I am honest. Garfield Kart Furious Racing showed me the best of myself, and the worst of myself.įor a while, it would lead me to a place where I felt very lost indeed. Wretched and capering, they were beasts mean apes with funneled lips and grasping hands, boneheaded enough to be treating this as a knockabout competition a bit of fun. Sometimes, I loved the other racers - they were fellow pilgrims the only people who could relate to the intensity of what I was experiencing with Garfield Kart Furious Racing, and the only people who could diffuse its pain, by the certain knowledge that they shared it. Even then, were we thespians, using our own talents as fulcra against which to shift the weight of GKFR’s genius? Or just a pantomime mob, amplifying every emotional peak and trough with our animal passion and noise? At times over the four days of the review period (during which, I think, I spent all of 20 hours away from my gaming chair), both felt true. ![]() Our PCs were the stage, and our mouse clicks were the words of power, affecting the will of Garfield Kart Furious Racing in its desire to be told to the world. The text of a play is a spell: an invocation of power, but one which cannot take full effect until imbued with physicality by performers on a stage. For if physics is one way to codify the business of magic, then theatre is another. I will do so only in the archaic, theatrical sense of the word. Just as I am loathe to call Garfield Kart Furious Racing a ‘game’, so too am I unhappy to call us ‘players’. And indeed, it was not: 3am arrived, the code was activated, and the players began to race.īefore we get into the thick of it, however, one more short note on terminology. But if Garfield Kart Furious Racing says anything unambiguously, it’s that the clock can never be stopped. It would require us, like the mass of cells teeming in a growing zygote, to transcribe genotype into phenotype.Īnd we were ready: a legion of us, fingertips crackling above our keyboards with the electricity of anticipation, as we awaited the crucial hour. Less of a game, then, and more of a gamete - at least for that moment. To think now, that all the genius, all the singular agony of the work, was condensed into just a few million lines of alphanumeric shorthand, is as hard to comprehend as the information required to build a human being archived in the chemical broth at the heart of a cell. Only when this art was sullied with our own digital hands, could it be real. Only when that box was opened, could we know if the cat was Garfield. ![]() A sealed box, if you will, containing a cat. In the early hours of last Tuesday, as I and a thousand others waited for the 3am activation of our review copies, GKFR existed entirely in potentia: a few million lines of code, disembodied on some server in Northern California, waiting to be defined through our shared experience. ![]() According to the Copenhagen Interpretation of quantum mechanics, by observing a phenomenon, we cannot help but change it - and never has this been more true than in the case of Garfield Kart Furious Racing. Could we call it a text, perhaps? Possibly - but one that can only be considered complete in the act of its being engaged with. It’s heartbreaking, really, to resort to a term so crude as “game” to describe Garfield Kart Furious Racing. And indeed, in writing as a critic, I expand the work yet further. In a sense, then, I am reviewing my own work - for in engaging with GKFR, I became one of its authors. Because GKFR, you see, is a collaborative effort - directed, certainly, by its developers at Artefacts Studio, but only comprehensible as an ever-changing consensus between the game itself, its players, and its critics. In the plainest terms, I would say I participated in it: I offered my own myopic contribution, alongside millions of others, to form the baroque gestalt of the work as a whole. I cannot say, in truth, that I played Garfield Kart Furious Racing. ![]() Basically, the code needs to be running in order for Visual Studio Code to attach.įinally, start the debugger in Visual Studio Code.

The lens-like antenna is placed inside an enclosure that contains micro-electromechanics to emit a radar signal. The current version, produced with an acrylic, weighs about 10 grams. Lunenwave’s antenna can focus a returning radar signal to one focal point or scale that up to hundreds of points of focus. He reduces the Luneburg antenna down to the size of a ping-pong ball – while maintaining the necessary complexity of the dielectric properties created via the thousands of tiny chambers. After two years, he was able to demonstrate the ability to “print” the Luneburg-inspired sphere, which contains 6,500 uniquely designed miniature chambers. Xin had been working with 3D-printing, polymer-jetting techniques since 2007. He’s also the chief technology officer for Lunewave. in physics from the Massachusetts Institute of Technology, now heads the University of Arizona’s Millimeter Wave Circuits and Antennas Laboratory. Nearly 15 years ago, Hao Xin, a professor of electrical and computer engineering at the University of Arizona, started exploring how Luneburg’s approach might be used in new applications, such as autonomous driving and 5G communications. The design also allows for fast, single-snapshot readings rather than comparatively slower conventional radar scanning. That’s unfortunate, because the intricate pattern of chambers and branches inside a spherical Luneburg radar antenna imparts 360-degree sensing capabilities. But because Luneburg lenses are commonly between the size of a large grapefruit and a soccer ball, they are too big for use in cars. The lens, which serves as an efficient passive reflector, is used in fighter planes to enhance the signature of a radar signal. German-American Rudolf Luneburg, a professor of mathematics and optics, first proposed his unique gradient-index lens in 1944. Tucson, Arizona-based Lunewave was founded in 2017. That shortcoming motivated Hao and John Xin, the brother co-founders of Lunewave, to commercialize a spherical radar antenna based on the Luneburg lens design created three-quarters of a century ago. And it has a low cost, which depending on quality and scale of production, is between about $50 to a few hundred dollars per unit.īut the relatively inexpensive, planar, phased-array radar antennas commonly used for functions like adaptive cruise control don’t have the resolution needed for higher levels of automated functions. It’s good at detecting objects from long distances of a couple hundred meters or more, even in bad weather. Like all sensors intended an automated vehicle (AV), radar has strengths and weaknesses. Radar sensing has been used for various functions in passenger vehicles for more than two decades. ![]() The number of horizontal antennas per panel tightly depends on the required values of the link quality metrics, potentially leading to a non-uniform geometry between sides and front or back panels.The Luneburg-inspired sphere, about the size of ping-pong ball, contains 6,500 uniquely designed miniature chambers.” ![]() Regarding the horizontal geometry, four panels on the roof's edges provide good coverage and link quality. A shaped beam in the vertical plane based on three preset radiating elements is proven to be robust enough against self-scattering effects on the vehicle body. Connectivity parameters such as Signal-to-Interference-plus-Noise Ratio (SINR) and outage probability are optimized based on the array topology. The study considers both the influence of the vehicle itself at radiation pattern level and the impact of the urban traffic on physical layer parameters. This paper presents an approach to design mmWave vehicular multi-antenna systems with beamforming capabilities considering the practical limitations of their usage in real vehicular environments. Millimeter-wave (mmWave) connectivity represents a paramount research field in which adequate geometries of antenna arrays must be provided to be integrated in modern vehicles, so 5G-V2X can be fully exploited in the Frequency Range 2 (FR2) band. The transformation of the automotive industry towards ubiquitous connection of vehicles with all kind of external agents (V2X) motivates the use of a wide range of frequencies for several applications. |
