The main cause for the high frequency of alarms The second half (individual) consisted of solution are false alarm rates that can be as high as benchmarking, choosing a final design concept 70% [1] and in some cases even 99% [2]. This followed by an extended technology research causes the hospital staff to become desensitized and a final user evaluation. to alarms that can be critical. This behaviour is the typical definition for a phenomenon known as alarm fatigue [3], which was the number one health technology hazard in 2015 for the fourth Solution consecutive time [4]. “Monocle” is a smart glass for nurses that provides Furthermore, hospital device manufacturers quicker access to information, transmitting any are obliged by law to equip their products with device sound only to the responsible nurse - to auditory alarms [5] - exposing everybody in an reduce the noise in ICU’s. Quicker and mobile ICU to the noise instead of only alerting the access to information prevents stress, facilitates responsible staff. work-flow and enables nurses to spend more valuable time at the patient’s bedside. Compared to existing smart-glasses, monocle Assignment is specifically designed for the unique context of a hospital environment, taking into account Erasmus MC hospital asked for concepts for a hygiene, ergonomics, durability and useful more silent ICU by optimizing monitoring and features such as voice dictation and barcode signalling from the perspective of the nursing scanning. staff and looking at wearable technologies.

An environment with project, one of the solutions, however, stuck out like and to trigger ideas about which steps are no auditory alarms at all - at least none that can by suggesting silent alarms that selectively notify necessary to get there. be heard by everyone. single nurses only, thus reducing the overall noise level.

Bone-conduction headphones exist but never had a successful breakthrough since their audio quality usually never matches conventional headphones. Their biggest advantage, however, lies in the possibility to hear your surroundings since the ear-canals are not covered. This feature was found to be very useful for the ICU context since nurses could be solely exposed to sounds while still being able to listen to patients and co- workers. Furthermore, bone conduction headphones would offer a hygienic solution for swapping devices between nurse shifts. Bone conduction headphones audio quality is sufficient to transmit voices of phone calls and alarm sounds that usually never require the same high audio quality as music.

  • Dreams of Our Children 2020: the Year Our Children Need Clarity January 2, 2020 by Tom Deighan I Have One Good Eye and One
    Dreams of Our Children 2020: The Year our Children Need Clarity January 2, 2020 by Tom Deighan I have one good eye and one bad eye, depending on how you look at it. My eye doctors call it monovision, which means one eye is good up close and the other eye is good far-off. As a result, I can read and drive without glasses or contacts, depending upon which eye I favor. It also means I am eligible to wear a monocle, but that would just be silly without a top hat. After all there is a fine line between looking distinguished and looking like The Penguin. Consequently, I save the monocle and top hat for only the most auspicious of occasions, like meeting the Queen of England. Monovision requires the brain to merge one blurry image with one clear image, so it takes some getting used to, and unfortunately, some people simply cannot function with one myopic and one presbyopic eye. The mind cannot always reconcile the polarized visions, so many people struggle ultimately having to close one eye to make sense of the world, depending on the situation. Since my brain is naturally confused, it accepts both the blurry and the clear fairly well. On occasion, however, I have to close one eye to focus. If you ever think I am winking, I am really just temporarily confused. It is not always possible to make sense of such different perspectives. As we enter a new decade, I cannot help but see the similarities in our nation. We seem gripped by two very polarizing visions of our nation and culture.

  • Information About Glasses
    Glasses Webquest The history of glasses The first recorded use of a corrective lens was by the last Roman Emperor Nero, who lived from December 5th, 37 AD until June 9, 68 AD. He watched games with gladiators using an emerald. It’s not quite clear when glasses were invented, but they were used quite commonly in northern Italy in the late 280s. Also Marco Polo, a Venetian trader and explorer who was one of the first to travel the Silk Road to China, reported that he had seen many pairs of glasses in China as early as 275. New worlds A detail from a painting by Tommaso da Modena in 1352, showing a portrait of Hugh de Provence wearing glasses. Glasses for correcting far-sightedness were probably invented by Salvino D’Armate of Pisa or by Alessandro Spina of Florence. These very early glasses weren’t supported by pads on the nose or by pieces of wire placed over the ears. They were a pince-nez, a monocle or a lorgnette. So you either had to hold them in place by hand or you had to fix them on your nose or in your eye socket with pressure. pince-nez monocle lorgnette Glasses with arms were invented in the 600s. It was in 604 that Johannes Kepler wrote that two different types of lenses could correct far-sightedness and short-sightedness. The American scientist Benjamin Franklin, who suffered from far- and short-sightedness, invented bifocals in 784. He was tired of changing between two pairs of glasses. So he cut each pair horizontally and made one single pair.

  • History of Eyeglasses
    History of Eyeglasses WHAT MAN DEVISED THAT HE MIGHT SEE By: Richard D. Drewry, Jr., M. D. Converted to HTML by: Ted Wei, Jr., M.D. Apparently no visual instruments existed at the time of the ancient Egyptians, Greeks, or Romans. At least this view is supported by a letter written by a prominent Roman about 100 B. C . in which he stressed his resignation to old age and his complaint that he could no longer read for himself, having instead to rely on his slaves. The Roman tragedian Seneca, born in about 4 B.C., is alleged to have read "all the books in Rome" by peering at them through a glass globe of water to produce magnification. Nero used an emerald held up to his eye while he watched gladiators fight. This is not proof that the Romans had any idea about lenses, since it is likely that Nero used the emerald because of its green color, which filtered the sunlight. Ptolemy mentions the general principle of magnification; but the lenses then available were unsuitable for use in precise magnification. The oldest known lens was found in the ruins of ancient Nineveh and was made of polished rock crystal, an inch and one-half in diameter. Aristophanes in "The Clouds" refers to a glass for burning holes in parchment and also mentions the use of burning glasses for erasing writing from wax tablets. According to Pliny, physicians used them for cauterizing wounds. Around1000 A. D. the reading stone, what we know as a magnifyingglass, was developed. It was a segment of a glass sphere that could be laid against reading material to magnify the letters.

Knox 1The Institute of Optics, University of Rochester, Rochester, NY, USA 2Clerio Vision, Inc., Rochester, NY, USA Ever since the first documented use of spectacles for vision correction around the mid-1200s, we have been looking for better ways to correct human vision. A wide range of technologies have been developed to correct vision, including eyeglasses that now can help mitigate presbyopia, more comfortable contact lenses that can be used for extended times, intraocular lenses for treating cataracts, and, most recently, LASIK surgery for cutting and reshaping the human cornea directly. All of these are invasive to certain degrees, and it is desirable to develop less invasive forms of vision correction. We have developed an alternative approach to vision correction involving directly changing the index of refraction of ophthalmic materials by femtosecond laser micromachining. We discuss metrology, wavefront, and human visual testing results in hydrogel materials that are commonly used for contact lenses and intraocular lenses, as well as fully scaled vision correctors written directly into the cornea stroma layer in live eyes. This new technique has been developed to be non-invasive and has a significant accompanying patent portfolio. We describe the research and development efforts, which started in 2003, leading to this new approach to vision correction that we refer to as LIRIC: Light Induced Refractive Index Change.
