Description: The Objective of this project is to develop a system to keep the vehicle secure and protect it by the occupation of the intruders.

Scope: We can’t take care of ours while in running by less conscious. If we done all the vehicles with automated security system that provides high security to driver, also gives alarm.

Function: This project involves measure and controls the eye blink using IR sensor. The IR transmitter is used to transmit the infrared rays in our eye. The IR receiver is used to receive the reflected infrared rays of eye. If the eye is closed means the output of IR receiver is high otherwise the IR receiver output is low. This to know the eye is closing or opening position. This output is give to logic circuit to indicate the alarm. This project involves controlling accident due to unconscious through Eye blink. Here one eye blink sensor is fixed in vehicle where if anybody looses conscious and indicate through alarm.

Blink Essay

...Cecilia Abate English 114 10/6/10 Blink: A Brush With Subconscious Cognitive Reflexes Truth is often a difficult thing to discern. There is a common assumption that moving too fast and not thinking decisions through will result in a product of weak clarity and perhaps also weak quality. As a society, we encourage our loved ones to think things through, reconsider, and “sleep on” information in order to weigh all the possibilities and come to the best possible conclusion. However, Gladwell, the author of Blink, suggests differently. In direct contrast to what most of us have been told, he pushes us towards quick thinking as a profitable and easy option – to pay attention to one's subconscious is to harness the power of thoughts you did not know you were having. If you pay attention to your “gut feeling”, your decisions will take less time and may be more accurate. This is exactly the idea of thin slicing, a concept that many of us utilize in our daily lives. I have had a handful of situations where I immediately noticed and decided upon something, then thought it through and came to a completely different answer with what I thought was logical and sensible reasoning. This is exactly what Gladwall is arguing against-- he says that we should lean towards trusting our snap judgements. Once in tune with this concept, I realized that I use this tool already-- with friends, judging couples, for instance, or comparing people I barely knew and making assumptions based off what......

Gillette Sensor

...mismo tiempo construir 2 nuevas fábricas, una en Boston y otra en Berlín. El éxito o fracaso de Sensor tendrá un impacto significativo en el futuro de la organización. Análisis de Situación: Los factores claves a considerar en la recomendación e implementación final son: El desarrollo del sistema de afeitar Sensor: • Sensor no es cualquier sistema de afeitado. Tiene detrás 10 años de Investigación y Desarrollo que han significado más de 75 millones de dólares y 50 millones en equipos productivos. Es un proyecto coherente con la política de Gillette acerca de la innovación, considerada fundamental para el crecimiento de la compañía. Además, los prototipos han sido muy exitosos y han obtenido los mejores resultados en todas las categorías consideradas: apurado, comodidad y aspecto. Importancia de la publicidad para los productos Gillette: • Para Gillette, la publicidad durante la etapa de lanzamiento de un producto, es vital ya que hace que el consumidor conozca el producto y lo induzca a probarlo. Luego se vende solo. Ya lo señalaba el fundador King Gillette “todo el éxito de este negocio depende de la publicidad”. • Según un estudio encargado por Gillette, la imagen de marca entre los jóvenes había perdido fuerza. Establecer una estrategia publicitaria global que fortalezca la marca es coherente con esta situación. La competencia no representa un gran riesgo para Sensor: • Aunque los competidores reaccionan con rapidez, las imitaciones no le quitan......

...MAJOR PARTS OF THE EYE AND THEIR FUNCTIONS Iris * The colored part of the eye that surrounds the pupil. * It contracts and expands opening and closing the pupil, in response to the brightness of surrounding light. * This helps in dilating and making the pupil smaller. Pupil * The dark center of the eye, where light rays enter * The pupil either dilates or contracts with the help of the iris * This controls the amount of light entering the eye so that the retina and lens doesn't get damaged Sclera * Tough fibrous tissue, serves as a protective shield * Provides structure and safety for the inner workings of the eye, but is also flexible so that the eye can move to seek out objects as necessary. * Keeps the eyes shape and protects its delicate internal parts. Retina * Composed of nerve endings responsible for reception and transmission of light impulses. Lens * Transparent body located behind the iris and in front of the vitreous humor, refracts light rays to bring them into focus on the retina * The lens is a converging lens so that it can create a real image on the back wall of the eye.  * This allows us to focus on something close to us and far away. Cornea * The cornea is the outer covering of the eye. * This dome-shaped layer protects your eye from elements that could cause damage to the inner parts of the eye. * The cornea also allows the eye to properly focus on light more......

Life Changes in a Blink of an Eye

...Life Changes in a Blink of an Eye Life is not what it seems; we don’t recognize ourselves as we’re all lost. I think; therefore, I doubt whether I am or not. One’s life is not what it seems, nor is what we were taught since childhood. The idea of living life is reduced to a life tacked by common sense. My own significant weight is what led me down the path of realization. My life had a slight change July 9, 2010, I was charged with two felonies. January 1, 2010 was when everything began. I started dating a young man that wasn’t right for me and I knew it, but I looked past it and gave him a chance. I was in deep LIKE. His lifestyle wasn’t the legal lifestyle and his friends wasn’t right either, but I looked pasted all the wrongs and continued on with my relationship. I would do anything for this guy, I only asked one thing from him and that was to not put me in any trouble and he agreed; but his friends had a different view on others life that wasn’t theirs. The summer of 2010 was when everything started to change. We decide to move in together and continue on with our relationship. Life and Love can be a tricky thing. Rather I knew right from wrong I believe he was right for me. Again, the friends were a issue and I knew it but I trusted him to have them in order and make sure or house was our home. Life is not what you dreamed it to be. July 9, 2010 my partners’ friend asked for a ride and when I dropped him off I notices he left a black book bag in my vehicle, I......

Attentional Blink

...Practicum Blok 2.4 Perceptie Verslag 2: Resultaten Attentional Blink Voor ons experiment hebben we een ‘repeated measures ANOVA’ uitgevoerd. Hiervoor zijn de scores van de proefpersonen gebruikt van de ZAP ‘attentional blink’. De scores tonen het percentage aantal correcte letters die men reproduceert na het tonen van één of twee letters in de cijferreeks (zie appendix). Van tevoren verwachtten we hoe groter de afstand is tussen de aangeboden targetletters, hoe vaker de tweede letter wordt herkend. Tevens verwachtten we dat de aandacht voor de eerste targetletter interfereert met de tweede, waardoor het meer moeite kost om de tweede targetletter te reproduceren. Andersom verwachtten wij dit niet. De resultaten van onze anova tonen aan dat er een significant verschil is tussen de scores van de proefpersonen op het reproduceren van de tweede letter (Target2). Het effect van de ‘Mauchly’s Test of Sphericity’ was niet significant (p = .803). Daarom kijken we naar ‘Sphericity Assumed’, welke een significant verschil toont, F(2, 18) = 37.109, p < .001. Om uit te vinden waar het verschil precies zit kijken we naar de ‘Bonferroni pairwise comparison’. Daarin zien we dat er een significant verschil is tussen de tweede conditie (Afstand3) en conditie 1 (Afstand1) en tussen conditie 2 (Afstand3) en conditie 3 (Afstand7). De proefpersonen identificeren in conditie 2 significant minder targetletter dan in condities 1 en 3. Tussen conditie 1 en conditie 3 is er geen significant......

Blink - the Power of Thinking Without Thinking

...in Athens. He took one look at the kouros and blanched. “Anyone who has ever seen a sculpture coming out of the ground,” he said to her, “could tell that that thing has never been in the ground.” Georgios Dontas, head of the Archeological Society in Athens, saw the statue and immediately felt cold. “When I saw the kouros for the first time,” he said, “I felt as though there was a glass between me and the work.” Dontas was followed in the symposium by Angelos Delivorrias, director of the Benaki Museum in Athens. He spoke at length on the contradiction between the style of the sculpture and the fact that the marble from which it was carved came from Thasos. Then he got to the point. Why did he think it was a fake? Because when he first laid eyes on it, he said, he felt a wave of “intuitive repulsion.” By the time the symposium was over, the consensus among many of the attendees appeared to be that the kouros was not at all what it was supposed to be. The Getty, with its lawyers and scientists and months of painstaking investigation, had come to one conclusion, and some of the world’s foremost experts in Greek sculpture—just by looking at the statue and sensing their own “intuitive repulsion”—had come to another. Who was right? For a time it wasn’t clear. The kouros was the kind of thing that art experts argued about at conferences. But then, bit by bit, the Getty’s case began to fall apart. The letters the Getty’s lawyers used to carefully trace the kouros back to the Swiss......

..."In the first two seconds of looking –in a single glance – they were able to understand more about the essence of the statue than the team at the Getty was able to understand after fourteen months . . . Blink is a book about those first two seconds." Gladwell begins his introduction with the story of a kouros – an ancient Greek sculpture of a young naked male – that was acquired by the J. Paul Getty Museum in 1983. Kouroi are very rare. As a result this particular kouros was being sold for $10 million. Because of the hefty price tag, the Getty Museum was very careful when testing to see if the kouros was a forgery. However, after 14 months of analysis, the Getty determined that the kouros was in fact real, and bought the statue. Many scholars did not agree that the kouros was real. To them, something about the statue didn’t look right. When Thomas Hoving, the former director of the Metropolitan Museum of Art in New York, looked at the statue the first word that came to his mind was “fresh”. When Angelos Delivorrias, director of the Benaki Museum in Athens, first laid eyes upon the statue he felt a wave of immediate disgust. For a long time the validity of the kouros was hotly debated. Finally, the Getty’s case began to fall apart. As it turned out, a lot of the documents used to prove the statue’s authenticity were forged. Also, as experts began to examine the statue in great detail, they came to the realization that it used a hodgepodge of styles from many different......

...Vision on the Stanford Artificial Intelligence Robot Lawson Wong1 Grasping is an essential ability for manipulation; for robots such as the Stanford Artificial Intelligence Robot (STAIR) to be resourceful in real-world environments, they must know how to grasp. While this is a well-studied problem in the case when a full 3-D model of the target object is known, it is difficult for real-world scenarios, where the robot must rely on imperfect perception to model the scenario. This paper presents a novel approach for grasping that only uses local 3-D information acquired from sensors. Given data of the environment from 3-D sensors, our algorithm generates arm/hand configurations that may potentially achieve a good grasp, then computes features of these candidates to select the best candidate and execute its grasp. These features capture desirable properties of potential grasps based on sensor data, which our learning algorithm then uses to predict how likely the grasp will be successful. This algorithm was tested on STAIR in real-world grasping of single objects and of objects in cluttered environments. Significant improvements in both cases were found. Introduction As the field of artificial intelligence becomes increasingly advanced and integrated, it is time to revisit the half-century old “AIDream,” where intelligent robotic agents were envisioned to interact with the general human population. To this end, the Stanford Artificial Intelligence Robot......

Blink-182 Essay

...crowded shelf that held my old and forgotten materials. Sifting through the junk, something shiny caught my eye. I reached for it and pulled it out, examining it’s glimmering circular shape. I flipped over, and saw 3 distinct icons: a red plane, a yellow pair of pants, and a green jacket. It was a CD. I couldn’t quite place where I had seen this from before; then a vague memory of seeing it being shoved into the car stereo trickled into the back of my mind. Eager to see what artist it was by, I ran down the stairs and slipped it into the computer. An artist name popped up: blink-182. I gasped. The name triggered musical memories… the CD was called “Take Off Your Pants and Jacket”. “Could it be?!” I shouted, accidentally aloud. I downloaded it to the computer then to my iPod. Scrambling for my headphones, I finally felt the rubbery cord and yanked it out. Plugging it into my iPod, I hit play. The music flowed through my ears to my brain, and I stopped breathing for 30 seconds. I flipped through the songs, and each of them triggered memories. I listened to the lyrics, and it felt as if my heart stopped beating. They were so realistic, so true, so relatable… but each song conveyed a message. Each song told me how to get over a break-up, or how not to let anyone affect my personality, and to just be myself. Not be afraid of who I was, and just be honest. Blink-182 changed my attitude, and they also helped me through friend dramas, which I cannot imagine would have been......

Car Sensor

...countries, traffic violations leading to car crashes results in thousands of deaths each year, most of which occur because of breaking speed limits and unauthorized overtaking. So making a smart system which could record these violations and dispatch them for higher authorities has become a need in today's world. Making such a system drivers would feel the police presence on roads and as a result they will obey traffic laws more than ever. There are many system used in this field as follows:  The system is designed via RFID and M-RFID technology. This system has been designed on the basis of two traffic signs i.e. no overtaking sign and speed limit sign. The aforementioned system is also equipped with line and speed tracking sensors and is used for dispatching traffic violations to traffic department servers in real time. Therefore, this cycle forms a smart violation Manuscript received November 12, 2013; revised March 22, 2014. ©2014 Engineering and Technology Publishing doi: 10.12720/jtle.2.3.164-171 PREVIOUS WORK 164 Journal of Traffic and Logistics Engineering Vol. 2, No. 3, September 2014 not (speed violation).

Sensor and Control

...Sensors & Controls SECTION 8 Tips for Daylighting with Windows OBJECTIVE Design and install a control system to dim lights and/or turn them off when there is adequate daylight. • Reduce lighting energy consumption with automatic controls. • Use a lighting specialist for best results with the control system. KEY IDEAS General • Sensors “measure” light by looking at a wide area of the office floor and work surfaces from a point on the ceiling. The sensor’s signal is then used by the control system to dim or turn off the electric lights according to the available daylight. These simple components are needed to save energy in daylighted spaces. • Controls can respond to many variables. To save lighting energy, controls are typically designed to respond to daylight and a host of other inputs (e.g., occupancy sensors, weekend/holiday/nighttime schedules, etc.). • Include all control documentation in the construction documents. This should include clearly developed control schematics, control sequences, calibration instructions, maintenance plans and checklists, and clear testing procedures. • Lighting controls and sensors must be properly calibrated and commissioned prior to occupancy. This helps ensure energy savings and reduces the likelihood of complaints from occupants. • Take special care to document integrated control systems. Control schematics are critical where different building systems (e.g., lighting, mechanical, etc.) come together.......

They Eye

...THE HUMAN EYE The eyeball is a sphere that lies buried in fat inside the orbit, or space in the skull. The adult human eye has a diameter of approximately 2.5 cm. Each eyeball has six ocular muscles attached to it. These muscles move the eye. The eyelids are like moveable curtains in front of the eye and consist of three layers; the skin, the muscles that open and close the lids, and the cunjunctiva which is a membrane that lines the eyelids and covers part of the eyeball. The eyelids serve as protection from injury, as well as, regulate the amount of light that enters the eyes. Blinking also wipes the surface of the eyes clean, and keeps a layer of a slightly salty fluid over the front of the eyes. This fluid, tears, is produced in lacrimal glands, or tear glands, which are located under the outer part of the upper eyelid and is collected and drained through tiny canals within the upper and lower lids near the nose. The tears eventually flow into the nasal passages and are swallowed. The eyelashes act as a protective screen that keeps particles out of the eye. The eyebrows and protruding edges of the facial bones form a protective wall around the eye. The surface of the eyeball consists of three basic layers; the sclera, the middle layer, and the retina. The sclera is the outer layer of the eyeball. At the front of the eye, the sclera becomes the clear and transparent cornea, through which light enters. The middle layer has three......
