Doing so could lead to serious injury or death. This device does not include the self-checking redundant circuitry necessary to allow its use inpersonnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition.ModelsFixed-Field Mode OverviewT30 self-contained fixed-field sensors are small, powerful, infrared diffuse mode sensors with far-limit cutoff (a type of background suppression). Their high excess gain and fixed-field technology allow detection of objects of low reflectivity, while ignoring background surfaces.The cutoff distance is fixed. Backgrounds and background objects must always be placed beyond the cutoff distance.Fixed-Field Sensing – Theory of OperationThe T30 Fixed-Field sensor compares the reflections of its emitted light beam (E) from an object back to the sensor's two differently aimed detectors, R1 and R2. See Figure 1 on page 2. If the near detector's (R1) light signal is stronger than the fardetector's (R2) light signal (see object A in the Figure below, closer than the cutoff distance), the sensor responds to the object. If the far detector's (R2) light signal is stronger than the near detector's (R1) light signal (see object B in the Figure below, beyond the cutoff distance), the sensor ignores the object.•To order the 9 m (30 ft) PVC cable model, add the suffix "W/30" to the cabled model number. For example, T306E W/30.•To order the 4-pin M12/Euro-style integral quick disconnect model, add the suffix "Q" to the model number. For example, T306EQ.•Models with a quick disconnect require a mating cordset.T30 Sensors DC-Voltage SeriesOriginal Document121524 Rev. C2 October 2018121524The cutoff distance for the T30 is fixed at 200, 400, or 600 millimeters (7.9 inch, 16.7 inch, or 23.6 inch). Objects lying beyond the cutoff distance are usually ignored, even if they are highly reflective. However, under certain conditions, it is possible to falsely detect a background object (see Background Reflectivity and Placement on page 2).CutoffNearDetectorFarDetector ArrayAxis EmitterObject is sensed if amount of light at R1is greater than the amount of light at R2Figure 1. Fixed-Field ConceptIn the drawings and information provided in this document, the letters E, R1, and R2 identify how the sensor's three optical elements (Emitter "E", Near Detector "R1", and Far Detector "R2") line up across the face of the sensor. The location of these elements defines the sensing axis, see Figure 2 on page 2. The sensing axis becomes important in certain situations, such as those illustrated in Figure 5 on page 3 and Figure 6 on page 3.Sensor SetupSensing ReliabilityFor highest sensitivity, position the target for sensing at or near the point of maximum excess gain. Maximum excess gain for all models occurs at a lens-to-object distance of about 40 mm (1.5 in). Sensing at or near this distance makes the maximum use of each sensor’s available sensing power. The background must be placed beyond the cutoff distance. Note that the reflectivity of the background surface also may affect the cutoff distance. Following these guidelines improves sensing reliability.Background Reflectivity and PlacementAvoid mirror-like backgrounds that produce specular reflections. A false sensor response occurs if a background surface reflects the sensor's light more to the near detector (R1) than to the far detector (R2). The result is a false ON condition (Figure 3 on page 3). Correct this problem by using a diffusely reflective (matte) background, or angling either the sensor or the background (in any plane) so the background does not reflect light back to the sensor (Figure 4 on page 3). Position the background as far beyondthe cutoff distance as possible.An object beyond the cutoff distance, either stationary (and when positioned as shown in Figure 5 on page 3), or moving pastthe face of the sensor in a direction perpendicular to the sensing axis, may cause unwanted triggering of the sensor if more light is reflected to the near detector than to the far detector. Correct the problem by rotating the sensor 90° (Figure 6 on page 3). The object then reflects the R1 and R2 fields equally, resulting in no false triggering. A better solution, if possible, may be to reposition the object or the sensor. - Tel: +1-763-544-3164P/N 121524 Rev. CCutoff Reflective BackgroundFigure 3.

Object Beyond Cutoff - Problem E = EmitterR2 = Far Detector R1 = Near DetectorCutoff ReflectiveBackgroundorMoving ObjectA reflective background object in this position or moving across the sensorface in this axis is ignored.Figure 6. Object Beyond Cutoff - SolutionColor SensitivityThe effects of object reflectivity on cutoff distance, though small, may be important for some applications. It is expected that at any given cutoff setting, the actual cutoff distance for lower reflectance targets is slightly shorter than for higher reflectance targets.This behavior is known as color sensitivity.For example, an excess gain of 1 for an object that reflects 1/10 as much light as the 90% white card is represented by thehorizontal graph line at excess gain = 10. An object of this reflectivity results in a far limit cutoff of approximately 190 mm (7.5 inch)for the 200 mm (8 inch) cutoff model, for example; and 190 mm represents the cutoff for this sensor and target.These excess gain curves were generated using a white test card of 90%reflectance. Objects with reflectivity of less than 90%reflect less light back to the sensor, and thus require proportionately more excess gain in order to be sensed with the samereliability as more reflective objects. When sensing an object of very low reflectivity, it may be especially important to sense it at or near the distance of maximum excess gain.Wiring DiagramsCabled Emitters–+NPN Standard–+PNP Standard–+Key:Wire 1 = Brown Wire 2 = White Wire 3 = Blue Wire 4 = BlackP/N 121524 Rev.

HumorIf you see humor as an optional form ofentertainment, you’re missing some of its biggest benefits: Humor makesaverage-looking people look cute and uninteresting people seem entertaining.Studies show that a good sense of humor even makes you seem smarter.Best of all, humor raises your energy, and thatcan have an effect on everything you do at school, at work, or in your personallife. The increase of energy will even make you more willing to exercise, andthat will raise your overall energy even more.Humor also transports your mind away from yourdaily troubles. Humor lets you better understand life and sometimes helps youlaugh at even the worst of your problems.In my experience, most people think they have asense of humor, and to some degree that’s true. But not all senses of humor arecreated equal. So I thought it would be useful to include some humor tips foreveryday life.You don’t have to be the joke teller in thegroup in order to show your sense of humor. You can be the one who directs theconversation to fun topicsthat are ripe for others to add humor. Every partyneeds a straight person. You’ll appear fun and funny by association.When it comes to in-person humor, effort countsa lot. When people see you trying to be funny, it frees them to try itthemselves. So even if your own efforts at humor fall short, you might befreeing the long kept humor in others. People need permission to be funny insocial settings b ecause there’s always a risk that comes with humor. Forin-person humor, quality isn’t as important as you might think. Your attitudeand effort count a lot.Some people--and I was one of them--believe thathumorous complaints about the little problems of life make humor, and sometimesthat is the case. The problem comes when you start doing too muchcomplaint-based humor. One funny observation about problem in your life can befunny, but five is just complaining, no matter how smart you think you are.Funny complaints can wear people out.Self-deprecating humor is usually thesafest type, but here again you don’t want to overshoot the target. Oneself-deprecating comment is a generous and even confident form of humor. Youhave to be at least a bit self-assured to laugh at yourself in front of others.But if you do it too often, you can transform in the eyes of others from aconfident joker to a Chihuahua dog.HumorBenefits of humor●Humoris form of ________.

车载毫米波雷达基本成像原理Millimeter wave radar is a key technology in the field of automotive safety and autonomous driving. It operates in the frequency range of 24 GHz to 77 GHz and provides high-resolution images of the vehicle's surroundings. 毫米波雷达是汽车安全和自动驾驶领域的关键技术。

它在24 GHz至77 GHz的频率范围内工作，并提供车辆周围高分辨率的图像。

One basic principle of millimeter wave radar imaging is the use of electromagnetic waves to detect objects and create a detailed picture of the environment. These radar waves are emitted by the radar system and then bounce off objects in the vehicle's vicinity, such as other vehicles, pedestrians, or road obstacles. 毫米波雷达成像的一个基本原理是利用电磁波来探测物体，并创建环境的详细图像。

这些雷达波由雷达系统发射，然后反射在车辆附近的物体上，如其他车辆、行人或道路障碍物。

Another fundamental aspect of millimeter wave radar imaging is its ability to generate 3D images of the surrounding environment. This3D capability allows the radar system to not only detect the presenceof objects but also to accurately measure their distance and speed. In addition, the high resolution of the images enables the radar to distinguish between different types of objects, such as a car versus a pedestrian, and accurately identify their positions relative to the vehicle. 毫米波雷达成像的另一个基本方面是其能够生成周围环境的3D图像。

The advent of autonomous vehicles has revolutionized the transportation industry, offering a glimpse into a future where human intervention in driving is minimal. Autonomous vehicles, or selfdriving cars, are equipped with advanced technologies that enable them to navigate roads, avoid obstacles, and make decisions without the need for a human driver.At the core of these vehicles is a sophisticated combination of sensors, cameras, and radar systems that provide a 360degree view of the surroundings. These systems allow the car to detect and interpret its environment, identifying other vehicles, pedestrians, traffic signals, and road signs. The data collected is processed by powerful onboard computers that use algorithms to make realtime decisions.One of the key features of autonomous vehicles is their ability to communicate with each other and with the infrastructure around them. This VehicletoVehicle V2V and VehicletoInfrastructure V2I communication is facilitated by dedicated shortrange communication DSRC technology, which allows for the exchange of information such as speed, direction, and braking status.The selfdriving system also includes advanced mapping technology that provides a detailed and accurate representation of the road network. This is combined with realtime data from the vehicles sensors to create a comprehensive understanding of the vehicles position and the environment ahead.Safety is a paramount concern in the development of autonomous vehicles. These vehicles are designed with multiple layers of redundancy to ensure that if one system fails, others can take over. For example, if the primary sensor system fails, backup sensors can provide the necessary data for the vehicle to continue operating safely.Autonomous vehicles have the potential to significantly reduce traffic accidents caused by human error. They can also improve traffic flow and reduce congestion by optimizing routes and adjusting speeds to match traffic conditions. Furthermore, they can offer greater mobility to those who are unable to drive, such as the elderly or people with disabilities.As the technology continues to evolve, we can expect to see more autonomous vehicles on the roads. Companies like Tesla, Waymo, and Uber are already testing their selfdriving cars, and it is only a matter of time before they become a common sight in our cities and towns. The transition to a world of autonomous transportation will bring about a host of changes, but the promise of safer, more efficient, and more accessible transportation is an exciting prospect for the future.。

无人驾驶的好处和潜在危险英语作文全文共3篇示例，供读者参考篇1The Benefits and Potential Dangers of Self-Driving CarsAs technology continues to advance at a rapid pace, one of the most exciting and potentially transformative developments on the horizon is the advent of self-driving vehicles. While the idea of a car navigating roads and making complex decisions without human input may seem like science fiction, companies like Tesla, Google, Uber, and traditional automakers are pouring billions into research and development to make driverless cars a reality. As a student who will be entering the workforce in the next few years, I can't help but wonder how the emergence of autonomous vehicles could reshape the transportation landscape and what that might mean for my own life and future career prospects.On one hand, the potential benefits of self-driving cars are immense and could help solve some of society's most vexing issues related to transportation. The first and most obvious advantage is increased safety. Human error accounts for astaggering 94% of vehicle crashes, according to the National Highway Traffic Safety Administration. With robots at the wheel, factors like distracted driving, driving under the influence, fatigue, and poor decision-making would be eliminated from the equation. Not only could this save countless lives each year, but it could also reduce congestion caused by accidents andrans associated with emergency response.In addition to the safety benefits, widespread adoption of self-driving cars could dramatically increase mobility for people unable to drive due to age or disabilities. This could allow more elderly and disabled individuals to live independently and maintain their freedom for longer periods of time. It could also cut transportation costs significantly by allowing families to rely primarily on an affordable, self-driving ride service rather than owning a personal vehicle. Less need for private car ownership could lead to less vehicles on the road overall, creating more open space in urban areas currently occupied by parking lots and opening up possibilities for city redesign.Environmental benefits of driverless cars include the potential for increased fuel efficiency through optimal routing, fewer emissions from reduced traffic congestion, and the ability to implement alternative fuel sources easier in a standardizedfleet of self-driving cars. The economic impact could be massive as well, with estimates that autonomous vehicles could save the U.S. economy alone over 800 billion per year from increased productivity, reduced costs associated with traffic accidents, and more efficient use of travel time. A new industry and many new jobs would also be created to manufacture, service, and develop the software and technology behind self-driving cars.While the potential upsides of autonomous vehicles are undoubtedly attractive, they also present some very real and unsettling risks that must be carefully considered as the technology evolves. My biggest concern is the possibility of system failure, hacking, or other malicious attacks that could put passengers' safety in jeopardy. In 2015, researchers were able to successfully hack a Jeep Cherokee's controls while it was being driven, an alarming preview of the types of cyber threatsself-driving cars could face. With line of code connecting autonomous vehicles to the internet, the risk of fleets being compromised looms large. The consequences of such a breach could be catastrophic.There are also ethical quandaries and legal questions surrounding culpability in accidents involving self-driving cars. If an autonomous vehicle is involved in a fatal accident, who isliable - the passenger, automaker, software company that provided the driving intelligence? The lack of clear regulations and accountability could set up lengthy legal battles and sow confusion in the courts for decades to come. There are also concerns from labor unions that autonomous vehicles could eliminate millions of jobs for professional drivers, from long-haul truckers to taxi cab operators. While this could be offset by new jobs created in the autonomous vehicle industry, the transition could still be extremely disruptive for many workers and their families.On a societal level, some urban planners worry that driverless cars could paradoxically increase suburban sprawl by making long commutes more palatable, draining resources from city centers and diminishing the advantages of dense, walkable communities. There are also privacy concerns about the tracking data required for self-driving cars to safely navigate routes and the potential for that information to be abused by companies or government overreach.When I weigh all of these factors, I ultimately feel that the benefits of self-driving vehicles outweigh the potential risks and disadvantages, but only if the technology is implemented cautiously and with appropriate safeguards in place. Rigoroustesting, security measures, clear regulations, and a gradual rollout that allows society to adapt are all critical components that cannot be overlooked. Autonomous vehicles are an innovation that could dramatically improve quality of life, but we must take great care to address the dangers and ensure a safe and equitable transition.As a student looking ahead to embarking on a career in the coming years, I find the rise of self-driving cars both exhilarating and daunting. They could open up new professional opportunities for me in emerging fields like software engineering for autonomous systems or urban planning optimized for driverless transport. However, there is also the possibility that my own job prospects could be threatened by increasing automation and artificial intelligence displacing human workers. No matter which path lies ahead for me,self-driving cars will undoubtedly upend many assumptions about transportation, work, and everyday life that previous generations took for granted. My role will be to stay informed, consider the ethical implications, and prepare myself to help shape this new autonomous age in a way that maximizes its potential to better society while mitigating the dangers. It's sure to be a thrilling and unpredictable journey, and one that my generation will play a pivotal role in navigating.篇2The Benefits and Potential Dangers of Self-Driving CarsSelf-driving cars have been a topic of intense discussion and debate in recent years. As a university student studying computer science, I find this technology both fascinating and concerning. On one hand, autonomous vehicles could revolutionize transportation and vastly improve road safety. On the other, the risks involved with ceding control to artificial intelligence raise troubling ethical and practical questions. In this essay, I will examine the potential benefits of self-driving cars as well as the dangers we must be vigilant about.Perhaps the most compelling argument in favor ofself-driving vehicles is their potential to drastically reduce traffic accidents and fatalities. According to the World Health Organization, over 1.3 million people die in road crashes every year, with human error being a critical factor in over 90% of those accidents. By removing the fallible human element from the equation, autonomous cars could virtually eliminate crashes caused by drunk, distracted, or reckless driving. Their sensor systems and reaction times far surpass those of people. If adopted widely, self-driving tech could save millions of lives over time.Another major benefit would be increased mobility for those currently unable to drive due to age or disabilities. The elderly and visually impaired, among others, often suffer from lack of independence and social isolation due to their inability to operate vehicles safely. Self-driving cars would restore their freedom of movement and improve their quality of life immensely. This same advantage would extend to the broader public as well, leaving people free to use their commute time more productively or simply relax rather than dealing with the stress of driving in heavy traffic.On a societal level, widespread adoption of autonomous vehicles could reduce traffic congestion, air pollution, parking requirements, and overall transportation costs. With sophisticated sensors and vehicle-to-vehicle communication, self-driving cars could travel more efficiently by maintaining optimal speeds and safe distances between one another. Fewer traffic jams would mean less time idling in congestion and burning fuel unnecessarily. More efficient routing could cut travel times and ease strain on public infrastructure. If autonomous ride-sharing takes off, it could reduce the need for parking space as fewer personal vehicles would sit idle. Overall, the economic and environmental impacts could be tremendous.Those are just some of the potential upsides to autonomous driving tech. However, we cannot ignore the very real dangers and ethical minefields that come with ceding control to artificial intelligence systems. One major concern is cyber security - if self-driving cars can be hacked and their systems hijacked, the consequences could be disastrous. Entire fleets of autonomous vehicles could theoretically be turned into weaponized drone bombs with a few lines of malicious code. The software running these cars must be virtually unhackable to prevent such nightmare scenarios.Even if the systems are secure, the decision-making algorithms that control the cars' movements raise troubling ethical questions. In situations where a crash is unavoidable, how should the car's programming prioritize between protecting its passengers versus minimizing casualties outside the vehicle? Should it prioritize the lives of children over adults? High-profile individuals over ordinary citizens? There are no clear ethical guidelines for how to weigh these competing values. Programmers would be tasked with deciding whose lives to prioritize, basically playing a modern incarnation of the old "trolley problem" thought experiment.There are also complex legal questions surrounding liability in the case of an accident involving a self-driving car. Suppose an autonomous vehicle is involved in a fatal collision - who would be held responsible? The automaker? The software company? The sensor manufacturer? Resolving such issues could involve drawn-out legal battles with immense financial and ethical stakes. New legal and regulatory frameworks may need to be created specifically to deal with self-driving technology.On a personal level, I worry about the loss of autonomy involved with self-driving cars. As a driving enthusiast, I value the experience of being in control behind the wheel. There is an undeniable pleasure in the skill involved with operating a vehicle adeptly. Turning over that responsibility entirely to an impersonal machine feels like it could diminish a core aspect of human identity and agency. What if we grow overly dependent on automation to the point where key skills atrophy from disuse? There could be negative psychological impacts to becoming passive occupants disconnected from the acts of navigating and driving.Overall, while I'm in awe of the technical marvels ofself-driving vehicles, I can't fully embrace the technology until its myriad risks and dangers are addressed. The potential benefits interms of safety and efficiency are compelling, but not enough to abandon skepticism and ethical scrutiny. As the technology continues advancing, we must demand robust cybersecurity, transparent decision-making algorithms aligned with human values, equitable legal frameworks, and provisions to maintain key human skills and agency. Responsible development and trusted fail-safes are essential to public adoption. Self-driving cars could represent the next great transportation revolution - but only if we negotiate its uncertainties with clear eyes and level heads.篇3The Benefits and Potential Dangers of Self-Driving CarsAs technology continues to rapidly advance, one area that has seen tremendous progress is the development of self-driving vehicles. These autonomous cars, which can navigate roads and highways without human input, have the potential to revolutionize transportation as we know it. However, as with any new and disruptive technology, the rise of self-driving cars also brings with it a host of potential benefits and risks that must be carefully considered.On the positive side, proponents of self-driving cars argue that they could significantly reduce the number of accidents caused by human error, which accounts for a staggering 94% of all crashes according to the National Highway Traffic Safety Administration. With advanced sensors and sophisticated algorithms, autonomous vehicles can potentially react faster and more accurately than human drivers in various situations, such as sudden obstacles or hazardous weather conditions. By eliminating factors like distracted driving, fatigue, and impaired judgment, self-driving cars could potentially save thousands of lives each year.Furthermore, self-driving technology could provide increased mobility for those who are unable to drive themselves, including the elderly, people with disabilities, and those without a driver's license. This newfound independence could greatly improve their quality of life and allow them to participate more fully in society. Additionally, by reducing the need for individual car ownership, self-driving cars could potentially alleviate traffic congestion and parking shortages in urban areas, leading to a more efficient use of road infrastructure and a lower environmental impact.Another potential benefit of self-driving cars is increased productivity. With the ability to work, read, or relax during their commute, individuals could use their travel time more efficiently, potentially boosting overall productivity and reducing stress levels associated with driving in heavy traffic.However, despite these potential advantages, the widespread adoption of self-driving cars also raises significant concerns and challenges. One of the most pressing issues is the ethical dilemma of how these vehicles should be programmed to handle unavoidable accident situations. For instance, if a collision is imminent, should the car prioritize the safety of its occupants over pedestrians or other vehicles? Who should be responsible for making these complex ethical decisions, and how can we ensure that they are fair and consistent?Another concern is the potential job displacement that could result from the widespread adoption of self-driving vehicles. Millions of people are currently employed as professional drivers, including truck drivers, taxi drivers, and ride-share service providers. The transition to autonomous vehicles could potentially render many of these jobs obsolete, leading to significant economic disruption and the need for comprehensive retraining programs.Furthermore, the security and privacy implications ofself-driving cars cannot be overlooked. These vehicles rely heavily on complex software and interconnected systems, which could potentially be vulnerable to hacking or cyber attacks. Malicious actors could potentially gain control of a self-driving car, putting its occupants and others on the road at risk. Additionally, the vast amounts of data collected by these vehicles, including location information and travel patterns, raise privacy concerns and the potential for misuse or unauthorized access.Despite these challenges, many experts believe that the benefits of self-driving cars outweigh the potential risks, and that the technology will continue to advance and become more widely adopted in the coming years. However, it is crucial that policymakers, automakers, and technology companies work together to address the ethical, legal, and practical concerns surrounding autonomous vehicles.One potential solution could be the development of comprehensive regulations and guidelines to govern the design, testing, and deployment of self-driving cars. These regulations could establish clear standards for safety, cybersecurity, and ethical decision-making, while also addressing issues such asliability in the event of an accident involving an autonomous vehicle.Additionally, extensive public education and awareness campaigns could help alleviate concerns and foster greater acceptance of self-driving technology. By clearly communicating the potential benefits, as well as the measures being taken to mitigate risks, individuals may be more likely to embrace this transformative technology.Ultimately, the advent of self-driving cars represents both an exciting opportunity and a significant challenge. While the potential benefits, such as increased safety, mobility, and efficiency, are compelling, the potential risks and ethical dilemmas must be carefully navigated. It is up to all stakeholders – automakers, tech companies, policymakers, and the general public – to work together to ensure that the development and deployment of self-driving cars prioritizes public safety, ethical principles, and the greater good of society.As a student, I am both fascinated and cautiously optimistic about the future of self-driving cars. While I recognize the potential for increased convenience, productivity, and safety, I also believe that we must remain vigilant in addressing the potential dangers and ethical challenges that accompany thistransformative technology. By engaging in thoughtful dialogue, fostering public understanding, and developing responsible regulations, we can work towards a future where self-driving cars enhance our lives while upholding the highest standards of safety, ethics, and individual rights.。
