What is the difference between swing check valves
|
What is the difference between swing check valves and axial flow silent check valves?
At the most basic level, check valves are any valve that allows for fluid to flow in one direction and prevents backflow in the other. They are self-automated, using the pressure of the fluid to open and close rather than an operator. axial check valve and axial flow silent valves are the two most popular types of check valves. So, what is the difference between swing check valves and axial flow silent check valves? Specifically, in terms of operation and return on investment (ROI)?
A fairly basic type of valve, swing check valves are butterfly-style, meaning the disc — the part that blocks the fluid flow — opens and closes on a hinge or trunnion. Although these are ideal for some applications, swing check valves are being steadily phased out due to common recurring problems, such as turbulent flow and water hammer.
Axial Flow Silent Check Valves
Axial flow silent check valves are an updated design on swing check valves. The disc in the valve is held in place by a spring. This centers the movement of the disc, allowing for smoother fluid flow and responsive opening and closing without the sudden movements that cause water hammer.
Because axial flow silent check valves are more complex to design and manufacture, they usually come with a higher price tag than traditional swing check valves. Many plant managers do not understand how the low cost of ownership and long term benefits of these axial flow silent valves far outweigh the initial higher price. A ROI study with data spanning over 20 years proves this case.
The study, conducted at a utility facility, compared the costs of using swing check valves for 10 years, before a conversion to axial flow silent check valves, and the costs of using DFT® Inc. axial flow silent check valves for 10 years after installation. This study compared valve costs and overhead costs — including shipping, installation costs, and administrative costs — for two valve classes, 150# and 300#.
For the 150# valves, swing check valves cost an average of $1,467.12 each, while axial flow silent check valves cost an average of $4,812.99 each; per valve overhead was $1,000 for both swing and axial flow silent check valves. The swing check valves had to be replaced an average of 4.5 times a year, bringing their use cost to $11,102 annually — more than $111,000 over a decade.
After the conversion to DFT® Inc.’s axial flow silent valves, replacements dropped dramatically, from 4.5 times a year to once every 3.5 years. Despite the higher initial cost of the spring-assisted valves, their superior performance reduced annual maintenance costs to $1,660.85, or just over $16,600 for the decade; that’s an 85% reduction in overall operating cost.
The cost reduction in 300# check valves was even more significant. Before conversion, these valves resulted in $102,750 in costs over 10 years of use; in the 10 years since the installation of DFT® silent check valves, however, the company has not yet had to replace them.

Why You Should Replace Your Swing Check Valve With a Silent Check Valve
Used to restrict fluid flow to a certain direction, swing type check valve are employed in the vast majority of industrial processes. At DFT® Inc., we provide a wide range of check valves for use in diverse industrial applications. Our spring-assisted in-line check valves, for instance, are specifically designed to prevent water hammer by eliminating the risk of reverse flow. And, if sizing is done to account for flow rather than line size, these high-performance valves will operate reliably and efficiently for years, without the need for extensive maintenance.
The experts at DFT® often help clients assess their unique check valve requirements; our check valve sizing program allows us to easily determine required valve sizes before actual setup, eliminating the risk of design errors and delays. DFT® check valves can be installed in-line in any orientation; valve operation will not be hampered in any way by the specific orientation chosen, provided the flow direction is in line with the valve design (as indicated by an arrow on the valve casting).
However, for a downward flow, these check valves need to be modified slightly to support the additional weight of the disc and any static head that may be involved. While silent check valves can be employed in vertical piping or in installations requiring constant controllable pressure, swing valves should only be used in horizontal pipe runs, in which minor flow variations are expected.
When using swing check valves, users are afforded limited pressure control, as there is less control over valve opening and closing. Therefore, this type of valve is usually employed in less sensitive, large-scale pipelines carrying liquids, gases, or steam. To allow for enhanced performance, these swing check valves can be replaced by our GLC® Silent Check Valves or Excalibur® Silent Check Valves. These silent check valves have only one moving part and allow for greater flow variability than a conventional style swing check valve. Also, because the DFT Axial Flow Check Valves have so few moving components, they are more resistant to wear and tear and can maintain a longer lifespan.
However, the GLC® model is not considered a “dead-end” service valve. It is essential that the upstream, or seat end, of the valve be connected to the line until the pressure is relieved from the downstream end. The seat end of the valve must always remain bolted to the mating flange when the valve is exposed to downstream pressure in order to avoid possible blowout of the internals, as the retaining screws do not account for direct exposure to downstream pressure. In addition to eliminating water hammer, appropriately sized silent check valves can greatly improve system safety, protect critical system components like pumps, and improve overall system life while reducing maintenance costs.

Meet the human-friendly robot
Researchers have created a Industrial Robotic Manufacturer that they say could bring a softer touch to automation.
Dubbed Blue, the two-armed bot is designed to work alongside humans and be cheap enough not to break the bank. For now, it’s a research tool. But researchers at the University of California, Berkeley — who created Blue — say its human-friendly design and artificial intelligence capabilities could pave the way for household robots that help out with domestic tasks such as cleaning, folding laundry and even making coffee.
“We wanted to create a new robot that is right for the AI age rather than for the high-precision, sub-millimeter, factory automation age,” Pieter Abbeel, a professor of electrical engineering and computer science at Berkeley and the leader of the research team that built the robot, said in a written statement.
The robots Abbeel references are widely used in manufacturing, but they can be risky for humans who get in the way. Between 1992 and 2015, 61 Americans died from injuries sustained in robot-related accidents, according to the Center for Occupational Robotics Research of the National Institute for Occupational Safety and Health.
That’s doubly true for robots that use deep reinforcement learning, a technique in which machines try a task over and over again until they get it right. Mistakes made by a big, powerful industrial robot can be dangerous for human and machine alike. A robot that learns by trial and error needs a gentler touch — especially in households with children and pets.
How do you make a robot that performs useful household tasks without putting others at risk? Abbeel and his team designed Blue so that it responds to touch, varying the force it exerts according to the force exerted on it. In a video showcasing Blue’s abilities, the robot gives way immediately when nudged by a human.
Blue’s design is softer than those of some industrial bots. Its components are covered in curved plastic shells, with few sharp edges. Its arms, shaped roughly like a human’s, end in small claw-shaped grippers. A camera mounted between the arms like a tiny head allows the bot to take in its surroundings.
Blue isn’t the first sensitive robot. But with total manufacturing costs of less than $5,000, it may be one of the cheapest. Industrial robotic arms can cost tens or hundreds of thousands of dollars.
Right now, Blue can’t do too much on its own. When it folds a towel, arranges flowers in a vase and makes coffee in the video, it’s being piloted by a researcher using a virtual reality headset. And to keep costs down, it’s not as strong or precise as its industrial brethren. Selma ?abanovi?, an expert in human-robot interaction at Indiana University who wasn’t involved in the research, said the arm wasn't quite ready to take over your chores.

Singapore’s early-stage fund highlights four of tech’s most promising avenues
Artificial intelligence, self-driving vehicles, medical technologies and quantum computing are areas of focus for Singapore’s early stage, state-funded investor.
While those technologies are still in their nascent stages, they are becoming more interconnected and, as a result, having a cross-disciplinary understanding of them is fundamental for investors, according to Tong Hsien-Hui, head of venture investing at SGInnovate.Acr welding robots
“We like technologies that are inevitable,” Tong told CNBC in an interview on Tuesday, adding that investments in the so-called deep-tech space are an investment in the future.
“No one jumps into deep tech and says, ‘Hey, the technology is for here and now.’ Everyone jumps in and says, ‘I believe that this technology will be relevant and important five years from now’,” Tong said.
SGInnovate is funded wholly by the Singapore government but Tong declined to disclose the fund size. Its mandate is to invest in early-stage local, and some international, deep-tech start-ups. Unlike Temasek Holdings, which is the city-state’s investment arm, the checks that Tong and his team write are relatively small — on average, deals are worth between $350,000 and $1.5 million.
“That would be, basically, our comfort zone. We can do more, we can do less, depending on what the opportunity is,” he said.Artificial intelligence is becoming more important not just to Singapore, which has undergone rapid digitization in recent years, but to the entire Southeast Asia region, according to Tong.
Seeing AI’s potential value, investors around the world have been opening their checkbooks to start-ups. Venture capital funding of AI-related companies jumped 72% globally and hit a record $9.3 billion in 2018, a report from PwC and CB Insights said earlier this year.

Exemestane Prevents Breast Cancers in Postmenopaus
|
Exemestane Prevents Breast Cancers in Postmenopausal Women
A daily dose of the aromatase inhibitor exemestane dosage reduced invasive breast cancers by 65% in a placebo-controlled chemoprevention trial that enrolled 4,560 postmenopausal women considered at increased risk of the disease.
Pre-invasive breast cancers and precancerous lesions also were much less common at a median follow-up of 3 years in the study, which is expected to reopen a stalled conversation between women and their physicians regarding the risks and benefits of chemoprevention.
Two selective estrogen receptor modulator (SERM) drugs – tamoxifen and raloxifene (Evista) – are approved for breast cancer prevention, but they are little used for that purpose. Estimated tamoxifen use runs as low as 4% in high-risk women, who are thought to be deterred by rare but potentially serious side effects.
Exemestane (Aromasin) could become a third option for breast cancer prevention in postmenopausal women, Paul E. Goss, M.D., Ph.D., the lead author, said, announcing the results on behalf of the MAP.3 (Mammary Prevention.3 trial) investigators at the annual meeting of the American Society of Clinical Oncology.
"Because of the significant reduction of breast cancer and the excellent safety profile, exemestane has the potential for wider-scale implementation than the selective estrogen modulators in our view," declared Dr. Goss, a professor of medicine at Harvard Medical School and Massachusetts General Hospital in Boston.
Women had to be age 35 or older and postmenopausal with at least one specified risk factor to enter the trial, he noted. Age greater than or equal to 60 years by itself was considered a risk factor, as were a five-year Gail risk score greater than 1.66%, prior atypical ductal or lobular hyperplasia or lobular carcinoma in situ, or prior ductal carcinoma in situ with prior mastectomy.

What is exemestane?
|
1. What is exemestane?
exemestane bodybuilding dosage is a drug used to treat breast cancer in women who have gone through the menopause. You may also hear it called Aromasin, which is its best-known brand name. There are a number of other brands of exemestane, all of which contain the same dose of the drug. Men with breast cancer may be given exemestane, although another drug called tamoxifen is more commonly used.
2. How does exemestane work?
Exemestane works by reducing the amount of oestrogen made in the body. Some breast cancers are stimulated to grow by the hormone oestrogen. These are known as oestrogen receptor positive or ER+ breast cancers.Exemestane belongs to a group of drugs called aromatase inhibitors.
3. Who it is suitable for
Exemestane is suitable for women who have been through the menopause and whose breast cancer is oestrogen receptor positive.Sometimes exemestane is given alongside a drug called goserelin (Zoladex) to women who haven’t yet been through the menopause. If your cancer is hormone receptor negative, then exemestane will not be of any benefit.
4. Side effects of exemestane
Find out more about the side effects of exemestane.
5. When exemestane is given
Exemestane is usually given after surgery to reduce the risk of breast cancer coming back or spreading.If you’re having chemotherapy or radiotherapy, your specialist will tell you when it’s best to start exemestane.
Occasionally, exemestane may be used as the first treatment for breast cancer, for example when surgery isn’t appropriate or needs to be delayed. It’s sometimes given before surgery to shrink a large breast cancer.
Exemestane can also be used to treat breast cancer that has come back (recurrence). It can also be given to treat breast cancer that has spread to another part of the body (secondary breast cancer), when it’s often given alongside another drug.
6. How long will I have to take it?
This will depend on your individual circumstances, but exemestane is usually taken for five to ten years.Some people start taking exemestane after a few years of taking the hormone therapy drug tamoxifen. If you’re taking exemestane to treat breast cancer that has come back or spread to another part of the body, you’ll usually take it for as long as it’s keeping the cancer under control.

Exemestane (Aromasin)
|
Exemestane (Aromasin)
Many breast cancers are stimulated to grow by the female sex hormones oestrogen and progesterone. These breast cancers are called hormone sensitive or hormone receptor positive. Blocking the effects of these hormones can treat breast cancer.
In women who have had their menopause, oestrogen is mainly produced by changing androgens (sex hormones produced by the adrenal glands) into oestrogens. This process is called aromatisation and happens mainly in the fatty tissues, muscle and the skin. It needs a particular enzyme called aromatase.
exemestane powder blocks the process of aromatisation. So it lowers the amount of oestrogen in the body. In early breast cancer, taking exemestane can help to stop breast cancer coming back. In advanced breast cancer, the cancer cells may grow more slowly or stop growing completely.

How strangers can hack the phone in your pocket

How strangers can hack the phone in your pocket
In today’s world, there’s really only two types of companies or two types of people which are those who have been hacked and realize it and those who have been hacked and haven’t.” That’s what mobile security expert John Hering tells 60 Minutes correspondent Sharyn Alfonsi about the danger of cellphone hacking on this week’s broadcast.
While most people worry about their computers getting hacked, Hering explains that phones are vulnerable, too. To prove his point, Hering assembled a group of ace hackers at a Las Vegas hotel where the 60 Minutes team was staying. In the video above, 60 Minutes Overtime explores what happened.
The hackers Hering gathered, all of whom try to identify security weak spots in order to protect the public, were in Las Vegas for Defcon, a conference that draws roughly 20,000 hackers each year to trade secrets and share information.
60 Minutes producer Howard Rosenberg asked them to share some of their tricks. “We worked on this story for well over two years and during that period of time, we were constantly challenging the hackers to take it to another level and to demonstrate for us what they claimed,” he tells 60 Minutes Overtime editor Ann Silvio. “They say, ‘Everything is hackable.’ And we kept saying to them, ‘OK, prove it.’”
And prove it they did. One hacker, Jon Oberheide, showed 60 Minutes an app he created that looks legitimate but allows him to take control of a phone and suck out its information. He demonstrated for Alfonsi how he could instantly pull up her contacts, recent purchases and text messages. “It’s almost uncanny to watch how creative these folks are,” says Rosenberg.
Another hacker, Adam Laurie, uses radio frequency identification to hack phones. “So the way this hack worked -- he didn’t need my phone number,” Alfonsi explains. “All he had to do was physically touch my phone.” He demonstrated by brushing by her in the lobby of her hotel. When he did, he used a special hand-held device to push a credential across to her phone so it trusted his Bluetooth and actually dialed Laurie, allowing him to listen in on anything discussed in the room with Alfonsi’s phone.https://www.ttspy.com/hack-phone-contacts.html

All the reasons why cybercriminals want to hack yo

All the reasons why cybercriminals want to hack your phone
When people think of hacking, most imagine desktop computers, laptops, or perhaps even security cameras. However, in recent years, cybercriminals have expanded their repertoire to include smartphones, too. Here are 10 reasons why they may be looking to hack your phone.
1. To infect it with malware
Many smartphone users assume they can stay safe from malware and other threats by installing antivirus apps on their phones and being extra careful about the websites they visit. They typically don’t expect their phones to have malware out of the box. However, researchers showed that’s what happened with more than three dozen Android models, typically from lesser-known brands.
The phones had Trojan malware installed on them before they reached users, and the culprit appeared to be a software vendor in Shanghai that was a shared reseller for a brand of antivirus software. Although it’s not clear what the hackers wanted to do after infecting the phones, the malware was particularly hard to remove. Often, it involved fully reinstalling the operating system.
2. To eavesdrop on calls
People use their phones to speak to loved ones, discuss business plans, talk about their travels—all manner of personal, intimate content. So, it’s not surprising that criminals would want to break in and listen, whether to case a target or simply for voyeuristic pleasure. But how do they do it?
There’s a flaw in US cellular exchange, the vulnerability known as SS7, which allows hackers to listen to calls, read texts, and see users’ locations after learning their phone numbers. Even though US agencies know about the issue, they haven’t taken decisive action to fix it, leaving Americans’ phone privacy at risk.
3. To steal money
Ransomware attacks cause headaches for computer users by making the affected machines lock up or holding files hostage until people pay the ransom to restore access. Even then, paying doesn’t guarantee a return to proper functionality. Ransomware doesn’t only affect computers, though. There’s a recent trend of mobile ransomware, which often originates from malicious, third-party apps.
In one example, a third-party app promised to optimize the Android system but actually tricked people into transferring $1,000 from their PayPal accounts. The login process was legitimate, so it wasn’t a phishing attempt. However, once people logged in, a Trojan automated the PayPal transfer.
4. To blackmail people
The crime of blackmail isn’t new, but threat actors recognize that the small computer in people’s pockets and purses likely has more personal information stored in it than a desktop or laptop. And they are able to first cut people off from accessing their phones before then threatening to leak the information they find.
Criminals may start the hack after obtaining some personal information from a victim that available on the black market due to a previous, unrelated breach. They then use that information to contact the victim’s phone company and pose as the user, saying that they want to transfer the number to a new phone. Phone companies often provide such services and can automatically transfer information, including phone numbers, to a new device. The trouble is that in this case, the old phone still works but it’s useless to the person who owns it.
After hackers take over a phone in this way, the stage is set for more serious crimes—blackmail among them. If a person had essential numbers in their phone not backed up elsewhere, they could easily feel pressured to cave into hackers’ demands to avoid worse consequences.https://www.ttspy.com/hack-phone-contacts.html

If you've been hacked, don't count on the police for help
An email pops up in your inbox and your eyes widen. A stranger claims to have video footage of you watching porn and asks for $1,000.There's outrage and embarrassment. You reach for your phone. But then you wonder, "Who do I even call?" Unfortunately, the answer to that question is complicated.
As it turns out, even law enforcement officials can't agree. The FBI and your local police both suggest that you should call them. But experts warn that in many cases, neither agency will be able to help, especially if the criminal is asking for so little money.
This dynamic underscores why these kinds of hacks -- and yes, the porn scam really happened -- are starting to proliferate. There's no clear answer on who to call. And from law enforcement's perspective, many of these crimes are too small to be worth prosecuting. It's no surprise that cyberattacks have run rampant across the web, as thieves online find ways to steal credit card information from millions of people without leaving their homes.
"If the people doing it keep the dollar amounts small enough that no individual police department is going to be motivated enough to prosecute, you can collect a lot of money from a lot of people all around the world," said Adam Bookbinder, the former chief of the US Attorney's cybercrime unit in the district of Massachusetts.Sometimes these crimes don't even involve a hack. An email scheme in which scammers spammed inboxes threatening to blackmail victims, without any evidence, netted $28,000 over two months, researchers from cybersecurity company Digital Shadows found.
But unless it's a public concern, there's a good chance no one will handle it, said Bookbinder, who's now a cybersecurity and privacy team member with the Holland & Knight law firm.https://www.ttspy.com/hack-phone-contacts.html

SOFT ROBOTIC ARM ALLOWS SCIENTISTS TO EXPLORE DELICATE MARINE LIFE AT GREAT DEPTHS
Professor David F. Gruber (GC/Baruch, Biology), a marine biologist who previously helped develop an ‘origami’ robotic claw to study jellyfish, is part of a research team that unveiled a new invention this week: a soft China Robotics Manufacturer designed for use in the deep sea.
Like the origami claw, the soft robotic arm is intended to help scientists study delicate organisms that can be harmed — or even destroyed — when handled by traditional means, which until recently have been mostly limited to industrial robotic arms, claws, and suction samplers.
The soft robotic arm can be operated below 150 meters, beyond the range of SCUBA divers. Scientists will operate it remotely using a wearable glove. A study describing the first test of the arm, conducted from a submarine in Brazil, appeared last week in Nature’s Scientific Reports. Gruber served as the biologist on the team. The lead author was Brennan T. Phillips of the University of Rhode Island.
The robotic arm is already in use, Gruber said. “The project started with ‘Squishy Robot Fingers’ and has since evolved into this glove-operated ‘Squishy Robot Arm,’” he said. “The intention is add something as agile and soft as human arms to a submarine, allowing a marine biologist to delicately interact with deep-sea marine life.”
The deep sea is the least explored biome on the planet, the authors note in the study. “Humans have only been exploring the deep sea for several decades,” Gruber said. “But in that short time we have learned that it is just as fragile, or more so, than shallow systems like coral reefs. Some marine creatures are estimated to be up to 18,000 years old and we want to examine them with utmost care.”
Gruber hopes that scientists will ultimately be able to set up sub-sea laboratories and perform similar experiments, using the squishy robot arms, to those that can be conducted in land-based laboratories. With his co-researchers, he is continuing to work on projects that demonstrate how technology can connect us more deeply — and empathetically — to life in the deep sea.
“We are planning to apply these new technologies to look at a diverse suite of biological aspects of deep-sea marine life, such as aging,” Gruber said. “It is very interesting to us how some deep-sea marine life can live for thousands of years. In the future, we aim to use these novel robotic devices to perform in-situ studies of deep-marine life that ultimately leaves them unharmed.”

VIDEO: SENSATION OF MOVEMENT RECREATED IN AMPUTEES’ ROBOTIC ARMS
When it comes to moving your limbs, you don’t need to see to believe. Intuitively, you know where your limbs are, as well as the positions they’re making.
This kind of awareness, called kinesthesia, is missing from prosthetic limbs—especially advanced, motorized ones. But a new study published in Science Translational Medicine lays out how a sense of self can be extended to prostheses, through cleverly crafted illusions.Robotic Manufacturer
“By restoring the intuitive feeling of limb movement—the sensation of opening and closing your hand—we are able to blur the lines between what the patients' brains perceived as 'self' versus 'machine',” said Paul Marasco, director of the Cleveland Clinic’s Laboratory for Bionic Integration, in a statement.
How can scientists restore intuitive feeling to a missing limb? A well-placed buzz. In able-bodied people, scientists have long documented that vibrating limb tendons create the illusion of moving or rotating the limb. One 1977 study found that the illusion is so powerful, people can be tricked into thinking that their wrists are bent at impossible angles.
To find out whether similar vibrations would work with artificial limbs, Marasco’s team partnered with six amputees who also had undergone surgery to rewire their amputated arms’ remaining nerves. This procedure, which directs these nerves to nearby muscles, lets the patients intuitively control robotic arms.
First, researchers used a hand-held tool to vibrate the areas innervated by the missing limbs’ nerves. At the same time, they asked the patients to mimic with their remaining hand the gesture they felt their missing hand was making. To the researchers’ surprise, the patients reported feeling a total of 22 different gestures in their missing hands—all illusions created with vibrations.
“We thought that if it worked like it did in an able-bodied person, we’d just get one or two joints; we’d get a wrist—something basic,” Marasco said in an interview with Gizmodo. “But what we found were these complex, multi-digit synergies where the whole hand is moving and they know where their fingers are going and what they’re doing, and they’re adopting these really interesting grip conformations. We were totally floored.”
In later experiments with three of the patients, Marasco’s team showed that these illusions could act as feedback cues. Sensors above the patients’ rewired skin and muscles detected when the missing limb nerves fired, triggering movement of the robotic arm. What’s more, the researchers built a module that could vibrate the rewired patches of skin and muscle in specific patterns, depending on the gestures the robotic arm was making.
Within minutes, the three patients improved their control over the robotic arm—and reported feeling a greater sense of agency over their robotic limbs, as well.

Smaller, smarter, softer robotic arm for endoscopic surgery
Flexible endoscopes can snake through narrow passages to treat difficult to reach areas of the body. However, once they arrive at their target, these devices rely on rigid surgical tools to manipulate or remove tissue. These tools offer surgeons reduced dexterity and sensing, limiting the current therapeutic capabilities of the endoscope.
Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a hybrid rigid-soft robotic arm for endoscopes with integrated sensing, flexibility, and multiple degrees of freedom. This arm — built using a manufacturing paradigm based on pop-up fabrication and soft lithography — lies flat on an endoscope until it arrives at the desired spot, then pops up to assist in surgical procedures
Soft robots are so promising for surgical applications because they can match the stiffness of the body, meaning they won’t accidentally puncture or tear tissue. However, at small scales, soft materials cannot generate enough force to perform surgical tasks.Industrial Robotic Arm
“At the millimeter scale, a soft device becomes so soft that it can’t damage tissue but it also can’t manipulate the tissue in any meaningful way,” said Tommaso Ranzani, a postdoctoral fellow at SEAS and the Wyss Institute and coauthor of the paper. “That limits the application of soft microsystems for performing therapy. The question is, how can we develop soft robots that are still able to generate the necessary forces without compromising safety.”
Inspired by biology, the team developed a hybrid model that used a rigid skeleton surrounded by soft materials. The manufacturing method drew on previous work in origami-inspired, pop-up fabrication, developed by Robert Wood, the Charles River Professor of Engineering and Applied Sciences.
Wood coauthored the paper and is a Core Faculty Member of the Wyss Institute.
Previous pop-up manufacturing techniques — such as those used with the Robobees — rely on actuation methods that require high voltages or temperatures to operate, something that wouldn’t be safe in a surgical tool directly manipulating biological tissues and organs.

Robotic arms, likely to replace humans at manufacturer-employers, featured at WESTEC 2017
The future of manufacturing — which looks a lot more robotic and a lot less human — is on display as WESTEC 2017 kicked off its three-day run at Los Angeles Convention Center on Tuesday.
The annual trade show highlights some of the latest technologies in manufacturing, leaving little doubt that automation is not the coming king, it’s the king that is here.
At the Lyndex Nikken booth, a robotic arm deftly retrieved a cylindrical metal part and moved it from one machine to another. Its movements were quick and precise.Industrial Robotic Arm
“What you’re looking at is our presentation area where the robot will pick up the piece and load it into the main spindle of the turning center,” said Randy Peacock, a senior engineering specialist with the Mundelein, Illinois-based tech firm. “In the second operation, it will load it into one of our pallet chucks. And then the robot will take the part and load it into our rotary cable site.”In layman’s terms that equates to efficiency, the kind of efficiency that has increasingly displaced blue-collar workers throughout the U.S. A report released earlier this year from the Los Angeles County Economic Development Corp. shows that California lost 181,400 manufacturing jobs from 2007 to 2016.
And there’s another ripple effect from all of this evolving technology.“Unfortunately, it’s getting harder to find people with the right skills in manufacturing,” Peacock said. “But more and more these days, businesses are going to automation. You can have four machines and just have one person tend all four machines.”The Manufacturing Institute and DeLoitte reported last year that the skills gap is widening in manufacturing. Some 3.4 million manufacturing jobs likely will be needed during the next decade, the report said, but 60 percent of those positions probably will remain unfilled because of the talent shortage.
Across the way at WESTEC, Irvine-based Universal Robots displayed its own robotic arm with a hand-held controller that allowed visitors to take a shot at operating the device.
“The objective is to get people familiar with programming robots and to understand that it’s no longer as difficult as it used to be,” said Dylan Shanahan, a technical support engineer with the company. “It’s actually become a lot simpler to get it into the hands of operators.”

Researchers help paralyzed man regain sense of touch through a robotic arm
A team of researchers working with Sliman Bensmaia, associate professor of organismal biology and anatomy at the University of Chicago, and led by Robert Gaunt, assistant professor of physical medicine and rehabilitation at the University of Pittsburgh, developed a brain computer interface that was surgically implanted in 28-year-old Nathan Copeland. The interface is connected to a China Industrial Robotic Arm that transmits sensory feedback through electrodes implanted in areas of the brain responsible for hand movement and touch.
Copeland was paralyzed from the chest down in a car accident in 2004, unable to feel or move his lower arms and legs. In a study published today in Science Translational Medicine, the researches demonstrate how he is now able to distinguish between touches on individual fingers and the palm of the robotic arm with input from the BCI.
“I can feel just about every finger—it’s a really weird sensation,” Copeland said in a news release from Pitt and the University of Pittsburgh Medical Center. “Sometimes it feels electrical and sometimes its pressure, but for the most part, I can tell most of the fingers with definite precision. It feels like my fingers are getting touched or pushed.”
The system incorporates years of research by Bensmaia describing how the nervous system interprets sensory feedback as we touch or grasp objects, move our limbs and run our fingers along textured surfaces. In a series of experiments with monkeys, whose sensory systems closely resemble those of humans, Bensmaia identified patterns of neural activity that occur naturally as the animals manipulate objects, and successfully recreated those patterns by directly stimulating the nervous system with electrical signals.
