IWARD nursebot looks to clean hospitals, fend off intruders
We all know security gets a little heavy eyed when the wee hours of the morning roll around, and we highly doubt the janitorial staff is humming along at maximum efficiency when the residents are snoozing away, so implementing a robot to tackle both tasks seems quite practical. The IWARD project hopes to develop a "nursebot" that wears several hats, and can handle cleaning up spills, utilizing face and voice recognition technology to "communicate with patients and spot unauthorized visitors," and even working in "swarms" to distribute tasks between the robotic crew. Researchers are aiming to have a three bot prototype ready to rock by 2010, and want to integrate sensors and camera to avoid collisions whilst "traveling along high-speed lanes in the hospital corridors." Better steer grandma's wheelchair clear of the robotic raceway, eh?[Via TechieDiva]
Kodak envisions edible RFID tags for medical purposes, light snacks
If you're not down with wearing, handling, or implanting RFID chips on (or in) human beings, we presume you're fairly skeptical about consuming one. A recent patent application filed by Kodak envisions an edible RFID wafer that would ideally be used to monitor various aspects of a patient's health. The digestible tag would be covered in a substance that would slow the dissolving process enough to view certain aspects of one's innards, and furthermore, these tags could be surgically implanted into knees and joints in order to alert doctors when additional work should be performed. The tags could even be integrated into medicines in order to more accurately witness whether a rebellious patient has indeed swallowed his or her pills. So before you cry foul on voluntarily ingesting a (hopefully) dissolving RFID tag, just think of all the medical breakthroughs this could lead to -- or how traceable you'd eternally be if your gastric acid is weaker than usual.[Via NewScientistTech, thanks Matt]
Eli Lilly offering up undercover insulin pen to US
There's already a bevy of devices out there designed to keep track and manage one's diabetes and glucose levels, but Eli Lilly's innocuous pen-like injector looks to make the process of taking insulin a bit less invasive. The Huma-Pen Memoir resembles your average ink pen and shouldn't look too out of place holding it down in your tee's front pocket, but whenever you need a shot of insulin, it conveniently turns into an injector thanks to the hidden hypodermic needle encased within. The device also "allows the user to dial the amount of insulin they need to take," and keeps the dosage, date, and time of the previous 16 shots in order to keep diabetics from overdosing. Users should be able to utilize the same pen for "around three years," and after a needle is used, another is inserted and ready to go at the owners request. A few lucky participants have already received their pen here in the US, and while this nifty invention has been available across Europe for some time now, it will officially hit American retail shelves next week for around $45.[Via MedGadget]
WVU's Punchstat system intelligently halts boxing matches
The state of West Virginia seems to be on the "get fit" warpath, as not only did the public school system decide to expand and renew the Dance Dance Revolution program to get youngsters a-movin', but now WVU has developed a system that allows boxers to give it a go without, um, perishing. The Punchstat analysis system is a ringside computerized tool that is being honed to provide a realistic and objective method of determining when a boxing match should be halted. Researchers in Morgantown have performed a "computer-assisted video analysis" to compare a trio of professional matches where one of them led to a fighter's death; these results were further compared with over 4,000 other bouts previously scored with Punchstat, and it was stated that a "significant differences" were seen in fights that led to death. Most notably, fighters that died due to boxing faced around 23 punches per round (compared to the average of 9.4), and more "power punches" were withstood as well. But before scientists can accurately implement a "danger meter" of sorts into pay-per-view matchups, some critics insinuate that factors such as "fighter strength and the effects of the punches that connect" need to be considered before it can be entirely reliable, and it's even suggested that a tried and true accelerometer be installed on a fighter to calculate the force of a blow. Still, we're down with beating someone to a pulp for sport if everyone leaves without a life-threatening injury, but we'll probably take the pansy's way out and stick with Wii Boxing to carve our calories.[Via Physorg]
Bionic armed woman regains sense of touch
Although Matsushita and Activelink have rolled out a rehabilitating robotic suit aimed at giving handicapped individuals their ability to maneuver their own body parts once again, it appears that Claudia Mitchell has regained her sense of movement using a slightly different apparatus. Touted as wearing the "world's first" bionic arm controlled by thought alone, she now has the ability to carry out simple, albeit quite critical tasks again such as cutting up food. Doctors have re-routed the nerve endings in her arm to "a patch of skin on her chest," essentially enabling her prosthetic arm to respond to her thoughts concerning movement. Furthermore, a recent study of her wrist, hand, and elbow functions revealed that she could perform tasks "four times quicker than with a conventional prosthesis," and the team hopes to install "touch sensors" on the artificial hand in order to allow for tactile feedback in the future. Claudia seems to be understandably thrilled with the results thus far, as it even allows her to accomplish tasks such as putting on makeup and feeding herself -- but we're slightly disappointed that she apparently hasn't given a round of Wii Sports a go to build up those oh-so-crucial hand-eye coordination skills, but we're sure that challenge is just around the bend.[Via Digg]
Researchers craft microscale robotic hand for surgeries
It's no surprise that humans are doing less and less of the dirty work while they simply control robotic creatures that are actually doing the internal repairs, but a UCLA researcher has devised a ridiculously tiny "microhand" to handle even the smallest surgery-related tasks. The hand, which is said to be a "feat of microscale mechanical systems (MEMS)," measures just one millimeter across when closed into a fist, features four "fingers" made of six silicon wafers each, and touts four gas-powered balloons acting as the muscles at the wafers' joints. As you may expect, the gas lines that run to the balloons inflate and deflate the joints, causing the fingers to grasp and release as needed. The primary purpose is to eventually use the technology in new forms of "minimally invasive surgery," and although the microhand is likely years away from practical use, they're already in cahoots with robotic firm to develop a "slightly larger" rendition with an onboard camera for live action video feeds.[Via MedGadget]
Paper checks out of hospital, ePrescription takes its place
Seems as though paper has found its way into another battle -- the National ePrescribing Patient Safety Initiative wants to replace our old tree-based friend with a presumably much safer Web-based system. Rather than continually risking the lives of millions of people by making pharmacists decipher doctors' illegible handwriting, prescriptions will are entered into a website, hopefully leaving less room for harmful and fatal errors. It's amazing that only "one fifth of U.S. doctors" use this kind of electronic system; by now you would think the robots that have invaded hospitals would be the ones doling out the happy pills, but we guess that's a battle left for another day. On the plus side, hackers will now have endless access to the uppers they need for monitoring their botnets around the clock.
Sharp offers up PN-655RU and PN-655RUP 65-inch portrait mode LCDs
If you make ends meet by checking out digital X-rays each day, or you just suffer from an awkward obsession with watching 16:9 material in a vertical orientation, Sharp is offering up a duo of LCDs specifically for you. Taking its highly-regarded PN-655U and PN-655UP and designing them for portrait mode use, the 65-inch PN-655RU / PN-655RUP displays both feature 1,920 x 1,080 resolution, cold-cathode fluorescent backlight, 170-degree viewing angle, 400 cd/m2 brightness, dual 10-watt speaker terminals, a sleek, all black frame, and weigh in at a whopping 145.5-pounds. Although both displays are designed for the "rugged" hospital wall, the PN-655RUP adds a protective acrylic overlay for an additional layer of protection. Of course, owning a high-end display that looks more like a mirror and less like a TV demands quite a premium, as the PN-655RU will set you back about a Mercedes C230 $29,995, while the PN-655RUP demands an even more shocking $32,995.
EEG signatures are the new fingerprint scans
If you think (er, know) that fingerprint scanners just aren't up to snuff with your strict demands, a team of European scientists are developing a novel replacement for biometric security. Dimitrios Tzovaras and his colleagues at the Center for Research and Technology Hellas in Greece have established a system which relies on measured activity in the brain to form a security protocol that's "difficult to forge." Since electroencephalography (EEG) measurements are unique for every person, users begin by having their brain activity recorded and analyzed, producing an "EEG signature" which can then be used to allow or deny entry into buildings, data centers, or other top secret locales. The catch is that employees would be forced to walk around with a wired helmet on their noggin, which could "potentially chang the ambiance of the workplace" according to a researcher at the University of Cambridge. Notably, the method is just one of the security layers that are being scrutinized as a part of the Human Monitoring and Authentication using Biodynamic Indicators and Behavioral Analysis (HUMABIO) project going on in Europe, which aims to "combine several different biometrics to create a more efficient and secure overall system." Of course, there's still some kinks to be worked out, especially considering that brain patterns are extremely dependent on "alertness," and we seriously hope they develop a less invasive (and gaudy) alternative to forcing blokes to rock oddly-shaped headgear as a part of their job.
da Vinci robot creators being sued by Caltech
It's no secret that doctors ought to have a good bit of insurance on their side due to the flurry of medical malpractice (and similar) lawsuits that hit hospitals and surgeons everyday, but you know things are rough when robotic MDs get taken to court as well. Intuitive Surgical Inc., the creators of the da Vinci system for robotic surgery, has been sued by the California Institute of Technology, which claims that the system "infringes four patents held by the university." Obviously, Intuitive's CEO called the suit "outrageous and without merit," but the Pasadena school is nevertheless "seeking an injunction" and repayment for "damages." What's notable about the case, however, is where it was filed, as Tyler, Texas is quite a long ways from both institutions, but attorney's in the know have called the Lonestar State "a haven for patent pirates." Of course, there are rulings out there that are finally leaning the way of the tech firms at hand, suggesting that "obvious patent laws" should be relaxed somewhat, but it seems that even this probably won't mess with Texas. Nevertheless, let's just hope one of those lawyers doesn't end up under a (disgruntled) da Vinci knife one day.[Via RobotGossip]
Diminutive cable holds promise in medical, solar realms
We tend to prefer our electronics to be as far from invasive as possible, and that definitely includes cabling. While we'd take wireless over the corded approach any day, tethered applications still have their place, and a diminutive new cable is showing bigtime promise in a few prominent fields. A research team has developed a cable that resembles that of an old fashioned coaxial strand, yet it's reportedly "much thinner than a human hair" and can transmit visible light. By constructing a cable about 300-nanometers wide which houses an inner wire of carbon surrounded by an insulator and an outer wire of aluminum, visible light can pass through, paving the way for its use in highly efficient solar energy cells, or furthermore, "miniature electrical circuitry and microscopic light-based switching devices for optical computing." Researchers even suggest that it could be used in retinal implants or "detecting single molecules of pathogens in the body." We're not yet sure just how potent or powerful these itty bitty cables can be, but judging by size alone, we're halfway sold already.
Shocking study reveals that activity in gaming fights obesity
Providing a mighty blow to both "research studies" and the value of Ph.D degrees everywhere, the latest rubbish information to come flowing from the Mayo Clinic's research lab is as close to an insult to intelligence as you can get. While it may have been somewhat understood that television can act as a painkiller for children, and that wireless headsets actually don't improve driving safety, this obviousness of this one takes the literal cake. The study, which is proclaimed as the "first to scientifically measure the energy spent playing video games," proved that sitting around while gaming burned the same amount of energy as kicking back and watching the tube, but when engaged in a "camera-based activity" (Eye Toy?), the "energy expenditure tripled." It was also shown that walking on a treadmill while gaming it up also tripled the energy burned, but it showed a "fivefold increase for the mildly obese group" of participants. While these results may be miles away from shocking, the most depressing aspect of the entire study was the conclusion that the results were so awe-inspiring that "they warrant further studies in randomized trials." Now, who's paying for this hoopla again?[Thanks, Mike]
LipoSonix aiming for non-invasive body sculpting
We're sure there's quite a few of you out there that have already vowed to make good use of that Nike+iPod kit you received this holiday season in order to shape up in 2007, but for those who just don't have the time (or adequate willpower), LipoSonix could help you fool everyone into thinking you actually kept your resolution. While liposuction has become frighteningly common here in the States, a Seattle-based medical device company is hoping to give folks a "less invasive" alternative to the messy methods currently used. Preferring the term "body sculpting," the company claims that its technology "works by focusing high-intensity ultrasound through the skin into precise locations within subcutaneous adipose tissue, which permanently disrupts the adipocytes without damaging the epidermis, dermis, or underlying tissues and organs." In short, a specially crafted ultrasound transducer can purportedly eliminate unwanted tissue quickly, causing "minimal downtime and bruising" to patients, and hopefully costing less than procedures done today. Although we can't promise this (admittedly bizarre) technology will be available by year's end, initial clinical testing has reportedly been quite successful, but until a few more guinea pigs have survived for an extended period of time, we'll be sticking with the tried and true "working out" method.
Chemists craft molecular keypad lock
While the folks behind the AACS could probably use a few pointers about constructing a sufficient lock of their own, a group of scientists at the Weizmann Institute of Science in Rehovat, Israel have crafted a molecule-sized "keypad lock" that "only activates when exposed to the correct password, a sequence of chemicals and light." Organic chemist Abraham Shanzer and his colleagues suggest that their invention could "lead to a new level of safeguards for secret information," but we tend think the infamous hackers of the world would inevitably crack the code. Nevertheless, the molecule -- dubbed FLIP -- houses a core linker that mimics a bacterial compound that binds to iron, and attached to it are two molecules that respectively can glow either blue or green. Using three "buttons," which just so happen to be an acidic molecule, an alkaline compound, and ultraviolet light, the lock can be "opened" if given the right sequence of chemicals and light, and there's a grand total of two noticeable results possible. Interestingly, the researchers have insinuated that their creation could be used to recognize "when certain sequences of chemicals (like harmful toxins) are released in the body," but we haven't heard a 10-4 from the US Army just yet.[Via Yahoo, thanks, Antonio H.]
Battery-free pacemaker on the horizon
Having one surgery is plenty, and having some foreign object implanted in your being is really pushing things, but knowing you're going to be under the knife every ten years or so to get a new battery is just absurd. Thankfully, a group of researchers in the UK feel the same way, and are well on their way to developing a battery-free pacemaker. Reportedly, the device would use a microgenerator producing electricity every time the patient moves, effectively eliminating the need for an internal battery. The cost of the £1 million ($1.96 million) project is being shared by the Department of Trade and Industry and private companies, one being Zarlink Semiconductor who has a large role in the device's development. Other teams around the globe are also seeking to create such a unit, with ideas spanning from tiny generators that receive power from heat right onto "biological pacemakers" that would correct heart problems without the need for a mechanical device. While there's no estimate as to when these gizmos will even hit the testing and approval phase, it seems that things are moving along quite well, but we have to stop and wonder how well a pacemaker powered by motion will function when you, well, cease moving.[Via MedGadget]
Sony's PDW-70MD XDCAM HD recorder gets official
We'll admit, we too noticed the stark irony in Sony -- the firm at least somewhat responsible for recalling millions of potentially harmful batteries -- releasing a gizmo to benefit the medical field, but regardless, we can't deny the impressiveness of the PDW-70MD XDCAM HD recorder. While we caught wind of this thing awhile back, it's now getting official with a full list of specs and a hefty pricetag to boot. Taking high definition recording to a field that can genuinely benefit from more detailed captures, the device can "record and store up to two hours of MPEG2 video on a 23GB PFD-23 XDCAM disc" (wasn't this another failed attempt by Sony's proprietary format department?), which is sealed to help prevent scratches and "preserve data with minimal degradation for more than 50 years." Doctors can store HD video of medical procedures in crisp 1,440 x 1,080 resolution, view colored thumbnails of the footage on the 3.5-inch LCD monitor, and control the action with the bevy of front-mounted controls. Of course, the two biggest factors that prove the PDW-70MD is tailored for medical use is the inability to use a recordable format that the general public can acquire (and afford), and moreover, the $14,995 pricetag that only cash-generating hospitals are likely to glance over.[Via MedGadget]
Accenture developing virtual meal technology, brings videoconferencing to the dinner table
If you're just finishing up what was likely a delicious and fulfilling Christmas dinner with your friends and family, connecting with loved ones probably isn't a problem at the moment, but for elderly and single folks who live alone and far away from old friends and relatives, Accenture is looking to expand their dinner tables as far as the webcam can see. The "virtual meal technology" seeks to aggrandize the dining room beyond a single home, allowing folks to enjoy separate meals while conversing together in real-time. Utilizing the basic premise found in videoconferencing, the plans are to unveil an (almost) automatic system that doesn't require a great deal of know-how in order to operate, with prototypes "automatically detecting" when someone is about to eat supper, and then searching for available family members that would also be interested in scarfing down some grub while chatting it up over the system. The firm is also pushing the medical aspects of such an invention, as it reports that "elderly people who eat alone often don't eat enough or eat the wrong kinds of food," which would allow younger family members to correct those eating habits before more serious health issues develop from malnutrition. While the company hasn't released any draft equipment just yet, it's hoping to have a prototype system available "in around two years," and while it's aiming for the "$500 to $1,000 range" per household, things could get a lot cheaper if your insurance company ends up footing the bill.
Tin foil hats finally find a purpose: Cool-Cap baby cooling
The FDA has just lent its stamp of approval to the new Olympic Cool-Cap from Olympic Medical of Seattle. The shiny little hat is designed to help treat hypoxic-ischemic encephalopathy (HIE -- yeah, we never heard of it either) in newborn infants. It's a potentially fatal injury to the brain caused by low levels of oxygen, and kills 20-25 percent of its victims, with 25 percent suffering permanent disabilities. The Cool-Cap is designed to combat the condition by creating a steady flow of water in the cap to cool the baby's head. It's not as simple as it sounds, with a whole control system involved to monitor the kid, and a solid-state water cooler to deliver uber-precise temperatures to the cap. The foil of the cap is designed to minimize heat, which is great, since it turns out those tin foil hats of ours were never doing much good after all.
Surgical snakebots crawl down your throat
The Johns Hopkins University must employ some seriously bright folks, as researchers at the school are unveiling yet another marvel to benefit mankind, and this time their creation is headed for the nooks and crannies within your body that surgeons have difficulty reaching unassisted. Sure, the diminutive locales within your guts have been explored by robotic creatures before, but these "snake-like robots" could enable surgeons, operating in the narrow throat region in particular, to make "incisions and tie sutures with greater dexterity and precision." The invention consists of two thin rods tipped with "tentaclelike tools" capable of moving with six degrees of freedom; during surgery, the doctor would utilize a 3D visualization system to watch, control, and dictate the robotic tubes. Moreover, the snakes are crafted from nonferrous metals so it can be used around magnetic imaging equipment, and considering its ability to "make up 100 adjustments per second," nimbleness is in its nature. But if you're not exactly fond of such slithering creatures, you've still got time to escape, as researchers estimate that there's still about "five more years" of lab testing before we see Snakes on a Hospital Bed.[Via Physorg]
Sweden develops MICA: the intelligent, autonomous wheelchair
There's not much like getting off the couch and moving around a bit (well, not always), and a Swedish dissertation has uncovered an intelligent wheelchair that sports remote-controlled or autonomous operation. Sven Rönnbäck of Luleå University of Technology in Sweden has developed the Mobile Internet Connected Assistant (MICA), which offers up a presumably comfortable looking set of wheels to those who lack the ability to move on their own. Similar to the technology found in the Good Bytes Cafe, this wheelchair utilizes the built-in "distance-metering sensor to discover the surfaces that are available," and the technology can also be used to "ensure that the wheelchair is being used in a safe manner." The target market is "severely handicapped individuals who would otherwise find it difficult to steer a wheelchair," as these folks could take full advantage of the head-controlled interface in order to instruct the machine where to go next. Best of all, the device can learn and store maps of one's home, giving blind and visually impaired individuals the chance to cart around their crib without worrying over foreign objects foiling their plans. While we haven't heard of any VCs grabbing hold of this marvel just yet, we're sure that opportunity isn't too far away, and we're all about finding new ways to blaze a path.
