(Adapted image from the Conducting Wallpaper patent application.) Besides walls, the wallpaper could be attached to ceilings and floors as well, according to the company’s recent patent application. Electrical devices would connect to the invisible wiring with contact pins, and could tap into a range of voltages, from 1 to 12 volts. The global company hopes that such a system will be ideal for future OLED devices, but could also accommodate LEDs, TVs, multimedia systems, video projectors, lamps, clocks, electroluminescent panels, and more.Philips’ conducting wallpaper is not the first of its kind, but the company hopes that its version can overcome some of the disadvantages of previous versions. Namely, Philips’ wallpaper provides a range of voltages for devices, which can easily be tapped into from many positions on the wall. By repositioning the pins to correspond to specific pitches of the stripes, different voltage levels can be achieved. For safety, the system would likely have a total maximum voltage level of 50-60 volts.The conductive stripes would be made of a metallic material such as copper, aluminum, silver, gold or steel, and receive power from an external electrical supply. The wallpaper, described as “a usual wallpaper or any kind of tapestry,” would simultaneously provide electrical insulation and aesthetic value. The stripes could either be glued onto the wall and covered by the wallpaper, or the stripes could be fabricated into the wallpaper, which would then be glued to the wall as a whole sheet. Philips also suggests a few methods for hanging the electrical devices, such as a double-sided adhesive or a mechanical connection using nails or screws. Another alternative could be a mechanical fastening involving the pins themselves. With wired wallpaper, Philips hopes to give consumers the option of changing the positions of their electrical fixtures without needing to rewire the entire room with conventional, behind-the-wall wiring. The idea could dramatically the change the future of homes and buildings.Conducting Wallpaper patent application via New Scientist Citation: Wired Wallpaper Offers Alternative to Outlets (2008, February 12) retrieved 18 August 2019 from https://phys.org/news/2008-02-wired-wallpaper-alternative-outlets.htmllast_img read more


Google patent calls on eyes to unlock smart glasses


first_img More information: Patent Citation: Google patent calls on eyes to unlock smart glasses (2012, August 9) retrieved 18 August 2019 from https://phys.org/news/2012-08-google-patent-eyes-smart-glasses.html (Phys.org) — In patent language, the application granted to Google this week says simply “Unlocking a screen using eye tracking information” but the message seems clear enough that Google plans to offer a way for wearers of Google headsets from its Project Glass to unlock their systems with just movements of their eyes. The patent describes a number of systems and methods for seeing to it that eye movements will cause the computing system to switch from being in locked mode of operation to unlocked mode, based on eye-tracking information. The technology furthers the ideal of hands-free computing for wearable devices without having to resort to disconcerting gestures, waves, and taps when in public view. Google will benefit in strengthening its past history of coming up with the simple yet innovative for end users. The methods for making the eye tracking and eye movements work include projecting moving objects and displaying a path for the eye to follow. Alternatively, a method might consist of displaying text, and tracking the eye’s movement and speed to determine whether the user is actually reading the text. Reading through lines of text would unlock the device.The patent was filed in November last year but was made public this week. One of the inventors is Hayes Raffle; the other two are Adrian Wong and Ryan Geiss. Raffle is an award-winning product and interaction designer. His title at Google is Staff Interaction Designer, working on Project Glass. Project Glass is one of other projects being built inside the Google X lab near Mountain View, California. His past experience includes a lot of tinkering at the MIT Media Lab where he invented technologies and materials for interpersonal communication.According to the patent, “Methods and systems for unlocking a screen using eye tracking information are described. A computing system may include a display screen. The computing system may be in a locked mode of operation after a period of inactivity by a user. Locked mode of operation may include a locked screen and reduced functionality of the computing system. The user may attempt to unlock the screen. The computing system may generate a display of a moving object on the display screen of the computing system. An eye tracking system may be coupled to the computing system. The eye tracking system may track eye movement of the user. The computing system may determine that a path associated with the eye movement of the user substantially matches a path associated with the moving object on the display and switch to be in an unlocked mode of operation including unlocking the screen.” Explore furthercenter_img Apple bowl-headed patent shows wearable computing plans © 2012 Phys.org This document is subject to copyright.

Researchers build robot rat to induce stress in lab animals w Video


center_img © 2013 Phys.org Scientists have used rats in all manner of lab experiments over the years—sometimes to see how therats react physically to drugs, other times to see how they behave under certain specified conditions,and sometimes to create mental ailments that mimic those found in the human population. Thepurpose of such experiments is to learn how drugs or environmental conditions affect the rats, and then to apply those results to the better understanding of the similar human conditions.The Japanese researchers had many goals in mind when building WR-4. They hoped to understand how mice react to living with a robot, and to theorize how humans might react under comparable circumstances. In addition, the researchers wanted to determine which types of aggressive actions by the robot would induce depression in the rats (as demonstrated by rats that become less active), with the purpose of developing therapies to address the depression.The robot rat is approximately the same size as a regular white rat, and has front legs and feet for steering. In back, it has motorized wheels to help it maneuver. In one series of experiments, the researchers programmed WR-4 to operate in three different modes: chasing, where it simply follows a rat; a continuous attack, where the robot attacks a rat in a non-violent, non-stop fashion for a period oftime; and an interactive attack, where it attacks in a non-violent way only when the target moves. In this study, the researchers found that the interactive attack most successfully instigated the rats’ symptoms of depression.In another series of experiments, researchers stressed rats by putting them in difficult situations, such as having to rely on the robot rat for their food, or having to manipulate the robot physically to get its food.In one test, the robot was programmed to whirl about in random fashion, causing at least one subject rat to attempt to hide.

Highly magnified gravitationally lensed red quasar detected by astronomers


first_img Citation: Highly magnified gravitationally lensed red quasar detected by astronomers (2018, July 26) retrieved 18 August 2019 from https://phys.org/news/2018-07-highly-magnified-gravitationally-lensed-red.html Explore further Astronomers have discovered a highly magnified, gravitationally lensed quasi-stellar object (QSO). The newly found quasar, designated W2M J104222.11+164115.3, is dust-reddened, and exhibits a significant flux anomaly. The finding is reported in a paper published July 14 on the arXiv pre-print server. Quasars are active galactic nuclei of very high luminosity, emitting electromagnetic radiation observable in radio, infrared, visible, ultraviolet and X-ray wavelengths. They are among the brightest and most distant objects in the known universe, and serve as fundamental tools for numerous studies in astrophysics as well as cosmology. Some quasars are obscured by dust as they transition from a heavily dust-enshrouded phase to typical, unobscured QSOs, which reddens their light. Finding quasars during such a transition could help astronomers better understand the processes of galaxy evolution and star formation.A group of astronomers led by Eilat Glikman of the Middlebury College in Middlebury, Vermont, has conducted a search for red quasars by analyzing the available data from the WISE and 2MASS (W2M) surveys. They were selecting objects based on their infrared colors, which resulted in identifying 40 red QSOs. Among the newly found objects was one quasar designated W2M J104222.11+164115.3 (W2M J1042+1641 for short). This QSO interested the researchers as it was more luminous than any other known radio-quiet quasar and implied extreme properties suggestive of gravitational lensing.”In this paper, we report the discovery of a quadruply lensed, radio-quiet red quasar discovered in a search for red quasars using WISE color selection and no radio criterion,” the paper reads.In order to get more detailed information about W2M J1042+1641, Glikman’s team also analyzed observational data of this quasar collected by Hubble Space Telescope (HST), Large Binocular Telescope (LBT), NASA Infrared Telescope Facility (IRTF) and Keck I telescope.W2M J1042+1641 was found at a redshift of 2.517. According to the paper, the quasar has an infrared luminosity of about 120 trillion solar luminosities and is moderately reddened from dust intrinsic to its environment. The researchers noted that W2M J1042+1641 exhibits outflows in its spectrum as well as morphological properties suggestive of it being in a merger-driven transitional phase. Moreover, the quasar showcases significant flux anomaly as its 20 cm flux density was found to be below 1.0 mJy.In concluding remarks, the researchers emphasized that the case of W2M J1042+1641 could be helpful for studies of less luminous, more typical infrared-selected quasar at high redshift. However, they noted that the origin of flux anomalies of this quasar is still uncertain, which should be a target for further investigation.”Microlensing magnification maps may be explored to investigate the possibility of the flux anomalies being due to microlensing. On a longer timescale, monitoring observations would separate microlensing and intrinsic flux variations. Since the quasar is radio-faint, observations probing narrow line emission from the source, too spatially extended to be affected by microlensing, would be required to separate the effects of microlensing and substructure,” the astronomers wrote in the paper. New quasar discovered by astronomers Color combined HST WFC3/IR F125W and F160W images of W2M J1042+1641 over two visits along with output from a morphological analysis with galfit (Peng et al. 2002).

More information: A highly magnified gravitationally lensed red quasar at z = 2.5 with significant flux anomaly: Uncovering a missing population, arXiv:1807.05434 [astro-ph.GA] arxiv.org/abs/1807.05434AbstractWe present the discovery of a gravitationally lensed dust-reddened QSO at z=2.517 discovered in a survey for red QSOs by infrared selection. Hubble Space Telescope imaging in the WFC3/IR F160W and F125W filters reveals a quadruply lensed system in a cusp configuration. We find that compared to the central image of the cusp, the nearby, brightest image is anomalous by a factor of ∼7−11. Although the source is extremely bright in the mid-infrared, a magnification by a factor of ∼50−120 places an upper limit of 1.35 mJy on the intrinsic mid-infrared brightness, well below the WISE W4 detection limit of 6 mJy. We find that this QSO is moderately reddened, with E(B−V)=0.7 and that ∼1% of the intrinsic spectrum is leaked back into the line of sight resulting in an upturn in its UV spectrum. We conclude that the QSO’s reddening is intrinsic and not due to the lens. Consistent with previous red quasar samples, this source exhibits outflows in its spectrum as well as morphological properties suggestive of it being in a merger-driven transitional phase. Depending on how Lbol is computed, the quasar’s accretion rate may be as high as 0.26 LEdd. We detect two Lyman limit systems, at z=2.102 and z=2.431, with absorption by metal lines likely at small impact parameter to the QSO, and a putative lens redshift of z=0.599. Given the rarity of quad lenses, the discovery of this source allows detailed study of a less luminous, more typical infrared-selected quasar at high redshift. © 2018 Phys.org This document is subject to copyright.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Midges are an unofficial classification of two-winged fly. There are many species, most of which are associated with swarms that live near water or marshy areas. In this new effort, the researchers wanted to learn more about the physical properties of swarming behavior from the perspective of an entire swarm, rather than the individuals in it. To that end, they obtained a mass of male Chironomus riparius, which are known to swarm over a given object such as a tree stump as part of their mating ritual—the swarm allows the females to find them from a distance. In their lab, the researchers placed a square of black felt on the bottom of a tank for the midges to use as their orienting object. When the piece of felt was moved, the swarm responded to it. To test swarm responses to it, the felt square was attached to a small oscillating device.The researchers report that they focused specifically on how the swarm responded as an entire unit to the moving object below them. They report that it behaved in a layered manner, with those closest to the moving object responding faster than those in more distant layers. The researchers suggest this was likely due to propagation delays in messaging between individuals. They also observed mechanical properties—and sometimes the swarm behaved elastically, while at other times it behaved more like a viscous liquid—which, in physics terms, meant it was behaving like a viscoelastic material. They also found that sometimes, the viscosity properties were overcome by the elastic properties, which led to an observed dampening effect of the swarm’s overall movement. The researchers suggest this made the swarm more stable, making it easier for the females to find it. They also suggest their findings might have some relevance to swarming robotics efforts.last_img read more

Strangers are sometimes easier to talk to


first_imgI can’t interact with people hence I get secluded in social gatherings. I don’t know why but I can’t make friends. I’m 24, male and am single. How do I get out of this?Tuhin, New DelhiIn today’s day and age it is indeed a bit important to meet and socialize. I suggest, you start spending time with a small group of friends. Make it a point to participate in discussions. Initiate topics that interest you. Start interacting with strangers while travelling. Strangers are sometimes easier to talk to. Start with small talks and gradually weave longer conversations. Good Luck! There’s nothing to lose, just open up!

I’m getting married next month and feel nervous already.Name withheldOne should know the duration of the cycle, i.e. first day of the last menstrual bleeding to the first day of the next menstrual bleeding. This is the duration of the menstrual cycle. This duration varies from person to person and is usually between 26 to 31 days. Ovulation approximately occurs in the middle of the cycle, i.e. duration of the cycle – (minus) 14 days (this also varies). A week before and a week after the approximate day of ovulation is considered to be the ‘fertile’. The days apart from this is called the ‘safe’.Have a love or life query you cannot find an answer to? Send your questions to – [email protected]last_img read more
